I'm actually running the smallest pulley I can and still safely hit 7500 without over revving the S/C compressor. I'm running a custom 2.5 pulley. I'm actually pretty sure I'm outflowing the current cooler which is rated at 500 CFM's because I swapped the 2.83 to the 2.5 and didn't see an increase in boost as I'm still maxing at 10-11.
The cutoff is 6750 set by the MSD ignition due to my Maf running out of voltage around 6850 and setting off a lean spike that we found at SZ last year. I've got a 90 MM SCT MAF, 700 CFM cooler core, and reworked intake pipe ready to go for this thing. Any guesstimates?
