are there some soft numbers of how many hours/miles?
What are thoughts on the ring seating products that promise very quick ring seat intervals?
I have used some of the "paste" in the cylinders before that is supose to fill all the low spots and promote better ring sealing.Quote:

Denny,on the dyno the water brake will take care of this issue.Quote:

With todays material being processed for the rings, The backloading takes care of itself if you are willing to apply the "vacuum" process Denny suggested. Most importantly for todays rings, Heat sink them. This simply requires running throught the process of break in and parking the darn thing for at least 1 half hour. You're done.
Rings today are a much harder than they where 10 years ago.Quote:

Erik Always brings to the forefront An idea or technological quizzery that I dearly miss. Thanks Erik, I was wondering where you were:LOL: Good point bud, let's find out whether these are coated or ductile sets of rings as for sake of discussion. Also, who set the clearances and double checked the performance under run conditions. One thing that is a constant; HEAT. It has to build the tempermant for life of the engine during it's cycle for life. chrome, "moly's", cast which ever you have set the system up for will need the heat to set. Thanks for bringing the reminder of the construction of the rings forth and what material they could be laced with, they are much better than they ever have been for the longevity purpose of our builds. I appreciate your endevors with your posts Erik.
About twenty years ago if one of the dirt burner cars hit 250 F to many times you would loose your ring seal.Quote:

With today's better ring material you can hit 250 F and not loose ring seal or blow head gaskets.
I would rather keep the temp. at 200 F for max. HP/TQ and longevity but this is not always possible.
