[QUOTE="ZeroDCX, post: 15594553, member: 91953"] Before the OP was running the 3.6'' pulley and making 12psi @ 5K RPMs. Now w/ the 3.8'' pulley he's making 12psi @ 6.5k RPMs. So CFM per RPM has come down some, shifting his power curve to the right. OP that's why in a previous post I mentioned that you should call Vortech w/ the serial number. I'm thinking this unit has been upgraded to at least an SI-Trim (1150cfm). But even those boost numbers sound high for an SI-Trim. You're almost pushing boost number w/ the stock 3.6'' pulley the older Novi2k's would with their stock 3.5'' pulley (15psi @ redline)... and they push 1400 cfm. An S-Trim pushing 1000cfm should be no where near this. Not even the T-Trim @ 1200cfm should be pushing those numbers w/ a stock pulley. It wouldn't surprise me if you actually had a TI-Trim.
