whats the highest compression you can have while not having to use racing fuel?

 

wow, this has been brought up a gazillion times in the past month, SEARCH

 

Kieth the guy has 2 posts cut him some slack man, you asked all kinds of Dumb questions when you got here. So maybe you should remember what it was like when you asked 100 times, what cams are better. and try to help him out before making him feel like a *** bro

 

Yea, but the guy shouldn't even need to search, there have been at least 3 questions on the first 5 pages....
sorry to be a dick, just look at a few pages, and if you don't know how to use the search ask.....many people can help you, it's just I've heard the same question a bunch of times this week, although I've been known to ask the same question until I get the answer I want
12.5:1 on 93-94 octane is good
and 12:1 on 91octane
