The cowling has one air intake below the spinner. I am planning on mounting an RX 7 ('89) oil cooler and evap. core water radiators under the engine with the air inlet feeding air through the radiators. The oil cooler and radiators would be side-by-side at about a 30 degree angle to the inlet with the high end toward the front of the aircraft. James has stated the inlet area is 51.25 in-sq. and the outlet is 63 in-sq. I believe the inlet can be enlarged by about 50% if necessary. Anyone want to comment on this arrangement before I spend the $900 for the cowling? Thanks, Dennis H.
