atr aux ic
- Thread starter bloque
- Start date
The aux IC is intended to lower your charge air temp. the cooler the charge the more boost your engine can tolerate before knock starts to occur.
You can put together a similar setup for cheaper, by searching out a similar heat exchanger made by Hayden. You can choose a tranny cooler or heater core to use, just need to measure the area behind the grill and find a match.

Serious about performance
Mark's suggestions are very interesting. I've gone 12.5 on my stock truck so far with the stock IC Pump hotwired and just rubber heater hoses as the only IC mods. I was thinking of putting the Aux IC CCHE and Jabsco on there but we're talking about $200 to drop there and now I'm not so sure I want to do it anymore.
Does anyone have any hard evidence to suggest the Aux IC CCHE + higher volume IC Pump really gives any significant performance effect?
FWIW I just installed the SMC Alky (Single M10 nozzle) and I'm hoping that helps to lower my charge temps (or combustion chamber temps perhaps would be a better term?). Although I am sure I will never get as good a results as Mark got with his kit (25 PSI on 92 with no knock!!)

I noticed considerable change when I went with an aux cooler. Anything you do that lowers your MAT's is progress in a positive direction.
Your truck feels much stronger as the MAT's lower.
I think the atr kit is overpriced, I got my cooler for free, so I didn't hesistate to do the mod.
This is a typical debate that has come up lots of times, and theres so many different views that everyone is gonna argue. Some will say the bigger the pump and faster the circulation the better, and others will say the longer the water flows through the coolers the better heat transfer.
I would like to grab a big ol pump from a marine shop that flows some riduculous amount of gals/min and try it out, but I don't really care to spend the cash just for grins.
For a stock like setup truck, an aux cooler of some sort will lower MAT's.

I am surprised your stock pump still works (I wouyld guess someone has replaced it already). It seems like every truck that I looked at and most owner I talk to have had to replace the stock pump by now. So I guess I look at the higher volume pump as a replacement part. I look at an aux IC as a 100 mod. I have no real world experience with one yet.

bloque I would say if you have a good running ty that does not need anything else first then I would try the hayden aux ic, but I thik the money could be spent better on other things first, or air to air 8)
Hey Tooky if you want you can have my shur flo and aux ic and what ever hose I still have as I don't need it anymore.

You can buld one cheaper if you want to, Shur flo from campers choice for like 56.00 with shipping, the cooler you can get from summit, premacool just started making 4-6 row headered coolers, but I just put a shurflo and a fan on the cche. I can drive to work,35 miles one way and when I get there you can put your hand on the intercooler and it feels cool to the touch, and that's in the summer, and you can't even think of touching the intake.

I have the "true" ATR aux IC on both of my trucks. The Syclone came with it - Jim Newton installed it years ago. PEP installed the one on the Ty about 1 1/2 years ago. In the process of redoing *everything* on the Syclone Dennis is rerouting and rehosing the entire IC plumbing circiuit. He found that on the Syclone the aux cooler fittings were the very restrictive type sometimes used on heater core lines (to decrease the radiator bypass and increase cooling efficiency). On the Typhoon the fittings are non-restrictive. Well, the Typhoon IC setup did seem to work better than the Syclone - now we know why. Check those fittings! Needless to say Dennis opend those puppies *up*.
On the Typhoon, with the ATR aux IC with nonrestrictive fittings, and with the Griffin lower CCHE I saw a major improvement in MAT's. Before the upgrades, the MAT's would run 30 - 50 degrees over ambient while cruising but drop during a high speed run, in the short term anyway. During a pull the MAT's would rise. After the upgrade, the MAT's were within 5 - 10 of ambient and increased during a pull to 20 - 30 degrees above ambient, then drop back down immediately when going off boost. This is more in line with what you'd expect from an efficient IC. I'm speculating that the drop in MAT during high speed cruising meant that the stock CCHE was inadequate and that it took very high airflow through it to achieve effective cooling - but only when not in boost. Under boost it was completely inadequate, due to both inadequate capacity and inadequate flow.
As far as the pump capacity goes, we're going higher - to the Meziere 20 gpm electric remote mount inline IC pump. Its designed for continuous duty with hot water.

They were talking about engine cooling but why shouldn't it apply to the IC as well.Stewart Components said:

Oh yeah, another thing - if you've done the replacement and rerouting of the stock metal IC lines than watch for bends in the hoses coming out the back of the IC restricting flow. And of course there's been the reports of bends causing restriction going in and out of the stock lower CCHE.
Any restriction wil screw the pooch.

The ATR aux CCHE ( heat exchanger, not IC) is an interesting peice. It is engineered by Hayden(?) to cool oil, not water. I dont like them, and would run a cche engineered to cool water, not oil. I used to run a rather large heater core up front and found it to work well. It has been removed for a few years now in favor of simplicity. At the track mat temps didnt change before and after Aux IC removal, but the difference on the street was tangible. Anyway, using a tranny cooler to cool water is a waste of time. I always wanted to get a motorcycle radiator with a built in fan and give that a shot, but went to alky before that was executed.
Spending the cash on Alky is by far, the way to go IMHO..

Which CCHE?
Which CCHE?
I'm looking for a stock replacement of the original CCHE. I am interested in the product by Atomic Rooster Motor Autosports but recently joined with Race Proven Motorsports and from what I was told was going to be a discontinued/no longer carried product. It's unfortunate because it was a direct replacement that flowed better than stock. Anyone else know of a direct replacement similar to this one?

I now agree with the atr core being an incorrect piece. I have had a hayden unit on the truck for a while, its a bit smaller from end to end, but not much.
Anyway, 1 big thing is its hard to get air out of the system.
The cooler uses tube/fin design unlike ALL OTHER WATER RATIATORS on the market for anything. Not to mention it is not a multi pass design, but rather a high flow design that only passes the fluid through it once.
the hayden/atr unit is an oil type cooler, and I will be looking for a motorcycle radiator to replace my hayden.
As for some vauge facts: I have a jabsco, stock lower, and hayden.
Compared to another stock truck(temp gauges on both), my temps are always lower then just the stock cche.
Now.. I busted my stock lower cche, and had to patch it up to run with just the hayden. It is now obviously hotter then the stock cche truck (and this is with the cooler getting as DIRECT of a flow as possible...not to mention a fan pulling air through it).
