Thinking of replacing my heat exchanger with an interchiller that runs off Ac. They claim 40-60* drop in temps. Anybody have any experience?

 

Their must be some decent pickup from it if Dodge engineers Incorporated an a/c cooled intercooler in the demon.

 

there are a few aftermarket kits out there and just as many bad attempts marketed. Those offering these solutions don't have the equivalent R&D funds as an automaker so do not think they are similar in form or function. Just do plenty of research on your part and understand how the AC system as a whole works and what it demands from accessories i.e. compressor, radiator, cooling capacity and efficiency etc.

 

I had a "Kincaid" kit on my Ford lightning. It was great, worth every penny. Cruisn around with ac on in the hot summer n keepn iat s in check! I dont remember the exact data, jus that the ac still worked fine with it n there was a noticeable difference in power. Those trucks were prone to heatsoak with the big ole heat pumps on top of em

 

Well ,I drive with the Ac on constantly any way. I use a sanden compresser that doesn't put too much of a drain on things. I think it would be better overall since I can get rid of the 2 fans on the heat exchanger. I'm tempted to try it as all the data I've seen looks impressive

 

If it's a track car, the tech guys will "love it", when the condensate drips on the track..........

 

^^^^^Can have a catch can.

 

I think they addressed the water dripping issue. The track kits bypass the cabin Ac for this reason, (when at the track) and the unit is all enclosed and insulated.

 

SS Sedan owners look at http://fiinterchillers.com/ these guys have a good standing reputation as compared to others. it is an interesting concept.

 

So far , I've looked at F I interchillers $1700
Active interchiller $1200 , killer chiller $750
F.I. and actives product look very similar, killer is a little different .

 

As someone from local this product sounds amazing, however it looks like it would be a pain to get in a 4th gen. I like the idea

 

Didnt even know they were sold and had no idea that it was implemented on the demon. I did think about this idea a few years back, didnt run the numbers, but initially my thoughts were:

1. A larger heat capacity would be required from the AC system

2. To accomplish this, component size needs to be increased - larger compressor, condenser and tubing diameters would be needed in order to accomplish this most likely, but I would need to run the numbers.

3. More heat rejection from the condenser up front which downstream is the radiator and engine

4. Spinning an AC Compressor at high speeds for extended periods of time can be concerning from a durability standpoint

5. Increasing component size adds weight, system complexity, more components in the engine bay, and more potential leak paths and failure points.

 

Plenty of you tube videos. Just look up interchiller.

 

Don't go Killer Chiller. There's a reason he's banned on CTSVOwners. Active Interchillers isn't a bad company and i've seen his products work in the half mile and quarter, but it all comes down to word of mouth. FI Interchillers is based out of Australia I believe and can be a bit of a wait when it comes to needing replacement parts and stuff, but their customer service appears to be top notch. It really depends on what you're using the car for. Road Racing then no because the AC is going to kick itself off under heavy throttle and you'll eventually just lose all cooling. Its really only good for highway pulls up to maybe a mile. It essentially super cools the coolant in the system with the AC while you're at idle or low throttle and under wide open throttle it's cool enough to do a burst up to about a mile from my experience. I looked into it on my 09 CTS-V that makes 820 on E. I currently run a Vadder Destroyer heat exchanger that has been pretty good to me, but I live in Orlando where it's always hotter than Satan's *****.

 

Well I have an afco heat x with fans now. AITs are 25-30 over ambient. Hottest I've seen them is 120 . But who wouldn't love 40* AITs ? Plus I'm sure 4 fans running all the time is taking its toll on my alt. The sanden sd7 I'm running is good for 7000 rpm. It sees 6500-6800 all the time( it's not ecm controlled yet, but it's on my list)

 

It's been proven that a stock system has the capacity to supply both.
The AC compressor won't turn any faster than stock, The ecu will stop it before it reaches that point. The system is based on the concept that the vehicle will only see high rpms in shorter bursts and with everything insulated it will have enough reserve capacity stored to keep IATs cool during that period. You can also go with a larger reservoir to increase capacity if needed.

 

Couple of my friends here in Australia are running the FI Interchiller, one has problems, one doesn't - same car, same installer and tuner. Delivery is slooooow on replacement parts.

 

Well put. I think it will do well on my car as whipple has a huge intercooler.

 

Have one on a TT 427 Gen 2 V. I am still trying to get water/coolant down to advertised levels. I am bout 40 degrees over where they should be.

 

My IAT2 is typically only 8-13 over ambient, but thats not really helpful when ambient is 100+ lol

That seems to be the common issue. Of course you see the FI Interchiller's successes posted all over FB, but you don't see all the behind the scenes drama and issues that come with it.
