I broke down and ordered a kit, along with some accessories for it: http://coolingmist.com/detailpage.aspx?pid=02

I'm not sure yet if I'm going to run water/methanol or just straight water. Water/methanol has a power benefit, but pure water provides the best detonation protection, so I've read. I'm going to place the nozzle before the throttle body, facing the air stream. This is going to be fun :D

shark, who continually risks his car so you don't have to.

 

what size water tank are you planning on using

 

2.5 quart. I'll upgrade if I decide I need a larger one.

 

I'm un the market for a JRSC also. Did you get a new one or used? I want one but cannot afford 5grand (Canadian) for it.

 

how the hell does water injection work? wouldnt that be like intentionally attempting to hydrolock your engine?

EDIT: yes i get that its supposed to evaporate but still. i wouldnt trust it.

 

I don't think they spray that much water at once to actually hydrolock the engine. I'm not exactly sure as I don't have one but it can't be that bad for your engine. Im sure it evaporates fast enough to not wreck anything. I guess we'll find out when Sharkcohen installs and uses it.

 

ROFL, water injection has been used on engines since the 1930s. Hydrolock occurs when you draw in a column of water rather than air. The danger in my case is that this could possibly damage the coating on the rotors of my blower, but I'm taking the risk anyway. I wouldn't be the first to use water injection pre blower, it's been done before.

I should be able to run much less boost timing retard with this, we'll see how it goes.

I bought mine new several years ago.

 

Shark...thats not bad, price wise. I want one

I can't imagine how water only (no methonal) would do any harm to the coating. Heck, it appears that the coating comes off on its own anyways, based on what I've seen/heard.

Well I think Im going to look for a used one. You know of anywhere to look for one?

 

They pop up used on http://www.preludeonline.com occassionally. There is a small annual membership fee, but it's worth it for the amount of prelude informatoin that is there.

Why the coating comes off for some people is a mystery to me. My rotors looked perfectly fine after 20k miles. We'll see how the coating does after this.

 

Very interested to see your intake temps after the kit, be sure to post after!

 

Cant you also use alcohol?

I'd be wary of any reading the IAT sensor provides after this, it certainly wouldn't be a reliable reading of the incoming air. Nonetheless, I will post up what it reads, for kicks.

Yes, you can. I'm probably going to run 50/50 water/methanol.

 

I have also purchased a pump upgrade kit that will up the water pressure from 100 psi to 150 psi.

 

Is methanol readily available? Where would you buy it, and what's the cost? I'm starting to talk myself into this idea, since an IC is out of the question for us JRSC people.

 

Many washer fluids are just 50/50 water/methanol. Just make sure you don't get washer fluid that has soap in it.

Mine's coming in a week, let me try it out before you run out and buy one.

 

seems like a pretty basic kit, i looked on the website and didn't see what size the injection nozzle is , im assuming you have obviously taken into accound the raise in line press will change the amount of water injected..

and shakes, water injection is SOOOOO old, like shark said they have been doing it since like the 30s..

also i recently read a very interesting article about the combution process and the different stages and how very important water is in the later stages of combution..

the idea is that in the begining as the water is injected as it evaporates it "uses" up some of the heat in charge, the cooling effect becomes even greater when you add meth to it..

shark what made you decide to do pre charger injection?

Yes, I did take that into account. Based on their recommendations, my needs seemed to be in between nozzle sizes, so I got the lower size and am going to up the pressure. 2.3 GPH nozzle @ 100 psi, then I'll be bumping it to 150 psi.

There is no place to put it post blower on the H22 kit.

so i guess drilling and tapping is out of the question eh? or is there REALLY no where to drill and tap for the injection nozzle?

No where at all where you could get even distribution to all the cylinders.

man that blows, (pun not intended) lol

any more information on the coating on the rotors?

Magnuson, which is Eaton's official US remanufacturer, told me that this could cause the coating to flake off, but that it would only affect noise and have little impact on performance.
