Has anyone dyno'ed a stock G8 GXP yet? I wonder what the stock RWHP & RWTQ will be?

I'm guessing (hoping) around 350 rwhp.

Wow, that's pretty damn good. Mustang dyno's will probably yield a little bit less, huh?
Thanks for the info. Chris :)

Not to bad at all. I'm thinking my GT put down 363WHP and 368WTQ after my mods, I would love to see the GXP with Intake, Header & x-pipe and tune. I'm betting an easy 420-430WHP.

If I ever get my GXP you will see that exact combo.
Vararam
ARH LT headers with catted x-pipe
Custom tune.

Damn, the 6.2 engines sound like even more monsterous than our puny 6.0 liters! Damn!

Mike I think the main difference is the cam. The .2 liters might make a small difference but the cam is probably the major factor.

Okay, that's cool. I didn't think they were that much bigger than the L76 cam. I mean, I know they are more aggressive to some degree.
*sigh* (can't wait for my cam)...... (before stock G8 GXP's start hitting the road)....

So that would be in the 340s rwhp SAE most likely. Was that a manual or auto?
