Bob Dalton here from the 7800 A/BFS
I posted a video... of the last (our 4th long course) run we made MINUS the wing.. (we had a tire rub, oops)
Play it on a big screen computer.. and hold on!
So first gear.. takes it to 300 mph... yea I shift into 2nd at 300 mph
2nd takes me to ... 380mph.. and that was the problem.. shifting into high gear at 380 on the salt we had.
We added even more power for 3rd gear/high (oops again)... and well ... damn driver couldn't hold on to it..
good aero balance though... lol
Traction Control bought to you by.... well the Driver.. ok, no one! :-D :cheers:
enjoy....

Garan turned up the wick a bit?
Wow, what a ride!
-
If Garran had his way.. I would have stayed between the markers.. :cheers:
it was only the 4th pass.. :-D
bob
dodge? hmm
-
Bob when I spun in 1957 1/2 way thru the 5th mile and I saw the starting line going away I knew something was wrong, the next 1/2 of the spin I saw floating mountain again, closed my eyes and waited for it to stop. I was lucky as it was a rear engine modified roadster, several others flipped and the next year they banned them. Bonneville can be tricky for sure. My spin was caused by a broken crank and it locked up the drive train. :-D
-
Wow! You guys were at Speedweek? :-P :evil: 8-)
-
Mike ...
thats good.....
310 mph first mile.... way off .. but so am I
365 mph second mile ... better..
darn last mile..
as an engine builder Mike..
you know the drill
"I need MORE POWER" :-D

Got to meet him and the rest of the hoodlums he hangs with, owe them some beer as a matter of fact ;) I will look you up next year. Trent

Bob......
The times, they are a changing.........
FTG!
PS. Use a dust mask at Pomona........ :-D
-
The movement of the streamliner at speed made me pucker just watching it. The nerve to push the vehicle to higher speeds while the horizon moves back and forth is something else.
You just got attention from here on out!!

There is no doubt that your vertical stabilizer really works!!! That was definitely a "big balls" run!
Rex

Mike ..
I was thinking... How can I go 200 mph with this four banger..
then 300 with a 258 e/bfs
but really in the back of my head...
I was thinking... I really want a Hemi like Al Teague has..
-
WOW!!! That was an awesome run Bob. It's not easy to stay calm under those circumstances and you did a fine job. :cheers: :cheers: :cheers:
Looking forward to future runs. Another really fast streamliner.

Thanks Guys....
the reason for the video...
was I wanted to see how the run went...
after I opened my EYES! :cheers: :cheers: :cheers:
-
Bob, thats nuckin futs :-D
-
What were the runs like with the wing?
-
Really Really Boring...
except for the sidewalls of the tires showing cord.. :-o :-o :-o
first pass to the 5 mile.. 382 out the back.. dead rich
-
The wing might be pushing it down too hard, and no wing not enough. What about a narrower or shorter wing?
-
probably no wing... and good salt.. :roll:
and a better driver..
we probably should find a good turbo engine.. :-D
no really..
I hear you can de-tune them easier.. :cheers:
-
Awesome clip, great car...thanks!
Gary
-
WW,
It will have wheel spacers, wing, and more power! Dalton will be crying for his mama. We are praying for salt like 2012 WF. Right-on Mike LMAO.
POPS
-
:-o :-( :cry: :x :-o :? :cry: :cry: :cry:
-
Thanks for the ride.....
Incredible.............
-
Can't the wing be trimmed out and then downforce dialled in as required. I know with the Indy cars it didn't take very much adjustment to make a significant difference. Changing the wicker could also be used to tune the downforce.
Pete
-
This Pilot brings his' Private Parts ' to the salt in a Wheel Barrow, Wow that was unbelieveable
Almost like driving a Sprint Car at 400!!!!!!
Maybe more lead to keep it planted?
G Don
-
That was a wild ride!
-
WOW !!!
-
Great video, and good looking car! Just curious what modifications had to be made to the car so the drivers balls would fit inside?
-
Really Really Boring... :?
I hope that my new car can be that way for every run
-
1/2 mile fishtails at 350+mph!!!! WOW
-
SPARKY,
Put a wing on it! Your old car moved around a lot as a recall. I will bet you a case of beer that you can't run 400 without one.
POPS
PS, If you guys keep talking about Bobs driving skills his head won't fit in the car.
-
Me and Cook JR were at the 41/2 in the "crash truck" and we saw that you were alittle sideways a few times, but if sounded bitchen coming to us, I know a guy with a turbo motor :-P
-
Sprint car at 395, Great idea ! :-D
I did drive circle track..
This run was driven with my right front... steering like a sprint car. To bad I didn't pedal it again at 395, maybe I'd have a 400 mph time slip.. The point of land racing is to get that ride that will be beyond an E ticket ride. You drivers out there know what I'm talking about. The one run that will be in your memory forever. For me this was just the beginning..
FYI .. for you builders, pay attention to center of mass vs center of pressure. Keeps you pointed in the right direction on bad salt. And IF you are going to put a tail on your car, put it in the wind, away from the body (boundary layer).
Pops.. I ordered a new helmet.. :mrgreen:
This little old Hemi... it may just be fine..
Just need NITRO.. :cheers:
-
The Video's of George's hands on the wheel, looks like he is going to the store for a soda at 400 plus
Sure would like to see a Video of your wheel being worked out
I like your Style of driving ' Gas It Up ' boy that has got to be a Thrill having wheel spin at 400 !!
G Don
-
Hands don't really move much. It was driven by the throttle blade.
And it was only the 4th long course pass .
It will be straighter next time.
I can't really afford to buy new tires every run.
-
With that much HP tires will always be a worry and if tires need to be changed often it will be the least expensive thing you ever did to reach 400+. Funny thing about motorsports something is always reaching in your wallet......Good Luck
-
George who? :wink:
-
WOW great Video...............
-
Hmmm, all right. I just now got around to watching the video, and my reaction was "Hey, he did a LOT of steering!!" It sure looked fun, so to speak, and I do certainly look forward to seeing the car run next year on the salt.
Comment: Downplay the music and let us hear the motor and the gears and that stuff, please. I know that Mr. and Mrs. Sixpack won't likely enjoy the noises -- but I sure as heck do and I know other racers that'd rather hear a hemi than a guitar. I will grant you thanks, though, for having the music be low key and sorta mellow (instead of some of the stuff that I've heard on videos).
-

Bob,
Speaking of throttle blades, who's injector is that, or who made it? I have never seen one quite like it before.
Thanks,

Video from Monday afternoon (small handheld camera). Fiercest sounding streamliner that I heard this year on the salt.
http://youtu.be/WtLYP9nEQUA

Yep i'am with Slim, 86 the rock all together as hearing a blown fueler go for 5 miles is one of the sweetest sounds on earth
I hate music on racing videos because you cant hear the race cars !!!!!!!!
G Don
-
The problem with cameras on the cars, is small tiny mics on small bullet cameras..
what is picked up is all the other sounds.. wind body rattles etc.. not blown hemi..
we need the sound.. which is behind the car.. like this video..
so we are looking for camera people to record the car as is goes down the track..
here is the first on the gas run I made in 20 years.. 322 quarter last fall.
I was to run to the 3 mile per Mr Kennedy.. camera people didn't know
http://www.youtube.com/watch?v=VkXUaOCe7AI
-
A beautiful, impressive car and some great driving. Hope the driving becomes more 'boring' again so the car can be in the throttle almost all of the time. If so you are going to put up some very impressive speeds.
I'd really be interested in any information you'd care to share about the drive train (engine, transmission, rear-end). Any other construction pictures would be great. I looked on you web site but couldn't find any :cry:.
The best of luck,

YEE HAW! And I thought Roadster drivers got all the fun. Kinda like driving a blown forklift on ice huh?

I found while filming the AA/FA I was crewing on a month or so ago that my GoPro ddint pick up nearly as much of the engine noise as it should and it was mounted on the rollcage. Apparently I shouldve put a different back cover on it to pick up more of the noise. Live and learn.
-
Driving with the throttle? Please! Dude, you drove the crap out of that thing! Wild Willy would be proud! Awesome!
-
A good reason we need the black lines on the two long courses.
-
Yes ...Please...Is this something still realistically achievable...?... Ill pay extra...perhaps have long course fee...it does take much more prep and resources...logistically likely not doable...so "redistribute" (share) the cost to put a line down the dang middle of course ...Please...
-
What I heard on the salt was that the black lines used to be motor oil. The blue lines this year were some kind of blueberry biodegradable stuff.
-
Lines might have been a Good Thing...
Did anyone see ALL the lines of oil from ALL those years of racing?
Or did they get pumped AWAY with the salt?
Oil floats on Water doesn't it?
Ponder
-
Yes but. If they were still allowing black lines, I wouldn't have my souvenir piece of the course marker you hit. I may sell that on Ebay.
-
that is funny Rich..
Not sure I'm showing that one.. :-o :-o

Here's a fun tip, take the little rubber gasket out of the GoPro case and you'll pick up engine noise much better. This only works if your camera is mounted inside the car. For hand held cameras, a piece of masking tape over the microphone will help to eliminate wind noise but still allow other sounds to be recorded. That comes in handy at places like Bonneville where the wind always seems to be blowing.
To the OP, Thanks for sharing the footage! Its neat going along for a ride with you fast guys.
-
You generally go in the direction you are looking while driving. The one thing I noticed with the flags is I tried to stay to the side of the course where things weren't chewed up as much and found myself coming closer to the flags a couple times than I wanted to be since I was looking to stay just off of them. Other than that they were fine but I never had a chance to drive with the lines,

Target fixation strikes again. :evil: :evil:

lol oh so true

Yep, I was looking to get off that course..
I kept yelling "Jane get me OFF this Crazy thing" :-o :-o
I figured out the "oil vs markers deal"
I just need to pickup 105 mph.. then the markers will be like a fence.. :cheers:
-
Target fixation strikes again. :evil: :evil:
I'm wondering if target fixation or the possible fear of it happening might of indirectly contributed to the number of spins this year. Most of the comments I heard at SW were blaming a rough track for the spins. Why was it so rough? Maybe because more drivers were driving down the middle of the course?
The flags are easy to use driving down the middle. Your natural reaction is to center yourself on them looking down course. So in that respect they do the job. In years past and for some like myself when the track gets rough drivers search for good salt along the sides. With the lines it feels natural to run right next to them. Think of how much easier it is to run down a narrow rural highway at night that has the lines painted on the road just off the shoulder vs. the same road with no lines and reflectors on posts a few feet off the road.
Trying to run down the course on the sides with the flags is harder and not as natural. You are running over 200 and trying to gauge where you should be off a flag 1/4 mile ahead so that when you get there you will be 10 feet or so off to the side of it. Much harder than running 10 feet off of a line on the salt.
I have a feeling that less drivers were running close to the sides of the track and more towards the middle than in the past. We ran late in the week when the courses were even tore up more and I ran as close to the sides as possible and found that the course really didn't seem that bad and had no problems. Like Joe I'd pay a little more entry fee to have the lines. I think they would give you more options on where you are running vs. the flags,
Sum
-
We ran course two, the starter told us the right side was better than the center so we ran there. Simple really.
-
I still have a salt print on the street in front of my house. from Bob's parts trailer. It's kind of surprising that no one has ever asked me what happened to the street in front. City seems to be interested in everything else that happens.
-
damn Rich.. reminds me .. need to wash trailer.. :roll:
Yea.. I started on the "right side" seemed like a good idea.. car wanted that too.. and the left .. center.. more right.. more right .. whoa.. to much right side..
earlier this year, I was speaking with Harry Hoffman of Markley Hoffman Liner fame.. he mentioned that when you are going real fast .. in this case 380 to 395 .. the course get narrower.. I now understand..
Just as I noticed how far apart the markers are at 55 mph.. not so much at 395.. :cheers:
here are some pics Sum .. from the 80's and early 90's
first year no body.. no money either..
later pic, body.. but still no money..

Nothing as fun as having to cut up your car of 30 years..
Cage was to small.. size and diameter tube .. replaced with 1 3/4 3/16 wall

Comparing new cage shape to old
that is a big rear end..

A few years back, probably the year that they eliminated the line,
Marlo Treit offered to pay the bill for the lines.
They said NO.

then you have to Balance that with a Bigger Engine.. and or Supercharger.. :roll:

"trial runs at the Bonneville salt flats the DMPE supercharged car ran 322.11 mph in the 2 1/4 mile traps. This is the third fastest time in history."
Bob,
Congratulations, that is quite an accomplishment. Is the Hot Rod Trophy next? :cheers:
Is your blower a High Helix type or one of DMPE's special built for Bonneville application.
Thanks for any help,
Tom G.
-
yea well I don't write websites.. :roll:
I think High Helix.. But, Honestly I have no idea..
I do know it runs real good....
So.. the 395 off the track run.. 289mph 1/4 313mph 1st mile 364mph middle mile..
so the 1/4 was 30mph off the World Finals... hmm
-
Can you tell us what this car weighs?

Rob
on that run 3750
Questions.. to ponder Spirit of America first run with no tail, why did he put a tail on later?
Why did Donald Campbell after he crashed at Bonneville add a tail?
Why did the Danny Boy Apple car (a front engine front wheel drive car) add a tail after they crashed?
What is the cd of a Naca 0012 at zero angle of attack? .006? .008? .010?
What is the total drag of a tail with a cd so low?
ponder...
I did say at a Hyatt once.. :cheers:
-
Rob the real question 60% rear .. and about 800hp too much power.. :-D
-
First thanks for all of the pictures. You should think about moving them also to the build section on this site :-).
I noticed front suspension in one. Does the car still have that and yes the rear-end is huge? Is the transmission a lenco?
....
What is the cd of a Naca 0012 at zero angle of attack? .006? .008? .010?
What is the total drag of a tail with a cd so low?
If the tail was say 2 inches thick by 4 foot tall (.666 frontal area) with a Cd of .010 it would take about 5 HP to move it through the air at 500 mph. I think you can handle that :-).
It is pretty easy to figure using the spreadsheet I have here:
http://purplesagetradingpost.com/sumner/bvillecar/bville-spreadsheet-index.html (http://purplesagetradingpost.com/sumner/bvillecar/bville-spreadsheet-index.html)
Use the "HP needed for A Lakester or Car to Run a Certain MPH" one and put in zeros for the tire/wheel data and then where you would put in the body put in the tail alone. You could also use it to figure HP needed for a wing at a certain speed or your car body. Figure the 3 separately and then add them together for total HP needed,
Sum
-
Yea there are springs.. in all four corners
B&J trans
regarding tail... I did stay at the hyatt.. :-D
just trying to stir the mush in peoples heads..
My tail got larger after the backend of my car tried to pass the frontend
That is when I sat down with Robert T Jones by luck.. google him
5 hp hmm.. how much percentage is that of 1400hp? hmm to be safe?
:cheers:
-
5 HP is 0.35% of 1400 HP.
Hard to tune for that .
FREUD

Aircraft designers do drag build ups all the time by adding parts separately. If done correctly, you can expect accuracy within 3%.
Now it is time for you to leave this Cd stuff behind and start talking flat plate drag equivalence. This is a much better measurement
system for figuring out the total force needed to over come drag created when moving a body through the air at a particular speed. This is much more relative to what we are doing.
The correct way to measure aero drag is this formula.
Stagnation drag + Separation Drag + Wetted Area Drag = Total Aero Drag.
The hardest things for us car guys to grasp is that frontal area was not mentioned anywhere in the equation. This is why you could double the width of your tail-fin (if for some reason you wanted to) and it will not double it's drag.
It sound like you are on the right track back not being afraid to drag those tail feathers through the air. Heck we have two giant tail fins on our car at a full 18% of cord.
-
Al Teague tried a small wing on his liner and it slowed it down.
-
Al's wing may have been too close to the body.
Frontal area is often missed by guys building cars. I was impressed by the first small car I saw. Don Debrings liner. And that is what I based my car on. Building the smallest car possible. Jacks Nebulous cars are built on the same concept. There does become a point were packaging any smaller becomes very very difficult. We have our 40 lbs of hemi packed into our 5 lb car.
:cheers:
-
Glen,
There is way more to the story than "went slower with wing",
What supported the wing? Airfoil uprights or round tube with a diagonal brace?
I know that the wing had a 4:1 aspect ratio but I don't know what the airfoil was or the angle of attack? How much did it slow car and at which angle of attack as I know they tried a couple?
Did the car handle any better?
Need more data.
We now live on a different era where a reliable 2500 to 3000 hp engines is common. Not inexpensive, but common. I say, when we can start using it all, we can scale back on the wings and other methods of downforce.
-
More Data: The wing was close to the body, was mounted on vertical aluminum plate. IIRC, Al only made one pass with the wing, was only a couple MPH slower and was on 7 cylinders from the git-go.

Rob,
That the frontal area is not mentioned explicitly in your equation doesn’t mean frontal area has no bearing on the performance. Your second sentence essentially says that drag is independent of the frontal area--which is obviously incorrect.
While a drag coefficient is really a fudge factor allowing useful results to be easily extracted from the characteristics of the shape and fluid properties, your expression is made up of quantities that are very hard to determine.
If you think your equation is so superior, please explain, for example, what “stagnation drag” or “separation drag” is and how to predict it. Can you do so without involving frontal area? (And can you do that for non-streamlined shapes?). Your terms seem like alternate expressions for pressure drag and skin friction.
Al’s wing: Any aero appendage is going to add drag and therefore negatively impact performance unless its effect allows the vehicle to sufficiently overcome a stability and/or traction barrier.
-
This is a great discussion but let's not hijack this thread any further. I will start another thread in the technical discussions. :-)
-

Since there were numerous "haircuts", traction was always a problem.
Ron
-
I take it the reason for removing the wing was tire rub? I'm going to guess that will be fixed and the next run will be with the wing.
With that kind of horsepower and no traction control I would think about modifying the throttle linkage to give you more travel at the last 15% so the control is better.
Having said that, I don't see any reason NOT to run traction control with that kind of horsepower. Trying to keep the slip level within bounds is tricky at best and can quickly get away from you.
-
Yes..
OK. But I believe .. injector is at full flow at 40% open.. it is being changed. I'm thinking 2 hole hilborn. :cheers:
Who makes TC for blown hemis? Surely you would not kill cylinders. :roll:
-
Seems awful dangerous!
-
What is that?
-
Killing cylinders will lift the blower? I see that on NHRA TV all the time.
DW
-
Clutch slip?
-
Pulsing the brakes is the most likely path for traction control in this case.
They also pull timing as a means of controlling power.
But if they choose to drop cylinders I'll gladly watch the show.... :-o
-
That the frontal area is not mentioned explicitly in your equation doesn’t mean frontal area has no bearing on the performance. Your second sentence essentially says that drag is independent of the frontal area--which is obviously incorrect.
I believe in aircraft design parlance the term "drag coefficient" is sometimes used referencing plan view area - the area as viewed from directly above, rather than from the front. This area, which on an airplane is fairly closely proportionate to the total surface area of the craft, is more useful in this context than frontal area as car guys use the term. For very clean forms, friction drag from skin surface is the largest component of drag.
Thinking about a streamliner design without referencing frontal area is a valuable mental exercise because it alerts you to the possibility that your design might be improved by packaging the necessary components in a fatter, shorter form rather than the sausage-like shape of many streamliners. The solid with the lowest surface-to-volume ratio is, after all, the sphere. The long wheelbase desired for stability can be achieved with a super-skinny tube a la Costella's creations.

Or is it Sammy Hagar. .. I can't drive 55
We don't need no stinking traction control

You too mike
Speaking of traction control. if I'm a clutch guy/ homeless guy(G man joke)
I'm sure I will learn something.. no laughing though..
-
Tortoise,
Generally, the LIFT coefficient is referenced to the planform area. Skin friction is collected into the drag coefficient.

Hands don't really move much. It was driven by the throttle blade.
And it was only the 4th long course pass .
It will be straighter next time.
I can't really afford to buy new tires every run.
Would a higher gear calm it down, I know a certain lakester guy who runs the fastest who runs very tall gears, and low rpm
at finish. Never have talked to him about the setup but have a feeling the high gears keeps the hp from overpowering the chassis
and also loads the motor so they can burn more fuel.

You mean those super small frontal area cars he builds.... :roll:
I ain't saying low frontal area is a bad thing, just than the total square inches of skin surface is very significant, which Jack's cars illustrate. Concentrating only on low frontal area might lead you to think that splicing in a cylindrical extension in a belly tank would not increase drag significantly. Not so.

Sorry Bob,
Some of us are committed to El Mirage this weekend, I don't know who plans these things. Didn't happen when I was doing it.
You and Jackson put the thing in the show, OK?

You mean those super small frontal area cars he builds.... :roll:
