nope we are different than the GP in when the motor went into the cars. the series II SC went into the bonne in 96, any 96+ makes around 9-10 in totally stock form

A stock L67 makes 6psi according to GM FOR ANY MODEL. It varies from car to car due to differences between engines from production, but it is usually between 6-8psi. The L67 that goes into the h-bodies is exactly the same as the L67 that goes into the w-bodies except for things they change due to the different platform, like oil pan, coil bracket, etc... A SII L67 SSEi is going to make the same boost as a 97-03 GTP.

boost
I have a 95 ssei, cold air intake highflow cat., 80 series flowmaster, I put an after market boost gauge that i built a pillar pod for pictures somewhere in a forum. With performance shift on i get about 12pds boost at full out off the line, and around 8-9pds of boost in normal shift, I still have the stock pulley but I do have a 2.5 pulley that i will puting on when its gets nice out. Its a series 1 superhcarged engine. I heard that the 92-93 ssei were the fastest? So maybe more out of one those superchargers, smaller pulley was a factory built on a 92-93.

you are a little confused..... the 94/95 make more horsepower than the 92-93 even though the 92-93 had the smaller pulley, most 94-95 guys like finding a 92-93 pulley, or smaller for there cars
