New dyno on Sunday (2 pulls)
----------------------------------
The FR500 (4.6) Cobra made 2 pulls on Sunday. I wanted to see if the HP has stayed the same or increased a bit ??
I upped the rev-limiter to 7600 and pulled both times right up to 7600. Result; I made 1-2 more HP at 7600 (410 RWHP - DynoJet SAE), than 7250. Torque remains unchanged. It is so hard to imagine that the HP has not peaked with those heads, intake, and valvetrain by 7600.
No sounds of float, knocking, detonation, or anything unusual; just a roar. Aggressive !!!!!
I see Naz has raised his to 7750. I really believe that the combo will pull to 8000.
I am not willing to try that much yet and lowered my limiter to 7400; which, by the way, I hit everyday now. No issues.
