"We just completed the install on a 03 S2000 honda. I was supposed to have nate at rev film it for a segment but got kinda buisy and forgot to call. It is a sweet kit, vortech unit pushing 8 lbs thru the 11-1 comp. engine. Automatic timing retard etc. Nice! we put a HKS exhaust, Toda Billet lightened flywheel, ACT kevlar clutch, And last but not least we will have a wet shot NOS setup at 75 - 100 shot. car should produce 420-440 hp at the crank. We will have it up at the track in the weeks to come. Owner is Al *****, owner of that Black Cobra with the supercharger."

This is a statement from a post that I cut and paste from a local forum that I post at. Does anyone agree with the tuners of this S2000? Seems pretty high to me.

 

What percentage would be appropriate to calculate drivetrain loss? 12%? 10%?

Nobody talks crank horsepower, we like rwhp.

For a FR car 20%
FF, RR, MR 15%
4WD 25%

 

Do you have any S2000 specific information? I've heard estimates of 9% and 10% for the S2000.

Whats, the difference between MR and RR

 

Oh and it sounds about right. 240+100(SC)+100(NAWWWZZZ)=440(I would lean towards the 420 just to allow for losses here or there. I would say maybe 380-400 WHP

20% is too high.

you think so.... i think not. s2000 are rated at 240 hp at the flywheel. if it did theoretically lose 20% to the wheels, it should do 200 flat hp to the wheels. how many s2k's have you seen laying down 200+ bone stock to the wheels? more like 195 whp.

you'll see a loss of 20% accelerating a giant mass type dyno like a dynojet.

Point being, it's useless to say such and such platform loses this much % of power through the drivetrain b/c there are different ways to measure that loss via dyna pack, dyno dynamics, dyno jet, mustand dyno...etc etc etc.

 

I'd like to this....
He has no indication of any stand alone tuning.... good luck....
Beroz

Yes, this will be interesting. Hope he is over compensating for fuel with his NOS setup.

Where the engine is in relevance to the suspension towers. Either way, both have no prop shaft, so just gearbox losses.

 

I'll keep you updated on whp...
