Title: Modified roadster construction
Post by: Dynoroom on August 01, 2006, 07:55:58 PM
The modified roadster that Gary Wilson & Mike LeFevers are building won't be ready for Speed Week but we're still shoot'n for this year. Here are some pictures of the cars progress and the power plant. We will run in "C" & "D" gas class and someday with luck move up to blown gas.

Just don't make a mistake and enter that in the C fuel class. Those buzzards will be circling the finish line.

Marvelous project, Mike.

Thanks Glen, glad you like it.
To make a long story short, were working on a way to put front suspension in it. It's currently solid, we don't have enough room so to get the car done we just said "Bolt it down"(ya we know better). Now that were not going to make Speed Week we are going to re-investigate our lay down shocks & rocker arm front suspension. We always wanted it just time & room issues because we want it all on the inside of the body.

I have some suspension pictures on this page you might want to look at:

PS - I owe you an apology. I gave you a short answer to your question about the Honda F1 car using TC. The truth is I didn't ask but, I think it was turned off from the sound of driver's pedaling.

Some more of the belly pan & chassis etc.
Gary's been doing most of the fab work, I just kind of get in the way as I learn how to do things other than engines  :lol:
It truly has been a learning experience building a land speed car from scratch, lots of work but you all know that!
Later I'll try to post pictures of the water, fuel, & dry sump tanks, along with the steering & other details.

Tom this unit does not overrun when you "pedal" the throtle. It has the same type of dog rings as the 4 speed we used in the #265 Firebird and does not fall out of gear.

Mike

Did you make the seat, or is commercially available?

John

John the seat is a standard unit made by kirkey and cost about $150. It was a little to tall for our cage so we cut it down about 6".

Thanks for asking.

The dragster is a recreation/restoration of the Norman Gingrass & John Dearmore 1968 AA/FD out of Wichita, Kansas. It is currently owned by Larry Crossan of Sacramento.

BUMP!

OK, you guys know it takes lots of Time, $$, & work to field a race car. This car has been a test of wills, but we're  making headway.
I started a thread a couple of weeks ago about laying up fiberglass because I'd never done it! Well the fact is I should keep trying to build engines because I sure can't do glass work........
Anyway here are some pictures of the parachute faring for our modified roadster. As you see we still have tons of fit and finish work to do. Ahh Bonneville, you'll do whatever it takes.

Mike---that is what sanders are for---a nice "1st" attempt---bet it will look as great as the rest of the car with paint on it!!!!!!!!!!
Title: Re: Modified roadster construction
Post by: Sumner on April 27, 2008, 10:00:28 AM
Looks good Mike.  I can't tell you much about the stage you are since I haven't done glass, but I would go with the coarsest disc you can put on something other than the end of your arm and knock that down in the vicinity of flat.  Then don't be afraid of more bondo than you would put on a street car.  This is a race car. 

With the bondo at first you aren't sanding it you are shaping it, so use 36 or 40 grit on a long board and this new stuff will knock down pretty fast.  I have an air long board, but haven't used it in years.  I would recommend a hand one as it will go fast and you won't be taking too much off and having to keep putting more on.  Don't be afraid to use a "guide coat in a can" at this step.  It will let you see the highs and lows and will let you go much faster.

Once you have the shape with the coarse paper then put on a very thin skim coat on and knock the highs off with 40 grit and then sand the 40 grit scratches out with 80 grit.

Once you are satisfied with it after sanding with the 80 grit go to a high build catalyzed primer and put on 3 heavy coats.  It will fill the 80 grit scratches and you can block that down (guide coat it) with 180 or 220 dry.

Finished with that put on 3 more heavy coats and block it with 400 wet.  Don't sand any of these steps with your bare hands on the paper get some different rubber blocks.  A hard one for the last step and there are some that are hard on one side and soft on the other for working inside curved areas.  Get a long board and shorter board to use with the 40, 80 and 220 papers along with the blocks.


When sanding with the 400 paper I wrap it around a paint stick and sand, then tear off a length of it, sand some more and tear until it is all gone.  Put the paper in your bucket of water with some dish washing soap before you start using.  Take a sponge and keep dipping it in the water and wring the sponge above where you are sanding.  Dry the area every once in a while with a squeegee and paper towels to see if you have sanded it flat.  At this point you aren't shaping anymore, just getting ready for the top coats.  After the 400 you can spray the sealer and top coats.

This all sounds like a lot of steps, but once you know what you are doing you could finish what you have in the pictures in a day and be ready for paint.

I like the effort you have put into getting the cage over the driver's head as low as possible.  There are a number of cars that run that could sure benefit from doing that.

c ya and did you ever see if I have everything on the site like you wanted it?

Hey Dynoroom and crew, :-D

That thing is looking plenty good! 8-)

Glad to see and hear that you are making some progress on your stuff. That sure makes the time pass with a reward at the end. :roll:

Even though it is not a requirement, you might consider a heavier section of armament over the top 180 and front of the driveshaft to well past your hocks. Attaching to the loops, the piece could be removable for working on the car if necessary, but shrapnel is never your friend no matter where it comes from. :|

Mike,

This is my first look at what you have done.  I think you did a great job on the glass work.  When we talked on the phone, I had the impression it was a much smaller piece that you were working on.  I like the way you carried the theme from the front of the car into the shape of the fiberglass piece.  Looks to me like you know what you are doing.

Hi Mike and All, :-D

Nice finish lines on the mod roodster. Are you planning on using a mini chin spoiler under the flat panel? Like something that is within 1/2 inch of the salt surface or something like that? :lol:

What type of arrangement are you going to cap over the carburetor? I am assuming some type of scoop device. :wink:

Looks like I came to the right place.  I'm an old drag racer.  Started in 1961 with a '51 Chevy, then a '56 Chevy, & '63 Chevy at Lions, Colton, & Irwindale.  Street beaters.  Became a gofer for the Barlag & Clark T/F car in 1964.  After the Navy, with Gary Jennings, built a C/GD, then an A/FD, then an AA/BAD.  Ran that until 1983, ran out of $$$, backed it down to run the S/E club races until 2005, when Gary had his first, & last heart attack.  Tried model airplanes, naawh; tried a sail boat, naawh.  Went to the first El Mirage show last year.   It was hot, windy, dusty, & long.  At the end of the day I was sunburned, smelled like sweat, dirt, oil, gas, & nitro.  As I was leaving, I bought a rule book.  Went to all the meets at El Mirage last year as an observer.  I have gathered enough parts to build a Class G modified roadster, except for the body, & chassis.  I am not going to light a torch until I know what I'm going to do.  I would prefer a front motor car, but a back motor car is easier to build.  I have built both.  With a front motor dragster, the driver hangs out behind the rear end.  Not so with a front motor modified roadster, as the driver hangs off to the left side.  I would like to see more pictures of front motor modified roadsters without the skin, to see how the cage is built.  Any advice is appreciated.
John   :cheers:

Post by: Dynoroom on January 11, 2009, 10:28:40 AM
Welcome John. Here are some shot of out early chassis construction.

As for advice the only thing I suggest you look as is driver placment. If I was to do it again I'd put the driver on the right side of the car. When running at El Mirage the right side of the track is not run on as much because most drivers can't see how close to the edge they are. Better dirt is dirt that hasn't been run on.

Good Luck on your project.

Thanks for the pics.  Theyr'e extreemly useful.  I was kind of lerry about sitting next to the driveshaft,   however, in all the dragsters I've driven, except one, I had the driveshaft, trans, & rear end between my legs.  Not much difference, is it ?  What is really helpful is seeing where the driveshaft goes, & that the back of the cage is even with the CL of rear end.  I found another M/R on the build site from Bob Sights Jr.  I used to race against him, & Nick Arias III in the 80's, & his has a similar setup.  I've pretty much decided on a front engine car, as it will fit in my garage, & on my trailer. 
By the way, your car is reminicent of the 1960's, & 1970's T/F cars.  Magnificent craftsmanship, body work, detail, appearance, & performance.

Update!


I said that I would try to update the build diary but I didn't think it had been so long since I posted any info.

So in a nut shell......   we ran the car for the first time at Bonneville '08. Both of my sons wanted to drive but the youngest Kevin fit the car best @ 5'10" his brother Ryan is 6'4" and had to wait until we made changes in 2009. Nither had ever driven before so this was a license and learning time too. Both boys have earned their "A" license's and now race at El Mirage starting in 2009.
We've not been able to run as well as we'd like at Bonneville yet but in 2010 Kevin missed the class record at El Mirage by less than 1 mph. Then at the opening May meet in 2011 everything clicked and Kevin reset the 208 mph record to 213 earning entry into the Dirty 2 club. We finished the 2011 season as LSR club points champs and set top time of the meet in Sept. So it was a good year. Now we are going to focus on getting Ryan a shot at setting a record and working the issues out of the Bonneville setup dynoing the engine with the complete fuel system in the next couple of weeks. After all I do own a dyno......

First picture first race at Bonneville 2008

Second picture is from 2011 at Bonneville

Third shot is from El Mirage

  Mike, not only is it a great looking car, but to be able to share your knowledge and expertise with your sons has got to be one of the greatest feelings one can enjoy.

A couple other things we're doing for the 2012 season is making some adjustments in the 4-link, Re-dynoing the shocks to get a better handle on some of the settings, and I'm working on a new intake manifold that I hope to make multi-purpose with either multi-carbs or EFI and even a provision for a throttle body on the front for when we turbocharge it.  8-)

That intake looks very cool... Are you planning on building in provisions for carbs, then plating
when running EFI, or building a separate upper to adapt to the fuel system? Very cool stuff. Is
that a T6-flanged turbo? Looks very similar to our Bullseye S488. Great looking car, all around.

Jan. 2013 Update

We are building a new fuel tank as the new intercooler water tank (also shown in mock up) sits in the place of the old fuel tank.

We are also building new stainless headers (not shown) to merge into the single turbo.

These pistons have a ceramic coated crown and a teflon coated skirt to along with the 1.5 mm laterial gas ported top rings and some of the other "tricks" of the turbo trade.

The Garrett "indy" wastegate is water cooled which is a good thing for running at Bonneville but it's as big as a club! This might make it a tough job to package in our chassis being we're going to use two. So we are also looking at a smaller pair that should do the job if needed. 

The fabricated intake manifold is progressing be it slowly. Lots to do and a short time to do it!

Title: Re: Modified roadster construction
Post by: Dynoroom on March 25, 2013, 07:09:30 PM
More progress. Lots going on. Here are a few updates.

The switch and gauge panels were reworks for a new boost gauge and a different shift light. The switch panel has more toggles now along with new circuit breakers.

The collectors from my friend Jack Burns at Burns Stainless are works of art. I will post pictures of the 321 stainless headers shortly too.

The stainless intercooler water tank is finished now I need to finalize the mounts for it.
The fuel tank is also stainless but about a week away so I'll post pictures of it when done. I need to really thank Bob Dalton at D & A for the help with the tanks amongst other things.

Found a simple place to mount the ECU, boost controller, and MSD 7AL too, so like I said we just keep plugging along.

Mike, I have been looking into coatings and just cant get my hands around how they spray an even coat.  Does that mater much or is there something more I am missing? I remember in the old IMSA  days talking to our engine guy from  Roush, and he would say they would go through a bunch of sets of bearings after coating them to find enough shells to make the perfect set. Tony
Title: Re: Modified roadster construction
Post by: Dynoroom on March 26, 2013, 12:58:27 AM
Tony, I don't coat bearings but I have used them. They do have a build up but bearing shells very in thickness from the parting line to the center of the shell anyway. You measure for clearance just like any other bearing. That being said if you ran a standaed bearing uncoated you might need a extra clearance bearing if it's coated. I don't see the need, and many of the Nascar engines I've worked on don't have coated bearing either.
I do like coated cam bearings because of the spring loads during startup.

Title: Re: Modified roadster construction
Post by: DND on March 28, 2013, 11:55:21 PM
Hi Mike

Do those cast flanges stay flat when welding, when using a single flange you can hold it in a fixture for a final mill cut to make it flat for the gasket seal.

What do you do with those type of flanges for flatness?

Those parts do make a nice & clean looking header, does the collector stay floating?

Stainless is neat to weld just like welding butter just flows and looks great after with all the colors in the weld to see.

Don,

Yes they stay flat after welding, and if not a simple touch up on the 20" disk sander fixes any issues. We don't use header gaskets and yes the pipes "float" in the collectors. I've been involved with endurance turbo engines for over 30 years, many on the salt and the current method I use has worked out the best for us to date.
Thanks for asking.

I would be interested in what the top plate looks like for your manifold, I hope it is either thick or has some "crown" to it plus really thick flanges, at 20 lbs of boost there is a lot of force trying to "balloon" your manifold, especially the top plate.

Rex

Update on the modified roadster with a fast approaching Bonneville Speedweek.

First, to answer the question about the thickness of the lid on my intake manifold. It will be 3/16" or 0.187 which ever is thicker.   :wink:
If you look at the 2 pictures I posted you will see a couple of fabricated intakes similar to what I'm building. They both run on turbocharged engines. Both of these engines run at Bonneville with over 20 lbs. boost. Both have set many records and both have run over 300 mph. The second one's even run over 400 mph!
From an engineering standpoint the lid should be rounded or bowed, but in the real world that we race in it works fine like this...... for a limited amount of time anyway.  :cheers:
Title: Re: Modified roadster construction
Post by: Dynoroom on June 13, 2013, 01:46:48 AM
Here we are trying to get all the things done that need to be done to convert a normally aspirated engine into a turbocharged engine.

First picture shows the layout from the front of the car. Fuel tank, intercooler water tank, and the charge-air cooler. Both the fuel and water tanks are stainless, thanks again to Bob Dalton at D & A   :cheers:

Next shows the mockup engine with the intake manifold and the wiring harness for the EFI (ran a carb before) and some of the placment of other items.

The next picture shows the exhaust out of the turbo. This part is all fabricated, nothing but the v-band flange is used as is due to packaging, still in process but the magic of long time friend Kirk Harkins.  :-)

Next on the list is the wastegate exhaust layout and about a million other things. I might even have all the parts for the engine in the next week or two. Of course then the dyno thrash begins.....  8-)

Oh, in 35 years of running turbo cars on the salt I've never run a BOV (blow off valve). This engine will be no exception.....  :-D

Hi Mike

Looks like 2 waste gates does that give you better throttle responce?

Don
Title: Re: Modified roadster construction
Post by: Dynoroom on June 14, 2013, 10:20:39 AM
Tman,
the BOV issue is simple (at least to me). The BOV (blow off valve) showed up about 20 years ago. The turbocharger itself has been around for over 100 years now. All the years before the late 1980's and no one knew they needed a BOV. I know that turbos have advanced, but I still use the basic designs (a whole nuther subject) in my system builds. I don't need ball bearings, ceramics, thin quick spool shafts or any other trick stuff. So for me, no BOV required. I have many engines running and setting records on the salt with no BOV so I'm okay without one. I also feel it's something that you get sold on because you "got" to have it. Well in some applications you do, just not mine.
I guess it also means I'm just a stubborn old guy.   :-o

Don,
the two wastegates are used here due to the mass flow of the system. I felt a single 44 mm gate would not flow enough to allow for the staged boost control I want to imploy and would also contribute to "boost creep" where the boost pressure keeps climbing beyond the set point because you can't remove enough heat or pressure. I did have a larger wastegate that would have worked as a single unit but packaging became the issue for me.

Thanks for the lesson as i'am learning as i go along here, was around Bob Pattersons Unlimited Hydroplane 30 yrs ago and learned a bit.

Kind of a different animal since the Turbo Allison is 1710 cid and had to have a ton of air going into that beauty

All of the engines i built for 20 yrs were unblown , but the last one had a 6 on it for street rod and i told him to be very carefull but he wrapped it around a pole playing around smoking the rears

Plus i'am learning form Tony and his turbo GMC 6 roadster

Well work continues at a fever pace. Here is Kevin working on wheeling the "power dome" aka the engine bubble. He's about halfway through this little task. I'll let you guys ask him how much time he has invested...

The crank is laid in the block and the basic assy should go smooth as the engine has been together before. I hope to finish the long block before the weekend. Now the accessories on the outside might take a bit of time to fit up. Then we Dyno test and map the engine. Remember, we ran a carburator before now it's a turbo and efi.    :cheers:

His engines bend the needles on the dyno.

There is a great line of records behind him.

That includes the Dirty 2 Club for the kids.

The engine is in the car and the turbo system is installed. The fuel, intercooler and intercooler water tanks are installed.
Just the wiring (just) and a few hundred other small details and we'll be ready to go......

Bonneville 2013; Nothing to it!

For everyone who makes it to Bonneville for Speedweek, my hats off to you. Just the trek to the promised land of speed is a huge undertaking. If you put a tire to salt in anger you understand the tremendous amount of work it takes to field a race vehicle; be it car or bike.
The event itself that's put on by the SCTA/BNI is almost as hard to imagine being put on by a small but dedicated group of volunteers, simply amazing. Thanks to every one of you.
Our visit to the "Great White Dyno" was less then stellar. No mater how well you have or haven't done in the past at Bonneville it needs to take its pound of flesh from time to time. This year the good was minimal waiting when you arrived to the starting line. The bad was the record number of spins & several crashes with drivers/riders getting trips to Salt Lake City. Thankfully, everyone seems to be mending well.
So now for our little adventure: We made a checkout pass to the 3 Sat afternoon to make sure the new turbo system didn't melt anything or worse! The pass netted us a 217 mph 1/4 and a 219 mile. Not bad but something didn't seem right on the data log as the engine was on the rev limiter with no boost the last 10 seconds of the run. Further checking led us to a clutch that would not disengage. After checking around we were able to borrow a 3 disk clutch from Wayne Jesel to replace out 2 disk unit. We also borrowed a really nice engine “A” frame puller from the Mariani Team. I want to stop here and say “Thank you” to both Wayne Jesel & Dennis Mariani. This is what Bonneville is about.
After pulling the engine (just a side note here, I had always said I’d never pull an engine on the salt. All the tools I’d need would be at home, especially with a turbo motor.) We changed the clutch and had it all back together and running in about a day and a half. So now its Wednesday 5:45 pm and we get to continue our little misadventure. The courses were staying open until 7:00 pm. But the fuel truck closes at 6:00. So too the ice truck (we need ice for the intercooler) so I have Kenard Deeds run into town for ice after scouting which course had the shortest line while racing to the fuel truck to top off with gas. After getting to the line, adding ice to the intercooler, getting the driver belted in, it was 6:50. Start the engine and I realized I had left the intercooler pump running for the last 15 minutes or so. Well this is not part of my tune up; so the engine was hard to keep running and as Kevin drove off I could see black smoke from the exhaust. Shortly after it backfired pretty hard and Kevin shut it off not sure why it was doing weird things.
So Thursday morning we go through our standard check out and warm the oil to start the car. Well now it won’t start. Traced it to the ignition system but with all the issues on the courses traction wise and our lack of time doing the check outs we wanted to do it was time to call it a meet.
We see lots of promise in our turbo package and feel lucky to have made it to race. It’s not as easy as many people think to run on the salt. Many of my neighbors did not fair as well as us. The team next door dropped a valve on Sat after setting 2 records at El Mirage earlier this year. Another team a few pits over sent the rods out of the block, and yet another over heated and grabbed a piston. So our car came home got cleaned up and I’ll fix the little issues we have and carry on. We might just run El Mirage and see how that goes.

I need to thank several other companies and people.
Edelbrock Data & ECU, Lucas Oil, Jesel Valve Train, Burns Stainless, Arias Pistons, Centerline Welding, Performance Solutions, D & A Engineering, BPE Heads, Isky Cams, Kirk Harkins, Jamie Wagner, Bob Dalton, Dave Isley, my sons Ryan & Kevin, and the one who tolerates all this madness, my wife Judy.
I’m sorry if I left anyone out, there were so many people who helped in so many ways.
“I Thank You All”

i can't begin to imagine the Father's pride as he works with two knowledgable and talented sons.

I experienced it one time in Hawaii as my son, Gary, and I struggled under the fuselage of a

Hughes 500D helicopter as the rain pelted down on us while we attached two motorcycles to the

skids of the chopper. I was jammed and Gary said to me, "No problem Dad. I've just about

finished this side and I'll get yours." I turned back to my challenge and it went together like it

did when we made the brackets.

What goes around comes around and when it's our kid that is alongside of us during a

challenging time..........ain't nothing better for old Dad.

And I qualify as "old" Dad. Mike is a talented young Father and the kids must still be

teenagers.

So what did Ryan and Kevin do after they loaded up? They went and volunteered as

course workers.

The whole family is headed in the right direction.

Judy and Mike.......ya done good.

Mike some of my best memories from my teenage years are of the time I spent working on the family dragsters with my dad. As I got older and was able to buy my first race car, the first person there to help me was my dad. I learned a lot from my dad and I truly appreciate it. Im sure your boys enjoy their time with you and the knowledge you are passing on to them. Remind them how lucky they are that you turned over the keys to the family hot rod to them at such a young age, it took my my racing operation getting stolen and me being in my mid 30s before my dad let me drive their car  :-D

Sorry your Bonneville trip wasnt what you had planned but you learned some things and didnt tear up the car. Hope to meet you guys if you run EM in November. Passed by your pits but you guys were busy turning wrenches and I didnt want to bother you all.

Post by: Dynoroom on March 18, 2014, 12:36:46 AM
For those who followed our progress getting ready for Bonneville 2013 thanks.
This will be an update showing some slight changes we will be making this season to improve either engine performance or access to components to making the car easier to maintenance or work on.

This first series of pictures shows how we moved the fuel pump to solve a hard to start engine due to vapor lock after warming up the motor before a pass. I have run many engines with the fuel pump mounted on the back of the dry sump pump. This time the headers got too close to the fuel out fitting causing vapor lock (See the first two pictures). So we decided to make the fuel pump a cable drive unit thus moving it away from the heat of the headers. We moved the oil filter and machined the "mid" mount motor plate to accept the fuel pump adapter and drive assy., next two pictures.

Trying to post more info but the site tries to help keep us from re-posting so it really makes it....... interesting sometimes......

Next up is the boost tube. Seems simple enough but to get it to fit the car with our packaging it needs to pass directly over the turbine housing. We have a heat blanket on the turbine but the boost tube more or less laid on the blanket. This of course is not a good thing so a rework of the boost tube is in process. Pictures (showing my lousy fab work) soon to come.
Here is a picture showing how it was......

More to come, El Mirage is in May!

Our charge pipe lays directing over the center bearing section; even with a blanket there
is definitely some serious ambient heat present. I would imagine the super cooling of that
A2W intercooler probably makes up for any major build-up. What kind of IAT's did you see
running last year?

Post by: Dynoroom on August 21, 2014, 01:25:09 AM
Ok, we had the car ready for Bonneville but......... ahh Mother Nature.

I was busy with a few details & projects along with the scoop so I didn't get as many pictures as I would have liked. Good thing really as it kinda turned into a POS. Anyway I cut the scoop in half length wise and hollowed out the center to hold the aluminum inlet tube. Then I laid some glass over the foam after I thought I used a resin that wouldn't affect the foam. Think again; as I was laying up the fiberglass the foam was falling away underneath. I went ahead & finished the layup, bondo, mounting & paint in time for bonneville but since it was ugly & the event canceled I've taken it back off to fix (I hope) the details I didn't like before. That being said here are the pictures I do have of the job.

I have other pictures but they must be on the computer at work. So more later.

Mike,
     Here is how I did mine. I decided to mold the inner contour as I wanted it to be as smooth and fair as possible. I made a plaster splash of the hood contour and laid some glass on that to make a base for the plug. The shape was band sawed and sanded to fit the base and epoxied to it. Then sanded smooth, sealed with a two part paint, filled, sanded, spot filled, sanded again and painted.
     The plug was waxed, and painted with polyvinyl alcohol and laid up with  three plys of cloth/epoxy resin. I used carbon fiber because I had some left over from making the inner fender wells for my brothers  streamliner.  Standard bondo, sand, prime and paint for the outside.
     It mates up with a plenum I made to fit around my injector.

Boost controller is hooked up, Air scoop has been fluffed & buffed, Intake air temps were showing some issues so we'll see if we got that under control along with a few other details.
We will also be adding an access door to the hood before next season for the addition of ice to the intercooler tank without removing the hood in the staging lanes.

Well, things are starting to move in a positive direction. We took the car to El Mirage this last weekend to see if we could gather some more data. Kevin was again driving with a low boost setting (~7 psi) to see that things are working correctly. We have had some issues with the fuel return, under hood temps, charge-air temp, etc. The pass was good at 202 mph as we only have 3 full passes so far & Kevin is still learning how to deal with the added power.
The new design boost tube with better air gap & shielding over the turbine housing appears to have solved our temps climbing in the intake manifold. The new air scoop "seems" to be ok but we need more testing to make sure. I installed a manifold absolute pressure sensor in the ducting to the turbocharger. On acceleration it pulls a vacuum at low speed and starts to recover pressure at 200 mph. This was close to the calculations but we need a faster run to prove it IMO. A couple sensors (drivrshaft, TPS,) to name two may need to be remounted to better deal with some erratic readings. We can smooth them out in the program but I think the mounts are the issue. Some other small details are water temps too cool & oil pressure to high during the pass. One may be contributing to the other so we'll sort that out.
Overall a very nice weekend on the dirt, you don't get those to often. Upper 70's low 80's & no wind.
Anyway, that's kinda it in a nut shell. If I think of anything else I will post it.

A few simple things to make the car easier to service. We added a trap door to the hood (which I hated to cut into again) to make adding ice to the intercooler tank something we could do in the staging lanes without removing the hood, a two man job. I was always worried someone might drop it, run into something, step on it, who knows what.
So here's what we did....

I would like to say thank you to everyone who has followed our build thread for the last 8 or so years. We hope it has given at least one of you out there the desire to build a vehicle of your own...
I would also like to thank everyone for their kind praise & insights on our family project.

We were ready to go to the opening El Mirage meet of the 2015 season but for whatever reason it was not to be.
I keep a running note pad of items that need to be done for the next meet along with a list of things "to do" someday. Since the May meet was canceled we had time to install a engine vacuum pump that we had bought late last year. We needed to build a custom mounting bracket, special pulley so the pump would work at it's optimal speed, along with mounting the catch can, built lines, etc.
Here are a few pictures of the install.

 
Title: Re: Modified roadster construction
Post by: Dynoroom on May 25, 2015, 12:59:23 AM
A few more...... The large pulley comes with the pump & is designed to run off the crank but we were going to run it off the water pump so the vacuum pump speed would be too slow. The smaller pulley will allow the vacuum pump to run at it's optimum speed.

See you at the races!

Racing is a series of "problem solving" events that allow you to spend money & make noise...

El Mirage Report from last weekend.
First run was a turn out as "I" forgot to check a sensor connection that "I" told myself (& others) to check when we got to the lakebed. You can see how that worked out....

Then we ran into an interesting issue on our 2nd try. Seems we had a tygon hose in our air shifter burst. We had this happen a couple of yeas ago but though it was due to some mig welding slag. Not so. All the shifter servos are on the left hand side of the transmission. Then the numerous air lines that control the shifting are on the left side of the servos. This encroaches on the drivers compartment and the aluminum panel that separates the driver from said hardware (pictures to follow). Well it was about 112 degrees Saturday afternoon & these hoses rest against the aluminum panel. Well, it seems with the sun beating down on it the hose got soft. Then when the pressure was applied it popped like a balloon. Transmission falls out of gear & engine goes on the rev limiter. Hard to go fast in neutral. Good news, nothing was hurt but our pride.
Moral to the story... Don't forget your umbrella to cover the drivers compartment from the hot sun! We also added a heat blanket over the lines & installed a heat pad on the panel. For those of you who will say "use Teflon braided lines" look closely at the pictures. Not a lot of room to install any other type of hardware. 

First picture is the interior panel with the bulge to clear the a servo.
Second picture is the transmission side of the same panel & the servo.
Third shot shows all the lines and the routing we use in the car. Jerico has a different routing but it won't in our car so we changed it.

Mike did you add a vacuum gauge to your pan or valve cover? I ran a pump for 5 years before I did and it a glance at thing before the lights if I remember; a nice thing to know for a guy not running any data acquisition. Easy to do at the salt not so at El Mirage. I like your brand choice on the pump. I feel Aero Space Industries are the best at least for me. I check the reciever after every run; I use a petcock on the bottom of mine for this.

Put on your check list, a couple of squirts of oil in the pump before you run 5 miles. They will burn up w/o oil.

Thanks everyone! JD, we record crankcase vacuum. I also set the vacuum brake in the shop before I put it on the car. Your opinion of the Aerospace pump in similar to mine, easy to overhaul too when the blades wear down.
Toclub, yes we know to add oil from time to time but it does put a fair amount in the catch can too.

As a side note my view of this thread will be the 40,000th.....  Thanks!!!

Mike,
Just a quick question on if your engine has a "tight" seal, i.e. do you have any openings between the engine case and atmosphere other than the leakage past the piston rings? I ask because if the pump is trying to evacuate from a sealed container it will not provide the best vacuum. As I understand you should have some sort of orfice that connects the case to atmosphere and this will keep the pump drawing the best vacuum. Obviously you will need to experiment with the orifice size to optimize.

Excellent question Rex!
Yes, we have a vacuum brake that is adjustable and also has a small orifice for bleed air to the pump. If you look closely at the pictures you can see the brass filters under the diaphragm hat. We are running about 18" of vacuum currently.

Title: Re: Modified roadster construction
Post by: Dynoroom on September 23, 2015, 07:57:25 PM
For those of you who use Co2 in your race car to operate systems like shifters etc. think about this.
When we built the roadster we decided to use an air shifter to make driving easier. Just push a button on the steering wheel so no hunting around for the correct gear & both hands stay on the wheel. This can be important at El Mirage when you start running over 200 MPH on dirt. Anyway, we thought we'd carry the idea (keeping your hands on the steering wheel) a little further. So we added an air servo to pull the parachute  cable open after a pass again without taking your hands off the wheel. 

So, the button on the right side of the steering wheel is the shift button. Every time the shift light comes on (or at X RPM) push the button for the next gear. The button on the left side of the wheel is the parachute release button, again the drivers hands never leave the wheel once the run is underway. The red "T" lever in the center of the steering wheel is the emergency parachute release (required by the rules & a good idea anyway) so if you should loose air pressure for any reason you have a manual back up. It has worked well for us as the car has tried to spin once at Bonneville & once at El Mirage. Both times the pucker factor allowed the driver to hit the button as a spin started, the car never made a complete 360 because the 'chute was out soon enough to catch the spin & pull the car back straight. I feel this is much better & FASTER than taking your hand off the wheel to reach for a lever.

The second picture you can see the actuator that pulls the parachute cable in the lower right corner with a black air line going to it.

For those that might be wondering, the panel on the right has several switches & such so from front to rear:

Master battery on/off with a cable to the rear of the car for the emergency team

Next is the master transmission engagement switch

The orange rubber coated push button is for the starter

Then 3 toggle switches with safety covers for the ignition, intercooler pump, & priming fuel pump

This is followed by 2 fire bottle knobs

Below those is the plug in for the oil tank heater.

   
Title: Re: Modified roadster construction
Post by: Stainless1 on September 26, 2015, 01:28:00 PM
Mike, been preaching the same approach for years.  If you have to reach for the chute it will be hard to get it in time... we also shift from the wheel, with the up shift and down shift switch next to the oil pressure lite and mechanical chute pull. 
Our wheel... the shifter is on the lower left, the chute is the "guarded" button above it.  The button on the right is for those crazy times you think N20 is required.

Post by: Dynoroom on December 02, 2015, 03:54:17 PM
Well, that's it for the 2015 racing season. We ran 205 mph at the Nov. El Mirage meet. Then melted some wires after the pass.  :oops:
We have been struggling with this new turbo combination so we're going to yank it out of the car & beat it up on the dyno over the winter. I have been running record setting turbocharged engines at Bonneville since the early 1980's, this one is not going to get my goat...  :dhorse:  or horse...

We have a new list of upgrades for next year, so we'll be back ready to kick some tail next year.
We will also try to post updates with any modifications we do over the winter.   :cheers:

Well, as Speedweek gets closer & it looks like we might even have a Speedweek this year, I thought I'd better fix some nagging little issues. The engine would run fine on the Superflow engine dyno in my shop BUT in the car we kept having electrical problems. So off to the chassis dyno to test ALL the systems as they run in the car. Lets see how that works at Bonneville in 4.5 weeks!!!

Besides, I know you want to see her nekked  :-D

Mike,

You probably know and have checked this already, but here goes . . . .

In my experience of every instance like you describe above, the problem was resolved with a ground "buss bar", eliminating electrical issues stemming from irregular or intermittent grounding.    The ever present corrosion on an salt driven vehicle would play hell with obtaining consistent voltage, in my opinion.    Had a Trans-Am Corvette that was a consistent performance problem until the owner/driver (who was a certified electrician in his "day" job) added a "buss bar" the electrical system.   Problem solved.

Regards,
Mark

I really have to agree with Mark  that nothing is harder to find and easier to fix than a bad ground. You cannot have enough of them! I have worked on every thing from Indy cars to giant CNC machine tools and they all can suffer from bad grounding and your discription of how it runs great on the dyno and has problems in the car just screams "grounding problems"! Of course all of this means that the real problem is in the fuel system!

Today we built & installed a simple tow bar to move up & down the salt a little easier. Pushing the car required someone to be in it to steer & brake. Now we can debrief on the ride back to the pits with the a/c going.

Regarding the above comments, We did indeed add more grounds to the car before we went to the chassis dyno. I think we solved those issues....  :|

We have had good luck with big, low, mud flaps on the tow truck.
Title: Re: Modified roadster construction
Post by: Seldom Seen Slim on July 13, 2016, 10:40:49 AM
Quick tangent:  On our pickup I use semi-style mudflaps cut to fit.  I let 'em hang to within 4" or so from the ground, and the flaps I use are the kind that have "nubbies" on the tire side to help reduce spray.

Caveat:  With that little ground clearance you'll need to be careful when backing over stuff, like a curb.  They're easy to pull off.  That's one way to keep the fasteners fresh - replace 'em each time I rip off another piece - of mudflap, that is. :roll:
Title: Re: Modified roadster construction
Post by: Stan Back on July 13, 2016, 12:14:46 PM
We use what might be called a "brush" that you see on motor homes.  I cut it down for width and height and it's attached with just a couple of bolts to make easy removal when at home.  It's flexible enuf if you run over something or back into something.  Same one worked for years.
Title: Re: Modified roadster construction
Post by: mc2032 on July 13, 2016, 03:18:10 PM
Check craigslist for "Rock Tamer" style/brand mud flaps or similar.  I scored a set locally for half of nothing.  Has a built in bracket that slips over and bolts to the draw bar prior to slipping the draw bar into the receiver hitch.  Easy on/easy off, adjustable and designed to keep stuff off what is being towed.  Heck, you might even be able to build a set based off of the design.

BONNEVILLE SPEED WEEK 2016


Well, we’ve had time to get home, clean our equipment, & catch up on some rest from the vacation we call Bonneville.

I’m really disappointed this year. Mainly because it’s been 2 years since we have been able to run yet we still stubbed our toe. If you remember we went to the chassis dyno in early July to make sure the corrections we made to the car were valid & we could start to improve on our past lack luster Speed Week performance.

Not gonna happen. We made 3 attempts to get down the course. The first two tries were turn outs, we couldn’t run fast enough to get out of our own way. The last run Kevin said the hell with it, and stayed in the throttle until the end of the first timed mile. That netted a lowly 191 mph. Disgusted is an understatement.

We feel the condition of the salt & access roads contributed to our issues. The car ran well during dyno testing but the bouncing & banging the car took on it 3 mile ride to the starting line seems to have effected our low budget wiring harness. We constantly had intermittent electrical issues that kept cropping up affecting our performance. Everything seemed fine in the pits but not so on the course.
These types of problems are not only frustrating, they can be almost impossible to track down. I think our only choice is a professionally constructed wiring harness. Big $$$ but so is going to the salt & not running worth a damn.
So there you have it, another years effort only to be no better off than last time.

I have already made contact with a competent racing wiring harness builder/supplier in the off road arena. We will take the car in for a complete custom harness then head back to the chassis dyno.
No one ever said Bonneville was easy...  But we WILL be back!

Sorry to hear of your problems but it was great to finally meet you at the salt! The G/FL tank that I was with, Steve Nelson's no. 221, didn't like the rough conditions also. Steve turned out at the 4 on our only "good" run because of the rough salt. The car has a solid rear suspension and it really was shaking and wondering around so he turned out. We hurt the motor on that run so that was it for the week. Next year!

If we have a track for 2017, we will see you there with another G/GL - G/FL. I think I have talked Stainless into putting in the "big" engine and that would make at least three lakesters in un blown G class. More the merrier.

Mike,
     Does your transmission have a breather and if so what kind?

Yes we do Jim. The top photo shows a blue 90 degree 3/8" pipe fitting. The next photo in the lower left you can see a small K&N filter connected to a 3/8" aluminum tube that connects to the blue fitting in the top photo. Not the best pictures but it's what I already had in the computer.

I guess it was common knowledge -- but not for me.

When we first ran our roadster years ago, I trusted the stock vent on the Ford 9-inch rear end.  Every run produced a mist of gear lube over the rear deck lid and below.  We then ran a hose off the vent up to near the top of the trunk area with a similar K&M filter like Mike mentioned.  We figured that if a lot ran up there, most would run back down.  Seems to have worked for 15 years.

Well well, another year at the salt. It would be nice to tell you all things went great, but we are going to be working to repair body damage from this seasons course conditions.

It does appear we have solved the engines electrical issues we dealt with over the last two years. The power was there (even if we couldn't use it) & drive-ability was exactly what the driver wanted. Unfortunately, getting sideways at upwards of 230 MPH is not good for certain body parts, like the engine cover. Also, trying to clear the course to not hold up the event is not good for the nose. So I guess we will dig in & repair the body, probably better than repairing engine or drive line damage.   
We will also be looking at adding more weight, why not...

Mike,
     We had the same experience at 150 mph in the street roadster. No traction (15 to 20 MPH tire slip). Spun it twice, ripped up the bottom of the duce shell, some of it from the off course crunchies, some from the 6 inch potholes on the road from the pits to the short course. Saturday we had MUD on the car from towing to the short course, it was miserable. We need about 500 lbs of weight to run in those conditions, a big difference from 2009-10 when it was smooth and dry.

Well, the board seemed a little slow lately & I haven't posted anything here in over a year so?
Here are some of the updates on the race car. We added tail feathers thanks to Bob Dalton & Kirk Harkins. We were going to add more weight but I didn't think the trailer could take it!  muutt  We also had Kevin Elliott at Kev's Rod & Custom fix our nose damage from 2017 (see pictures above) while Mike Kilger at Kilger's Kustom Metal hammered out a super nice engine bubble. We also went back to the chassis dyno after building a new hybrid turbo to do some fine tuning with the magic keyboard. Then it was off to Bonneville 2019.
There is an old saying, we came, we saw, & we put it back in the trailer. Okay, I could have changed it up a bit but the fact remains, we chose not to attempt a pass. As racers we wanted to try & herd our hot rod down the salt, I mean that's what were there for. But after the damage done in 2017 & the obvious issues with the race surface we decided to put it away & hope for better salt in 2020.
We still managed a pretty good "To Do" list for this season because race cars are never truly done. Anyway, here's hoping for good salt!

Thanks Mike... confirms my belief that forward vision is way overrated... although I see that you can see around the tall part a little...
very nice car  :cheers:
