I got an idea for an intercooler that would be a keeper.

Buy this:

Use the OE TDI pipes or make something like this:

Place intercooler near battery. Mount fan. Done.

You mean use the old I/C as the water radiator for the air-to-water I/C?

I bought one on Ebay about the size of a TDI IC with a fan attached, $20.

Isaw a thread somewhere, I guy installed copper tubing(coil) in front of his IC with tiny holes in the tubing. Plumbed liquid CO2 thru a solenoid, then sprayed -109 CO2 acrossed the IC. This was for racing.

you can spray them with alcohol to.Just reroute the windshield sprayers

I can only imagine what the intake air temp. would be spraying -109F CO2 maybe 30-50. Great for a 100F July day. Do you guys remember the "cool cans"? Fuel (gas) ran into a can filled with either ice or dry ice before going to carb.

Yeah I remember them, my friend had one on his new 69 Z-28 he paid $4,200 for brand new, wish it were those days again.
Maby for a real red-neck intercooer we could just take a {big} Igloo ice cooler, cut a couple 2 in. holes in the sides and coil up about 3 or 4 feet of shop vac hose and set it on the other front seat and fill it full of ice and keep our beer cold at the same time. The ice and beer should run out about the same time and we could just start the process all over again if enough time and sobriety permits. Hell I gotta stop thinking about these little cars, I'm gonna hurt myself :lol:

But you have to watch how close you put the cooler to the heated tank of Veggie oil that also is in the front seat(caddy)

Well a shelf set-up would fix that too, just put the cooler in the closest place, if there stll isn't enough room there is still the whole bed to use in back. Small freezer and a portable generator :lol:

If you took that fogger nozzle and put it in you intake, your air temps will go done plus get more hp from the nitrous.

Clutch wont hold.. trust I would do it :lol:

unless you add more fuel you won't get more power from the nitrous, unless you were previously blowing out black clouds. :lol: it would really decrease the EGT's though.

Nitrous is too expensive just to blow it on the intercooler.

i totally agree. my biggest arguement against nos to my buddies is.. "well, what happens when you run out of nos? see, unlike you, im not just gonna run out of turbo. as long as theres air to breathe, im set!"

You know, i own an outdated turbocharger systems book from the 80's and it describes (not too specifically) and diagrams a system which is akin to the old oil-fired refrigerators. From what I remember, this setup makes use of a more volatile engine coolant which is allowed to boil while leaving the engine (hot). The hot coolant is forced through a venturi aspirator as it expands which draws a secondary circuit of refrigerant into low-pressure effectively pulling heat energy from it. The refrigerant is used to cool the charge air with an exchanger like a liquid IC or something and is returned to the aspirator to cool off again. The engine coolant, after have expanded from the aspirator nozzle is sent to a condenser (its radiator) and then enters then engine again through the coolant pump.

It's a neat practice in thermodynamics. Waste heat from the engine is used to actively remove heat from the charge air. In theory, it's pretty cool. Waste exhaust energy compresses the charge air via the turbo and then waste coolant energy cools the air via this refrigerant system. In practice it is likely not very efficient and probably has seriously limited lower bounds on how cool a temperature it can maintain the refrigerant to. I think I remember reading that this system is appropriate (if for anything) for very high temp charge air. It could drops temps from 400F down to 150F or something. You couldn't take 250F charge air and make it 50F.

Does anyone know more about that I am (trying) to describe? I have to dig that book out.
