New AWIC Work
Well I'm going to try and upgrade the radiator in my AWIC setup.
I pulled the bumper off. I'm probably going to notch the bumper beam about 1.5-2 inches. However I want to see what radiator I'm going to use first. The vertical radiator core support is in the way....but I'm not sure if that will be a big deal. I need to start looking at different radiators.
Also, I found that my bumper beam was barely bolted on. The shop that did the work when I had a small accident messed up the bumper beam. The welds on the nuts broke, and he had them just screwed into the metal. So I'll have to fix that too.
Here's some pics

I have a the factory radiator, and my idea was to notch the bumper beam as well. It should work just fine.

Do you have any pictures of the stock AWIC radiator? If not, could you take some?
Thanks

What about mounting two smaller ones in the lower bumper in front of the wheels. There's a set of blocked out cooling holes under the blinkers that could aid cooling in that position.

ehh....I guess that's a possibility....but I don't think that would be optimal....plus require more hoses and crap.

It looks like you have plenty of surface area with the two radiators you have. Are they not enough? It also looks like you are running them in parallel rather than series. Wouldn't they work better in series?
I just located a good awic and am going to be looking for all the stuff to get the system up and running. Yours looks good so I was wondering why you were looking to change things.

I think he is worried/thinking about flow characteristics. A properly sized single unit usually posses less resistance to flow and cooling than multiple undersized units installed, regardless of piping arrangement.Jefferson wrote:I just located a good awic and am going to be looking for all the stuff to get the system up and running.

Jeff,
The setup I have does work. When it's cool, the AWIC is cool to the touch. The colder the weather, the more impressed I am with the AWIC setup.
The pump I have flows a pretty decent amount. However having a small fitting size 3/8" really restricts the flow.
This post shows the different flow rates with varying size tubing & radiators
http://bbs.legacycentral.org/viewtopic. ... 846#143846
I would like to find a radiator that has 5/8 - 3/4" fittings so the flow will be better.
I've also contemplated redoing the mounting for my pump. I don't like the fact that the pump is upside down, and also would like to have a small resevoir or surge tank right before the suction of the pump. I've got an idea in my head about that, but I need to see if I'll have room, and would need to do some fabrication.

I put a pc 680 battery in mine for the lighter weight, but now I am thinking that I can use some of the room I now have there for a small tank.
I haven't got my awic yet. What size is the tubing coming off of that?
I feel the only downside to the awic is the weight. I have heard alot about them not being good for long durations of boost, but the 100,000 km record setting cars used the awic setup and they were on boost for 16 days. If the system is good I don't see a problem with them.

Tubing size is in metric, but the closest US size is 5/8" I believe.
The big thing with AWIC setups is, once you do heat soak the system, it becomes difficult to cool it back down. But otherwise they're great IMO.
I haven't had any way to monitor charge temps. But do know the system works well with cooler temps. In stop & go & city traffic temps are little warmer.
During the summer down here, the AWIC was hot....but don't recall it being engine temp hot.
Either way, it's always better to have more radiator capacity then intercooler capcity so if your temps do get a little high, you'll have a little extra cooling capacity to bring them back into check.

What is the metric size of the tubes? I've had a lot of sudden inspiration and this weird urge to want to do stuff to my car now that the front bumper is off and with all the bolt on bits of the RH front corner obliterated in a head on.Legacy777 wrote:Tubing size is in metric, but the closest US size is 5/8" I believe.

These common sizes interchange within the tolerance range of most tools.
5/16" = 8mm
7/16" = 11mm
1/2" = 13mm
9/16" = 14mm
5/8" = 16mm
11/16" = 17mm
3/4" = 19mm
5/16" = 8mm
7/16" = 11mm
1/2" = 13mm
9/16" = 14mm
5/8" = 16mm

Unless the fan is rated for outside use....it will probably fail prematurely.SubaruNation wrote:i'm going to install a computer fan (the big kind) in my engine bay to prevent the heat-soak, i think it might be a good idea for the AWIC also.
I had thought about putting a separate skinner pusher fan on.....depending on the room, I may....we'll see.

I find that it's easiest to use a radiator and fan from a motorcycle. Then, the unit can be mounted almost anywhere and the parts are designed for severe duty. They are usually very compact as well.
I'm going to relocate my battery to the rear of the car and use the space for my AWIC.

I mounted a motorcycle fan (thank you GSXR 1000!) pulling air on the underside of the TMIC on my OBS-T relayed to turn on with the radiator fans.
This caused the intake temp to increase about 3* so it came off.
Since I did not have the correct splitter for the TMIC the bike fan was pulling hot air from the rad/engine bay through the I/C & causing intake temps to increase.
I never tried powering the fan on whenever the car was on which may reduce charge temps, but I have alky injection on that car so the fan was really not needed.
+1 on the bike rads / fans working well for AWIC set-ups.

I bought a set of pwr exchangers.....and while their size is a little bigger then I wanted, I was hopefully to get them to fit. However when I got them, the exchangers are not square/plumb. The end tanks look bowed as well. For $210 a piece, I expect a lot better quality. I bet their welding jig is fubared. So back to the search.
