High compression pistons.... How high?

anyone offer a really high compression piston? like 14-15:1 Or shorter pushrods if I have to cut the head to get my comp up that high...

anyone checked with comp cams if they make a forged one piece formed tip pushrod yet? Im sure its a close size to something they have or possibly willing to cut specially for guys like us.

and if you ask why I'm looking for this stuff then yes I'm looking into building a nasty e85 engine.

12.5 HPD are the highest I've seen... But, To be honest with you, the 800 engine doesn't lend itself easily to very high compression. The ports, combustion chamber, and general engine configuration are just not great for high HP NA applications. All the normal stuff produces small gains. And a lot have tried. The best big bore high compressin kits advertise 20+ hp gain, but on the dyno they prove to be 7 -8 hp gain. HP per $$$ is just not there.

But.... blow a little boost in there, and now you're talking. They respond very very well to boost. Especially if you know what you're doing with e85 or race fuel.

Re: High compression pistons.... How high?

next year I'll be running a race series that doesnt allow any power adders like turbo, supers, or No2.... need all motor 800, no big bore allowed.

I wanna stick with cams, springs porting and high comp for e85. rules dont say anything about fuel

I have a box full of everything i need to turbo this bad boy, but I dont want to fab it all up and have to take it off for next season. I'm a turbo guy personally.... just cant get away with it yet.
