Thats the air to water site, but if you go to the bottom the "back to page 1" link takes you to the air to air site. lots of good information. FYI straight water is better than water/antifreeze... as little as 23% antifreeze will hurt the exchange ability of a A/W ic system... didn't know that.
Picked up a rad/fan from an 80's honda motorcycle i'm going to install this weekend, along with pump/AFPR.
I'm going to put the motorcycle radiator in front of the A/C condensor, and plump the pump into the bed, along with about a 2 gallon alum storage tank I plan on welding up sunday while i'm off. also going to reuse my stock pump since it still works, and put a second smaller tank along side, probably incorperated into the same box, but with an insulating wall inbetween. i'll fill this with ice and salt water and run the coolant through a series of coils in this tank with the factory pump. that way the resivour stays cold, and it can push cold water into the system as needed.
sooo... from tank, to pump, to IC, to moto rad, down to stock CCHE, back to tank. also a second system, that only cools the resivour fluid as needed off of a switch, like at the track. going to insluate the tank so it'll (theoreticaly, hopefully) hold the ice a while if i'm not using it. def going to insulate both tanks pretty well also.
I know i'm going to get hella lot of "Go air to air it's better" responses to this so i'll explain my reasoning now. This is mainly a drag truck. yes it will be driven on the street most of it's life, but it's primary reason for existance is drag racing at the track or where ever. using this method, i can keep approx a 2 gallon reserve of near ice cold coolant virtually on demand. and cool the holding tank ONLY during the staging lanes or whatever via the second pump. I'm doing it like this because i see no reason to waste thermal energy cooling down the CCHE/intercooler body. once i'm on my way to the line, the I/C pump will start pushing near ice cold coolant through the I/C to suck out the heat from the compressed air, since the IC body (which will be wrapped as well as the exhaust turbine) does little to cool the charge even if it's in the sub zero temp range at the start, due to limited surface area/thermal properties. this way the entire pass will have been made with cold water due to the resivour. and while in the pits i can once again rechill ONLY the coolant in the resivour and not the IC and CCHE.
I'm going to put temp gauges inline after the pump, after the IC, and after the rad/CCHE and if the Rad/CCHE are doing little to no good cooling the water after the IC, i'll eliminate them and put a third pump on the tank just to push fluid through the CCHE's on the street. or Y them out while i'm at the track. how ever i also see a logical reason to have a seperate circuit for the CCHE's as well ( off of the tank anyways) this will keep the bulk of the fluid cold having a exchange area on the CCHE's larger than that of the internals of the IC, theoreticaly it will be able to remove heat faster than it's absorbed, and if the resivour is kept at or below ambiant, even normal street driving will be greatly rewarded.
PS, no it will NOT be cheaper to do an air to air, so far i've got ~50 bucks into a pump, and 50 into the extra rad/fan. i work at a fab shop, the alum is free, I just use the waste drops (which are still relatively large) and "scraps" of the 3/4" dessicant tank drain line. we need two solid 20 ft pieces, and there's regularly 10-15 ft pieces left on the roll that are left over unused, generaly thrown out or used for other odd projects. so show me a nice air to air setup for under 150 bucks (figure another 50 for tubing and misc. fittings), that can get the IAT's below ambiant temps and i'll entertain the idea...
