Regarding the cooling capacity of "bar & plate" vs "tube & fin", yes bar and plate has traditionally had a better cooling capacity, BUT, there are alot of variables as you know. We are also using a different fin profile This design has worked flawlessly for 10yrs in one application and 5yrs in another. We are just making it over 2x nastier now.
Our core is 3.25" thick with the case inlet having a large radiused edge going to a 3/8" air travel space allowing the blower discharge to reach all parts of the core. Also, tube and fin allows the air to travel much better horizontally around the core than bar and plate.
Regarding testing, we should be dynoing the first week of Jan and results will be posted. We have already spoken with some engine builders that have your products and are interested in doing some back to back testing.
And Dustin, I genuinely think that whipple products are some of the best in the marine and automotive business. Obviously you guys have great resources, but like you said, a little competition is good for everyone!
