Edit: you could use the same switch to control the intercooler sprayer. Buy a SPDT switch and wire it as such:
- Low boost, no IC sprayer - Solenoid ON, IC sprayer OFF.
- High boost with IC sprayer - Solenoid OFF, IC sprayer ON.

Good luck and keep us posted. I wouldn't mind a very simple IC sprayer myself.

No, I agree that it is so much IC heat soak as it is total heat soak, so I'm looking to affect air flow as soon as possible after I'm rolling. I may also try reversing a naca duct on a carbon hood to try to get vaccuum to dray out engine bay heat, as well as increase air flow.

Honestly there isn't much required in the way of parts for a simple IC sprayer:
- Stock windshield washer bottle used as water tank $FREE
- ShurFlo 100psi 12VDC pump $80 (http://www.shurflo.com/pdf/industry/...00-543-138.pdf)
- Aquamist 4mm vinyl hose $2.75/meter
- Aquamist one-way check valve $14
- Aquamist nozzles (2) $16/each (http://www.aquamist.co.uk/sl/plist/pic2/jets/jets.html)
- Radio Shack switches, wire, relays, etc ~$25

I used two 911 window-washer nozzles (they're small and have two stainless steel adj tips each -4 nozzles total) and placed them on the bottom of the plastic intercooler baffle. Connect them to an existing Windshield washer line and the stock windshield washer bottle and pump is fine.
The only thing to buy is a pressure sensor swith to turn on the pump at whatever pressure you want.

Hi NZ,
Sorry for the late reply, but I am running around like crazy converting my Lambo Jalpa to a dual serial-parallel twin turbo (dsptt) configuration (also with port water injection, PWI, and intercooler spray).
Initially I did intend to offer a PWI system for sale, worked with Danno on this and made about 10 sets of the intercooler rail pictured, but I am now busy with too many other things to follow through with the PWI system, but certainly enjoy it on my own car.
For this reason I don’t mind selling you an IC spray rail for let’s say $45 and if you are interested, I can at cost provide you with the nozzles and fittings (1/8”NPT –> ¼” compression) as well. The pictures show the IC-spray rail just before and after the installation.
The “mist” nozzles, that I use, are from McMaster.com (look for P/N 378K81).

Sweet Laust! If you want to sell more...
People I suggest you get a Link H20 controller or a MAP pressure switch and do this! I will be dynoing the results in a few weeks... I expect at least 10WHP, and its engine stress free...
Laust, can you please advise how the rail is mounted? Also, does the rail include some of the flex metal tubing? I will order, just PM me the total and I will paypal you... I basically have the controller and a pump, I need everything else.

Doesn't get much simpler then an IC sprayer system.
Ehal: Best bang for the buck is a WI system.
IC Sprayer- $100-150 = 3-5% gain
WI- $250-300 = 15-20% gain (of course most of those gains are the ability to run more boost and timing) Only minimal gains from a cooler charge air on it's own.

IC Sprayer question:
For those '86 951 cars that already have headlight spray washers with stock hoses, nozzles, pump, and reservoir, why not simply move the nozzles to spray the IC?
The only downside that I can see is if the spray pattern is less optimal, due to lower pump pressure or inferior nozzles.
IC spray guys like Laust, et al, what say you?

For those of you that have already done an IC sprayer, do you think the factory headlight/windshield washer pump is adequate to spray the IC?
That would be the cheapest way to do it. You could either trigger it via a manual switch or via a boost switch or temp probe.
