oo but has anyone done this though????

seen affects

like i heard you can hgain as much as 30 hp off using it

is that true?????

sjs

Is there a guide as to how much toulene or even higher octane gas mixed with 93 octane = ? octane?

image4you2see

Well if your car is stock alls your really going to do is slow the car down......High octane gas is not needed even on slighty modded cars.....You really need some thing to make more spark to burn that fuel before its worthhaving in there......You need more air also but thats a simple mod.....Dont waste your money is what i say......Hell I have a highly modded gm product that runs low 11sec on the bottle and its a pump gas car........So in my opinion its a waste of money.....

Higher octane gas is harder to burn, so you won't gain hp. You may actually lose hp if your ignition system can't burn it.

My freind just go to a small local airport and pull in, fill up, and leave. They have a credit card machine there so you just swipe your card and fill her up. These cars are a Single Turbo FD, Single Turbo Supra, and a TT Supra on the bottle. It is $2.30 or something a gallon as of last week. I plan on running race fuel for drag racing and dyno pulls but mostly I will run pump gas in mine. I am in the process of putting my Race ported motor in w/ a T78. I have all the fuel, IC, ECU, Ignition, Exhaust, etc..mods that I need. I have not heard any real downsides to using it on high horsepower applications.

just buy VP...



Anybody here take apart a motor with av-gas in it?. It looks like a million mile diesel. Avation fuel is sooty, unpure and complete ****. Just smell it and look at it in a clear glass, it looks like dark tea, if you are required to run on high octane fuel..your not tuning it right. i suggest you buy VP fuel for track days/street showdowns. take it from somebody who is sick and tired of ppl cheaping out and blowing up motors with that crap.

i htought aviation fuel is clear light blue?

I've said this before, I just don't know if it was on this site.

All higher octane has is a higher resistance to pre-detonation. If your car isn't tuned to make use of that there is no reason to run it. There are only a few ways to benefit from higher octane: higher compression ratio, more spark advance, more boost, or some combination of the three.

So on my N/A motor where I'm not allowed to change the compression ratio (because of the rules of the class I race in) The only way I'll be able to make more power (through the fuel type) is with a lot of spark advance.

Silver Ninety Three, your statement is exactly correct, higher octane fuel burns more slowly. It's not "harder" to burn.

You make total sense travis.....but still AV gas is crap. Black soot everywhere!
