Water to Air IC - sr20??

[travypoo]

I have looked everywhere and there doesnt seem to be anyone running a water to air intercooler on an sr20. why is this? too expensive?? cooler intake temps and more boost dont interest anyone??

i think this might be the same one

they're not real practical for street use... judging by the size of that turbo that's probably a drag setup....which water is perfect for. fill it up with ice water and you'll have icy intake temps for a short time

but on the street u can't really run with a trunk full of ice water... and i suppose you could use engine coolant, but that shit's 190*+.... And you could run an Air-water cooler for the air-water IC...but then you might as well just run the air-air IC and be done with it

air-air is easiest for "normal" use. I suppose a water IC would be pretty good for drift. At least in competition where you're only gonna do a few short runs

EDIT: Holy hell I just noticed the fueling setup on that last SR. probably flows as much as a garden hose lol

i want to say that it gets about 1/2 mpg. lol

look into an mr2 w2a i/c. they run those all the time for street set ups.

Ya, the first thing I noticed was the fact that it had 8 injectors. I thought to myself "well my SR will certainly never need more than four" lol <-- I was going for a tuner Buzz Killington, could be better.

[travypoo]

can anyone tell me if any sort of tune will be needed to run a water to air (with ice)? a possible lean out? i couldnt see it, people drive air to air coolers during the winter. any help would be great thanks

[AJxr]

i dont think there would be many gains using an air to water over an air to air unless you are drag racing or in a full race setup.

but there is certainly no problems running the air to water in a daily street car, just something else to need tending to IMO.

[travypoo]

wouldnt a cooler intake charge be a gain? more boost and less chance of detonation

[96Turbo]

yes, cooler/denser air is always a good thing for internal combustion engines. This doesn't increase boost though....it ALLOWS you to run more boost without danger of detonation

while water has better thermal dissipation properties than air....you need some way to keep a supply of cool water going to your intercooler. this is how heat transfer works...you've got 2 different fluids at different temperatures. the "hot" intake air, and a "cool" fluid that must be cooler than the intake air in order for it to cool it down. so for a quarter mile drag racing run it's easy to keep the water cooler than the intake air because you can fill up the IC with ice water and it will stay cold for the minute that the car is running

but on the street where are you going to find a continuous source of cool water?? this is the problem with using it on the street. you either have to carry around a shit load of ice water with you, or cool the water with a heat exchanger....which is basically another intercooler run in parallel with the first. at this point you're better off using an Air-Air because the ambient air temp is pretty much always cooler than the intake air.

[travypoo]

the only reason i am really debating doing this is the car is a drift car, it gets driven on the street once or twice a week if that. i am looking to do something different and something effective. im going to be running an intake temp gauge and i would like to run both set ups and see the difference.

[landins13]

mr2's have serious overheating issues, the radiator is in the front of the car with coolant lines that run the full length of the car, water to air is def more effective in tighter spaces, they are also effective when you hook them up to a remote cooler with a small electric pump

what I would do is run an air-air IC with a water or CO2 sprayer on the IC. So for normal daily use you can run it like normal....and when you want a little extra boost/HP you just spray down the IC. There are some pretty cool electronic controllers that will regulate the sprayer too.

but it would be a good experiment to run both setups and measure the intake temps. specifically for prolonged use with the water setup.

[travypoo]

i would be running the water pump on a switch. i dont see why i couldnt run the pump only just before runs and make the ice last a good part of the day.

[travypoo]

you would also think these would be better for a drift application. while waiting in line your a2a gets heat soaked and your only doing 30 second runs which isnt really a whole lot of time to cool the a2a. its just going to stay hot all the time. where as a w2a you can run a switch and turn the pump on just before a run, and make your ice water last a decent amount of time. plus with a front rad and e fan i dont know how crazy hot it would even get. with the boshe 30GPH pump, i will be circulating the ice water in the tank roughly every 6 minutes....so during a drift event/practice i would be able to circulate the entire system every 10 to 12 runs on the track, with a switched water pumped. i dont think that the ice would melt after one full circulation. but i may be wrong.

Although some correct information has been said above, you guys have obviously not looked into this very deep. The guys who use water-air setups almost NEVER rely on a single sump. The way a kit would be done is simple. You have a separate radiator, with its own pumping system (usually a 12V bilge pump), that continuously circulates the water from the heat exchanger its self and back to the radiator. The heat is transferred into the water and then expelled through the radiator. Bottom line, a water - air setup is far more efficient. The complexity of the system, which its really not that complex, usually turns people away from wanting one. A typical air-air is easy to install, very universal, and looks pretty cool, so people just do that.

You can see, in the pictures that were posted, there are actually AN fittings for the water inlet and outlet lines

Here is a cool site that sells systems.

that black top looks crazy. 8 injectors and a big fucking turbo. it looks like the valve cover is welded down or something

[s14unimog]

It looks patched, its just sitting on the head.
