Al, I was envisioning a cheap 110V 3HP squirrel cage fan sitting on the 
ground under your wing with some flexible ducting going from its outlet 
to the oil cooler inlet, with a sheetmetal "manifold" to give you some 
area to duct tape it to the underside of your wing.  Should work good 
for static testing.
