Quench Vs Piston To Head Clearance

ok im just give some variables and you guys can fill in the blank.

if you have an open chambered head but the piston has a step to act like a closed chambered head wouldn't that give you quench?

First, let's get distance set up. You start to loose the effect of quench when it is greater than .055, or as I'm told.

what area are you measuring the quench from?


Getting it tighter is a good thing. It does how ever depend on the rod material. A steel forged rod is pretty standard and can get to .035 easy enough.

.035" meaning .035" of head gasket or .035" to the largest volume area of the head? or??

But an aluminum rod will stretch a little more. Take note of the rod manufactures suggested limits.

yea understood the aluminum will stretch more.


this seems to me to be two terms that are either directly related or are the same thing. Rumble whats a minimum piston to head clearance (flat top with flat closed chamber head)??
