[Fot] IRS Diff Cover

[malaboge at aol.com]

Oh I'm so jealous of that finned alum diff cover!
BUT, a more practical question...do you think the most oil capacity, or directed internal oil dispersion is more important. (Already using RedLine heavy shock proof oil).
Some history...
The Duke of Oil, our 4A has melted a set of the poly mounts (see a previous pic someone else submitted...same deal here) in  a normal sprint race. So, diggin thru the pile-o-parts I find I have an early one piece TR6(?) diff cover that is pretty much a square reservoir in the back (the oil reservoir area looks about like the reservoir on the 2 piece 4A diff cover), and another later (?) one piece cover that directs the oil flingin around in the diff toward the ring gear and has more fins on it. However, the later more heavily finned unit holds about 8 ounces less fluid, but it directs the oil directly onto the gear and has those additional fins.

I would really like to skip the oil pump and cooler setup in the back of the car, but may have to go that way anyhow.

BUT,
Has anyone had any experience with running the later, smaller oil capacity but more finned and directed oil units? And how would it compare to the larger open chamber cover?

If not, who has installed a pump and cooler back there? What did you use for a cooler and where did you put the outlet and inlet on the diff...and why?

Usually in hot water myself...this time oil!
