[QUOTE]Originally posted by need-a-cage: [QB] Are you talking to me? You know what it is! Anyway, I did the math a while back for the SQ trim and it was maxed out with a 2.95 if I took it over 6k. I need a better fuel system to run any more boost. I was leaning out the night before the races when I was checking out the 3.15 pulley. The AFR would shoot straight up after 5700rpm. It was so much warmer the next day that the motor wasn't getting enough air to lean out but the AFR was a little leaner than my commanded AFR. I did run a 2.95 at Infineon just to see what it would do. I ran it all out to the 1/8th on radials. I then idled through the 60ft and then got on it. It was in the 12's at 126.5mph but it got lean in 4th. The 3.33 is a good pulley for me right now. It gets 12psi in very cold weather and the AFR is steady at 11.5 all the way through the rpm range. With the 3.15, it was in the high 11's and would lean out in the top of 4th in cold weather. Craig [/QB][/QUOTE]
