Default Those with 11.5+ compression

Can you list your compression and what type of fuel are you using on the street/strip please

I'm making up my mind on going from 11.5 to 12 or maybe 12.5 on my 402, but octanes are the only thing backing me up..

13:1 here I run 108 octane on the motor. but 116 on the juice. a little over kill, but i dont want to go boom bitch.

We have run pump gas on a 12:1 motor before. Alot of it has to do with tuning

Our NOS engine was 15:1. We used VPNOS and sprayed 600 on a SBC with no problems.

15 and 16 compression

Do you guys think that 93 oct is OK for 12/12.5?

Maybe 50/50 with 93/110 for nitrous use?

Ours is 13.5-1 I think I can make a street tune for it to run on 100 unleaded but when I mean run I mean barely with a rev limit of like 4500 and all the timimg pulled.
