ok what have u guys used for fuel .. i mean race stuff... not the normal gas station pump stuff ? ...

additaves
race fuels
hard liquor ??


ok the last one was a joke .. but i have seen it been used before.. lol

I bought a bottle of Ocatane booster from auto zone, noticed no difference.

laquer thinner

toluene, or how ever its spelled.

its like at 114 octane, put like 2 gallons in your tank and fill the rest at the gas station(celica tank) and it will bring 91 octane up to 94.

i put 1.5 gallons in my WRX when i only had like 6 gallons of gas in there. the car ran a lot smoother.

i use 100 octane gas + some time nos octane bouster and i thing that it helps the whole fuel system to clean it self..... i do notice some extra hp but not much.....

i use octane booster alot, but all it does is make my car run smoother. You can say that my car backfires less when i'm using octane booster, but that's all. No power gains.

I do know where to get 100 octane here, but it's expensive. So I'll just wait and buy some when i take my car to the dyno.

I think octane boosters and aditives wil only help non-us celicas or engines. The stock 5s and 7a if will not do any thing dif, maybe clean it up a little, but thats it.
