Just remember, Guys and Gals, these trannys require a certain amount of coefficient of friction for the synchros to work properly. Too slick of fluid and the car won't shift right. The slicker the fluid, the slower the breaking action of the blocking rings and synchros.
Hey Gary, long time no chat.
I worked on a race car a little while ago and installed an engine cooler and a transmission cooler. I used the Tilton pumps and put the coolers in the back. I used a -10 hose to pull oil right from the back of the pan, then -8 everywhere else. The coolers were mounted on a framework where the spare tire well used to be. Then the trunk area was enclosed and vented thru the deck lid under the spoiler. This provides positive air flow across the coolers. I installed spin-on filters for both the oil and tranny just to keep things as clean as possible. This also doesn't effect the engine's own oil pump in any way. I'm pulling oil out from the back of the pan, then putting it right back into the pan, direclty in front of the pickup. This way the pump is drawing in the cooled oil.
The tranny cooler is the same way. It pulls oil from the bottom of the case, then puts it back in the fill plug. Intrerestingly enough, it now holds 5qts of tranmission fluid and 9qts of engine oil.
We also installed the battery down low in the right rear corner.
The point is durability for an endurance race. The weight distrobution is better and it should handle better. It's amazing how much heat is put off by these coolers.

Now thats the ticket!! Alot of good info here :thankyou:
But Since I'm such a nice guy.... I half took my bumper off to get some pics, It was easier then crawling under the car.
Here's the Line to the Cooler:
Going in to the Cooler:
And out to the Pump:
I don't exactly remember where exactly the Return line from the pump, to the trans goes to. It's cold and wet outside so I don't want to go under the car to get pics, Maybe Bob can Chime in on that.
It's activated by the fog-lamp switch.

Many years ago, as I was in on the first SHOShop Quaife group buy, my first road course outing with the Quaife was the now defunct 4.5 mile long course at Denver's Ex-Stapleton Airport - big high-speed course, lots of fast sweepers, several 2nd gear turns, this course got lots of Quaife action.
Trans got to over 265F (sensor in the fluid, front wall of the trans case), the synchros got mighty unhappy.
Put in a Tilton pump and cooler, it stays below 220F on road courses now.
Here's the trans scavenge line with an in-line trash filter to the pump inlet.
Here's the pump on the subframe.
I have a pic of the coolers around here somewhere, here it is. PS on the left, oil in the middle, trans on the right.

What is the part number for the tilton pumps that you guy's are running?

Just got an update from the guy with the enduro car with all the coolers. He's thrilled.
He said that what kept him from being a contender was a bad wheel bearing. On Sat, they set the fastest lap and on Sun, they had the 3rd fastest lap. They ended up finishing 59th, after being out of the race for 73 laps. On one of the driver's stints, he made up 23 positions one lap.
The cooling system is the Bomb! He said that he thought the temp gauge was broken. During the race, it wouldn't get over 184 degrees, even without the electric cooling fans. He switched off the pumps and within 2 laps the temps climbed to 200 degrees. Then after switching the pumps back on, the temps fell back to 184 and wouldn't budge.
So....removing the heat from the oil has a huge impact on the cooling system.
