100 octane fuel
my 02 z28 has a catback exhaust, slp lid,160 degree stat, msd wires, ngk tr55 and the free air mods.....will the 100 octane fuel have any affect in the 1/4 mile? my best time now is 13.5 at 104.

I've been told that no, it won't, unless you increase timing. lower octane won't hurt it either unless you're getting knock retard. But, that's ujst hat I've read on here. Don't know for sure.

No. 100 octane will do nothing for your car. Higher octane burns slower, which makes it less prone to detonation/preignition, but also less efficient. You want to run the lowest octane you can without any detonation. If you were running higher compression, boost, or squeeze that would be a different story...

well actully if u had the 98,99 or 2000 year camaro then it will make more of a difference becaue those engines are higher compression but the higher the octane the higher the igniting temprature would be for the fuel, and actually u might need that slp timing advance thing to make it work even better but im not sure how good it will work 4 u

But seriously with what you have you don't need more than premium.

Have you been hanging out with ricers?
DO NOT waste your money on that stuff, your car isn't set up for it.
Because I have a blower and a stock bottom end, I run higher than 93 octane just for safety's sake. But still not 100 or more. 1 can of torco with a full tank = 97-98octane. No extra power because the car was tuned for 93, then run on torco for extra safety/prevention of detonation.

It still comes down to tuning your engine for the octane its going to run, or else its pretty much pointless.
