too much meth = knock? - Page 2

Most race shops recommend running copper plugs because copper will melt before most other metals. That way (in theory) when you run your temps too high, the $2 plug goes instead of a piston or valve.

^^^+1. Another safety reason for those high strung motors.

oohhh thats why your going trough plugs. there cooper. try iridium and then see what happens. also i thought that our motors are sleeved with steel or cast iron because the blocks are aluminum. so i dont see how the meth would eat at the cylinder walls.

So back to the OP...

You are asking us if your car is experiencing rich knock, but you're not posting any logs and you're not telling us what AFR + timing + boost you're going for.

Please give us enough info to intelligently respond to your questions
