Has anybody heard of this? or thought of it?

I came up with a similar idea of running the ac through a water to air cooler instead of water but I have doubts on the effectiveness of such an idea.

Thoughts please!

 

I have seen one on a EVO before but not really sure how it worked I never was able to find the guy who owned the car. It does seem like a pretty good Idea Im just not sure I would want to chance it, to me it just seems like added something else that can fail on the car.

 

You press a button and it fires co2 through the cooler which is similar in principle to a water/air cooler (as opposed to a conventional air/air intercooler)
the expanding co2 takes the heat out of the cooler so much that it pretty much flash freezes it, and the air passing through the cooler is cooled.

It seems to have several problems though..
1: It will create a HUGE amount of condensation.
2: If it develops a hole your engine will seize.
3: Restriction.
4: Limited amount of co2

 

I feel like if you want to super freeze your intake temps, just do it the way people have been doing it for years and put nitrous on your car

 

Just use 100% methanol injection..

 

I'm thinking the same too.

But I was thinking surely theres a renewable way of keeping intake temps below ambient and not just squirting in whatever whenever.

Back in the 80's, a guy named Buddy Ingersoll showed to in his pro stock turbo Buick with a liquid nitrogen cooled intercooler...needless to say he was turned down from making a pass. Bit of interesting NHRA history.

 

The mustang guys use a system that taps into the refrigerant system. It works, but your A/C performance does take a hit and it's a bit bulky, however you're not always filling a water tank.

If you wanted cheap uber cold temps, just dump some dry ice into your 100% methanol. I don't recommend this as methanol is extremely volatile and it's flame is invisible should it catch fire, but solid CO2 (aka dry ice you can get at your local grocer) is about -78C well above the freezing temp of methanol or ethanol and it will bring the meth to that temp. I'd crush it a bit in a pillow case first before adding it. Remember -78C is outrageously cold, if anyone tries this don't hold me responsible if it damages your pump. Not to many things are made to work at that temperature. Additionally don't entertain the idea of sticking your hand in it. It WILL take your skin off.

 

some land speed guys experimented with co2 and nitrogen cooling coils in the intake years ago, guess what... Not a single one still uses it.

The air flows through so fast that it doesnt really cool the air as much as you'd think.

Be careful cooling fuel that much (in the case of cooling meth) when fuel is very cold it wont atomize. The hotter the fuel is the better it works.

Its really a simple issue. If you have too much heat the get a bigger intercooler or more importantly turn the boost down. If the turbo is running where its efficient then it wont heat the air that much anyway.
