Thread: Deuce Battery Placement

Here's a shot of my home-made trans cooler.
2" thin wall tubing, plugged at both ends, a couple of 1/4-NPT threaded weld bungs welded in.

1/4-NPT to #4 AN stainless braided line.

Used in conjunction with a Derale trans cooling pan - the model with cooling tubes running through the 1" deeper pan.

It works very well in cooling the T-400 behind the 462" Buick in my 32 roadster.

The only time the trans ever got warm was running the switchbacks gong up to Sequoia National Park on a hot summer day.
That due to the 2400 rpm stall converter not locking up all the way.

A 20 minute stop at the view site and things cooled down enough to make it the rest of the way.

I run this setup here in the Arizona desert in weather up to 103 and have run it on Nevada's highways in 107 degree heat.
As long as the converter is locked up it does very well and I have yet to get the trans over 190 running the desert highways.

My 31 on 32 rails project roadster has the same cooling setup although 1 3/4" thinwall tubing is used on it.
(You don't want to go too thin, maybe 16 gage at the very most and 18 gage works just fine.)

As a fwiw - I believe the stock spreader tubing is 1 1/2" OD tubing and it would probably work ok.

Thing is, with the 2" tubing there is over 120 square inches of radiation area.
Black powder is used on the 32" cooler and black is known to radiate heat better than any other color.
You probably wouldn't lose too much by using a different color.

A tubing trans cooler such as this is known in the aircraft industry as a "Skin Effect Radiator."
