Can any one here tell me what the stock boost on a Pontiac Grand Prix GTP is? Also how much the stock engine can handle.

stock boost is around 7psi due to cooling issues , but the supercharger maxes out at 14psi. I heard the tranny doesn't hold up well on those cars.

He's a friend of mine who doesn't use the site, but he doesn't have any mods except some extra weight for his subs. Lol.
