convering rear wheel kw to fly wheel kw

[Viper_r32]

hey Guy's, put my car on the Dino the other day down at evo in fyswick just to see how much power my pritty stock r32gts-t put out. i got a reading of 137.4 kw at the rear wheel's wich is about 185 bhp. I was just whanted to know if any one can tell me what that is a the fly wheel, as stock its suposed to be 160kW @ 6400rpm (214 bhp) and just whanted to know how much more power mines got from stock!

Thanks

some say theres as much as 20% loss through the g/box, diff etc, but it all depends on the types of g/box, diff. there was a thread about drivetrain losses in another section a little while ago, cant remember where it was though.

what mods have you got?

It's hard working it out in reverse as a %.

I think the expected losses are about 50kw for a manual rwd R33 gts-t, and around 60-65kw for a manual 4wd (GTS-4 or GTR). Higher again if you've got an auto transmission.

So a manual R33 GTS-t at ~180kw at the motor comes down to ~130kw at the rear wheels.

Remember that your motor generally won't be putting out what the factory spec's are due to the age/wear etc..

For an accurate measurement, pull the engine out and wack it on an Engine dyno

I think you're a little generous about 20% loss, I would say 30% and about 50-65% for 4WD (two diffs, well three actually but the centre one doesn't lose as much)

Just my opinion/experiene with kwatw and kwatfw

[PhantomS14]

yeah I would have said around a 1/3rd. Marks on the mark there I think (no pun intended )

[Stirlo_GTR]

so my 233.8 @ wheels would be approx 300 at the engine....

I just heard 20% loss, but the loss is different for different clutches, diff, g/box etc... as Jay said, its hard to figure out a percent
