REFLECTOR: Engine compartment oil cooler

[Richard Riley]

I'm doing a little work on a friend's Velocity XLRG.  It's been running 
very high oil temps.  The reason may be that the very large oil cooler in 
the engine compartment isn't getting any pressurized air - it's just 
sitting in front of the forward right cyl, standing in the still air of the 
upper cowl.

I'm thinking it should get pressurized outside air to one side, then 
exhaust from the other into the engine compartment.

I'm figuring on doing a plenum on the back of the cooler, and getting 
pressurized air from the main plenum on top of the engine, or adding a 
scoop to the bottom cowl and running a piece of SCAT to a plenum on the 
front of the cooler.

Is there a standard way for this to be done on the XLRG, or do they 
normally have an oil cooler without any airflow?
