Detonation

NitroNixon · 04-13-2004, 10:01 AM

What does Detonation sound like. I bumped my timing up to 16 and took it for a spin. When I drive the car normal the engine sounds fine, but when I floor it I can hear a slight pinging noise coming from the engine area, almost sounds like a quiet rattle. Is this detonation?

Before I bumped the timing, I could floor pedal and the engine would sound fine at higher rpms.

With any stock or near stock combo such as yours I would not run anything more than 14-15 degrees, safely.
