depending on your pulley size, and overall setup will determine how hard the blower spins.
your f1-a is a 74,000 rpm blower.
another key factor is RPM. Even with a 3.4 blower pulley on my car I will have to raise the rpm to 6700 to get the D1SC to spin 62,000.
The formula goes like this.
To determine the impeller speed, the following formula is used:
Maximum impeller speed = crankshaft pulley diameter (N1) divided by supercharger pulley diameter (N2),multiplied by the step-up ratio (4.10 for the P-series/D series - 5.40 for the F series), multiplied by engine rpm at redline.
blower pulley divided by supercharger pulley times step up times rpm
7.65 / 3.4 = 2.25 times 4.10 = 9.25 times 6700 RPM = 61,807.5
thank bob for that info.

It's getting a snow stage 2 meth kit and run on 93 pump gas also it's 8rib kit with aster bracket so it shouldn't have belt slip but josh said were gunna start out with a 15psi setup he thinks it'll make around 800rwhp

Yeah 1/2 head studs main studs
Callie's dragonslayer crank diamond pistons 9.5-1
Ls9 gaskets with ported 317 heads
I'd love to do e85 but nowhere to buy around here
Josh and Erik said I shouldn't have belt slip with aster bracket but that was when talking about 15-18 lb range but 8-900 rwhp is gunna be crazy
