Anybody Tried Water / Methanol injection ?

[Accordtheory]

I was trying to set up a system that had a dedicated pump, tank, injector, and injector controller, (pulse width of map vs rpm, the whole thing would basically be identical to a fuel system) but eventually said f it because I was too lazy to figure out a way to make it 100% failsafe. It would need to have pressure switches and pulse width monitoring, with the ability to trigger a boost cut upon failure to qualify for my definition of failsafe. I would hate to blow my engine because of something like that..that would be almost as bad as going lean because your tank was low and your pickup tube got starved halfway down the track..

be sure to always run distilled water, obviously, and let us know how it goes.. I guess this is becoming more popular with evo guys these days, but even with knock sensing, I don't know if I'd try very many of these systems on the market these days.. except maybe that aquamist system, which is very similar to what I wanted to build, programmable and if I remember correctly, over $1k..

I just bought a kit to try it, i was wondering if any of the other turbo accord guys have tried it yet (doubt it, but just wondering) im prolly gonna run either 50/50 denatured/water, or 50/50 meth/water

IIRC methanol is HIGHLY corrosive. I don't know anything about running a turbo, but I would make sure all the parts are compatible w/ methanol, you don't want to be leaking that stuff all over your car.

Peace.

the kit is 100% meth compatable. Im thinking it should allow hardcore timing maps while still on pump gas

in a simple explanation, what is methonal injecion anyways?

i'm considering the aquamist system in my N/A KA24E in my truck. i'm looking more at the economy side of it, not so much the performance side.

accord theory, what parts had you acquired for WI? while i'd love to start out with even a lower aquamist kit, i don't see it happening. if i can get the bulk of the parts in a "kit" from someone, i'd be far ahead of the game.

as far as injecting alcohol with the water, i would say avoid it. with a properly tuned engine, it's not going to add any performance.

one thing to remember, though. more water, less fuel. don't pull a vishnu tuning and add more fuel.

[AccordEpicenter]

they actually say the more methanol percentage you add into the water, the more performance gain you get, but the less knock resistance also. So if you ran straight water you would have the best knock resistance but maybe not the best performance, so a 50 50 mix seems to be the best compromise. Im gonna try putting some timing back in to run and not be soo conservative.

Note to self: A company will say their stuff works the best just to make a buck. For instance "The Tornado Fuel Saver." I hope everyone finally realizes what a load of crap that was. Just another thing to waste money on to make someone else richer off of the little people.

it is a method to drop the intake air temperature there by enabling you to run higher boost and advanced ignition timing without the worry of detonation. Dropping the intake air temperature enables denser air and better Air-fuel ratio and there by you make more power in the combination of more boost and ignition timing.

when you cannot reach maximum brake torque by advancing timing without first encountering the knock threshold, your octane is too low for the given combination..injecting h20/methanol artificially raises the octane by absorbing heat that would contribute to knock.

I thought they have real time mixture adjustment with two seperate tanks.

this thread was starting to be legit, then they had to go compile all this old shit together..I Hate when they do that..now people are going to have to sift through all kinds of bullshit to read any real info.. They should have just deleted the old thread.

I would just inject straight distilled h20..the power is in the tuning, not the small reduction in charge air temp with methanol vs h20's reduction in in cylinder temp..
I think if you get your a/f around 12:1 and can reach mbt without knock, you're all good..

[AccordEpicenter]

Exactly, you dont really see too much performance gain running just the water/alky, you get the performance gain from advancing your timing over what you could before because it cools the cylinders down preventing detonation, which race gas is more resistant to detonation over pump gas, so its like the next best thing to race gas.
