On my car man, 35psi from a t67 h.o. It was never dynod at that psi, made 481 at 18psi, and going by what i was gaining per psi on the dyno, what the turbo is capable of, what I was seeing for injector duty cycles on ID1000's at 60psi base pressure. Its a pretty realistic guestimate. Didnt need a dyno to tell me I was close to that. Ripping apart street tires in 5th gear just pounding the limiter on a fresh paved highway leaving twin tire marks behind me to well over 160+mph, I know how much power it takes to do that. lol. And how much power it takes to rip apart 25X8.7X13 slicks at 10psi all the way down a 1/4 mile track and trap nearing 140mph wasting a lot of acceleration time.
My Eagle rods have seen nothing less than 450whp and have 15k miles on them ranging from 450whp to roughly 550whp on the 60 trim on 30 lbs, and roughly 650 on the T67 h.o. on 35 lbs. Still in perfect condition.
