I am planning on getting a clutch type LSD some time this spring and I am thinking about how to properly cool the diff. Even though the finned diff covers are easier and simpler, I do not think they are sufficient to properly cool a clutch type differential.
I am interested in this differential cooling kit by VAC:
Comes with pump, cooler, lines, fittings and a thermoswitch which will automatically turn on/off the cooling pump.
Has anyone played with this or other diff cooling kits on the E90?
How loud are those pumps?
