so what octane do most of you run? is it pump gas or is it race gas? is it a mixture of both?
now if you run race gas is your car really a street car?
also if you ran race gas do you think you could actually get it to run on pump gas?
this would also define what is a street car and what isnt, adding octane at the track is ok but if you have to rely on it, it isnt a street car for the average wallet
The only reason that I can think of that you would need to run higher than street octane levels would be for high compression heads (and maybe with nitrous - I don’t know squat about nitrious). Octane is simply a numerical representation of a fuel’s resistance to pre-detonation. Fuel will spontaneously combustion at a specifc temperature or under sufficient pressure. The higher the octane level, the higher the resistance to combust before seeing a spark. Unless you are seeing high head temperatures or have a high compression ratio, race fuel is probably a waste of money. In fact, if you are putting higher octane fuel than recommended in your owner’s manual on a stock engine, you are likely also wasting your money, unless you know for a fact that the gas has additives to clean your fuel system.
Over the years, alot of people seem to be under the impression that octane is a measure of per-unit energy of the fuel. That’s just not true.
I run 93-94 octane in my road race car even though I could probably get away with 89 just because I know I am running at excessive high temperatures. I would prefer to complete avoid the kock sensor from retarding the timing on the track.
also boost levels would be a reason. i know when i was running 12lbs i would just use 93 but could def get away with 91 but whne i was running 20 lbs in the srt i always ran 93 but when i went to the track i tossed in a few gallons of 110.
run 110 in gn 26-30psi u need it…but im detuning car to 93 octane so i can drive more!!! it does get costly to drive with race gas all the time!! i might get alky for it not syre!!GTP runs 93
