Intercooler Spraying, what say you?
I'm thinking about finding some sort of kit that will cool down my SMIC. I'm not too sure about nitrous as I'm not a fan of highly combustible gases floating around in our already too hot engine bay. Water doesn't seem like it'd do much considering it'd probably be at the ambient temperature. What about CO2 kits? Any downside there?

I wouldn't mess with spraying nitrous either, but only because it could get sucked in by my open element filters and lean out my combustion mixtures.
Spraying with ambient temperature water wouldn't be a bad idea. Water will absorb heat off of the IC fins and take heat away. Aiming the windshield washer sprays over the IC would work is seems pretty common.

You'd have to spray an incredibly dense concentration of NOx directly at your intakes in order of it to have any effect on your a/f ratios. By the time any NOx gets through the IC, it will have dispersed enough to be harmless.

spraying water is easy to set up and cheap to refill. just make sure you use 'clean' water, so mineral deposits won't clog the nozzles or pump. i use the water that gets filtered in my fridge to fill up a glass and dump it in whenever i can remember. i don't use it too often because it's in my daily driver and i don't usually need it, so i don't have to fill it up very often.

if you're doing this on the cheap, water spray is a good way to go. but BackyardSog has a point. if you do go with injection, make sure whatever system you put in has fail-safes!

I'm not heavily modded enough to warrant water injection. Later on down the road when I go single, that will definitely be in the mix, but for right now it's kind of overkill and a little more expensive than what I wanted to go with.

There have been a bunch of threads concerning CO2 sprayers but I am yet to see dyno numbers with a system off and then on. DEI claims nearly 50 hp increase on a turbo charged Honda. I don't know if the Honda was making 200 or 700 hp.
I have installed a full DEI system fuel/air/IC cooling on a GT40R FD. Some day the car may actually be done so I can find out if the thing was worth the trouble.

There was a thread recently discussing this. I'd really like to go ahead and do something like this, but it seems like it would be messy. Every time you run it, it would probably leave water marks all over your parts. Possibly even promote rust? I've been pondering the idea of a CO2 sprayer as well, but I'm worried about it being sucked into the intake... upon recent discoveries(by me) however, it seems as if the CO2 will dissipate by the time it reaches the intake, having no negative effect whatsoever. If you installed a heat shield in between the I/C and the intake, it would help even further. I'm very close to doing it...

I have an ASP medium SMIC. When you activate the sprayer, CO2 is all over the engine bay. I can not imagine ingesting that much CO2 would be good for performance. Having a base model, I dedicated the passenger side duct to bring the cool (non-CO2) air to the intake. I fitted an aluminum baffle to isolate the engine bay from the passenger duct and fitted a carbon fiber cone with attached duct work over the cone filter; an 11" K&N racing filter. What I did differently than others getting cold air from the nose is mine is 4" dia from start to finish and the cone filter sits on the turbo.
Keep in mind that I am yet to run this so I have no idea if it will work as I intend, although, unlike some of my other ideas, I can't see why it won't.
BTW, DEI warns you not to spray CO2 near your intake.

Water injection is the way to go.... even if you not heavily modded. Moderate levels of injection will be fine.
2 days of just lurking around the AI section of the forum and youl know everything youl need to know.
I suggest to you the Coolingmist products because of its design and pure simplicity or installation, use, and tuning. Their are other GREAT products, but this **** is just perffect for the "beginer".
Standard trunmount kit... everything already essembled..
http://coolingmist.com/detailmain.as...dardtrunkmount
VariCool Trunkmount kit... same as standard but with a controller for some easy but great tuning capabilites.... everything already essembled..
http://coolingmist.com/detailmain.as...=varicooltrunk
some installation instructions..

I have a bag style windshield washer reservoir with pump attached to a generic windshield washer nozzle. A master arm and a boost pressure switch (set to 4psi) to turn it on. ultimately i'm going to wire a manual button and get the light on my master arm to illuminate when the sprayer is on. But i'm lazy right now and i just have it "armed" and full.
I ran it at the track w/o thinking but no one knew. It doesn't spray a volume of water that would be noticed. I drilled a hole in to the plastic maybe 4-6 inches from the core. So that the water has no place to go but on to the core. The seal there between the plastic isn't great but it does stop a light fog of water.

With CO2, the worst that could happen is that if you sprayed while at a standstill for a long period of time, you'll run slightly rich because you've displaced some oxygen. Once moving, airflow will displace the CO2, plus much of it will settle out of the engine bay (CO2 is heavier than oxygen).

Ever hear of the "Cheater" marketed by DEI some time ago? It was designed to blow CO2 at the car next to and behind you. DEI technical group says it is a very bad idea to ingest the sprayed CO2 into the engine; more than negates the purpose of the system which is to increase hp. No one said it would hurt your engine but it certainly will not help performance.
