considering coating the pistons for my build. gen 3 hemi under bewst. intercooled. 9:1 comp. what do you guys think about thermal coating. this gen 3 and bewst will be new to me so there will be a learning curve thinking about it for insurance but would it be a waste ? its a reverse dome forged piston with side skirts already coated.

I would do something for a coating on that piston. Scary close relief for boost.

Sharp edges are NOT your friend... yeah i was looking at that and thinking detonation city... there are some awfully thin bits on the top of that piston, is it a shelf or custom?

My 572 hemi pistons were spec'd for a heavy dose of nitrous and got the domes ceramic coated by Diamond. It's the tan or gold colored coating. Can't say much for it as they've been that way since new. Haven't hurt one yet.

I thought moly rings and boost don't mix cause boost knocks the moly coating off them..... You think I was surprised when the Moly was knocked off and the ring failed Nitrated titanium next round,,,,,,,,
