Made by C&R/Visteon

Its flipping huge, it should work just fine =)

This isnt the actual item btw, just a random pic of another one that I found so that I could post a pic =P

[TWOptSL0W]

damn is that monster gonna fit?

[I Love Brownies]

thats not big enough.












lol jk

[06Speed6]

Yeah I will make it fit, it is absolutely huge lol.

I picked it up for $100 on ebay, it was an old nascar oil cooler. I am going to cut the tanks off of it and run engine degreaser through it to get all of the oil out, then I am going to take it go a welder and have him weld up some new tanks for it that have 3/4" NPT fittings. Then I am going to take the front bumper off and take the car to the welder and have them weld up a bracket so that it bolts in.

I have two 14" spal fans on the way as well as a fan controller. So it should cool just fine in stop and go traffic here in Texas.

[TWOptSL0W]

will you have to remove your crashbar then?

[laxplayermjd]

are you using this for a radiator?

[superskaterxes]

when u gona put this F1 car together lol

[MATT DAMOND]

Awesome Marcus, cannot wait to see this come together.

What are you using for the core?

[cletusb]

For an A/W (Air/Water) inter-cooler?

[06Speed6]

Yes that radiator is what I am using for my A/W intercooler heat exchanger. There are a few twin turbo type drag cars that also use it as a precooler before the ice tank.

Its going to be really neat.

I have no plans to cut the crash bar out, there is no reason that I shouldnt be able to get it in there considering that it is less than 2" thick.

[Enki]

Isn't it a bit overkill? I mean I can see using it as BOTH a storage container for extra thermal mass (coolant) AND exchanger but even then...That's huge.

[06Speed6]

I live in Texas, I need an absolutely enormous heat enchanger because of the ambient temps we have here. This thing should be completely 06Speed6 style overkill, which is exactly how I like it.

I already have a welder in San Antonio lined up... I swear if I wasnt so picky about shit I would have gotten a welder here, but no I had to have the best. I already have a phone number for a local welder that can weld circles around most welders...

Maybe I should just use the local one.

/sigh

[06Speed6]

It arrived today and it is flipping badass. Ill post some pics tomorrow.

[cletusb]

Awesome please do. Where are you putting the rest of the system?

I was thinking about adding a A/W to the TMIC.. prob silly but want something up the front without cutting ANYthing

Part of the problem with the stock TMIC is the terrible pressure drop due to the thin core. Not that you wouldn't see an improvement, but you'd be giving up some HP by not going to a better flowing core.

Oh I have the Corksport TMIC
Adding the system after that is the current plan. Figured it was the best way to get to FMIC-like temps minus the cutting etc

[06Speed6]

A A/W intercooler has nothing to do with a FMIC or TMIC. It is a completely different animal.

With a air to water system you are cooling water that is cooling the air, with both the TMIC and FMIC you are directing cooling the air.

The advantage to the air to water system is that water can absorb alot more heat than air, so it is able to cool the air much better with a smaller intercooler. The benefits of that are two fold, first the air has a easier time getting through the smaller intercooler, so less energy is wasted, second the intake temps can be alot lower than a compairably sized air to air intercooler.

A ninja third trick is that you can pump the water through an ice box, this will allow the water to cool the air ALOT more which will give the air to water system an even bigger advantage.

[LuczOr]

I want lta! Was thinking of fabricating my own, but I'm not sure where to put the air cooler. Was thinking of relocating battery.

[Enki]

I've got an idea that would keep it sleeper, but I don't want to say anything just yet as it might not be feasible. Suffice it to say, I've got mock up materials and will be stripping my engine bay to test fit.

[06Speed6]

I mocked up the heat exchanger and it fits lol. The crash bar doesnt have to be removed or modded either. I have some brackets drawn up and I am going to take them and the tcase bearing caps to a machinist/welder here locally.

I am going to cut the AN-12 fitting off and have them weld on some NPT fittings.

I need to find a spot to relocate the air bag sensor, thats gonna be a pain, and I had to remove the bracket that goes from the crash bar to the hood latch, it was perfectly in my way =P

[Rich-PMS]

Where's the pictures?


Idk where exactly in TX you are, but hit up Jtran Studios and tell them I sent you. See of they can help you. Their custom fabrication is amazing

With any luck, this is what I'm hoping to be able to avoid. If it works, I'll be able to yank 90% of the parts within an hour.

I'll make a new thread when the time comes.

[06Speed6]

Yeah I really wanted to avoid moving that sensor but there is no way around it.

[06Speed6]

This was alot harder than I thought it was going to be, I have spent two days fabbing and tweaking stuff to get it to fit, and I finally did it. I have enough room behind it for at least a 14" puller fan, and maybe even a 16". Ill have to get the exact thickness of the fans and measure it out to be sure which one I can fit.

I swear, if this thing was 1" larger in any direction, it would not have fit.

I have some 2" angle aluminum that I am going to use on the skirt thing to hold it in place, it should work perfectly.

[06Speed6]

I got everything finished tonight, I had to remake the bracket that holds the air bag sensor. I mounted it to the top left bolt on the A/C condensor. I also installed a Bosch 3 bar map and its working fantastic.

I need to order some parts before I can bolt the intercooler on, but its lookin damn good so far.

[I Love Brownies]

looks good man i wanna see the results with this beast

[topher3134]

MY question would be how will this change the temp of the air hitting the radiator? I have always wondered if the car will run hotter cause of the air hitting the radiator being that much hotter?

[Enki]

Temps will increase marginally, especially with a stock turbo. Not so much with a big turbo running inside efficiency band.

[06Speed6]

The temp increase should be on par with a fmic. Once I add a fan it will probably be lower than with a fmic.

[06Speed6]

So I installed the rest of the a/w intercooler yesterday and man does it look nice. Then on the first run I blew a boost tube off, fml...

Did I say that a a/w intercooler looks seriously baller? Ok

[crazyp]

one of these days we need to meet up
Where the hell are the pics?

[superskaterxes]

yea wtf!!!!! picts!!!

[06Speed6]

Later tonight man :-)

[dot584]

This looks badass! Pics and log temps would be awesome.

[06Speed6]

Well, I am still working to get all of the air out of the system, but I can say that it doesnt really heat soak at all at a stop and it drops back down close to ambient temps at around 1 degree every couple seconds. Also after a high boost run I found that both the heat exchanger and the a/w intercooler work to cool the water so it goes back close to ambient temps within seconds.

Once I fully bleed the system of air, I will need to retune it because I am hitting all of my load targets alot earlier. This thing is waaayy better than the ets tmic that I was running.

[CVPhere]

Heat exchanger looks nice but i wanna see engine bay pics

[chuckms6]

WOT logs? I just wanna compare bats against another setup so I can try to improve mine.

tapatalkin to you

[06Speed6]

Yeah ill post some logs when I get everything sorted.

Ill post pics of the engine bay in a couple days, its kinda torn up right now.

[06Speed6]

Alright i finally figured out how to get the air out of the system, you take a small plastic funnel and jam it into the ic and fill it with water, turn the pump on and keep adding water until the bubbles stop.

I did a couple runs last night, 70* amb temp, 90-130* iat, 115-120* bat while driving around town, it holds a very narrow range which is very nice, i just wish that range was lower. At a stop my bat is lower than my iat which is weird to see.

I did a couple wot 6th gear runs and by the time i could brake back down and start the run over it had already cooled back down. I am running ~20psi and 2.2ish load, stock turbo. It reached a max of 155* bat at the end of a 0-150mph run where I was shifting in the 4k range to make the run last as long as possible, by time time I could slow down to 70mph it was back in the low 120* range.

I think if I added a fan it would lower the temps some more. I also noticed that in low load and low rpm conditions the bat doesnt seem accurate for air temps, it seems to more closely follow manifold temps.

[chuckms6]

sounds pretty close to what mine was a while ago. right now in 80 deg. weather on the 1/4 mile spiking 20-21 psi id trap at a touch under 180 deg.
idk much about your setup, but a couple things that helped my temps were water wetter, a thermal intake gasket, and having the shortest and straightest lines possible. i had to tweak mine for the longest to get it where its at now, but its worth it. the thermal intake gasket is what i feel helped the most, but i think the intake is still a terribly efficient heatsink and its hurting bats.
also idk how often you go to the track but i made a pit switch that turns the pump and fan on while the car is off in the pit lanes. that way im shedding as much heat as possible before the next run. people are most impressed when i pop the hood and they feel an ice cold intercooler
