Re: 11:1 Cr

i run 12:1 on pump gas (93)
FYI, its the DCR (dynamic) you need too worry about for octane ratings (too a point) not SCR (static)

you will more then likely be fine....
stock is 10.5:1

This DCR you refer to, what is the real intent/purpose of such a calculation? What is really gained by such a calc?

Plenty of local people running around Raleigh here with CR's well north of 11:1. No problems at all on pump gas with a good tune.
