R34 Gtr Stock: What Awkw?

[Bakes]

What Kw does a stock R34 GTR pull on a rolling dyno at ALL wheels?

Is it ~180AWKW?

Thanks

they came out with 206kw standard

^ wow, possibly the most useless reply ever...

1) 206kw is the "stated" figure, ever noticed how many JDM cars have that as the power figure? heard of the 'gentlemen agreement'? That was the cap

2) GTR would be, i dunno, more 250-260kw at the fly

3) he was after AWKW!!!! not same bogus factory claim fly wheel number!!

to answer your question, i dunno but 180-190awkw sounds about right

Actually no i haven't noticed that. i'll keep an eye out for that from now on tho.

I wasn't trying to make a useless reply. I posted what i thought was right. I obviously wasn't and i accept that.

thanks for all the stuff you put up there tho. i'll keep that in mind

Another question: What boost do they run stock?

Several posts down. One of NZ top tuners dyno tuned his own stock R34.

175kw atw

And if it's correct about the 30% drivetrain loss it's about 227 at the fly

.92 bar i think off memory

30% drive train loss is too low as an AWD setup, or, awkw reading will have more power lost through the drive train than a rwd car would.

there is no way a car weighing around 1600kg, can do what it does with just 227kw's.

250-260kw's or more at the fly would be my guess.

It's basically saying that an extra turbo, extra displacement (plus a whole raft of better components than a NEO RB25DET) only gains 21kw's? Not likely...

Unless you want to rip the engine out and dyno that, you won't know what the factory specs are. Someone may have done this already, i dunno... but yeah, more lost through the AWD than RWD

.92 bar i think off memory

I thought its closer to .9 BAR on 34's and .85 bar on R33's, anyway .92 bar sounds about right

Debatable, there are thread on here that have done a RWD then an AWD dyno and lost 1KW.

Others have noticed big differences but its usually different dyno/different day so its not comparable.

I think the 175AWKW for an R34 sounds about right, when shopping around I'd seen higher than that though for stock R34's.

I read somewhere that a group of Poms pulled an engine out of an R34 GTR and put it on an engine dyno. From memory the engine made approx 240kw at the fly. So anything around 180awkw sounds about right

That sounds pretty spot on. thats what I would expect from it.

I dyno'd a stock one when I was looking to buy mine a few years back and it made 178awkw's - so 175-180 is where they are at.

The funny thing is I know of 2 x NUR's that have been dyno'd stock and both have made under 160awkws..... So much for the ultimate.

Sux to be those guys All that extra money to make less power stock.

I always thought 34 GTR's would make a little more than the above quoted figures....

The r34 GTR I read comes with 327 HP not 280 like they say. That is 243Kw instead of the 206kw stated.

Not sure if this is a useful comparison but a stock AUTO stagea s2 has 206kw at the flywheel (probably accurate in this case) and roughly 120awkw. They also weigh around 1658kg.

So thats a loss of about 86kw. The losses dont increase by much as you increase the power so working by percentage doesn't give an accurate enough result...

At a very rough guess, I'd say make that ~70kw drivetrain loss given the GTR is manual and a bit lighter (AFAIK the GTR's are about 1500kg or thereabouts - feel free to correct me).

I've also heard of them getting around ~180awkw completely stock so that would put it at about 250kw at the flywheel. anything around 240-250kw should be accurate enough in my opinion.

And just for the record, the "Gentlemans agreement" in japan seems to have finally been lifted since we now have cars in japan like the R35 GTR and others smashing the 206kw limit to pieces.
