So... Im thinking about a portable way to make an A/C system for my v8...

But. here are the limitations.

I will not rob any hp by putting on a compressor. (more belts to possibly fail)

The unit has to be completely removable

The unit cant cost more than 150 in parts or 200 premade.


Here are a couple of options that im thinking. along with pro's/cons

ICE BOX
Build a box that holds ice packs and ice, throw some fans, some switches, ect, and get some ice cold air coming at me.

Pro's. Cheap, 20 bucks in airplane fans, metal/wood is cheep, Plastic sealing, Mesh for the ice to sit on, switches, and an lighter plug..

Cons. Sealing it will be a problem, Drain off might cause some issues, Ice will only last an hour max, ice packs will be maybe 2 hours cold.


PREMADE

Couple of company's are out there making beverage coolers and warmers..

Even

Pro's.. No fab...

Cons.. Not for cooling the car, but food


Thermoelectric...

Now it gets interesting... I read some stuff, and noticed most of the coolers are using this thermo electric thing... Now how can I make this into something useful?

If I understand it right, one polarity heats up one plate, and one polarity freezes another plate.

So..

If I used them instead of ice... I might get some pretty darn good cooling output?!?
But what about power usage?

Those little things I just dont understand... Anyone want to help me and tell me if im dreaming?

Thanks

Andrew

Demick, I was running a 914 heater fan. Dual outlet type (the one in the engine bay) I can not FIND a fan that will work... I need it small enough as to not be able to take a passanger... Also, Its possible to slow those RC fans with resistors right? Send me a link to a fan you think might work.. I have looked everywhere.

Anthony, A/C compressors take percentages. like 5-10 percent. On a 350hp engine.. 15-35hp? My race engine will be 500hp. I dont want the extra belt on the engine, then the lines to run the a/c, the condenser, evaporator, bla bla bla bla.. Your talking another 100lbs of weight added to the car.
NO. I will not run a standard a/c system. This system will be designed to be completely removable.

have you thought about using a blower fan from the engine compartment? If you don't have your's anymore I'm sure someone in this club has an extra. I mean if it can blow hot air through the HE's then it should be able to do what you want... just a thought

The fan that sits next to the gas tank will blow plenty of air. The big squirrel cage ones push a lot of air/pressure when unencumbered by all the rest of the pluming. The intake/exhaust would fit right on top of the cooler. I assume you have a way to get the air to re-enter the cooler? If you had a compact inner-cooler It might work better??? My old Mazda RX7 had a small compact IC which would work well if frozen in a block of Ice, and wouldn't restrict flow at all.
Keep up the R&D (IMG:style_emoticons/default/clap56.gif)
