13B-RE 1/2 Bridge with all the goodies. BB T04R, Precision Turbo water/air I/C with custom mounting brackets. Let me know what you guys think.

 

One more for now...

 

ok
so um, your using an e-fan i take it?
how are you going to duct it?

 

yes, it will obviously need an e-fan. The radiator is a custom built unit and actually now will sit vertical instead of at a slant. The fan is a 3500cfm permacool unit with a custom aluminum shround

 

how much did the water to air IC set you back?

give us some feedback on the intake temps once you get it set up and what you used to cool it.

the water to air units always kind of perplexed me, i suppose it is only meant to use a dedicated cooled water source like chilled water that is only good for a single pass? i have never seen them setup on track cars because of this fact.

 

The I/C itself was $700, and then all of the supporting stuff including fab stuff was maybe another $600. The setup has a fuel cell for water and ice, a Bosch pump, and a radiator from a 4 wheeler for cooling. The only thing I haven't quite figured out is what to use for an antifreeze/corrosion inhibitor that is safe, since the sytem will have to be drained after ice melts at the track.

 

wouldn't that intercooler heat soak like a bitch with the hot air from the radiator blowing right at it.. i know that the flow is really good on the air to water.. but i dont know about cooling. i would imagine that the alum would suck up all the heat from the electric fan.

 

That was something I thought about and I have a giant roll of heat tape I'm going to wrap it with. I don't think it will be an issue but I will keep an eye on it.

 

yea that 180*-200* heat blowing on it may warm that up... too bad you couldnt put ir somewhere to the side

 

I wouldnt' worry to much about it, I assume this setup is for drag racing, so I dout your IC would have time to heat soak.. even at idle.. with the ice water running threw it it shouldn't be any kind of a problem... well atleast till the ice melts.

Looks like you will be having alot of fun on this setup soon. Good luck.

 

It will be street driven some but its by no means a DD. The heat exchanger on the front is pretty big and very efficient so I'm not worried about the heat in the I/C. The big reservior (fuel cell) should act as a heat exchanger of sorts as well. I think it should be way more efficient than an air/air cooler, even where it sits.

 

have you thought about moving the intercooler to somewhere out of the engine bay, like in the cabin with you? somewhere i have some pics of a 8 second mustang that has the IC in the passenger seat. I'll try to find them.

 

I though about it, but I am going for a stock, sleeper look and will have a full interior. I have a couple of buddies with sub-8 second mustangs that have their intercoolers in the trunks, but they have this huge amount of i/c piping running through the middle of the car. With water constantly being pumped through everything, I doubt it will have much time to take on any extra heat.

 

very interesting setup. will you be running a seperate dicated radiator for the air-water IC or just feed from the main radiator? Do you have any pics of your custom radiator?

 

I'm almost 99.9% sure that he has a heat exchanger (radiator) for the air to water IC..

It would be a pretty silly idea to use radiator water as that water will be 180-200+.. and you would want to keep the air tempture below 120*F...

 

Yah, well I'm just making sure...

 

Yeah, I do have a dedicated radiator just for the intercooler. It runs in series with everything. The water will be pumped out of the reservior, up through the bottom of the I/C, through the heat exchanger, and then back into the reservior. It was recomended to me to use an automatic tranny cooler, but I know fluid dynamics are wierd and a cooler made for hydraulic fluid is different for one for water. I ended up getting a really nice aluminum radiator from a utility ATV thats a nice size that fits good on the front end. I think it will work good.

 

These types of setups are starting to get more attention here is Aus. Most car's i've read about that are using one are still in the build, but it's certainly not just for drag cars. Everything from drag to street to track will use it well I reckon.

It's not for everyone though, as the cost will be higher and it's more complex. Plus a good air to air is proven.

 

I too am developing a similar system. See my old post. I plan on using a barrel IC per my diagram in the link.

I have the heat exchanger mounted per the attached pics. I'm not too worried about heat soak as long as the HX can handle the job.

The air/water IC is phase II to my FC but I do have the dual pass HX hooked up to my power steering fluid.

I'll be watching for your progress. Let us know how it works.

 

i like your setup too ynkeetratr. A friend of mine here is using one of the PWR barrel coolers. We are tuning the car right now but it seems to work real well even street driving. I'll put some more pics up after the weekend.
