I have given this high temp. running some thought and over the winter lay up will try and fabricate an NACA type of air duct into the floor pan to funnel cold air from under the car up and over the BB.
Have a look at the floor pan of a Lotus Elise MK1
Nuff said.
I went and made a couple of primitive vents using the prop cover that seems to keep my BB a bit cooler and quieter in the warm weather and long runs.
