I have a 418 ls3 with plasma moly rings and want to add a turbo kit to my car . I have been told they are fine for boost but others have said they are no good. So now im confused . Does Anyone here have experience using these rings with boost and how did you make out with them.

thanks

I have heard the moly wont hold up to the heat over-time and will flake off. Put a good top ring in it made for the heat or run what you have and re-ring it when needed.

I've used plasma rings for moderate boost with good results. Just be sure your tune, is dead on and ingap is right. They won't take the abuse like a stainless, or hellfire.

Long as it's sealed up good I wouldn't rip the engine appart just to change the rings, but If It's appart I would prob go back with a steel or hellfire ring if you plan on pushing it really hard.

I would tear it apart to change the rings before it's too late. I was sent moly rings by accident when I ordered the steel rings and didn't catch it, put them in my motor and the moly coating flaked off and fucked every cylinder wall and two pistons!

Sounds like maybe there was something else going on there. Was it detonating, or rings butting? I've used the plasma mahle power pack rings and pistons on some builds well over 1KHP and sealed up fine. What brand rings were they?

This wasn't on boost, this was on a 350 hit from a direct port and I was just starting to get the fuel ring right on the plug and make some steam on the tuneup (was nearing perfect, but still a little fat), there was no detonation and my ring gaps were loose, I gapped them with plans of whacking 500 horse worth of nitrous! I don't know where the plasma moly's would hold to on boost, but I wouldn't leave them in till they flake, because they could do a lot of damage if they do!

BTW, sealing wasn't an issue, it was just that the moly coating flaked off and scored the hell out of every cylinder wall/piston and then the sealing went to ****, haha.

I could see that happening with n20 that stuff is harder on things than boost. Well turbo anyway.
