Differential Cooler and Breather

Just finished install of Diff Breather and cooler:

Remove Diff cover and Drill/Re Tap for Temp sensor:

Mount Pump in Spare wheel well:

Hoses:
Lower fitting goes to cooler, upper fitting to pump outlet, to keep pump fluid temps cooler.

Wiring:
I'm using an Aerometer gauge to trigger pump and cooler fan at 230 F.

Mounted relay and manual toggle switch (to prime/drain diff fluid when I change fluid) in rear wheel well (attached to rear mounted battery box).

Ran 2 wires to Smart junction box for relay trigger (3 amp add a fuse) and power (15 amp add a fuse).

How about a two bung canister and use the second to vent under the car. I could cap the the vent. That would make this a very long vent tube with a can to catch any oil that travels that far. :)

The friction modifier in not needed with the Torsen diff and I don't use it.
 
Great, now I got another fluid to worry about while tracking...
So how much does one of these diff cooling systems cost anyways? Two arms and a leg? Because I'm running out of limbs :p

I don't use friction modifier (as you say, not required and Redline has some additive anyway). I haven't had an issue with poop smell, but I have no carpet or side trim in the trunk to "retain" odor. I also open the trunk after each run to enable the heat from the cooler to escape, as it continues to run for 5 minutes or so.

My recommendation would be to buy the two bung, keep the vent and plug the second bung for a trial period. That way you don't have to drill a second hole for the vent if you don't need it :)

The lowest cost kit I could find was $1200, with no gauge. The list of parts I posted above is about $720 plus about $170 for the gauge. The kits use a thermo switch instead which is probably about $25, but I wanted to be able to see the diff fluid temps. These costs assume you have the 2013 Diff cover (I had already had already upgraded).

So a bit less than two arms and a leg ;)

But the real question is how hard do we track our cars and are we running hard for longer sessions. If so what's the cost of us loosing time at the track and then having to replace the Diff or seals :mad:

That's a great idea.
