I have 11.1 compression and I run sunoco 104 unleaded racing fuel. <img border="0" alt="[devil]" title="" src="graemlins/gr_devil.gif" />
What kind of octane should you run? It depends on your compression ratio and timing. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
Good luck to ya. <img border="0" alt="[angel]" title="" src="graemlins/gr_angel.gif" />

Once I was 11.5:1 and ran VP CSP (96.6 motor octane.)
Then I was 12.2:1 and ran VP Motorsport 103 (99 motor octane.)
Now I'm 16:1 and I'll be running VP C14+ (115 motor octane.)

When I was running on the street I didn't change the timing that much. I richened the mixture up from .850mv to .920 or so. Yes, that lowered the timing a little. Maybe from 31 degrees down to 28 or so.

Re: What octane are you high compression guys running...
In order to run leaded can I simply remove the cats and O2's or is their more to it than that?
What are the positives and negatives of running leaded fuel.
