Ok this is what I have, 6.2L LSA. I have a LSA blower for it and thats the easy part. Here is the hard part, I have to run a LS9 snout due to the fact I need to run the LS9 accessories in my frame set up.

This is where I run into confusion. I'd like to be in the area of 13 psi, which should put me in the area of 700hp with a ported blower and cam. How do I calculate my boost pressures based off this? I tried online calculators and they are all over the place in terms of numbers when just checking the stock numbers.

LSA stock pulley sizes 7.8" balancer 2.95" upper pulley = 9psi of boost.

LS9 stock size balancer is what I want to run and it is 7.33"

All are with a 6700 crankshaft RPM
Stock LSA upper pulley speed is 17,715 RPM.

7.33" balancer
2.6" pulley blower speed is 18,888 RPM.
2.35 Pullet blower speed is 20,898 RPM.
2.25 pulley blower speed is 21,827 RPM.
2.2" pulley blower speed is 22,323 RPM.

Max safe RPM for a LSA blower is 23,000 RPM.
