i see you are using 21083 pistons with big dish in the center - how are you planning to get the CR up again.
you shaved 1,8mm from the engine block?
how much are you planning to shave off from the cylinderhead?
now the CR looks like something about 9,6 with standard combustion chamber...

Yes, these pistons are from 2108 engine. In 2110 engine are same pistons but with lock-ring for pin. Now i must use PTFE-plug for locking pistonpin.Algselt postitas: olaaf

I measured this dish size from 2108 and 21213 pistons and results are very interesting. 2108 dish looks very big, but it is only 1cc bigger than dish in 21213 piston. 2108 13cc, 21213 12cc. But now i get much bigger pockets for valves, and i can use much bigger valvelift.
Now with bigger stroke and after piston modification that dish is only 7cc and that will give big help for CR. Sylinderhead lost about 2mm and CR was 11.6:1 so i get good chance to make little bit modification to chamber and get some more flow space for valves.
Now CR is 11.3:1. I think it is enough.

I knew that possibilty of detonation with sharpe edges, so i gave my best shot to eliminated it.Algselt postitas: PuZuPThat's good to hearAlgselt postitas: Pöhö-Andrei
Now chamber is smooth and without sharp edges.
What are the dimensions of the exhaust header ?
I mean the runner pipe diameter and the end of the header.
And how thick is the pipe wall?
I dont remember runner pipes diameter but maybe they are 38mm and end of the header is 2" pipe (50,8mm). Thicknes of the pipes are 1.5mm.
I will measure these details and give more information during weekend.
