^ you're making 456whp?

455

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.

That should read 12.8 @ 113. 133mph would be insanely fast.

Agreed...but how the hell do they manage to only run high 12's? My Stillen SC 370z in Forza 3 runs mid 11's with slicks and around 520 crank hp :icon14:

Traction probably. I should be running mid 12s but traction, I does not have it. :icon17:

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.

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.

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.

Well on one dyno, anyway.

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

^ 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.
