The link above is a rendering of the intercooler chiller I am working on. I'm going to try water first, and then liquid CO2!!! I have it designed to fit in the narrow space between the condenser and the grill of a 1st gen truck.

Feedback?

Interested to see your results. Will complement you on the clean design.

Would think that a water/alcohol mix would work well, but CO2?????

I would guess you are using an "on demand" pump controlled by a solenoid? Wonder if you could tie that idea in with a pressure switch to kick on when you get xx boost?

I love creating (rubbing hands and in best Rube Goldberg voice)

Keep us posted.

I'm using a pressure switch and a manual override so i can cool down the condenser when I get into the truck on hot days.

I am nervous about spraying alcohol on hot engine parts, first because of fire, and second because alcohol tends to be caustic.

CO2 will cool it to -200f or something like that, but I don't know how long my shorty tank will last. Going to test all of that soon.

Thanks

 

I would be concerned about thermal shock with the CO2. Water will be no big deal, but CO2 will easily drop the temp to the point that the intercooler or condenser cracks from the localized cooling.



With CO2 you would be best served by turning the nozzles around so they spray out the front. This will cool the incoming air and prevent you from having any cracking problems.

 

I was thinking since it wouls be hitting the air conditioning condenser first the shock to the intercooler would be minimized.
That's a good idea though. Maybe if I turn the nozzles sideways?

 

I changed the design for better distribution of the CO2. I have sent my autocad file of the distribution block to the machinist.
Here are a couple of views.

Mark, are you planning to drill orifices along the tubes and then crimp the ends shut? It's hard to tell from the pic. This design looks like it will cover more area, and it also looks simpler to build. Maybe drill the orifices on the top and bottom of the tubes, I still think CO2 directly on the condenser is a bad idea.

 

I plan on drilling a "Splayed" arrangement for the sprayers, and the tubes will be braised closed on the ends. I'm adding a temperature sensor placed in the fins of the intercooler so that it does not activate the system when it does not need it, and am going to start out testing with a 10psi switch controlling the solenoid for the CO2.

 

Sounds good to me.

 

What pressure are you planning to inject the Co2 at? full tank pressure?
Also do you have any idea on how much horsepower you might loose due to the engine
injesting the Co2 vapor through your air cleaner?
Wouldn't this be like unloading a Co2 extinguisher into your engine air cleaner?
Couldn't you a cryo that would be benificial to both chill and combustion?
LOX would come to mind.

 

I'd be really reluctant to spray oxygen onto a hot greasy Cummins. Can you say car-b-cue?

At speed I don't think the air cleaner would see any CO2. If he built a ram air system like yours he'd have no problem at any speed.

 

I've seen them spray nitrous on intercoolers also. Might get a little pricy, but would work. It looks cool. Good luck

 

Like Wanna said, I am uncomfortable spraying oxygen on hot grease. I have seen grease spontaniously combust with the O2 from a torch. Don't want to Chernobyl my Dodge!
I am going to figure out a "fresh air" setup so there is no potential for dilution of the inlet charge.

Hey Dave, how did you get the picture to show up earlier in this thread?
