Alright guys I have been replacing everything on a pretty clean 70k mile car to help track down a knock problem. I thought it was a fuel problem, but now I just dont know. Heres the symtoms:
Very large knock under any load. I get knock with any boost or under high rpm even in park. I get KR from 5 to 38.
Things I checked and replaced:
I put a new walboro pump and harness from racetronix, new accufab fuel regulator, new fuel guage. I set FP to 45psi line off drops to about 38psi line on. I put 100 octane fuel in it. Checked for loose exhaust, flexplate bolts and anything else that might be hitting. I am not sure how to get readings from the scanmaster for diagnosis at WOT. Would readings at idle help? I dont hear any physical knock. I have the knock checklist but wanted your inputs as well with these symtoms. Would a knock sensor go bad just under load and be fine the rest of the time? Please give any sugestions I havent been able to spool up for almost a year. I cant take it anymore.
Specs:
Engine was built by Cal Hartline with specs as follows:
.020" overbore, forged turbo pistons, speedpro rings, billet main caps, double roller, 210/210 cam, Champion GN1 aluminum heads, ported stock intake, ported stock intercooler, 40# injectors, dual fuel pumps, new TE-60 turbo , Terry Houston 3" downpipe, ATR 3" crossflow dual exhaust, dual thermostatically controlled fans, external oil/trans cooler, new alternator, water pump, battery. PMAC tranny with raised stall stock converter.
