I recently had my blower ported by magnum powers. I yet to install it I was wondering what you air charge tempeture has decreased to since you have had it ported? How much did you see the boost presure go up? I am only turning the blower 15100 rpm using a 6.5 inch harmonic ballancer and a 2.52 inch blower pullie. I have recently added a 75 mm throttlebody to replace the 70 mm unit. The inside of the plenium was 68 mm and it was opened up to 76 mm.
