I just changed my blower pulley from the comptech 3-5/8" to a custom made 3" now I need to find other ways to reduce belt slippage. At first i went from 7to 8 PSI to about 4 PSI than i started to tighten up the belt and got it up to 10 PSI. can i over tighen the belt? I currently do not have as much belt wrap as the comptech due to my intercooler. would this make that much of a diffrence? My blower is a 813CFM per rev unit or a 2.3L my goal is about 15 to 16 PSI. I was thinking of building a custom pulley plate that will run everything but the blower and then running a COG style just to the blower from the crank. I guess the biggest down side to supercharging is the oil system being in the way limiting the size of the lower pulley. Has anyone changed out this set up giving more room for the pulley's?
