After thinking my false knock was fixed, up jumps the devil again. With straight race gas, I can't push 15 pounds of boost into the motor without pegging the knock detector. It retards the timing so much that I fall flat on my face.
Again, it pegs the knock detector on a short stab of the accelerator in park or neutral. Yet, I can bring the motor up to 4,500 RPM against the transbrake with absolutely no knock indicated.
I'm starting to think that something in the drive train, some rotating part might be giving me knock indication. How about a pinion angle problem. I know I'm getting obscure but it's out of despiration.
