I'd say 17% is a more accurate measure if your whp was measured on a Dynojet. Stock G37 coupe is rated at 330bhp. Almost every dyno for a stock G37 on a DJ is about 275whp. That's approx 17% loss ( 275whp / 0.83% = 331bhp)

Yes agreed. I'm being more conservative though. You gotta take all these numbers as a general indicator rather than a fact. Too many variables can affect results. So if you want to be more realistic, whenever you come to a conclusion that sounds accurate, subtract out the "ricer math factor" and then subtract some more...after that you might be in the ballpark.

Did the test car in the article run slicks?

I wish Forza would show a full time slip rather than just 1/4m time.

If you go into your setup and hit "Benchmark" it gives you a 0-60 and more info too I think.

Push370zzz

I believe it only gives you 0-60, 0-100, and top speed for the acceleration figures

I think I might go try it out and see how it actually compares to my car.

Q8y_drifter

Make sure you leave the weight stock. My first "mod" for any car in Forza is to fully strip it :P

Just read the Road & Track blurb on Stillen's test mule and they cited the large amount of negative camber in the rear as a factor that hurt off-the-line grip.

So? It got 0-60 a good bit quicker and only managed to drop a touch in the 1/4 and had a very weak trap-speed. No amount of "traction limitation" is going to account for this showing.

Nitex

^^ Am i missing something here? Do you have the Stillen SC kit, and your saying you ran a faster 0-60 but slower 1/4 and trap? Weird... Can someone confirm this?

It trapped 113. I'm guessing that was in SoCal and in the summer. 113 is pretty good. Last summer with bolt-ons, but pre-supercharger, my highest trap was 104 mph. It's also 1/2 second quicker in the quarter mile than what all the car magazines were able to get.

The flip side though, is that in 2004 motortrend tested the z51 c6 corvette and it ran a 12.7 @ 112 with 400 engine hp. That's 115 hp less than what Stillen is claiming from their press car.

ImportConvert

Exactly. The 'vette weighs about the same as a Z, and ran about the same time as the "supposed" 515bhp Z. That Z does NOT! make 515bhp unless the driveline is sucking up 150hp. Sorry. Not happening with those numbers unless they slammed the brakes on at the 1000' mark.

RCZ

^ I was kinda kidding, I know forza physics are good, but they are still a little too "perfect". I guess it would mathematically give you a ideal scenario of weight v power with some form of tire slip. I'll try it out later fwiw.

Lug

People are comparing results from different magazines. I've seen MT get a 4.6 on the 370Z vs. 4.9 from C&D vs. 5.1 from Edmunds & others. That's a 1/2 second swing on the exact same car. This is all before you account for different cars with different traction, etc. You just can't cross-compare like that with any reasonable accuracy.
