so for fun sake, lets just say for ducks, that everything was just a little bit bigger than this setup, like say you had a forged 6.4, a D1 procharger vs. the P1, you were doing 13-14psi vs. the 10, and you have a fuel system to support it.....any guesses as to the rwhp made? Just in theory....:)

737.83 to 758.92

what's a solid guess on psi on the d1 keeping it in it's max efficient rpm? I think Brad was saying he's got the 12lb pulley and I assume that's rated with a stock dampner, and we're looking to use a ati overdrive pulley, just not sure which %

925hp is the capability of the D1SC. Regardless of what the boost level is, expect 900hp or 738rwhp. That might be 10psi, it might be 15psi. Dont look at boost as the indicator of hp. Boost is backpressure plain and simple. If you put a larger cam in a boosted car, it will drop in boost because more of the same air is getting into the combustion chamber and not being stored in the manifold. You end up with less boost, but more hp.

x2. That is something I have learned over the past several months. 10psi on one blower does not always = 10psi on another. If the charge temps are higher, you will have less density of oxygen being forced in which leads to less power. But the backpressure (boost) is the same.

Also, a centri blower in general leads to lower combustion chamber temps because the ability to dissipate heat is also related to rpm, specifically the dwell time of the piston. The higher the rpm the more heat you can dissipate. Since a centri makes boost in relation to rpm you are less likely to detonate at lower rpms compared to a pd blower.
