More compression or flat tops

[CamKing]

So Mike more than likely make as much or more with flat top, less compression and matched cam for compression!

It depends on what compression you can get with both types of pistons, and what fuel.
With unlimited fuel, I would take 14:1 and domes, over 12:1 and flat tops.
If your fuel is limiting you to 11:1 with domes, I'd rather run 10.5:1 with flat tops.

Well, what's the max compression you can get with flat tops, and what's the max you can get with domes ?

If i peel heads with down to 55 cc i can get 13.5. With those pistons shown above 14:5-14:8 with chamber 64 cc now

I'm not familiar with Torco 112. Will it respond well with 14.8:1 ?

[Steve.k]

Well we might have to switch up to q16. Thats what we have been using in 13.5 motors with good success.

With Q16, I'd go 14.8:1 with domes.
