Wheeler Racing 2011 Quest for 200 MPH
« on: February 11, 2011, 09:57:05 AM »
A great friend and mechanical genius, Jim Bartlett in Portland has developed what may be the first H-D drive train mounted on a bed of rubber isolators. Were running all late model Busa suspension from the handle bars down in the front, with the same Busa rear wheel set.
Gathering parts and pieces with a target date for completion by early May with a street ridden, rubber mounted Hardtail frame. 
Drive train will consist of a 2004 Dyna twin cam 124" Turbo charged motor that is being transplanted from my 2004 that currently has over 160,000 roadworthy miles on the chassis and nearly 4,000 flawless miles on the Turbo set up since early Dec. The 5 Speed is being replaced with a fresh FLT 5 speed.
Please stay tuned for further up dates, were haulin ass with this project.

H-D's have had rubber mounted engines for years, so can you explain how this "bed of rubber isolators" will benefit you?

Good luck with the project! :cheers:

That belt drive primary is probably taking 5-10 mph top speed from you as it sticks out a good 3 inches more than a stock primary.

Harley has rubber mounted units, but not in a hardtail ???  to my knowledge.
Goal is get in it, not on it and have a solid foundation that will not transfer vibration to the pegs, bars and my ass, street and highway friendly as well as Bonneville ready.
We'll see what develops.
Thanks......

Haha! My reading comprehension went away again- I missed the whole hard tailed bit.

Anyway, good luck!

Will this bike be faired or unfaired?

Do you have an idea of how much power it will take in either case? It's easy to underestimate the power needed for 200mph if you have no experience at this. It takes more than you might think. If you don't know, you should ask.

If you have a rough idea, the next question is whether the motor is capable of making that much power, and can it do it for miles at a time, over and over? Sure with a turbo you can get a lot of power out of the motor but will it survive? The cranks are a real trouble spot on these motors. Managing the heat and making the pistons live is another big challenge.

124ci is just over the 2000cc class limit, so it's not the greatest choice in sizes right there. You ought to either go smaller and make the 2000cc class or go bigger to make more power.

There's a reason that HD rubber mounts have their swingarms attached to the motor/trans assembly. By rubber mounting the motor independently of the rear wheel you're going to get big changes in the final drive tension as the motor moves around. Have you thought about how to solve that problem?

Good luck.

This is a hard tail application....with a common motor/transmission bed that is mounted on rubber isolators.

The motor has over 130,000 miles on the lower end and fresh CP turbo pistons @ 8.1.1. Since installing the turbo the motor has over 70 hours running time without a hiccup.

The motor has made 8 passes on the salt, pre-turbo, 2 with turbo set up in 2010.

A fairing is being discussed. Suspension will be all Busa.

thanks for the interest and the input.

Yes, I gathered that, hence my question about how to manage the final drive tension. I'm not saying it's an unsolvable problem, just wondering if you've got a solution.

Being a 124 you probably have some kind of an aftermarket flywheel assembly. Most of those motors are 4.125 bore x 4.625 stroke although some people do them 4.250 bore x 4.375 stroke which could be done on a stock 07-later crank. Hopefully you've got good rods because a rod failure is ugly. With that many miles though I'd be concerned about fatigue regardless.

Have you looked at the pinion runout? Is it staying straight for you? It's a big challenge at the power levels it takes to go 200.

and fresh CP turbo pistons @ 8.1.1.

Since the pushrod motor is rpm limited your only option for making more power is to increase torque and the only way to do that without making the motor bigger is to increase cylinder pressure and that eats pistons. CP makes a fine piston but when cylinder pressures get too high it doesn't really matter much who's piston you have the aluminum melts.

Turbos are popular in LSR because it helps solve this problem by letting you cool the charge after some of the compression is done but before you put it into the motor. Do you have an intercooler? That's going to be really important at this power level.

Yabbut I'd be real cautious about reading that as a good sign for LSR. You'll need to make 200+ horsepower for miles at a time. It's a whole different deal.

How fast did it run with the turbo? How much power was it making?

Great well thought out questions.
The final drive will have with minimal movement since it's mounted on an isolator bed. we hope.....
Lower end is an S&S that's true as ever and well within specs, as of 3,500 miles ago when turbo pistons were installed. The lower end was build by Randy Torgenson in Des Moines, Randy has built a few motors over the years for me, all have been nearly perfect. Were running 4 1/8 pistons.
Set up the turbo with an 8# spring, had Bell inter cooler build an inter cooler designed for the turbo's maximum output.
On the first and only dyno pull thus far, with a slipping clutch (since then freshened up plus a Rivera lock up unit) we made over 170 hp @ 5,000...we attempted a touch more throttle and the bike nearly doubled the forks and tried to escape the dyno's restraints.
May make the Mojave Mile on the new set up, time will tell....possibly not.....BUB for sure....

Rolled to Long Beach yesterday evening and returned home today with late model Busa suspension for the build, front to rear. Next stop is the frame shop in Northern Oregon..

The last post says "late model busa suspension front to rear."  That swingarm rear end is a very good idea for a 200 mph bike.  Please post a few photos of the bike during the build.  I want to see how you mate everything up.  This is an interesting concept.

Figure you're going to need around 200hp if you have a decent fairing and 230+ if you're naked.

Best of luck.

Racer, if you do use partial streamlining, it pays to use it from the beginning.  It takes some time to figure out how to get it to work.  The obvious reward is more speed with less power.  Two other benefits are it keeps most of the salt off of the bike and it is much more comfortable when a person is tucked down out of the wind behind a fairing.

230+ hp naked is being very optimistic to go 200 mph.
