I was hoping and estimating low 230s hp with the addition of the PI intake and FRPP and came close. Charts are posted below. The results are a gain of 7 max. hp and a loss of 9 max. torque. I am still running stock timing with 87 octane gas, so maybe it's time for a T/A or chip and premium fuel? Previous dyno was done with Steeda Pulleys, PI cams and Bassani catted X.
SAE dyno results. I know it says STD on the charts, but I saw them select SAE on the dyno and was assured it was just the chart label.
SAE dyno comparison with PI intake and FRPP catback added
AF ratio on the first pull
Some possible explainations of the tq going down from the guys at Mustang Magic, is that the car is running rich due to the PI intake and compared to last year's temperature was 20 degrees cooler which makes a car run even richer. I'm of the opinion that since the runners of the PI intake are longer than the NPIs that is why tq. went down and hp went up.
I welcome your comments.
