Food for thought....
I built an Intercooler Chiller out of a plastic spider and distribution tubes for a swamp cooler (evaporative house cooler used in dry climates like mine), a hobbs pressure switch, an adjustible electric fan thermostat, and a shorty CO2 bottle that will be mounted valve down to get liquid.
I will also have a manual override so i can cool down the air conditioning condenser on hot days!
Haven't installed it yet, but I'll let you all know how well it works.
Thoughts?

 

I was recently thinking of a way to cool the air charge better. Let me know how it works.

 

Can't hurt. Let us know how it goes.

 

FOOD FOR THOUGHT....

Since we are on the topic of cooling the incoming air how about the
idea of using the A/C for cooler temps.

I have seen some small vans with dual A/C, all they do is split the low side
and the high side. The ones I have seen only use one expansion valve
to feed both evaporators at the same time.

Since it's summer time and the A/C is usually running anyway, why not.
It wouldn't take a lot to modify the air intake to run thru the A/C and cool
the air to ??? temp. My A/c blows cold air at 32* to 38* at the vents.





OK lets make it or brake it on this train of thought.

At full boost the air coming out of the compressor can be over 350 degrees. You'd need a much bigger A/C system to cool that down.

 

I was looking at cooling the air BEFORE the turbo.


Thinking again???

 

Anybody ever try misting the aftercooler. Bathing it in mist should give some cooling, especially in summer.

Maybe I'll put a swamp cooler to the front grill.

 

Doesn't make sense to try to cool the intercooler directly with the air conditioning because the condenser will put more heat back than you can take out. It does make sense to use a water/air charge cooler and cool the water all the time, so it's cold when you need it. 'Course that's a bit more complicated than just spraying the whole dang mess with liquid CO2 or H2O!

 

Or liquid nitrogen hehe

 

I think you would be more efficient if you used a small chilled water system, your AC could be used to chill the brine and then pump that to your exchanger. The small tank could be mounted in the bed of your truck. Chilled water systems are used in large cooling systems today, also aboard ships.
You could also use an ICE bath to chill the water but you will have to keep putting in ice cubes. Check this link.

I'm not sure you would gain anything by doing that. As wannadiesel stated above the temps coming out of the compressor will still be very high.

 

Just behind the turbo might be the sweet spot. I'm going to test and see. My guess is, like I said, the more time the water has to vaporize the more the pressure rises (water expands roughly 1,000% when it vaporizes).

 

The ricers do this by spraying N2O on the intercooler, it apparently works but what a waste of good "NOS" FWIW, when I was working for Mitsubishi, the Evo has a spray bar mounted at the top of the intercooler and under high loads it sprays right into the cooler core, has a separate tank,pump and all. I never had the chance to hook up the scan tool to see how much it dropped intake air temps but since i work for toyota now...it`s a moot point I guess

 

the srt-4s are also putting spray bars in front of their intercoolers and actually sprays from the winshield washer tank. again i dont know how much of a gain it is but it is part of mopar's stage 2 kit. it has a little toggle inside of the car and you just flip it and go. even if it is only 10 degrees it still helps for those that need every horsepower they can get, or for the rest of us that are greedy !!!!!

 

Old racing days. Would just make a quick cooling can with Dry Ice in there and having the gas line flow through it to cool that down (track days only, not full time). Would that work having the air some how go through dry ice in a can.

Granted, this would take a lot of dry ice for a daily thing but it might work just for race day at the tracks.
