I liked your addition of an air scoop. That's probably important if 
the over-tranny cooler is going to do anything at all. Where are you 
measuring the oil temp? It's got to be somewhere IN the engine to be 
meaningful.

Those adaptor plates have been around for awhile, but I've never seen 
one personally. If they are just a simple plate that allows the 
installation of a parallel system of oil coolers or cooler/filter, 
which is most likely, then they should give a bit more cooling and 
allow for a bypass, but not full flow filtering. Adding quick 
connectors will reduce the bypass flow even more.  

If they put the coolers in series, then they will give full flow 
filtering and double cooling, but the pressure drop they introduce 
comes after the pressure regulator valve, so the delivery pressure to 
the bearings will be less. Quick connectors in the lines will 
increase the pressure drop in this system and apply even less flow to 
the bearings.

All things considered, I don't see much in this option that 
recommends it. There really is one good way to install full flow 
filtering and that's done by the method in the book I mentioned. 
Because of the Type 3 fan housing, the plumbing is more difficult 
than on a Beetle, but it can be done, and the outcome is just as 
good.
