pulleying Prochargers

ok, so i may be over thinking all this but.....here it is

currently my set up is for a maxed out P1sc, but i am thinking about getting a F1-A so i have room to "grow" down the road

A P1sc Maxes 1200CFM @ 62,000RPM
A F1-A Maxes 1575CFM @ 74,000RPM

equation is; Crank pulley / Blower Pulley X Blower Ratio X Engine RPM

so for a F1-A, 7.65 Crank / 5.25 Blowe X 5.40 X 6200 = 48,785RPM

48785/74000=65%

so 65% of a F1-A would put me at 1,023 CFM

is my though process correct?

No idea...lol. just call procharger.

Run the F1A at current setup and wastegate the cold side.

All teh low end boost

Pretty sure your math is correct

Based off the numbers you put up in the equation, you're actually gonna be at 1038 CFM (rounding down the .33). That puts you at 65.9% of max.

Just do it man... f1a for 2500 sounds like a deal to me...
