fl327 Posted July 20, 2002 Share Posted July 20, 2002 anyone try to run a set of spray nozzles over their intercooler to run more boost? i was reading sport compact car and they talk about setting a system up on their rally focus, and ive known that lancers and jdm imprezzas run this setup on their cars from the factory, im putting an l28et car and in the future want to push large psi through it, and just wondering what people have done liek this, just thinking out loud i guess.

Dan Juday Posted July 20, 2002 Share Posted July 20, 2002 Evaprative cooling. Works great. Won't do you any good in SF though. Humidity is too high there. Only really works well when the air is dry. Head for the desert Len! Quote Link to comment Share on other sites More sharing options...
ratedZ Posted July 20, 2002 Share Posted July 20, 2002 hmmmm....maybe I should look more into this then since I live on hell lol . Doug's highly modified 280zxt turbo 2plus2 has this set up. Anyone have the link? Quote Link to comment Share on other sites More sharing options...
Tony240ZT Posted July 20, 2002 Share Posted July 20, 2002 If someone has a home made kit I'd be interested in what you used to get it working well. I know there are some kits, but I think it could be done for far less money, and the aluminum welded tanks are a little over doing it for just holding water and a vacuum. Do these systems use pumps, or do they just use the boost presure to inject the water? Are there cheap mechanical or electrical vacuum switches out there? I guess a waste gate could be used as a mechanical arm/lever to open and close something usefull. Quote Link to comment Share on other sites More sharing options...
fl327 Posted July 20, 2002 Author Share Posted July 20, 2002 i guess on this side of town i dont need anything like that, but for some reason at the track its always at least 90, i could see it work well there. they use pumps from an rv store with rubber hose to some nozzles to make the water mist, hooked up to a simple switch and the water supply they use a eight gallon summit fuel cell, but i could see using a rather large windshield wiper resevoir or overflow tank instead from a big car like a suburban or something, you would have to fill it more often but thats no big deal, i have heard that with the water injection you can squeeze a few more ponies by using windshield wiper fluid-it contains alcohol in it and helps marginally.

Make sure you head for the desert in a few months though, its monsoon like weather now and muggy here, won't help you here either now... We're using refrig cooling at the moment, but being the great a/c guy he is, Dan is correct when its dry we see at least a 20 deg cooling from evap coolers.

Lockjaw Posted July 20, 2002 Share Posted July 20, 2002 If you mixed some isopropl alcohol with your water, it would evaporate. Have to have a good sealed res for the fluid though. Quote Link to comment Share on other sites More sharing options...
Scottie-GNZ Posted July 20, 2002 Share Posted July 20, 2002 Be very careful here Most Z folks looking to do this are going to try and do it on the cheap and as Lockjaw stated, it must evaporate on the I/C!!! If you install one that does not evaporate, you are going to have water dripping right in the path of your rear wheels. This is why most drag racing sanctions dislike them.

SHANE Posted July 20, 2002 Share Posted July 20, 2002 why not try the NX kit. they use a spray bar over the intercooler and it sprays nitrous to cool it. shane Quote Link to comment Share on other sites More sharing options...
Cody 82 ZXT Posted July 20, 2002 Share Posted July 20, 2002 I thought NX was spraying Co2 instead of NO2. seems like that would be cheaper and still give you similar results. Quote Link to comment Share on other sites More sharing options...
BLKMGK Posted July 21, 2002 Share Posted July 21, 2002 There's an Aussie automotive site with terrific info, much of it requiring a subscription, that did some terrific testing of this. That article isn't a subscriber page if I could just remember the danged name of the site Someone help me out - they also did an AWESOME series on manual boost controllers.... You'll find that the sprayer doesn't work quite like you expect it too BTW. The intercooler is as much heatsink as it is air radiator....

Scottie-GNZ Posted July 21, 2002 Share Posted July 21, 2002 In a street car, an I/C sprayer is a quick-fix for an inefficient I/C. If the I/C is not efficient enough to cool the charge, it most likely is also inefficient in the flow. Rally cars need might need them because they are at full boost for long periods and the elements they race in sometimes cause the fins to become clogged. If you are looking to push a lot of boost, the I/C is a pay-me-now or pay-me-later affair. Pay up front for the efficient I/C you need or go for a cheapie then pay again to have it upgraded or for add-ons like being discussed here. An I/C has to be efficient at flow AND getting rid of heat. An I/C built to be efficient at one is more likely to be good at the other also.

fl327 Posted July 21, 2002 Author Share Posted July 21, 2002 hey anyone know about the nx n-tercooler, now that looks like it will bring some pain. Quote Link to comment Share on other sites More sharing options...
BLKMGK Posted July 22, 2002 Share Posted July 22, 2002 NX system? Well, back to back runs on a ProCharged Mustang resulted in NO difference in power. Mind you they didn't use the actual NX kit they simply took a nearly empty Nitrous bottle and hosed the intercooler down till it was icy. Power differences in that car were negligable and the owner of the car decided that purchasing the NX kit would be a waste of money. YMMV!

Guest Anonymous Posted July 22, 2002 Share Posted July 22, 2002 So Scottie, is it fair to say that a top-notch i/c like Spearco running in to the 70-80% will not see any significant efficiency increase or heat dissapation in only mildly humid weather? -980mak Quote Link to comment Share on other sites More sharing options...
