turbo hayabusa chain drive?

[DanJR1]

Could you use a chain final drive (like a radical) for a Hayabusa turbo engine (350+bhp)? i was thinkin i cud use dragster bike chains (each one has limit of over 500bhp)maybe two of them?it would be for a road legal rally buggy type vechile that could run anywhere. would it be reliable?:confused:

I thick if they are designed to take 500bhp each it should be ok in my humble opinion. Make sure you check the suspension travel does not stretch the chains when at full travel. We have a quad bike that eats chains because of the suspension travel. It sound like it will be seriously quick have fun

Sorry about the spelings I have a few beers :P

Quaife do a chain driven diff with integral reverse gear for bike (almost certainly hyabusa) engines.

I am not sure but i think that bike engines for cars are beefed up a bit but a standard one should work ok...

If you have a copy of the Blue Book, there is a bike tuning company listed in the directory that a couple of bike engined rally cars deal with...

Some big bikes use large belts,I don't know how applicable it is to you project but it may be worth a look as they don't need lubrication and thus are cleaner as well.I am not sure if they are toothed or not but I imagine that they are like a big gilmore belt?? they are pretty wide but quiet also.

Speak with a company called TTS. They are Hayabusa / bike engine specialists and would no doubt be able to help out. I would guess that a drag bike type of chain would be fine. Remember that it is the torque (and hence the tensile force) in the chain that will ultimatley break it and that is a function of how much grip you can put down.

I would have thought to get a Hayabusa motor to 320hp was doing quite wll. I know of one article I saw where the rear wheel horses were 165, which is about what the motor produces at flywheel stock.....but anyway, if you've got one that will do that. I much prefer chains to belts, you see how wide a belt needs to be on a hog to transmit the power (yes they are toothed) they produce. I would suggest to cope with the sort of power you're talking about they would need to be from some very expensive material. I have heard of some hillclimbers using the chains from drag bikes, but they are not ideal, apparently they stretch fairly quickly and you have to life them to a couple of events only. Remember if a chain snaps, you might not just lose drive, but a large chunk of bodywork or worse still, motor casing. I've seen it happen when the chain tries to go round the countershaft sprocket twice.
Take care of the chain, ie wash and lube it each event and I think it will be the best way round it.
Unless you can fit maybe a duplex or triplex industrial chain, thinking out loud here....anyone else ??

Does the SR3 turbo use a chain drive? what i was thinkin is i cud use 3 chains and sprokets to go from the gearbox to the diff. the chains would come from superbikes which usually have around 160bhp plus so 3 would be able to theoreticaly 480bhp.

You could use a geared drive like the DJ Hillclimb Single Seater as a possibility?!?
