Indeed, it does make sense that it's not a percentage. I believe the figure I quoted was probably for "25% on a stock B5 S4", ie, if you're not upgrade from the 265, then you're losing around 25%. If you have upgraded, then it's different, probably as jeffw stated - increases with power output, but not as fast.

Could be wrong, but if your car has a 100bhp transmission loss, and the flywheel Hp is 265 standard. If you up the power on the car say to 500bhp your transmission loss should still be the same?

[jeffw]

You would expect some more losses due to heat and thermal efficency but not much...The only way to be sure would be on an engine dyno.

This is a goer and I think a lot cheaper than those quoted with approx 1/4 the weight of std shaft weight whilst remaining twice as strong.

Looking for doner parts to make moulds/take sizings from.....?

Will this be wet or dry carbon Rob? I'll pm my contact details, could do with a chat to move this forward mate

Cheers,

I know I'm going to regret asking but....ball park figure on price ?

Jeff - for what parts? Propshaft? Less than £1k, not sure how much just now as still trying to price up stuff and need to design and build one and then have it tested to destruction.
