Detonation at 6500 RPM - ZR-1 Net Registry Forums

wikdzr1 · 02-26-2004

I was wondering if any one experiances any detonation at high RPM. I use 94 sunnoco fuel. Around 6000-6500 rpm I hear the valves rattle?

Any thoughts?

Also I heard a loud pop ( Metal snap sound) when backing up the otherday. Now periodicaly I hear a squeak or pounding while driving. I have pulled the wheel but it looks okay under there. I have also slid under my car and looked at u-joints etc & cannot find anything out of norm. any ideas
