Disadvantage of Steel Piston Rings & Wide Ring End Gaps?

[PurpleBeeper]

I'm building a 99% street nitrous motor. I'd like to build the engine to handle a 250-300hp nitrous shot. I'm pretty settled on some Icon 2618 forged pistons, but what about the rings? The Icons use 1/16", 1/16", 3/16" rings. I've previously run 125-150hp nitrous shot, but this is a new level.

I'm reading some things that say:
1. 250-300hp of nitrous is too much for chrome molly or cast rings & is in the territory of requiring steel rings.
2. I should probably run a high tension oil ring instead of the more typical low tension oil ring.
3. I should be running a larger ring end gap to compensate for ring expansion with the nitrous.

What kind of disadvantages would I have on a street motor running loose steel rings with high tension oil rings? I would expect more blow by, but how bad would it be? Can anyone offer some ring advice for my application?

Thanks!

Moly can flake when subjected to detonation. I’d run a stainless ring. Big gap hurts nothing. Keeping oil out of the chamber will prevent detonation from charge contamination. You can still have detonation but it will have one less contributing factor. Just because a piston is forged doesn’t mean it’s up to the task. Thick crown and pin with lower ring placement. Contact Dodge 330. He’s a member here. Sprays the heck out of a stock block street combo that’s dipped into the 9’s.
