Will a -20cc dished piston hurt performance compared to a flat top piston if the compression with either pistons be around 11:1 running a 200 shot of nitrous?

 

no it will not hurt you.

I am running a -16cc dish, 12.2:1scr, and a 200 shot

 

Great, thanks!

You must be running either a very small cc or a large ci or both. What kind of times are you running with the 200 shot?

I finally hit 10.94 @ 125 with a 1.64 60ft in 94 degree heat. I really need to work on the rear suspension because the rear was bouncing around on the launch.

I was running a 48cc combustion chamber on a 396cid motor

best NA 11.31@119.x (1.59)
Best NX 10.48@129.9 (1.49) 150 shot (good weather)
latest 10.56 @ 128 (1.58) 200 shot (massive wheel spin & 2000+DA)

 

flat tops allow for faster flame travel, or so ive read,but i dought youd be leaving any more than 15 h.p. on the table with the dished.
