so im picking up another v6 car, and i want to do somethign a lil different on this one instead of another turbo car.

looking around on ebay it seems i can pickup a used supercharger headunit fairly cheap, i know of somone who used a p600b on a 3.8L v6 before. so i went and looked up the specs between the d1 and 600b.

besides the oil supply with the 600b vs the d1 being self contained which one would better be suited to a v6

ive never done a centrifical sc before.

but i do know that i would set the motor up close to my turbo motor specs
8.5-1 cr
272/272 cam on 112 or 114 lsa
ported heads/intake
would spin the motor just a touch over 7k again

i figure max boost of around 18-21 psi at redline

 

i really dont thing your going to get 18-21lb out of a p600b

 

Potentially you should be able to get that much boost out of a P600B due to the smaller displacement of the 6 cyl 189 cubes. You will have to run the smallest blower pulley available from procharger though.

If it was on an 8 cyl, doubtful you could get that much boost.

It more so comes down to how much CFM of air you move that make the power, not how much pressure you stack up in the intake manifold though.
