Water Meth

[Aren Jay]

So I was looking into this and it says under WOT that it injects the mixture, but under idle it uses just normal gas. How would this work with a higher octane tune and lower octane gas. It will under WOT raise the octane to 100+ when using 87 octane. But at idle it would only be 87 Octane?

Can a tune be setup to use this?

Water meth does not raise octane, it lowers IAT, allowing you you to run more timing, IE more RWHP, it does require a seperate tune, I am not a big fan of it for the simple reason what is going to happen at the track, if it fails??

Severl MM have gone boom running it. Why they went we do not know, but they went.

As stated above by Sailsmen - Meth was operating when several of our net members NEW forged engines blew. Some of these incidents have not even been made public for various reasons. No one really knows why these engines on the net or why several others on the Mustang boards have blown. It is a mystery even to highly regarded engine builders. Somehow even with the Meth working something failed, but it seems to be connected with WOT runs and the Meth injection????

I ran a water injection system on an 86 Crown Vic, 351W police package. It was mostly stock otherwise. I wasn't using it to get more power, though, just to keep the pistons clean. When I got rid of the car it had over 180k on it and still ran smooth. Before I put it on (at around 90k), it tended to ping and diesel after I shut it off. The water injection stopped both.
I only used distilled water in it. I didn't dirve it easy. I usually got it to the floor at least once every time I drove it (usually a lot more than once).

We are talking different type of engines - 10.0+ compression with SCs on them. Detonation is our biggest concern with Meth injection.

Understand. Totally different application.
I pulled the head off of a different car (many years ago) once that had a small coolant leak into one cylinder. The top of that piston was clean and shiny. The other pistons had almost a quarter inch of carbon build up on them. Water does a good job of keeping the carbon buildup from happening on a high mileage, low compression engine. I guess that was my point, but I didn't make it very good (one too many concussions...).

I run a Snow Methanol system. Had it for almost two years now.
I do NOT use it as a tuning aid for more power. It is only there to provide a measure of safety when under boost.
The issues some have with it is when it is relied on to run additional timing in the tune.

On the dyno, though it was good for an additional 10ftlbs.
I can run hard, park, pop the hood and lay my hands on my blower....nice and cool.
