doesn't that have to do with npi pistons + PI heads yielding a higher cr?

Early Christmas to me. Brett's porting my midplate and plenum. In the spring, he's going to try a "torque port" on the blower vs the race port. Should work well with the accufab

PI swapped heads on a non PI bottom end? The higher the better. But with a conservative tune, I don't see why you couldn't run 87. 93 with an aggressive tune would be freakishly awesome though! [MENTION=76842]Carcrazygts2[/MENTION] runs E85, but he may have more insight.

I thought as much. This seems like it would be a much more viable option for me wanting to stay n/a.

Lol Maybe... Actually it probably won't help much. After taking to brett and told him I'll be towing with it, so he wants to try a torque port which will help power and torque down low in the band vs a WOT run.
