In my opinion the Killer Chiller is worthy of what there asking for it, I wouldn't think a home made kit would be anymore efficient either.

 

Put your core low in the tank, but the water outlet below it. Make your water return above it. Forcing water to go through the new AC core as much as possible. Also if you want to add ICE to it at the track for even more cooling the core acts like a screen.
Having the core LOW in the tank it will help chill all the water even if your water pump is not running. (I highly recommend running that pump all the time. )
Are gonna do just the low side or are you installing an expansion valve also.?
Wrap your tank with AC dust foam, if laid out correctly you will only have 2 seams to seal with tape. I would set up a small vacuum line running to a catch can from a low side point so any condensation between tank and foam has somewhere to go. The stuff they use for duct work in house etc. Roughly 1/2 or 3/4 thick. And has great insulation properties. And it does not look bad either
You can also DOUBLE wall your IC piping so cold water is circulation around those pipes. And then wrap them with header wrap or shiny thermal sleeve. OR both
As far as at the track its doable. Take you drain and route to a catch can under the truck. Just remember to empty all the water before each run.

 

You'd be surprised.

 

Why would you need to install an expansion valve? Could you not just run the liquid refrigerant straight through?

 

IM gonna give it a try..

i like your ideas Rick. Ill see what i can do.

What about a "auger screw" style setup so the water has to make circles around the inside of the intake tube/pipe?

Prolly just the low side.

I have no idea about AC stuff so i guess im fixin to learn.

 

Low side only is the easiest. Just go from silver tank on fire wall to new tank. To ac compressor. Basically just making the low side line longer.
I think gets plenty cold.

The reason to go ac hi side/expansion valve. Colder drop. Freon would be expanding I. The core. Problem is it complicates the build. Uses Y's on hi side and low side.
I don't like this way because of the complexity. Problematic with leaks etc etc.

 

Looking forward to your results.

 

In for results...keep us posted

 

Ill sure be posting them up.

Just got a call from a neighbor down the road. He does vintage air in old cars and builds some awesome stuff from the ground up. He wants me to come on part time to do wiring and help trouble shoot some AC systems. He has all the tools/gauges/machines for AC so its gonna work out perfect ha.

Now suggestions on how to run lines out of tank?
Just run stainless tubing in and weld it for a bulkhead?
What fittings I need for the factory hose?
Go to junkyard and cut some oem parts off?

 

We just cut up stock stuff welded it up. So the factory oring connections were reused.
But might check ac shop and see what they recommend.
