The original (one and only) Issigonis-designed 'Mini' had its radiator mounted 
sideways into the front left wheel arch.  There was no ducting on the 'input'
air side.  The argument was that the wheel arch is always a low pressure area, 
and its 'suck' was better than _any_ duct's blow.
 
If you check the underside of an ur-quattro, both the oil cooler and the 
intercooler vent at the rear into a wheel arch.  I suspect the 'suck' effect's 
lowering of pressure behind the devices is more important than the 'blow' 
effect of what little ducting is in front of them.
