what would the 11:1 piston do for the xx ? more top speed ? more torque ? is the piston a plug and play thing or would you need to bore the engin out

Smoooth is a member here(I ported his cylinder head) and $240 really isnt a bad price for custom CP pistons, Raptor guys regularly spend $250 for custom CP pistons.

So if someone goes with the 12.1 how much more power does it give? any dyno on it?

I do not have any numbers for the 12:1 alone, You'll get a few hp and a notable increase in torque

You will also have to run high octane race fuel with high compression pistons. I'm sure most people know that, just thought I'd mention it in case someone didn't.

You will generally get about 3% Hp increase per full point of compression increase.
