Default 12:1 or higher comp on 93 pump gas?

Is this possible? Are any of you guys running this now? With proper tuning of course. I would think so considering I know a few who run boost on 11:1. Just wondering how high you can go.

12:1 on 93 octane can be done if you have a good tuner.

itll be higher. according to sgt who uses ctr pistons on a lot of his motors, itll be 13:1 with ctr pistons in an itr block. FWIW, i ran ctr pistons and a mugen head gasket on my itr motor in my old car, which put it close to 13.4:1 with stock injectors, a fpr and a vafc. I had slight knock at 3.5k to 4k at partial throttle, but with hondata im sure the prob couldve been fixed. 93 octane btw

Well for 95 i pay like 1.55$ a gallon . I never use the 100 or 110 but the 100 is like 2.00$ a gallon and the 110 is i think 3.99 a gallon

where the hell are you getting 94 in MD? I live in MD. I ain't seen anything over 94 since Sunoco had some until the chief of fire departments told them they can't carry it anymore because its a safety hazard.

I would say so. You wont be living with much of a problem. I see people do it all day. Make sure timing is correct, and make sure you run AT LEAST 93 and you are good.
