boost/pulley change right now im running a vette style D1SC(2000-2004) using an ATI 8 rib bal., stock dia., and a 4 1/4" drive pulley, and a 3 core intercooler-i think below the carb i was running 9.6 lbs boost-i have a 4" pulley, was wondering how much boost i might pick up-i am at 22 degs total timing now, plugs looked good, using a map sensor
i am gonna try and get on Pass Time, was thinking of switching pulleys, but i wont have time to make a pratice pass, would have to hope i hit it right on jetting, maybe switch to #7 plugs
prob safer to stay with a known setup, but would like to kick it up a notch
have you guys seen much diff in tune up on the small pulley change?
