Are you familiar with the way Nissan underrated the GTR's power levels for years?

Edmund has the WRX trapping at about 98mph. EVO @ 101. 2011 STI @97 and 2008 STI (old generation) at @102. It wouldn't surprirse me if you are right that the new wrx dynos the same as the STI. At the same time, I believe it is more due to the STI not putting down advertised power. If the WRX puts out 300 at the crank, it would trap 99-101.

Makes sense.
This stuff always becomes a mess when you try to sort it out, since there are so many variables. I had my WRX, and STI, and my Z all on the same dyno within minutes of each other. The WRX is rated at 265 at the crank, and it was laying ~250 to the wheels. On the same dyno, the Z was dropping ~265. The STI made about 255, but the curve was significantly peakier, due to the different turbo they run on it. To me, it's more likely the WRX is underrated (especially since you can't really get away with overrating anymore). The cars just trap low for their power levels due to the huge amount of drivetrain loss.

So then according to your dyno Nissan is lieing about 332HP on the Z? They must, that or you lost 67hp from the drivetrain. The rex can pull of such a good 1/4 mile because of the AWD thats all. These guys running low 13's like a Z can do is because there launching the hell out of the things.

I don't doubt you one bit. 265 seems low on the Z, but still within reasons as Nissan usually lose 16-20% from my prior experiences. The 250 seems slightly high as the car just isn't that fast for its power and weight, numbers don't add up. Judging from the trap speed and time, it is probably pulling 230-240, which is still more than the 260 that it is rated for. It is probably in between the 260-300 that hte STI is rated for at the engine.

Regardless, the WRX is not going to beat the Z at the track unless it is raining or snowing. It doesn't handle anywhere as good stock and it is down on power. It is not a bad car, just not at the same level. WRX=The Ultimate Plow Machine

lots of people do track them it seems like though. When I was selling my 06 Evo RS I had a guy call me who wanted to look at it that raced and had a WRX (older model like 02 or 03 I think) he never called back, I think he just wanted to see what the car had. Luckily I sold it online and didn't have a bunch of people wanting to test drive my car.
