Default 600sc drive ratio vs boost

Basically building a pair of intercooled 600sc clones looking for actual hard numbers on what everyones running for pullies and what the psi is with them.

Stock 600sc pulley ratio was .93:1 or basically 7% underdrive. I believe on the 600sc, it made about 5-6psi.

You got the 16 Rib pulleys right ? Teague and blower shop have them in different sizes.
