Alcohol/Water Injection setup

[omnivore]

no...1989 Supra intercoolers...still alot of cooler to try to fit into an Omni in front of the rad, and still behind the grille,LOL

I've thought about adding a water/?? mix to my van too but I have a couple questions.
1. Since I have a blow through, I would wanna go after the intercooler so the pump would have to overcome 18-20 psi of boost wouldn't it? That would probably have to be a stronger pump than just a window washer one for me I think. Any cheap suggestions?
2. Wouldn't using some of the harsh chemies - like toulene, xylene and fuel, require a true fuel pump or something of that nature? Hmm, maybe a fuel pump would be the way to go, lots of psi and able to run the harsh stuff.

If you have a blow thru with an intercooler, I guess I'd be more likely to add a cold start injector to add more fuel and turn up the boost some more! The setup I have is basically a quick fix for a draw thru car until I get $$ to go for a T2 conversion. I would not feel comfortable
driving around with a storage tank of xylene/toulene under the hood...the flash point of that is too low to be living under there! A 30 percent mix of Denatured alcohol is not very flamable.

I have had my eye on this setup...

I was just on www.thedodgegarage.com and i KNOW i was reading on the about water/ aclh injection for a blow through system...

I'd recommend THIS H2O injection system. It's reasonably priced given its level of sophistication.

Be sure to click on the "Nozzles" page and watch the videos...

So placing the nozzle before the compressor and having the mixture sucked through the blades has no ill affects on the turbo, as opposed to putting it post compressor?

A great system can be found at: http://www.alkycontrol.com/ His system is alky compatible, allowing you to run methanol instead of H2O. :big grin:

From what I have read, the spray nozzle should be after the intercooler and as far away from the throttle body as possible so the mixture has a chance to turn into gas state before it enters the motor. Plus it gives it a little more room to cool the hot air down... <<<< Thats what I have read.

I see from your screen name that you have an '87 T1 car. This is just like mine, a 'log' intake draw thru setup. Unless you drilled into your intake manifold, I don't see how you could get the spray after the turbine.

I have run alcohol/water injection on my car for over two years with no problems. It is my daily driver. If your car is stock, except for a K&N, I'd go
to the exhaust system for a next upgrade. A full 2 1/2" cat back with a straight thru muffler will get you a LARGE power gain. :big grin:

[87caravelleT1]

Yeah i do have a log intake 87 caravelle T1...havent updated my profile in a while though and it now has a free flow muffler right after the down pipe and then dumped, and a boost controller set to 10psi...it is much faster but like you have done, I want to install a water injection system and appreciate you sharing your ideas and information with us. Im glad there have been no negative affects because i was hoping i could put it in prior to the compressor.

If you have exhaust work and a boost controller, it sounds like you are ready
to go. I used a 12v test light to probe around and find a 'key on' power source to use. It didn't take too long. I kept the hoses as short as possible
to reduce the 'lag time'. I set the pressure switch to 9lbs to head off any detonation. Running premium fuel (92 octane around here) I find I can run 13-14lbs boost on the street without problems. Adding race gas for the strip, I can go higher. Let me know how it goes!

You can build a blow through compatible system yourself for about $100-150 following the instructions at this site.

I have all the components for the system, but have yet to install it.

An extremely cheap and easy source for the "injection media" is blue windshield washer fluid! Its already a water/alcohol mix, and the detergents make your exhaust smell like candle wax! $1 a gallon goes a long way, and is available pre-mixed everywhere.

I just bought a brand new (old stock) Holley water injection kit for $26.95!!!! I will pick it up Friday and install Monday

Post some pics if you can. I'd like to see what it looks like!
