Latent heat of evaporation:
Water: 2260kJ/kg Methanol: 1100kJ/kg And no I am not done yet with the other thread, it is a lot more to explain in that one vs this one. When Methanol gets combusted in the cylinder its sure not cooling it during this process :P |

Its impossible that water cools just as good or better than methanol.

I think the best is just do what you prefer, and if you wish to line up an equal build to equal build, one with water injection, one with straight meth, (in our general capacity of LS builds) then I will gladly wager you on the straight meth car to win, and I'm not much of a gambling man, I just have a lot of seat time with this in particular.
That said, if your not looking for more power, then yes I understand the physics behind the two. |

Cars certainly run cooler on e85/meth.

That said, if your not looking for more power, then yes I understand the physics behind the two. For a 100% fast road car, water can make a lot of sense. It's free, it works, it's available almost everywhere, and in terms of usage, it is more efficient by volume. And of course it is 99.9% safe. Even for a track, road course or whatever. ie any hard use longer than a few seconds. Water again would be more efficient, any volume would last longer. If you couldnt make 750-800rwhp using water/pump, then something is badly wrong. Certainly at that sort of level, methanol is not required IMO. Would methanol make the task easier ? Yes it probably would. But not 100% necessary. |
Everybody, just do what you like....some understand, some don't. This thread wasn't about hp numbers, but to some, that is all that matters.

Number's don't lie. By all means sir give your scientific response with data to back it up. Still waiting on your scientific response in the other thread surly you have finished moving by now.
So what your saying is that methanol itself dont actually cool the combustion chamber? If that's what your saying I don't think your correct. I suppose for now we will have to agree to disagree. :lol: just because you have 415 days a year that its 65 degrees and sunny with a 1% chance of sprinkles doesn't mean your right.. and btw.. when that 1% does happen.. you people go crazy... really.. its just WATER!!! |

Because of the difference in heat that is released from the combustion process vs gasoline. Same reason diesel run "cooler". It is not because the meth/e85 is taking OUT heat it is because it burns cooler.

I get my car tuned Friday. I have an Alky Control kit, and it will be a non-meth dependent tune, just for safety, single nozzle. So since not looking for extra power, and I think I will have plenty of fuel, should I have it tuned with water? If I have it tuned with meth, could I use water if I wanted to later without a retune, say if I ran out etc?

2 different arguments in here. If you are arguing about making the most power like Doug@ECS said meth only wins hands down. Now, add some water on top of that volume of meth, and you will have a setup even less prone to detonation if you were approaching the limits of the tune via boost, timing, etc. That's my experience. |

Just went back and read the first post. That was in the first post lol.oops |

and btw.. when that 1% does happen.. you people go crazy... really.. its just WATER!!! Guess ill just have to use my car for testing. Ill call julio tomorrow and order some different nozzles. I predict a 4-8 % power loss between 100% meth and a 50/50 mix. |
