help! cant figure out which pulley to use! Shooting for 8 psi tvs2300...
Stock cam (no overlap)

And longtubes.
The throttle body supposedly adds boost... that is whats throwing me off

more flow less boost.... go by the rpm % of the blower not the boost level. Boost level described amount of restriction. for instance, Crank pulley size/BLower pulley size X (step up ration of Blower) X Max RPM= RPM of blower. My example on my F1X is 7.0/3.75X5.40X7200=72,576 rpm of the blower at 7200 rpm... Now boost level will change depending many other factors.

Power wise i want to match what a stock zr1 can do if its within reason.
Stock valve train, great intake, full exhaust is what I got. What pulley size do i need to make that kind of power with my new tvs 2300? And who sells quality pulley kits for magnachargers?
I wouldn't shoot for a boost number
Lots of different factors will determine psi
Heads/cam/exhaust flow
Air intake/tb/snout
I'd leave the stock pulley on for now and see if youre satisfied with the power
If not dropping .1 in upper pulley size usually increases .5-1 psi
Overdrive crank pulley will usually net 3-4 psi, and can be used with a smaller upper pulley to really spin it
