Welcome to the DYNOTHON, 2014!
Once again, I’m challenging ALL of you to –
A – Join in the fun.
B – Help us raise some funds for this website.
Just like last year, I’m challenging you all to make a commitment to support this site with a donation. The donation will be based on the BEST HORSEPOWER PULL WE CAN GET OUT OF MY 999 CC, 5 PORT, CARBURETTED, NORMALLY ASPIRATED, 3-MAIN BMC A-SERIES ENGINE.
Last year, we pulled 95.1 hp out of it on T&T's Superflow dynamometer in Gurnee, Illinois. So this year, we do have a baseline, rather than just a decent educated guess.
This year's improvements include -
Paul Ivey racing valves, which demonstrated a measurable increase in exhaust flow on the flow bench.
Coated pistons.
A more stable, adjustable timing belt arrangement, replacing the chain drive. We didn't have time to adjust cam timing last year - this year, we'll see if there is power to be found there.
A new Maniflow all-out race header, comparing it to the Winners Circle unit that helped propel the Pommy Pygmy to 118.693.
A crank scraper and windage tray.
An electric water pump.
A plan that will let me put together a couple of different ignition curves into the brainbox.
A willingness to test a little leaner than last year.
It's my hope we'll see an additional 4.9 hp over last year. A nice 100 hp figure would be the target, but rest assured, we won't walk away without the best possible number.
I can't yet set a date. I'm waiting for rod bolts to arrive, and Fordboy has some early June scheduling things to deal with, but I need to push to have this ready to go no later than June 24th. I'll be finishing up the details necessary to set the appointment, and I will post the date here.
A photograph of the test results will be posted here as proof.
Once again, I'll kick it off with a commitment of $1.00 per horsepower.
No contribution will be considered too small, and if you’d rather not make your generosity public, simply PM Slim the amount you want donate per horsepower, and he’ll maintain your anonymity.
Let’s keep this site financially healthy, and have some fun doing it.
Thank you in advance for your generous participation!
PS - This is the year to participate, because as I start plans for the new DOHC, 4 valve MG/Rover K engine, rest assured, it'll never be cheaper.
For either you OR me . . . :roll:
Ante up! :cheers:

I am in for $15.00 per Hp over last years base, plus a BONUS of $1.00 per tenth hp over 100 hp

Hmmmm . . . Fordboy, how lean can we go and still have a motor for Bonneville?
I'd like to fleece Sparky on this one! :evil:
Thanks, Sparky! :cheers:
-
I'm not as rich as Sparky but I'll go for $5 per HP. By what you described for changes, I'm hoping you see 105.
-
Okay - the die is cast!
I talked with Fordboy this morning, and just got off the phone with Tom at T&T, and the 2nd occasional Dynothon will take place JULY 9 and 10.
https://www.facebook.com/tntracingengines
It's our intention to suck your wallets dry in support of landracing.com.
-
Good luck. We all need to support SSS to help him keep LR online :cheers:
-
Hi Chris,
I'll go $1 per pommy pigmy Hp and I want to be giving over $100 this year....OK!
Cheers :cheers:

American dollars, right Graham?
No discounts for living in paradise. :cheers:
Thanks, Graham!
-
Yep, good ole US Greenbacks! :-D
Paradise is a bit on the chilly side at the moment, well compared to summer anyway!
Your thread is well worth it for the entertainment value alone! :mrgreen:
-
OKAY -
Now that the Aussies and the Americans are out of the World Cup -
DYNOTHON BEGINS WEDNESDAY!
We're shooting for 100 hp on the tractor motor, and Slim needs money to keep this site open.
Some of you have already pledged - thank you - but Wednesday and Thursday, July 9 and 10, we'll be generating the wallet draining numbers (your wallets) that keep this site alive.
Man up - pony up.
Chris
-
Okay - I THINK I'm good to go . . .
First off - Don - I just got your text. I've blocked out 2 days for this one, but I'm going to be scrambling on Wednesday - give me a call Wednesday night - you're more than welcome to ride down and join us on Thursday.
Since June 23rd, I have not had a full day off from work. As a result, on the 5 days when I was only required to work an 8 hour shift, I busted my hump getting the lump ready to go on my off hours.
I don't like to work like this. I'm a bit keyed up, short slept and irritable. The thrash is something I prefer to avoid.
Nevertheless, I'm cautiously confident that we're ready to dyno.
The Dodge is loaded, I'm going to recheck the checklist before I nap out, and tomorrow, I'll stop in Wind Lake, pick up a pale of gas and head down to T&T.
So this is the LAST CALL - I know I can count on a number of you to pony up to keep the site going, but to those of you on the fence, this is the time to make a commitment to landracing.com .
In May, I committed to a buck a horse. I'm raising that to $2.00 and I call.
Are you in, or out? :evil:
-
All the best Chris, you deserve it!
Will Dr Fordboy be in attendance?
Good luck! :cheers:
-
I like Sparky's thinking so I am in for $15.00 for ever hp over 95 and a buck for every .1 over 100.

Chris,
$100 plus 10cents per 0.1 BHP over the ton :-D

Okay - quick report.
Mark and I arrived at 9, and got right on it. It was a slow go - had to fabricate a pair of motor mount brackets - the ones we used last year were left in the car - which is at the paint shop.
We set about setting up the ignition, carb, manifold, primed the pump, installed the header, oil temp sender, the whole laundry list. By 12:30, we took lunch, and got back at it about 1:15.
Mark went about setting up the carb linkage, re jetted the carb to Illinois altitude, and I put together a preliminary advance curve map and downloaded it.
After spilling about a quart of gas from the fuel line - it had been set up for dual carbs on the engine before us - we finally got it started and running by about 3:30.
Mark says he thought it sounded good - we put a load on it and ran it for about 20 minutes to bed the rings in - but we 've got a leak under the front cover. I pulled the cover, and the cam belt was drenched.
It doesn't leak enough to stop us from testing, but we're heading in early to see if we can get that fixed. If not, we'll just top it off, dial up what we can, and I'll fix it when we get home.
I checked the valves - a few tightened up on the exhaust on a hot check - about what you'd expect - but everything else was within a thou or so. I'll redial it in the morning.
No numbers yet. Stay posted . . .
Mark - pick you up at 7:00.
-
Unofficial results - Fordboy will be posting the exact numbers to base your contributions on - BUT -
After reeling in a major oil leak - brought about by nothing short of my misunderstanding of how seals are supposed to work - hey, I'm still a student - and a three hour round trip from Gurnee, Illinois to Cicero Avenue on Chicago's South Side in order to get seals that actually lived up to their title, it appears as though I've got a 99.1 hp motor.
That elusive number - 100 - just isn't going to happen. But we do have a 4.2% increase. On an engine that was compromised by antiquated design parameters the day the ink dried on the blueprints, I'm calling this year's work a success.
Once Fordboy has the sheets sorted and indexed, he will be posting up the numbers here and on the Milwaukee Midget build diary. None of this is proprietary info, and I'm willing to share any sheets we've created in association with this build, so don't hesitate to ask.
Here's a photo of this year's curve along with last year's . . .
(http://i361.photobucket.com/albums/oo58/milwaukeemidget/970%20Spec/DSCN5431_zps5e537541.jpg) (http://s361.photobucket.com/user/milwaukeemidget/media/970%20Spec/DSCN5431_zps5e537541.jpg.html)
We're up on torque across the board, and that 7100 rpm dip that was just so difficult to pull out of has been fixed. Last year, it was all I could do to get the Midget up to a competitive speed by the 2 mile marker. It was still accelerating, although very slowly, between the 2 and the 3. While this graph doesn't show it, there is substantially more power in the 6500-7000 range. This should make the car more driveable, and hopefully take the Midget to terminal velocity quicker. Then, just hold, take a deep breath, relax, and let it cruise until the three.
In short, it will need to be driven like a 3 mile drag car, and it will be a lot easier to do that this year.
Just a huge "thank you" to all who will be making contributions based on these results. This site is a resource for the LSR community that would be sorely missed, and your contributions keep it going.
SEE YOU ON THE SALT! :cheers:
-
Chris & Fordboy, a most valiant effort! :cheers: :cheers:
If we could apply inflation to your lump then you made about 312 HP! :-o:-D
But I'm in for 4.2% x $10 = $42!! :-D
-
Thanks, Woody!
Just posted up some preliminary thoughts on the build diary.
I think the engine is as ready as it will ever be.
And I'm pleased I didn't have to bring it home in a wheelbarrow. :cheers:
-
Good solid results Chris and Mark I'm impressed!
This plus the Aero mods must surely take you to where you want to be! :cheers:
Donation PAID!! :-D

Great! Congratulations, Chris! :cheers:

Money is winging its way electronically to Slim.
Well done, the graph looks good :-D

Neil, I just did the same, and Woody, thanks for your support, both of the website, and your shared insights and thoughts on this project.
And if anybody knows of someone running a vintage Formula Junior car, and is in need of a pretty stout BMC 1 liter 5-port, the Grenade is going to be pensioned off after Speedweek to raise funds for the DOHC 4 valve 1 liter MG/Rover that I'll be running in 2016.
Quite honestly, other than a Lotus 7 - which always had better engine options available - I can't think of another application where one would need a 99 hp tractor motor that turns to 9K all day.
-
Well, I'm going to double my initial pledge. Good job Chris. Hope to see you on the salt next month.
Take care.
-
Chris,
Just Paypal(ed) Slim a hundred bucks, $60 for the additional 4.1 hp and the rest just because! Sorry that I won't be there to see the Midget get the record. Best of luck!!

I like Woody's math 4.2 x $15. == $63.00
done done sorry about no ton

I'm posting this list here -- and will put it on the home page of the site, too.
These are at least some of the folks that have sent in $$ for the website in the recent past. Thanks to the Dynothon there are more than enough to make sending a thank you to each and every one of you easy, so please take notice of your name on this list - if you're wondering if your $$ got through to lr.com HQ. Some of the donations were for other stuff, too - be it Salt Talks shirts or just general principles or to pay for stuff that's for sale on the site.

Again -- thanks very much. And again, if you sent and didn't see your acknowledgement here -- get in touch with me and we'll see how I missed it. :-D :-D :cheers: :cheers: :-) :-)

Wow - Thanks to everybody for joining us on the fun.
Slim - I'm glad it's helpful.
It can be unnerving - watching and listening to an engine spool up, applying the water, realizing the loads being put upon it.
But it's also quite gratifying pulling it off the dyno and realizing that you've got a proven, reliable piece that has the potential to crack a record.
I've become a believer in dyno testing before running. I know there are those who have the ability, experience and the talent to put together an engine that will run strong, and that they can dial it in on the salt - but I'm not that guy.
If I lived closer to Utah, I might be. But given the expense of simply participating - hotel, entry fee, fuel - the time and money spent on a dyno is actually cheap insurance to insure time at Bonneville will be spent running the car, and not working on it.
I've already spent 6 years working on it - why screw up a perfectly good vacation in the desert?
Thanks - EVERYBODY - We'll see you in a few weeks!

Well I decided to join the party late, knowing the outcome; $10/hp improvement==$40
Chris, power peak was right at 8000. How does that fit with your gearing? Expect is somewhere in the 275 pages but I don't have the strength to go find it? Sail boat racing today (think we won fleet, 2nd to finish) and is after 500 . :cheers:

It was though I had reverse-engineered the power curve, and hit the bullseye.
It's a 4.22:1 drive with 22" tires, which puts the peak at about 124. What's cool is that we actually upped the bottom end of the peak power arch, so it should pull through the 3 gear, and fall right into the sweet spot.
Yeah - that's what I said last year . . .
But key is going to be taching at least 7800 in 4th at the 2, so the torque will be put to good use. We need to launch it swiftly, stay in the power band - and let the car do the rest.
Thanks for joining the fund drive, and congrats on the sail boat racing finish. :cheers:
IT'S MOJITO TIME!
-
Thanks, Jack, for the donation. I'll get it onto the list on the home page - I hope. But no hoping about my thanking you. I do appreciate your support, and so does Chris. :-D :-D
-
Man, I cannot wait until I start building my car. I can guarantee, there will be a dynothon for that build.
:cheers:

want to borrow my 8.1 'Burb for a push truck we can get you to 96 pretty fast :-D

SPARKY..........It'a a poser unless it's license plate says BURRRRB.
Rest in Peace, Ray.

Don't laugh - Tom Donny in the J/GT SAAB takes a push to 68. He's only running 2 gears. Check out his GPS speedometer -

I suspect the biggest reason is not so much speed as it is durability. The exhaust gas temps on that thing have to be sky high.
I left the 1974 "Bumberettes" on the car if we determine a push is necessary, but I'm thinking the Magnum R/T would have the cajones if I need to do something that radical.
Realistically, though, having driven it last year, I think the Midget can out-accelerate the Dodge from about 30 mph up.
