All my dynos where on a Mustang dyno. On 25ish psi I made 395whp, on 28 psi I made 423whp. Then when I had a built motor, cams, and meth I ran 33psi and never got a full pull. I think the head lifted. I made it to 5200rpms before the radiator hose blew off, lol. At that point it was still building power, but had made 449whp and 475ft lbs.
