What Octane?

[GRUNION]

What octane are you guys running? Im running 92 in a 502 with a super charger. Think it would hurt to run cheaper gas?

Why risk it? Hell, just run 100 now, because it's almost the same price as 91...lol.

I think it would.....If you are running more than 4 or 5 lbs.....assuming a static cr of 8:1

Too much octane is never a problem. The one time you don't have enough octane, you are in for a big problem.
I run AV gas in anything high performance all the time. For the .15 per gallon difference, it is cheap insurance against a major failure. :)

There ya go. How much money are you going to save when you get an octane knock and end up detonating a piston or worse??? You can buy lots of gas for what it costs to rebuild a big block. ;)

Isnt there a problem with running straight av gas. I know its made to run at altitude and at a low rpm.
And I wasnt planning on running a lower octane I was just wondering what you guys thought. I hear people say different thing all the time.
