I hear people speak at a particular boost you should use hellfire rings but I also hear at a particular rwhp. Depending on the engine and heads as we all know some require more boost to reach a particular rwhp. Obviously an ls7 will require less boost than an lt1. So should we be getting hellfire rings based on the amount of boost or the amount of rwhp?

 

I'd suggest you get total seal gapless rings

 

The only reason I ask is because I'm about to purchase a Z06 and knowing me I'm going to start building a turbo engine on the side hoping for 800+ rwhp. I will want to drive this on the street. May put 5,000 miles a year on it. I just didn't know if this is possible if I have to use rings that are tough on cylinder walls. So that's why I brought up boost vs rwhp.

 

hellfire rings and street don't mix. Best thing to do is give total seal a call

 

Many are fine on the street with LS9 or similar gaskets.

 

Total seal AP set here...

 

Total seal.

 

So they are easier on the cylinder walls for street use and can still handle between 15-20lbs of boost? Which total seal rings?

 

best thing to do is call and talk to them, they are very knowledgeable. For what it's worth for my LTX 4xx twin turbo engine, they will be in there. My old 383 LT1 twin turbo engine they were in there

 

Arent hellfire rings a gasket sealing technique?

Total seal the same or a piston ring?

 

Any steel top ring is going to cause more wear than moly rings.... But when your running boost there aren't much options out there... IMO

 

I've been using a moly ring since 2005 on my iron 6.0l avg boost of 25psi and hit 30psi many times. My gap on top ring is .028. That's the secert to run high boost is the gap in the top ring. When hot rod mag did that big bang 5.3 test they used stock rings but gapped then at .028 top ring. They hit over 1k hp on that almost stock engine. Something to think about. I have over 50k miles on my engine.
