I have a 2.3L whipple charger it flows 812 Cfm/Rev and the stock comptech flows 565 Cfm/Rev it is bolted on an modified comptech Intake. I am running the 9lb pulley from comptech and i just installed a boost gage. first reading was 5 lbs so i tighened the belt up and the pulled 9PSI. does this make sence? i would have thought that since the CFM is much higher that the PSI would also be.the gage i just installed is an auto meter and came with a very small line 1/8" or so i had already ran a 1/4" line so i used it would that give a false reading? i will start to tune the car next week but was just wondering if the boost seems correct. i will have a set of pulleys made to reduce the slippage i would like to dial in the dia before have them custom made. also would any one else be insressed in a set of COG pulleys if i have them made it could reduce the costif ordering more than one set.
