Randy,

On my 235/320 I am running a Airflow Performance system and am very happy with
it.  I'm using their boost pump, filter, injectors, and purge valve and am very
pleased with its performance.  The purge valve is the best solution to hot start
problems.  

A picture of the purge valve is on my web page.

I'm using a SW8406R oil cooler available from Chief or Spruce.   The cooler is
mounted on the left side of the firewall and dumps hot air into the space just
above the retracted nose strut.  I made a fiberglass inlet "funnel" which takes
air from a NACA duct on the left side through a piece of scat tube.  You can see
the open scat tube on one of the web site pictures and the naca duct on the in
flight picture.  My oil temp runs 175 to 195, never goes above 200. Actually, it
should probably be a little higher.  In the winter I partially block the NACA
duct to get the oil temp a little higher.
