Assuming you'll run somewhere in the mid 10s on motor... you're probably giving up 5 tenths to an optimized NA combo.

OK but how do you guys figure out how much power it should make? Is there a reference guide out there or something? Thanks and that means I should gear it for 6500rpms N/A correct? SO that will mean 3.73 tops.

i would figure somewhere around 450-500rwhp on motor, and then your adding a 250+ shot on top of it. i would say 700+ rwhp, give or take. i would put a 3.73 or less in there.
