Anyone have any experience or thoughts about the Oil coolers offered
by Griffin that are built into the radiator.  Apparently an oil
reservoir is added to the tanks and some of the radiator tubes are
dedicated to oil.  Tried to get hold of Griffin but they are not open
on weekends. If adequate, these would really clean up my installation
with both the radiator and the oil cooler in the fuselage.   Jerry

I would not mess with them Jerry. Probably not enough cooling capacity for the 
rotary. Fully one third of the rotaries cooling is done by the oil.
Besides, Griffin is the outfit that supplied Chuck Harbert with an oil cooler
that split and caused an in flight fire. The box it came in looked like
Chinese card board to me. The stock Mazda RX7 oil cooler is a very fine piece
of work and works great on a NA 13B  when plumbed with AN line.
