First run on new motor this year. 93 octane, 15-17 psi boost on street radials with 0 psi launch got me my first 13 sec pass, 13.8 to be exact. Last year I ran 14.1 with 22 psi on same tires. The major change was 3200-3400 converter swap when the motor was changed. Do you guys think a high 12's are out of the ? with race fuel, slicks, and 22 psi?
