how much kw does a ITR pulls out at da wheels

any one know how much kw would a type r pull out at da wheels if it has 170kw at da engine, what would be the at the wheel kws,?

if any FWD car has 170kw at the engine , the drivetrain absorbs say 25-30% of the power.
So that would be about 120-125KW ATW.

A stock DC2 ITR puts 141kw to the engine and about 100kw @ the wheels give or take.

Although your formula is sound I personally wouldn't think a dc2r with 120-125kw atw is making 170 at the fly.Just an opinion and welcome proof to prove me wrong...

Are you sure? Because my EF8 pulled 97kW at the wheels and 117kW at the engine and my Accord pulls 117kW and thats 147kW at the engine so a loss of only 30kW

So loosing 50kW with a Type R is a bit sus...

Can't see how a EF8 would only loose 20kW and my CH9 loosing 30kW that a Type R would loose 50kW... Just doesn't make sense

for fwd, the drivetrain loss is more like 15%, give or take.

if only a 15% drivetrain loss for a FWD then a DC2R would be ~120kw atw.

I've heard/read of stock DC5R's pulling ~110. At a guess i would have thought that RWD have more drivetrain loss than a FWD. 110 atw for a DC5R equates to ~25% loss. Maybe RWD's have about ~30% loss. (of course all cars will be slightly different_

20-25% loss is the norm I'm lead to believe. My Euro did 111kw at the wheels with 140 at the fly (auto). RWD is usually around 25-30% and AWD is higher again just over 30%.

Stock ITR is anywhere from 95-103kw on a dyno.

**bennjamin** · 07-03-2007 07:51 PM

yes as I said and others - it "seems" to be "about" 25-30% loss through the transmission. Accuracy is dependent to the dyno reading it - only in comparison to other cars on the same dyno / same day.
