Default boost calculations.

forgive me, i used to have this all written down. i dont know where it is.

if u have the formulas, please tell me.

on my procharger D1sc setup, crank pulley is 7.250 and blower pulley is 3.70.
what would my boost be around 6,000rpm, and then 6,500rpm.
now what would it be with a blower pulley that is 3.40?
i know the cam might be a factor in bleed off but in general, what are we talkin?
