Ron,

I've had the Total Seal rings in two street/race engines but I can't tell you how long any of the rings last on the street. I've never worn any out. I freshen my race engines every 18-20 nights and my street/race engine after 2000 miles, mainly due to the number of times they've been heat cycled and also to get new springs and lifters in them.

The gas ported pistons seal the best, but with gas ports the ring pushes so hard on the walls that moly rings have a very short lifespan. Titanium nitride or chrome nitride lasts longer but they're hard on the walls.

I wonder what rings Hal Copple has in his with 50K miles on it.
