| If your kit will except Methanol, which has an octane rating of 130, that is what I'd use. If Methanol is too hard on your pump, get denatured alcohol. I use rubbing alky that is 95% Ethanol, little easier on the pump. |

| Klotz lube is about the best. Gives the alky a redish tint. It isn't recommended to use methanol because the pump may not last as long. I have, I use the methanol on the weekends and usually ride around with ethanol for the rest of the days. |

| Ethanol is 115 octane. So it should be pretty damn close to that. If you want a good thrill put some of that RC gas in there. It is methanol, pre-mixed with the klotz lube and you can get it in 15-20% Nitro. My car goes like stink on it. It also smells like a top fuel!  |

The octane of the alcohol has nothing to do with the performance for the most part. Rather it is more related to the ability of the vaporized mixture to remove heat from the charge and reduce detonation. Please note that the above relates primarily to the use of alcohol as an injection spray and should not be considered the same as filling the tank with methanol on a car that is converted to burn meth. Now, if you put methanol into a SMC kit, it will be toast in a few days... Go to the paint store and buy Denatured alcohol with is mostly ethanol and a small percentage of methanol to make it poisonous. You can spray a little wd40 in it if you want...don't use water as only water soluble oils will then work. The performance difference is just not great enuf to screw up the pump.,

 I know you can run 19:1 compression on Methanol, so how could you only have an octane rating of 100?  Why does Stevie Y like Methanol better than Ethanol? | |

| He likes it, in spite of killing pumps, because GM had good luck with it mixed with water on the hot air cars during testing. He also likes it because it is much cheaper. LOL Alcohol burns cooler and it takes a lot more compression to get the power, I believe. One of the problems is that it gives the 100 number when run on an octane test engine. Some will argue that since it is not gasoline it should not be given a measured octane number but should be given an octane equivalent number.... I think, theoretically, it is probably superior to ethanol; but, for the most part, it ain't worth the improvement, imo.  Did I hear you were working for a ricer company? |

Steve it took you almost a day to respond, what's going on?Actually, a fellow by the name of Smitty owned the refinery I was talking about but sold it years ago. The first year they added 10% Methanol to gasoline. It definetly caused some problems, screwed up injectors and pumps in lots of cars. The following year they switched to a mixture with 10% Ethanol. Your right about it being cheaper. I'll have to ask Smitty about the octane rating 130 & 115. But your right about the way they measure it. If 10% Ethanol ups the octane of 92 to 94.7 it must be higher than 100. Glad you brought this up, I'll see if I can get some answers for the number the Cheif Chemist came up with. I think I also found these octane ratings in one of my university chemistry books, so I'll have to look that up again. But your right Steve, Ethanol is definitely safer.  | |

but im useing now, from home depot denaturalize alcohol, is that what i should be useing?
