Hi Ed,
 
Don't know anymore than I read.  However, since you build these type of things, I would think it might be worth $14.00 to get the paper and find out.
 
   Anybody can made claims and there was not sufficient information there to form any sort of conclusion.  You can always tailor a design to give you the maximum in one area at the expense of some other area.  The real secret is having a design that does it all (or most all) well. 
 
   For instance, you can get a large deltaT with air flow through a radiator by simply  slowing down the air flow through it.  Now according to some folks that is the cat's meow.  However, due to the slow mass flow you won't be removing much heat from the radiator/engine which is the real objective.   So balancing the warring aerodynamic  and thermodynamic aspects of heat transfer in any design is the real secret (in my opinion)..
 
You mention seeing us seeing a heat exchanger at Tracy's.  I presume you sent some of your work there for viewing at the Rotary round up??

Dear Ed
       Being that I respect you opinion and advice what do you make of this mat. is it worth buying the tech papers to show people at air shows what has been found technically not opinion (the pope Paul) on this subject.
                                                                                                                   Regards
PS one of these oil/water coolers is at tracy's house already                                                                                                                Ed Klepeis

For some of you considering a coolant/oil heat exchanger in your installation might want to explore this items more.  Claims a 5 times greater performance than your regular coolant/oil heat exchanger.  Not certain that this is anymore than an experimental prototype or concept.  But, for you to decide.
