Cause of lifted ring lands on pro charger motor
 

As it says , what could be some causes of lifted ring lands on a procharger motor ? This was a fuel injected motor

Detonation.

Detonation is caused by too much timing, engine to warm/hot, too much boost, lean afr, and octane of fuel.

Give us more details and we can figure out why.

I learned back in the late 70,s what detonation was when I blew a hole in a piston with a 850 HP gale banks twin turbo setup.

Sorry OSO. This double posted some how ....
