There is no magic here just an expansion tank for when the grease gets hot and expands up the vent tube. I run a diff cooler setup to control the temps which get up in the 285 deg F range on track with the Torsen. Ford lowered the fill level which I don't agree with, I fill to bottom of plug hole to keep lube on all parts during cornering etc. I use Bob's , but the Shelby version will work just as well.
