Myxalplyx Posted October 8, 2004 Share Posted October 8, 2004 Yeah, I know this has been asked a million times. I know there are pro's and con's to both. By a stroke of luck, I have both in my posession. The Air to Air intercooler I have is from a Ludespeed Stage II turbokit for my Impreza. I never got around to re-installing it and may never do it. It's an air/unit but I'm concerned about the airflow over the intercooler not being enough and it would just flow over it. I also have an air-water intercooler but no water tank to store the water in it. It's a 'Laminova' (sp?) unit. I purchased it in September of last year from ProECM.com (Dave there) with the intent on turbocharging the XT6 but my money ran dry and I dumped all the plans. So it sat in my garage. If you have any air/water intercooler experience, please fill me in on how I'd have to approach this because I'm clueless. I already have the intercooler, water pump, and 'heat exchanger' with clamps and such. I know I need a water/mix solution tank, intake-turbo, turbo-intercooler and intercooler to throttle body fabrication. Plus, where would I get the tank to hold the water? Thanks for any help and tips. This all would go on an RX turbo I purchased earlier this week. Link to comment Share on other sites More sharing options...
TheSubaruJunkie Posted October 8, 2004 Share Posted October 8, 2004 The tank shouldnt need to be special. A large windshield washer fluid resivoir would probably work. I had a AWIC in my possesion from a JDM EJ22T. I had the pump and radiator, but the radiator was too small. Would have needed 2 of them. At high speeds your A-A I/C will be best. Expecially with a scoop and plenty of airflow. If you wanna hide the IC and have efficient cooling at high and low speeds, i would use the A-W I/C. -Brian Link to comment Share on other sites More sharing options...
oddcomp Posted October 8, 2004 Share Posted October 8, 2004 junkie forgets the usefullness of being able to add ice to the awic for those "special " occasions hehe and you can use oil cooler/tranny coolers ganged up to cool down the water also the larger the water tank the more time you have before the water temp gets hi enough to be usless as a cooling medium short blasts and and such it should do just fine long hard pulls with out enough cooling for the water itself then it becomes useless i f i had a awic i would add a fan to at least one of teh radiators to help with lowspeed cooling/idle cooling to get the water temps back down faster when it was off boost ect hmm someone needs to write a prooggie for usmb just to decode my typing skills...

TheSubaruJunkie Posted October 8, 2004 Share Posted October 8, 2004 Air temps shouldnt really get that high, but an adiquate radiator will be needed. Your AWIC seems pretty small, so i dont know how that will effect things. If you mount your radiator in the front of the car, it oughta get enough airflow to cool the water just fine. The water isnt going to reach temps of 200degree's like our engines. -Brian Link to comment Share on other sites More sharing options...
oddcomp Posted October 8, 2004 Share Posted October 8, 2004 well.. with out intercooling my air intake temps max at 220-ish f at 10 psi.. so if he kept on the boost long enough with out enough cooling surface for the water.. well you can see where i am going Link to comment Share on other sites More sharing options...
rallyruss Posted October 8, 2004 Share Posted October 8, 2004 if you are concerned about air flow you may want to make up some flexible ducting to help seal between you scoop and the hood. my current IC sits right at he hood opening level with some rubberpieces to seal it while the hood is closed. this will all change by next week when my new IC gets here:brow: . as for wich one to use? practicaly speaking the air to air IC is going to fit and be a rather straight forward install once you get it plumed properly. but that would be really cool to see a air to water intercooler instalation done right. that thing would have great off the line performance. as for the tank question. It would look really nice if you could find a nice tig welded aluminum or stainless one. and while I am spending you money. how about running the cooling lines to the front of the car and thru a heatercore mounted in front of the radiator? I just changed one on a Taurus the other day and was tring to think of other uses for it. but I guess thats would be the job of the "radiator thingy" as you say. ok I guess Im not much help so I will stop now.

Xt6turbo Posted October 8, 2004 Share Posted October 8, 2004 The intercooler Kevin has is utilizing Laminova intercooler tubes. These tubes makes it possible to extract 2.5 time more energy (heat) than a bar/plate unit of the same size. The water temperature is of course dependant on the front heat exchanger. How big it is and how much cold air that flows through it. Our testing have shown that that intercooler is capable of taking out over 200 f out of the intake air. On the mini cooper kit we just finished, we see no more than 25f increase in inlet temperature from standing still to redline in 5'th gear, which is in excess of 100mph. The stock intercooler was showing 165f out, while ours showed <120 at the end of the test. So to say that an Air-air unit is better at higher speed is not correct when it comes to our intercoolers. Traditionally I would I agree. But that is for air/water intercoolers that are constructed around encasing an air/air unit. We have a completely different approach.

rallyruss Posted October 8, 2004 Share Posted October 8, 2004 200DEG temp drop!! dam. thats rather good. pressure drop is reasonable I assume? yeah I am going to get a big ol tat that says noboby listens to Russ:lol: ok no Im not. Link to comment Share on other sites More sharing options...
Xt6turbo Posted October 8, 2004 Share Posted October 8, 2004 200DEG temp drop!! dam. thats rather good. pressure drop is reasonable I assume? yeah I am going to get a big ol tat that says noboby listens to Russ:lol: ok no Im not. The intercooler flows 30% better than the stock WRX intercooler, so yes, the pressure drop is very reasonable. /David Link to comment Share on other sites More sharing options...
jspecscort Posted December 25, 2004 Share Posted December 25, 2004 im looking for a air to water out of a subaru does any one know where i can get one or what year subaru i need to look for? Link to comment Share on other sites More sharing options...
TheSubaruJunkie Posted December 25, 2004 Share Posted December 25, 2004 They were offered in JDM Subaru Legacy turbo's from 1991 to 1994 I believe. -Brian Link to comment Share on other sites More sharing options...
sportsterbrat Posted December 25, 2004 Share Posted December 25, 2004 The air to water I would think would be better in tight areas also isn't it better to keep the pluming as short as you can to pervent lag? Just rumbling.. Link to comment Share on other sites More sharing options...
BobBrumby Posted December 25, 2004 Share Posted December 25, 2004 yeh any volume of space you can get rid of between the turbo and the engine inlet will decrease lag. Link to comment Share on other sites More sharing options...
WJM Posted December 25, 2004 Share Posted December 25, 2004 http://www.netcomuk.co.uk/~gavinp/airwater.htm I personally favor the AWIC over the AAIC...why? Just cuz. AA is easery/cheaper install and such...plus more 'bling' depending on application. The AW you can add/keep ALOT of stealthness...aka...a stock appearance, no hood scoops and such...and it does seem to be alot more efficient.

jspecscort Posted December 26, 2004 Share Posted December 26, 2004 Don't mind me! I'm posting this picture for future reference. this only makes sense you want to draw directly out of the resivour as to get a little cooler water so you dont burn up your pump .. you could also use the cooler ive seen b/m i think makes it . it has to inlets and two outlets its made so you can use on cooler for engine oil and tranny oil.

tizzle Posted December 26, 2004 Share Posted December 26, 2004 Kevin, don't you have a air water intercooler sitting around? Link to comment Share on other sites More sharing options...
Myxalplyx Posted December 26, 2004 Author Share Posted December 26, 2004 Kevin, don't you have a air water intercooler sitting around?Yeah, I'm going to try and use it on an XT6. A picture of the air/water intercooler is on the first page of this thread (on the right hand side). It'll fail (Mr. Pessimist) but I'm going to try. I'll be playing with the AWD XT6 after I get situated with the Techworks install on the RX. Link to comment Share on other sites More sharing options...
WJM Posted December 26, 2004 Share Posted December 26, 2004 so you are going to turbo one of the XT6's? Link to comment Share on other sites More sharing options...
Myxalplyx Posted December 26, 2004 Author Share Posted December 26, 2004 so you are going to turbo one of the XT6's?I'll try....using some random pieces hanging around my garage. Nothing new! It'll probably be a VERY long project though. I sent my XT6 to a shop to get it done (Rallispec) before but now I'm going to try to go through the pains of doing it homemade. I don't have a load of $$$ to be spending on this. I'll be *&%$ for many months to come, I know. Link to comment Share on other sites More sharing options...
