crazyhorse88, A 3.75" pulley on the supercharger will gain 2psi and should put you at 8psi. The air temperature should still be ok but you need enough fuel volumn to keep up. I don't remember your fuel pump size but a 255lph will be ok or if you have a 190lph or smaller get a secondary pump but dropping the tank and installing the 255lph is much cheaper. Just make sure you change your fluid every 3000 miles and if you do to the track I always change my fluid when I am done or every 1500 miles. Type 'F' is cheap so change often and you will keep the small internal shaft alive for a long time.
