    A while back you guys had a conversation about octane.
    This weekend I tried some C-12 ( 108 octane) fuel for a bog race.
    What a noticable difffence.
    The response time on the engine was a lot quicker . I could rev to 6000 rpm on a dime.

    The pit was 200 feet long. Used four gallons of this stuff to do 4 runs. At the end of the last run I freaking ran out of gas.
    It just sucked it up.

    I would not reccomend it for wheeling :)

    heh heh... uh oh... Now you're addicted. Time to step up w/ the big boys and run the 110 or worse yet get into the 116 leaded [​IMG], but for the rate the beasts who drink this stuff go... the $5-$10 a gallon price is killer!

    Yeah, I like it! I think next time I'll try one notch higher.
    4 gallons for 800 feet. Ouch. It cost me $65.00 canadian for that.

    If I remeber right;
    A top fuel digger burns up something like 5 or 6 gallons in a 1/4 mile pass!

    If someone was to kick over a 5 gallon bucket, it would still be pooring out by the time a draggster poped the chutes.
    Now, thats poor gas milage! Gawd forbid the EPA should get wind of it!

    On the airplane fuel. I used to work at the local airport pumping gas. I don't remember what the diffrence was. But I was told not to exceed 50% in a tank. I used to put it in my dads j**p. He had a custom 30 gallon tank that ran under both front seats. I would go down to the 76 station and fill it up half way then go back to airport and fill the rest with 116 octane. My dad never did now I was doing it. He couldn't figure out wy sometimes it ran so much better. Back then he had a pumped up 350 in it. Know he has a 283 with a edelbrock efi. If I ever own a J**P again it will be that one. Has for the 110 octane now. I use it in my gokarts it cost $6.50 a gallon but man it is a world of diffrence in a one cylinder motor.......Dan

    Sorry so long. It brought up some old funny memerios......

    If it ain't broke.......Don't fix it....

    I have done a few of those on my gokarts. We call them windows. When the rod is thrown threw the block. We all had to go to metal seats after one almost made it threw a fiberglass seat.............Dan

    If you have a built motor, especially one with high compression ratio, then higher octance can help. On the other hand, higher octane generally will not make any difference in a well running/tuned mild stock motor.

    Contrary to popular believe, the octane rating is not a measure of how much "power" is stored in gasoline. Rather it is kind of a basis for the flash point. For example, if you are running something like a 10:1 or 11:1 compression and try to run regular 87 octane you will get "pinging" or detonation. This is caused by the fuel/air mixture exploding (due to being compressed too much) before the plugs fire. The higher octane rating means the fuel is harder to burn, meaning that it can be compressed much more without exploding.

    Not only that, I believe I have a link to a car mag write up (with dyno tests) that stated running octane higher than the motor needed, hurts power. I'm betting it has something to do with the higher octane=slower "burn" thus, with high compression, the cylinder temp is already higher, so it burns fine.

    That makes since. My dads 350 was pumped up a bit. To much. He went threw a lot of drive lines and axeles. That is wy he took it out and put it in my brothers camero. Then he went with a almost stock 283 and just 2 years ago put the EFI on it. That thing sure did run good on the higher octane.......Dan
