is there such a thing as a best piston rings?

I am in the process of piecing a 370 together and would just like to get some info and make educated decisions with my money.

 

Plasma top ring or a steel top ring

 

I'm sure everyone on will agree, Hellfire...Diamond's are fine too.

 

I use the Total Seal rings with the steel top rings.

 

hellfires are supposed to be some of the best. i would be going with them if i didnt have custom pistons and had to go with the weisco GFX nitrous rings

 

Well I am definatly going to be going with Diamond pistons so their rings are fine or are the total seal rings better?

thanks for the responses.

 

I believe diamonds are total seal

 

The total seal ring i have are there blower & nitrous rings. I had Diamond rings in my old setup and trust me there not the same rings. The total seals top ring is steel and the second ring is cast the Diamond top ring is Ductile & second ring is cast. And the Total seals cost about twice as much. I payed 250.00 a set and well worth it.

 

What about premature cylinderbore wear using the HEll fire type material rings ? Won't the steel top ring wear the bore faster compared to a ductile iron ?

 

I have diamond's in mine and hit it with 300+ many times. No problems.

 

Steel ring don't put out much more side pressure than the Ductile rings, Its the durability of the rings. The steel rings has a more ring gap the a standard ring does. On my nitrous motor the top rings has a .035" ring gap. That sounds like a lot but Total seal told me its because the steel ring will expand a lot more than a standard ring will.

 

get the hellfires.
