Water/Methanol Injection
 

I am looking for experience and opinions on the use of Water/Methanol Injection as an alternative to intercooling for a super charger application.

I have run across this company Coolingmist which seems to have an interesting product.

It certainly looks like more trouble to deal with on an ongoing basis than intercooling but it is small and less expensive and seems to be fairly effective.

Works great. I used it on the yellow Procharged 540 and my friends Procharged 406, both pump gas and no intercooler. I've also used them on my Lightning and twin turbo GTO which were intercooled. Still allowed more boost and timing on pump gas which was more power.

I've used the following kits which worked well:

I run a progressive controller from Julio Don, but the Devil's Own controller is very nice... and he's taken the time to spec out the best pumps for the job.

If you set it up right it's basically maintenance-free (besides adding water as needed) as long as you use distilled water and have a filter before the pump to keep junk out of the nozzle(s).

Does it work? You bet. When datalogging my car, my intake air temp *drops* as boost increases; from 3 psi (water injection turn on point) up to redline (15psi) the IAT steadily drops because of the water injection. I'm going to keep the water injection even after I add an intercooler for the detonation supressing & cleaning effects, I'll probably just drop down on the nozzle sizes since I won't be relying on it to cool the intake temps so much.

Running water/methanol mix will yield more power but then you need to keep in mind methanol is corrosive to aluminum. I run water only for just that reason, it still provides the cooling effect and as an added bonus your intake runners, valves, and combustion chambers stay very clean from the steam. I'd much rather sacrifice a little bit of power compared to rotting out my .065" wall aluminum pipes from the SC to the throttle body.

I thought you could run that "de-ice" washer fluid in them? Then again, maybe that's methenol, I'm not sure.

that is a mixture of methanol and water, so it can be run. The first two I did were straight water and worked very well. The last two have been ethanol which gives extra fueling, an octane boost, and not as corrosive as methanol. Denatured alcohol is what it's usually called. Only disadvantage is it's more expensive than methanol, but it was only costing me $1.50 or so per tank of gas, so the cost was pretty much a non-factor.

Thanks for the input. This was quite helpful. I just don't see anyone on these boards talking about this technology but it seems like a very viable way to go.

I use a small setup on my supercharged 4Runner (a 93 with a 98 3.4 in it). Works great, allows more timing and boost... not that I really need it.

look at Snow's injection units; they're quite excellent

Thanks. I will check it out.

I use FJO's units.....great product.....
