I think while there are lot of Nifty looking gadgets out there, you =
need to keep in mind that what may work well for a piston engine in =
cooling oil may not for the rotary. The basic reason is the rotary =
dumps approx 1/3 of its total waste heat load (not counting exhaust =
heat) through the oil. In fact, you can calculate the approx BTU you =
must get rid of through the oil.
=20
A 13B turning 6500 rpm with an 12.65 (best power) air fuel ratio will =
be flowing approx 16.1 gallons per hour. This equates to needing to get =
rid of approx 2650 BTU/MIN of waste heat through the oil cooler. Now =
using the old heat transfer equation Q =3D BTU, M =3D mass flow and Dt =
=3D temp difference, cp (air =3D 0.25)
Q =3D M*Dt*cp and assuming you heat up the air so that it exits 100 =
deg F hotter than it went into the cooler, then solving for the air mass =
M required =3D Q/ Dt*cp =3D 2650 /100*0.25 =3D 106 lbms/min or 106 =
pounds of air per minute.
=20
A cubic foot of air at sea level =3D approx 0.0765 lb/cubic foot. So =
to get 106 lbms/min you need to have 106/0.0765
=3D 1385 CFM of air flow through the oil cooler. Now that is a =
sizeable amount of air required just for the oil cooler at a modest =
power output of 160 HP. =20
=20
My point, is that, before you go spending your money and adding weight =
and complexity to your installation, sit down and determine what each =
element will do for you and whether it is really worth the money and =
weight.
=20
My person opinion is that it is hard to beat the efficiency of a well =
position oil cooler with adequate airflow through it.
=20
But, just my opinion. Certainly there are cases where a small cooling =
assist might make the difference and these things might make the =
difference. In some cases, space precludes the idea solution and in =
that case oil/water heat exchangers and other methods are called for. =20
=20
But, if you are in the planning stages, my suggestion is strive to get =
the right sized oil cooler positioned with good air flow.

Our 1992 Honda Accord EX Wagon has a oil to water heat exchanger =
that is sandwiched between the oil filter and the engine block. It is =
about 2=94 thick, the same diameter as the filter, and mounts with a =
longer hollow stud than would be used to mount the filter directly to =
the block. I have no idea of its capacity.
