This thread just got me thinking....... I popped my #5 piston ringlands after upping the boost from 6 to 11 psi and up to 715rwhp. I was running -6 plugs when i was 6 psi and 637whp.

When i pulley'd down and added meth the shop i used at the time did not change out the plugs to -7 heat range. Just the smaller pulley, meth and tune.

Six weeks later and 6 gallons of meth my motor copped an attitude and there went #5 on the factory motor. Wonder if a cooler plug would have made it last a little longer.

I was on a mission to see how much crap the motor could take, and it held up pretty long. Just wonder if a cooler plug would have prolonged it a little longer

Food of thought.
