The PFC and the stock ECU will not see timely/noticeable temperatures changes from chilling the intercooler down...the stock temperature sensor does not react fast enough. Based on it's location and it's physical limitations.

 

Garfinkle put an electric fan behind his IC with a switch under the steering column.he turns it on in traffic

 

I'd think that releasing CO2 in your engine bay would create an environment that's higher than normal in CO2 content. Unless you have ducting for your intake-I could see some problems.

Yes, please shoot down that idea for O2. Won't work, and most likely economically unfeasible.

Why not just compressed air? Don't try to isolate any gases, just pressurize the stuff. Refilling the tank all the time will get old quick, though.

 

Question: In all your posts, Duboisr, you mention "garfinkle does this" or "garfinkle did that". Who is garfinkle, because I can not find him on the forum and he seem to know what he's doing.

Also, Rich (goodfella) did the same thing with the fan behind to pull air through the intercooler which is definatly a step I want to take

 

Yes i would have to agree about not using CO2.. Think about it. What ever you spray onto the IC unless it evoperates is going to go into the turbos.. Well CO2 is not very for combustion. And like mastacow said, anything that has to be refilled is going to go old very quick.

 

I don't know, it is cold though! I use it to push my homebrew beer through the taps.

 

I did this when I had the stock IC a while back. just using the Washer pump and a nozzle I got at napa. When I dynoed it it was worth 8hp and 5 ftlb of TQ but only on the second turbo. But for 5bucks it was worth it.

 

are you going to try and purge that bitch ?

 

Don't quote me on this, but I believe water has better heat exchanging properties than CO2. The gas would frost the intercooler, but that will quickly disappear due to the heat of the engine bay. Water on the other hand will take the heat from the intercooler, and cool down from air passing through the system. It's not like the water is evaporating right away...

Also I don't believe you'll add as much weight using the rear wiper reservoir...

 

Alcohol evaporates quickly, meaning that not only does it not get on much in the engine compartment, but it will do a good job of exchanging heat.

Pour some on your hand and blow on it...same kind of effect that will take place on the IC. Noticeably cooler, huh?

Since passing stuff through the IC core via the fins won't affect any combustion gasses, I'd say it'd be safe to use a water/alcohol mix with no ill effects. The only unknown with this is how far back it'll travel once it's through the IC. Also, remember that you'll need air flowing through the IC for any of this to be worthwhile. If you're simply sitting in traffic, the liquid will just squirt onto the IC and drip off. If you have a fan, I'd be worried about that since you're forcing air through and might short out the fan itself.

When I get another IC I'll probably mount a fan on it just for those situations when I'm not moving, and can't see much value in a misting system for it. There's got to be a thermodynamics engineer in here to tell us how smart/stupid this idea is in terms of efficiency, etc!!

If it were up to me, and for my FD it is, I wouldn't bother wasting the time/money on something like this when it would likely be better spent on a bigger IC or a fan for the one that's already there. *shrug*

I'm still curious to see what happens though

 

Yup... ever seen how quicky isoprophyl alcohol evaporates? I used to use 100% IPA to clean my glasses, and it would evaporate in a matter of seconds(I'm not sure if that was party due to laminar flow). To be honest I wonder about the vapors... I'm too lazy to look at a MSDS and see the flashpoint(if any) of the vapors.

Unless you're venting it out it may present a problem. Ever substance has a flashpoint, but I seriously doubt the heat from a FD would cause the vapors to explode.

Comparing CO2 vs IPA/H20(or just water alone) I believe water wins hands down.

With a SMIC I think you would still see gains from any sort of injection system. It's all about making the intercooler as efficent as a front mount system without pressure drop correct?

 

Found the receipt for the nozzles i bought from McMaster Carr:

part number desc
3178 K74 2.53 GPH @ 40psi
3178 K61 0.63 GPH @ 40psi
3178 K77 9.49 GPH @ 40psi

I think I ended up going with the middle flowing one. One was a super fine mist, and the other shot too much water, I thought. These were like $3 each.

yer wasting your time messing with that stock iC...save your effort, time and money and get the upgrade...your car will thank you for it...trust me on that.

SO will your turbos....currently working an extra two lbs harder just to make boost if you are on the stock IC.

I don't think you should have any problems with it. Just as long as you keep it clean.

 

guys nx makes a kit like this for intercoolers, it comes with a 5lb bottle and everything needed to make this work, u can fill it with either nitrous or co2 http://www.v6power.net/ubb/ultimateb...&f=27&t=000894 here is a link for the product

 

If you just strap that kit on your car, the first time you spray under WOT you are going to go sooo lean you'll probably blow your engine...TRUST ME on this one!!!

It will take a bit more finesse than just bolting the NX kit to your car and pumping some N2O or CO2...
