well, mine's 12:1, and it's a daily driver...

now, from what i understand, compression can be as high as 12.4:1 on lt1's without a worry [running 93 octane]. but how true is that? can the car really be kept from detonating with that kind of compression when ur spinning at 6500 rpm?

so, i'd like to hear what compression you fellas are enjoying with pump gas.

 

12.5.1, but I'm up here a 5,600 feet elvation. When I'm out of race gas, it's on pump 91 octang, and runs perfect. I'm sure I wouldn't be so lucky if I was at sea-level..
