as I read all the posts about coolers and radiators I have been assuming that my 20B will require 50% more capacity than the 13b's.  Bruce just informed me that a stock 13B oil cooler should suffice
for my installation.  I read nothing that says this cooler is too big for the 13B, so I am surprised to hear this.  I believe him, and bought one this week, but still don't understand why this
should suffice for a 20B installation.  It will make things easier if it proves true.

Since there is only one 20B flying to my knowledge I don't know how he can say
that with any certainty. 

Tom Parkes, is your oil cooling all right?

A lot depends on how much of the 20B HP you use of course.

If Bruce is going on his car experience he is being misled.
A car requires X amount of HP regardless of how much HP is under the hood.
Road load for a car at 80 MPH is in a narrow range. 25 to 50 HP.

A Corvette is a good example. With 400 HP under the hood it gets down the
road with probably less HP than almost any other domestic car due to
it's low aerodynamic drag and moderate weight.
