410 supercharged

I do not claim to know everything at all.

So you are saying that a 0 deck with .039 head gasket will have the same effect with a 0 deck & .125 head gasket in a Forced Induction application.
The goal is to stay away from Detonation the engine killer............

Can you explain?

Essentially, yes. You would just make the difference up by the blower speed. Quench in that instance can actually cause detonation. The effect of quench in a supercharged engine is so small it is negligible at best. I can't explain it in depth, because I don't know everything either. But I have built a few blown engines. I have spoken to some experts such as those at United United Engine, Dyres, B&M, and Hampton Industries. In fact, it is the general concensus among those who are in the business that a piston "in the hole" will make more power in a blown application. Something about having more area to fill the cylinder efficiently. You cannot compare what works with a naturally aspirated engine to what works with a blown engine. Blowers change the fuel curve tremendously. I would recommend you call and speak with the tech guys at United Engine. They are all very sharp. I have worked with a couple of them pretty closely on a few builds in the past. I spoke with Marco there in fact just yesterday about a blown engine I may be helping someone on in the near future. I won't sit here and say quench does absolutely nothing in a blown application, but it's effects are such that you would likely never see benefits from using quench on a blown application. Call them. they can explain it much better than I.
