Higher compression pistons

Do we have any high compression pistons available for the H2? I’m thinking of going with 10:1 or higher, maybe 11.5:1
With the intercooler, and E-85 ( VP X-85 ) I should be safe.
Just can’t find anything, trying to see what’s available before I have some custom pistons made.

You will throw a standard rod through the crankcase.

Why in the world would you think I would use a stock rod!
If I go through the trouble to have custom pistons made, your **** right I would use at least a set of Carrillo rods.

H2SX has higher compression as original equipment. Not sure how, or what other parts are different to allow it.

FYI as you increase power to a much higher level your spark plug life is awful.

I only get 2k miles out of my spark plugs and they are done!

That is why i bought an H2SX, to keep the miles limited on my 400hp H2, as i don't want to be changing plugs every month.

I bet! My Yoshimura Superbike would go through $100 ea spark plugs every 100-150 miles.

You ready have high compression Pistons when you factor in what the Supercharger adds. With any type of forced induction motor, you have to be very mindful of Detonation. That's why it was not uncommon for engines that have FI to have a Static compression ratio of 7.5 to 1. When the combustion Chamber is pressurized It quickly goes up. You have to take that into consideration beforehand. Detonation must be avoided or mitigated at all costs or the engines life span will be severally compromised.
Why not increase Boost?

The old school guys with superchargers used to increase the head capacity to get more fill and bang for the buck
