snow performance and others(methanol inj)

[sporter]

Hey guys...anyone running or know of anyone running methanol inj on there supercharger or turboed Mustang?
I am looking into running one,they have great reviews but I know how that goes.

[PureVenom]

I know of someone local that was running it before he sold his car. I will have to look up some info that has been reported about meth injection on cobras in that it doesn't really help out much...like 2-3 hp gains were observed and documented.

Someone once said something to me that really makes a lot of sense. methanol injection injects water...water doesn't burn...so why would you really want to inject water?

That really stuck with me.

A better idea would be to run a small shot of nitrous to keep the intake temps down...but then again, that could require higher octane to do depending on teh shot.

Actually methonal does burn , it has a %% of achoal in it.I work on the Service rigs on the Alberta oil patch and we use it all the time for air lines our BOPs anything that has water contact it to keep the water from freezeing , and it burns clear , u cant really see it but i light some on fire this past winter trying to unfreeze on of our belly jacks.

but for 1-2 hp I aint even gonna bother.
thanks

I've seen SEVERAL accounts where there are 20-30 hp increases and higher on supercharged applications... I'll just have to find them



*edit* Here is one. http://www.alternativeauto.com/water...rbox_main.html

Another with 78 hp gain Snow Performance water/methanol boost cooler

Better burn more power.

I've heard reports all over the spectrum from 0 gain, to 20 gain, to loss of power because it is methanol mixed with water...not pure methanol.

I'm too whipped to look up what I have read on it,...I will get the links in the next couple days.

my friend has a 06 gto with a magnuson sc, he went to kartech in nj to get it tuned with the snow. the people there stated that cars would dino lower with it for some reason. he was running 50/50 mix.

It's really simple, cold air is denser, with denser air you can add more fuel. H20/Meth injection creates colder intake temps.

Exactly.

Ok...finally dug it up...here is what has been experienced in the real world with meth injection...


Meth results summary thread - ModularFords.com

the lure of meth.........

seriously though. alot of dsm guys use it in lieu of nitrous because of its ability to cool intake temps without increasing oxygen count. this means they can run more timing, or leaner fuel curves, or more boost. with nitrous, you have to add fuel to richen the mixture, or else you can run lean, which is definately not what you want to be doing.

the gains are not from the methanol or whatever you inject, the gains are from what you do afterwards with your added ability to reduce knock/predetonation from occuring.

Well If the DMS guys do it !!! then there is no futher need for any more posting on this subject

That's true...and then when you bring the DSM guys into it...man...it is really /thread time there.

[Thomas91169]

lol ill give you a /thread

[rocknbronco]

Hmmm if DSM is doing it then we should!!!!!

Quote: Adding meth only adds power if you are losing power as a result of timing retarded due to heat or detonation. Turbo cars with higher than stock boost and knock sensors can see big gains as a result of the lower intake temps and the knock reduction. Spraying meth in an '03 Cobra gives you an extra safety margin by reducing IAT2 temps, helping to cool the blower, taking some of the stress off the rest of the cooling system, increasing delivered fuel and increasing the effective octane in the air fuel charge. It's a cheap fix if you're pushing your fuel system or cooling system and refilling is cheaper than race gas. On its own, with the same timing curves and total A/F ratio, meth should decrease horsepower by reducing the burn rate in the cylinder and lowering cylinder temperatures and pressures. If you had intake air temps resulting in a few degrees of timing being taken away plus a knock sensor begging for even more relief, meth or water injection can produce huge results by eliminating those timing retards.

You can't just throw on meth injection and expect gains. It's not nitrous. You have to tune the car with the meth injection and increase boost and/or timing to show gains. It allows you to run that because it cools intake charges to allow you run more of said things .

To get the best performance everything has to be tuned even nitrous.

[bullitt482]

But adding nitrous to a stock tune still adds power, where as with meth you have to tune around the meth to gain power, since it changes the parameters in which the engine can perform .
