Miateers,
I have been thinking about the purpose and effect of the cover that is 
attached under the engine.  I noticed that Phil Forsythe's car has it 
removed as does its sister ITE factory car.

The cover obviously precludes more active airflow in the engine 
compartment.  But it also seems that it might increase the air pressure 
under the car.  Removing the cover could allow cooler engine compartment 
air temperatures and decrease the pressure under the car (thus helping 
the car stick to the road better).  Although I haven't checked it out, it 
would seem to offer better access to the oil filter from under the car as 
well.

Anyone else have any thoughts or opinions on the subject?
