When running the SD-concepts spring tentioner and there 7.25 crank pully, what blower pullies make what boost

I hear the 3.7" makes around 12 psi

I have a 3.4" but with 9.3 to one compression and pump gas and methanol injection , i dont want to lift the heads

I hear 14-15 PSI is safe max boost with a good tune and on pump+meth

Please let me know what blower pully you are running and at what boost
thanks
Happy New Year

Depends on the motor combo, how much boost it will make. Whats your motor setup? I am sure someone on here has something pretty close.

What RPM you running it up too, that way we can see how hard the blower is working with the given pulley setup. Shifting around 6300-6500???
At 6500 your spinning it 52,219 blower rpms out of the 62,000
