Anyone running Full Dish pistons N/A???
 

Kinda a continuation of my other thread.

Anyone running a N/A application with a full dish piston like a Mahle???

If so, any problems??

Why are you wanting to run a full dish N/A?
Why not run a stock chamber'd head with say a 6cc dish and 2cc for valve relief?
that will give you a shit-ton of P-V clearance, and get you right around 11:1

might keep tabs on this thread too.

even though its talking about boost, its still relates to quench, detonation, etc..

I had the motor built before I knew anything about quench.
I was to run boost sooner than later, but some things have changed $ wise.

Now I have full dish pistons on a motor that will have to run NA for some time. Thinking I should change them out.

I am 11:1 (close to it) with -12cc full dish pistons as it is with these.

38 cc chambers and around 37 cc's dish piston going in my 434 n/a motor. look at the engine masters challenges and notice their affinity for dished pistons and small combustion chambers

I think detonation is a much more regular problem in a boosted engine... thats why I will not go full dish with my turbo setup. I want that quench deck for safety. I am guessing an N/A engine won't be as sensitive. Full dish seems to be the way to go if you're going all-out.

Thinking about the small chamber and a dished piston...a lot of diesels have the entire combustion chamber in the piston... and flat heads!

He is talking about a fully dished piston with only a small skirt of quench deck around the outter ring of the piston, not a reverse dome dish that matches the combustion chamber (like what most everyone runs these days). The pistons I remember seeing in those engine master challenges all had reverse dome designs (but I don't remember any specifics).

He is talking about a piston like this
