Gearbox oil cooler

Recommended Posts

Has anyone thought of adding an oil cooler for the gearbox, has anyone done it?

I am considering it as I have my gearbox mated to a BMW V12 and I want to give it every chance I can.

Any thoughts on the added benefit?

The added benefit is an increase in oil volume, and getting it cooler, which would improve the capacity (to stress) of the gearbox. To what degree, I could only venture a guess.

Peace of mind is a big factor, but you have mated this 12 to the S1 gearbox?

I have considered this option, and it would appear to be pretty straight-forward, but some real figures would be in order.

How will you persuade the oil to go through the oil cooler? There isn't a pump in the gearbox as far as I know.

You would have to implement a pump (electric), setting it up would be easy, but determining the flow might be difficult, you could easily over pump it and lose the capacity for the oil to transmit the heat at peak efficiency.

Somebody somewhere was talking about some plumbing trick with the S1/S2 gearbox that would not require the use of a pump to circulate oil, but it was a passing conversation involving beer.............
