Diff Cooler Setup (pics)
I finally took some pics of my diff cooler installed and decided to post up pics in case anyone else was on the fence. I replaced my diff with an upgraded unit with the C6Z fluid pump built by RPM Transmissions and purchased through my friend John Page at 21st Century Muscle Cars in Carrolton, Texas. John was one of the first to inspire me to hit the roadcourse. As we talked about mods he was doing to my supercharged street Vette he sometimes spoke of how much fun it was driving a roadcourse...anyway I purchased another Vette for the track and the rest is like you know it....HISTORY. Back on topic...below are some pics of my diff cooler setup:
Looking through C5Z rear brake duct screen
Setrab fluid cooler with Setrab bracket secured to fender liner
Stainless mesh covering vent exit & backside of fluid cooler
C6Z fluid pump on C5Z diff
"Cooled" fluid return line
Fluid lines running to Setrab unit (I'll wrap these so they don't saw on my car)
The synchros in my tranny are well worn and when I have the cash for the tranny rebuild I'll have the C6Z pump installed and run another Setrab cooler on the passenger side brake duct. Presently I am in the process of adding a Setrab cooler in series with factory C5Z PS cooler. It will be located on front bumber core support hanging just behind the C5Z front screens.

Thanks!! Very cool!!! (no pun intended). 
What kind of temp changes have you seen?
Can the C6Z/C5 diff cover-pump be purchased?
Can you give an overall cost breakdown? TIA.

-Temp difference: my DIC occasionallly read "Transmission Temperature 279*" to "Transmission Hot"....I cannot quantify but I no longer get a DIC message
-I'm sure the parts can be purchased but I believe RPM Transmissions did some fabbing to adapt to C5 application
-I opted for the standard Stage 1 diff with 3.73 R&P with the pump being the only diff upgrade. Several respected racers, members & vendors advised that would be all that I need if I planned a seperate cooler. $1395 for the Stage 1 diff & $499 for the C6Z fluid pump installed. Links below.

Sorry for lack of exact details, it's been in service for a couple of events and I ran across these pics so I decided to post
