Questions about h2o/meth inj kits

[TGP37]

I'll look that up.

Now that you mention it, I have a flare kit and lots of stainless steel line. I could build a system using brake line and fittings I have around the garage. That would be cool looking and handle pressure very well. Would be sturdy for sure.

My primary concern is detonation suppression, though temp reduction spraying into the compressor is tempting. But that takes a recirculation valve instead of BOV and the MAF pre-turbo. Making the IAT out of place either way. Or run SD.....

I only need roughly 120cc at onset and progress to 180cc injected. Triggering at 4-5psi and max at 12psi.

Which is 12% per fuel by weight. With a 5 gallon tank, a fill should last a while.


Not sure if I should pull timing or open a wg if the injection fails/runs dry.

Your welcome !! AleroB88 (Greg) has a write up for a meth injection system using parts gotten from Lowes and a few other places I cant remember if its on here or not but it is posted on GAGT with pics

Many thanks unchained, I was looking around and found Aquamist Injection systems. A bit pricey but wow they look nice. Noting they are the only PWM controlled injection system I can find.

What I thought was slick is the distribution manifolds and fittings. It would make a really cool looking install.



For a perfectionist, this is a nice product considering the accuracy of h20/meth injection ratio to fuel.

I just might consider a home brew using some parts from Aquamist. Heck, I'd use those distribution manifolds as boost/vac port for other apps.

Thanks, I'll look that up.

I wouldn't mind a used meth injection kit. Some things are just hellish expensive brand new......like a quality electronic boost control unit. GReddy Profec B is one I'm looking at. The more I can save, the more I can get

Forums like nasioc are great for for finding second hand universal turbo parts btw.

I got a used snow stage 3 kit for $360 shipped. I'll be trying it out soon and it can inject based on boost, injector pulse width, or both.

It supports dual nozzles if you buy the dual nozzle kit as well

Anyone suggest a specific boost cooler for these motors? I see Snow Performance and AEM have a GM MAF calc for progressive spray. I think the universal, top of the line kit is too much.....or is it worth the money?

Or am I better off getting a basic kit with boost reference and a steady injection rate across the boost range?


I want to spray before and after the turbo compressor. Which leads another question....will any of these kits support multiple injection or would that require a pump upgrade?


Knock suppression is a good thing on hyper pistons (yes, this is a non-forged piston turbo build)




I suppose I could just say, "anyone have any suggestions?"
