Fuel question
Fuel question I am thinking of going back to the track again soon. Can I run some of the 110 octane fuel they sell at the track in my LS1? Its pretty much stock so I wonder if it would hurt it more than help it? I was just going to put a few gallons in an almost empty tank of 93 octane.

for my setup though i will/can benefit from the higher octain due to my higher compression.

Octane Ratings are basically how hard it is to get the fuel to ignite. A high compression/high boost engine needs high octane 110 or so to keep the fuel/air mixture from igniting prematurealy (knock)
On a stock car it wouldn't help and might even hurt to run race fuel.
