Thank you, everyone!
It would seem that lubes designed for the everyday street-driven car aren't=
up to the challenge of racing our hyping diffs. =C2=A0I thought the folks =
at Mobil would have done better, but apparently not enough. =C2=A0I've take=
n all your inputs into consideration and going with the Redline Shockproof =
(lightweight) oil. =C2=A0I'm also thinking of bolting on the aluminum cover=
of the 4A IRS diff to get a little extra capacity and perhaps some better =
cooling, although the added thickness may offset the higher rate of heat tr=
ansfer through the metal. =C2=A0Will do the math.
Your insights are much appreciated.
Regards,
Phil GottRed '65 4A, #114
