Ken,
Could the Cadillac, or Corvette, vacuum pumps be used to provide pressure
as well as vacuum.  If so, the pressure could be used for preflight
checking of the cooling system.  Also, my Lancair ES has need of a pressure
pump to inflate the door seal.  Am I dreaming or is this a real
possibility?  -- Mark

I think you need about 30 psi to pressure test the cooling system.
According to this smog pump curve the pump is only good
for less than one bar or about 15 psi. It is more of a volume device 
than it is a pressure device.
