I bought a finned cover for mine but I haven't installed it yet because it
interferes with my panhard bar. But I checked my temperatures with some
temperature sensitive paint and got about 250 degrees F. Hot, but not
terribly so. I also drained the oil to see how it looked, and it was fine.
It may be that the way mine is set up it doesn't slip much, or it could be
that Peyote's relatively light weight helps. I had planned to add a pump
and cooler if necessary, but so far I'm OK. I'm running the version of
Redline that's okay for LSDs--I don't recall what that is.
I doubt the diff will run cooler later--it's the clutches sliding that
makes all the heat. That will continue unless you change something.
Peyote is transformed with the LSD. I used to spend a lot of attention on
getting the back wheel to hook back up in tight turns. Now I just nail it.

Subject: Limited-Slip Diff questions
Just installed a plate type, LSD - 4.1 fully rebuilt diff in my street
TR250 (just testing - will install in TR250 racer eventually)....I have
seen other comments that they run hot. Boy do they run HOT - after a 25-30
minute drive you would burn your hand on casing. I am running the TR6
diff cover for added lube capacity.
Questions:
Synthetic vrs. Mineral base lube ?? (I have synthetic gear lube in there
now)
Limited slip additives - yes/no ??
Will diff run cooler after some "break-in" period ??
Should I add a finned cover with additional capacity ....or run pump & oil
cooler ... or both ??
Any comments ?
Thanks - Jack Coffey
