My bad, I read the 1st post and did not see the pulley size later of 3.625.. Love my 651 RWHP @ 10.9 PSI was just curious.. Guess I should have read the entire postOur test car does not have 13psi, we have seen spikes at the RPM limit of .5psi more, and the original cal had 1psi more boost with different cam scheduling.
10.9 is 100% correct with a 3.75" pulley. Change to a 3.625" and that will add 1psi more, 20-25rwhp.
