W/I use for intercooler spray

[mirkoelek]

Is it possible to Run second line from my Water injection output to spray my intercooler.
I think it would be an easy upgrade....

sure but the cooling effects would be fairly low, also you'd go through a tonne more water since you'd need a much larger nozzle to adequaetely spray your IC so make sure you have some kind of water level gauge.
But really, if you're gonna spray your IC, use Co2.

any one done a write up on this ? i was thinking baout using a 20oz tank froma paint ball gun but what would you open and close the tank with ? any info would be sweet thanks

I used the rear window washer line and just ran it up to the FMIC, with two universal spray nozzles from pepboys just for the summer and using straight water.

I run the dual output water/alch injection kit from enginerunup. I have the small jet plumbed into my lower intercooler piping right before the intercooler, and the big jet in the upper intercooler piping right after the blow off valve. The two injectors kick open at 7PSI, and push about 350cc of water.

Running 50/50 distilled water/alchohol on a stock sidemout, I can run 21PSI with no knock and no heat soak. My timing is retarded 1 degree from 4-8000 RPM using DSMLink. This is on an EVO III 16G. Before the water/alch injection, I could only run 16PSI on the EVO, and had to pull 5-8 degrees of timing because heat soak would creep up after two or three hard pulls.

Considering you already have the water injection setup, it might be worth it to plumb it in pre-intercooler. Some folks have advised against this, but you can't argue with the results. It would definately help your heat soaking a lot more than just spraying the outside of the intercooler. I know it did for me.

I was gonna say the same thing: don't waste the second nozzle outside the intercooler, spray after the turbo, before the intercooler. This should fight heat-soak very well. There's two-stage kits out there that use a second solenoid to control the second nozzle separately from the primary. There's also twin-nozzle kits that just give you the hardware to hook up a second nozzle before the IC. For your purposes you'll probably need a two-stage setup.

My plan is to run a big jet before the throttle body, and a small one before the intercooler. I'll kick in the small nozzle much earlier than the large one, maybe on a WOT signal, or a low boost signal. Maybe even wire it to a push-button as well, to activate it like an intercooler sprayer (this is what you want). This might cause the engine to bog if it's done at idle. Some experimentation is needed.

The reason I wouldn't run a huge jet before the IC is that there's a chance of the water/alcohol pooling up in the IC, which is not what you want, to say the least.

If anyone would know what should i do here ...I'm currently running single nozzle in the TB elbow and its M5 from engine runnup.... Should i get two smaller nozzles (m3 and m2) or should i run two M5's....
one at the current location (tb elbow) and second before IC

Please search this. It's a very old concept, does no harm but virtually no help. And, it tends to make a mess.

If it's not something you see everyone already doing, there's probably a good reason for it.
