There's a 10 page post on tuners on water vs meth.. And the rep from devils own was in discussion. By the end he actually convinced himself that water/alcohol was a better choice.

I've always believed that if your just running a ton of boost and power on a built engine.. Where the engine isn't the limit , then meth is a better choice. It raises the octane level to suppress knock so you can run more timing and boost.

Water injection is more for running your engine past its limit. Eliminating knock so you can run way more boost and then tune for max power.

I think this is why people say max your tune out before you add meth. But with water.. You just add water and then raise boost and tune the car.

I'm more comfortable with water.. And I don't think I'll need more fuel any way. Not planning on making more then 32psi on my stock block.

I see a lot of pros quoting numbers similar to this. I used to run 11.5AFR with about 22* timing; the leaner tune with less timing seems to be making a LOT more power. Which makes perfect sense to me.[quote]


When you say you're targeting 12.3:1 AFR would that be on 94 oct pump?

Jay, love the write up. Great stuff!

This is becoming a great thread guys. Super helpful to me and I'll be referring back to it often I'd say.

I'm a little lost of the cooling property's meth vs water/meth... I have seen meth injection freeze components inside several vehicles, Never have i heard or seen of 50/50 doing this?

At end of day I'm thinking it's what performs best for someone and their vehicle(s) specific in question.

I myself and several guys out here run 94pump and pure meth in the tank as well. (stock long block subie trapped 125.1mph, only gtx3076r(36psi), exhaust, 1000cc injectors and wally 450 @ 2200ASL).


Ethanol always burns blue , if the flame is high enough it will get a yellow tail , Methanol either burns with an invisible flame or with a yellow flame depending on purity content


Most people switch to ethanol for the colder burning fuel factor, Correct? Methanol burns almost 50C COLDER then ethanol.

Now most won't see this benefit unless running a pure meth driven car, but benefits are still there to be had.

That and as mentioned in the tuners post..and a lot of what I've read.. Most won't experience the true benefits of meth unless fully tuned with 3d mapping.

Like I said before tho. I'm not that experienced in meth.. So I don't try to figure it out.

Now water is said to not get true benefits untill your way over the limits of your set up.. But I'm just using it as a secondary intercooler so to speak.

Jump to pages 10+ several people talk about 100% methanol spraying or e100. And how their results are, Some are saying you just need to adjust your nozzle size accordingly.

I understand the theory behind the water, but just from what i've experienced putting it in our tanks and injecting, and from what our drag car does. Pure meth to me trumpys a mixture IF SET UP PROPERLY.

if you don't do a proper 50/50 mix for meth at Minimum It's more prone to knock this is proven, Meth always needs to be the higher number, It will also require less fuel from your pumps.

people been injecting water into their engines for knock suppression way longer then meth.. It is proven to work really well. I went from some knock.. To no knock with 70% water.. And didn't need to change my tune.

So if there is too much pressure, the pump shuts off and so does the light.

Then I have a relay inline this circuit, that activates the idle switch pin. This switches to Aux maps.

So when egr turns on water injection. The fail safe wire activates the dash light and the aux map.

So if nozzle clogs. Light goes out.. Switches to base map..

Hose comes undone.. Light goes out Switches to base map

Run tank empty.. Light goes out Switches to base map.

So far it works well.. But I stripped the threads in my check valve so it's on hold till spring. I was running 7g nozzle .. 5 parts water 2 parts meth. Didn't seem to effect the a/f but dropped temps everywhere and eliminated knock at 25psi and 14°timing.


I like this. I am going to try and copy for next year. tongue

The pressure sensor I am using.. Is a a/c pressure switch from a Mazda or Nissan. Its about 35psi to switch on. The 92 talon has a 30psi switch.. But I was afraid of so was running 30psi of boost... Then it would activate if there was no meth pressure.

Why not put your pressure switch on the other side of the check valve? And your fuse should be between the battery and relay not after the relay.

I was worried that the check valve would hold pressure in the line too long and not switch into safe mode.

The sensor is the first thing treated into the nozzle. Its actually a brass T.

My check valve is actually about 18 inches of braided hose away from the nozzle.

And I figured the fuse should go closest to the pump it self. To protect it from anything else anywhere in the curcit.

Fair enough on the pressure switch that makes sense. But the fuse needs to be closest to the battery its to protect the battery from shorting and causing a fire not to protect the pump.

That would actually work And look better anyway. Tanks Stephen, I'll swap that around and just run one wire from the battery to a fuse block and run both relay 12v sources off the other side of the fuse block.
