Intercooler Coolant formulation?
Has anyone got any experience with running a dry ice / alcohol slurry instead of an aqueous coolant? If so, any success? If not, why?
To be clear, i want to separate the motor and intercooler fluids and replace the intercooler fluid with one that is COLD.

obviously (or maybe not) you can't run dry ice in a pressurized/sealed system. alcohol...never tried it, but i have run ice water and it's worth a tenth off my et and a mph at the end of the track. i don't know how much hp that equates to and i don't really care as i don't put any stock in dyno numbers. however, it takes a large reservoir and the tiny evo type isn't going to work. within a few seconds of circulating the ice water through the system, it's warm so it doesn't last long at all and imho not worth the trouble unless you're going for a record pass.
i have considered wrapping the reservoir in a dry ice blanket but the blankets i looked at were stupid expensive so i passed.

I been thinking why you cannot hook up the air conditioner somehow to super cool the intercooler. So you got the A/C draining power and the colder air making power - I guess in the end its zero sum game at best tho or?
Playing with the fluids insiode the cooler hmm... dunno might work - think of the I/C as the cold side of the fridge and another heat exchanger as the hot side... but this needs power to run but could be run off the battery for a short while I reckon.

it would be better run off of an electric pump so it's not parasitic to the motor.regardless, it's amazing we have to think of bs like this because tuners want to rape us for $15k on a $1000 intercooler.

Mine is 20F over outside temp all time in summer here in NM so I think im OK but my buddy told me to do water injection i dont know if any go bad for long run.

*** long as the system is sealed, I don't see what the issue would be? It would definitely be a pain in the butt and I would only do it for racing. But, you could bring a jug of the slurry (alcohol + dry ice) to the track in a cooler. Drain the current fluid (whatever the normal solution is as long as it is missible with the slurry) and dump in the cold fluid. The dry ice would keep the fluid cold enough for at least 1 run and likely more. The Alcohol would help dissipate faster and is less dense so less heat soak when it does get warm. Just a thought to keep the weight down. Putting a larger reservoir in the trunk is an option, but I was hoping to drop weight and add cooling.
Obviously, the intent is to run a separate system for the IC cooler.

Okay what about this though.
What if you just connected the coolant lines up to the intercooler water lines. So ice cold coolant would be flowing through the intercooler. System already has an evaporator on it etc, you would just be extending the lines out a bit and running them through the intercooler
.
I know I know, impossible.
Is it just too much pressure for the intercooler fins ya think.
What would happen if you just went nuts and tried it for an experiement??
Guess I just don't know my HVAC stuff so maybe it wouldn't do anything at all. Just keep thinking about those ice cold lines even in a piping hot engine compartment.

I guess another route is a jacketted vessel. How about that, then? I'm just thinking out loud. I'm not standing over my car with a wrench.

You seem to have all the answers, so try it out and let us know how it works.....

I appreciate you trying to think outside the box, but others have come before you with experience in this specific mod. Those people are trying to tell you it wont work. If you think it does relative to you own experience, then knock yourself out, you wont see me stopping you. Sore, not in the slightest, that would mean your word means something to me, you have proven its worth zero, along with your extremely naive and limited knowledge. (said in a deep voice as I stare down at you from the mountain top) Not trying to start another argument, just stating facts
Ok, I guess you da man. Its a good thing all of this has been figured out.

I would say getting water injection would be the best result, and far easier to implement. Many fully auto systems around that piggy back off injector flow...
Won't really give you much max performance gain I dont think, but will allow you to run the car flat out with much reduced IAT's - which is what the goal ultimately is...
Think I am going to have another look at this.

My friend has tried using the air-con to chill his intercooler fluid and it does help bring down temperatures fast after a run and lowers the cruising/idling temperature, but it didn't reduce peak IATs much. This was on his CLS55 using a custom intercooler

I think I am going to try this HFS-5 Aquamist unit ... seems reasonably simple install and if the guys give me decent backup in getting it setup right.
App 50degC drop in IAT's...
