Ok, so now that the afterglow of dyno day has worn off, I’m looking at my numbers a little more skeptically…

02 4.6 2v 133k Miles
P1SC-2, 3.9 pulley, 3 core cooler, Power Pipe
C&L plenum, 78mm TB
Long tubes, orx pipe, magnapack catback
91 Octane


Honestly, i was expecting 380ish for hp. But it pulled 423.7@5800 and 433.9@4400. The original dyno sheet has
different scales on the left and right sode of the sheet which makes the hp look a lot higher than the tq…i redrew it with the same...

Procharged FBO 4.6=424hp 433tq……..?
