Is anyone on here familiar with water injection. And if so has anyone ever heard of the kit that www.snowperformance.net makes. Cause I'm really interested in getting the stage 2 kit with the variable controller. I've read alot about and couple of people I know with vipers have seen some great gains with it.

 

Check out www.devilsownonline.com. If you have a really fast spool getting a progressive kit is probably a waste of time. I made my own kit with a progressive controller from autospeed.com and it works great.

 

thanx for the link man I will be checking out there site too.

 

I've heard of the snow performance kit alot of mustang guys use it. I don't have any experience with WI though. I know a guy or two on here does. chris'smax has it I think.

 

I have a DIY kit, it has most of the same parts the other kits do. Either you need to be able to advance your ignition timing or add more boost to take advantage of the effects of WI. If you add water injection to an allready well tuned FI set up with out any power increasing changes, you will loose power.

mine works great, read up on coolingmist.com for info on the kit.

I run mine because i am running a 2.87 pulley w/ stock timming

 

There are a bunch of links in the stickies. The DIY kit that the GN guys have made is basically the same components that the other kits use. Read up. It will save you like $100.

 

Thanx for the info guys.

 

what exactly is it that water injection does?

 

supresses detonation

 

It also cools the air charge which results in more power at lower boost levels

 

You can use methanol (or denatured alcohol from Home Depot) to increase octane, so you can safely increase boost. Water does better as a cooling agent but cannot increase your octane.

 

someone told me about using rubbing alcohol mixed w/ water. Is it true you can use this mixture?

 

how much power could this yeld?

 

I think rubbing alc and water is ok. I use -40deg ww fluid with a 60psi shurflo cranked up as high as it will go, a 10gph and a 15gph nozzle. I have run 25psi with 22deg's advance with 91 octane. Without it I could only run 12 or so psi with 22 degs advance before getting audible knock. It works really well, especially if you have access to your timing/fuel maps.

 

Wow~! That's impressive...I knew it was good, but not 2x the boost good.

 

It doesn't really give you any power, it enables you to run more boost or timing without detonating. It might give a little power because of the cooler intake charge, but not much.

 

I trap lower if all remains the same and I run A/Wi.

 

There you have it. I didn't think it would add any power at all honestly but I've heard some people say the cooling effect does. Good to know for sure now that it actually takes power away if you don't bump timing or boost.

 

Yes, you can use isopropanol but that is the worse of the 3 "alcohols" you can use. Here's the best in descending order:
1) methanol
2) ethanol
3) rubbing alcohol

You can also use winshield washer fluid as Bernardd mentioned, but it will leave a residue and color the parts that it touches.

The Evo guys crank up the boost from 20.5 psi to anywhere between 25-30 psi on alky injection (the lower end is usually a mix of methanol/ethanol with water; the higher end is straight methanol). For the guys who can increase timing, they do that and crank up the boost just a tad. Increasing timing usually gives more power/torque than just cranking it up.

 

this is real interested ...... So you can run higher boost and timing and still wind up safer than tyring to push it on high boost. Wonder how much to put a kit together....Ballpark?

 

Try looking at the links posted in this thread...

 

I might just get one of these things. wonder if I may run 18psi and someheavy advaced timing.........Is it that good. my turbo might make somewhere around 360hp at 18psi stock ct26
