What is stock hp for 2009, 370z?

Those are good numbers dude. Stock HP is 332 at the crank, where the initial power comes from. But some of it is lost through the drivetrain, so WHP are the "real" numbers. Because some drivetrains are better than others, WHP is the best way to measure power output.

I don't mean to hurt your feelings but it seems you lack some basic knowledge. And I can't help but imagine you paid too much for basic exhaust mods. I'm not knocking your exhaust choice, I'm sure its great. But you seem a little naive to me, so I only want to help you. You could have gotten to 316HP with a lot less money. I mean that with the utmost respect.
