I am building a 5.7 eagle motor for my truck and the rings are paper thin and with 300,000 it still used no oil and there is no discernable bore wear when feeling it up, cross hatch right up to the top of the bore. One important thing though is the oil drainbacks on the outside of the head keep a lot of oil off the crank and therefore off the cylinder walls. A vacuume pump and good windage control can work towards the same end and the less oil on the walls the less ring tension needed.

On my 410 stroker I ran 1/16 rings low tension all around with a dykes 2nd ring and it has no blowby and no oil use at 11.5 compression on iron heads.

A nitrous motor may have slightly different requirements but I am no longer afraid of the thin low tension rings on the street or strip. I bet the hellcats are running a very thin ring also and giving you a warranty with it.
