More Compression is More Torque throughout the powerband on a combo like that. That motor might do better with a dual plane or a Ported street dominator than that particular single plane.


Agreed.

We run 11:1 on pump gas 93 in the 505 with no issues. Probably could go lower, but never really wanted to mess with it since I have 93 right down the street from me.
