Thanks for posting this, Phil.

Darin,as Frank has mentioned,the air-cooled VWs dump their cooling air under the rear body valence into the wake.My boattail extended down to the top of the rear bumper and was completely open underneath to allow the original engine cover to be opened for servicing and allow the engine cooling air to communicate with the low pressure of the wake.I did get protection from the weather under there while checking the dipstick.As always,I could have done more,but budget and calendar conspired to end the work as you see it.----------- With respect to cooling,the drag reduction allowed the engine to operate at a lower load,thereby helping cooling that way.
