Thread: Knock Retard

/\ is what will happen to you said motor.

dude give me your gto, you dont deserve it

The pcm does only so much to counter-act knock, thats why it's called knock-RETARD. A stock car will have knock from factory at times. By running more boost without decent flow mods and low octane, your increasing the chances of having uncontrollable amounts of knock. These 3800's are a pretty damn good block (870+whp so far) but if the motor sees knock, it will die. Maybe slowly, you may already be running fine with a few chipped pistons and don't even know it yet. You can't detect how much knock you have by ear, you have to have a scanner that scans Knock Retard. If you want to pulley down, do it the right way and at least scan.
