I run these pistons:




And 25 PSI of boost.

I'm not on E85(C-16) but it does work rather well. And since you are a dedicated autocross car, the cost of the fuel shouldn't be overly prohibitive. I spend about $80 in fuel for a Pro Solo with a codriver.

When I rebuilt the motor this winter it calculated out to be 10.36:1. I would consider going higher but then my valves and pistons would start having "space" issues.

Stock cams? Now you have me a little worried.

Stock cams...yes. stock cam timing...no. I also have larger diameter valves. Some time with a rotary file in the valve reliefs could fix it.

+1mm valves here with higher lift and non stock can timing by default with longer duration. Hope I can make it work.
