[QUOTE="JimIII@JDM, post: 874493, member: 736"] Actually.....I have all 3 in house so I took some measurements and noticed a few differences. The Original Whipple Heat Exchanger was much smaller than the AFCO unit. Also is was a single pass rather than a dual pass. The Whipple measured 23 1/2" across, 10" tall, and 1 3/4" thick. The AFCO was massive compared next to it, measuring 26" across, 15" tall, and 2 1/2" thick. The extra surface area and thicker core are going to be a massive improvement cooling. As well the larger tanks on the sides of the core and the fact that it is dual pass means the coolant stay in the Heat exchanger twice as long while air passes through the fins to lower the coolant temp. The New Whipple is about the same size. Its only 23 1/2" across, but 18 1/2" tall and 2 1/2" thick as well. But the fact that it is taller doesnt even matter because that extra surface area is hidden behind the bumper not getting any air flow. Actually the Whipple HE sits about 5-6" below the bumper line causing a good chunk of the Heat exchanger not to see any air flow. Now the AFCO unit is almost 3" wider which covers more "useable" surface area behind the grill. This could prove to make it better. The tanks on either side of the core are much smaller then the afco tanks as well. I would be that the AFCO and Whipple hold about the same amount of fluid. When running fans the AFCO design is much better! The fans sit behind HE not in front of it block critical Airflow like the Whipple does. We only prefer fans for heavy traffic conditions or off road slow pace driving. When your moving and you have open airflow going through the grill the fans aren't helping you. Only when air flow going across the heat exchanger becomes stagnant do fans help. We use them on our Drag race cars to cool down in between runs. Now real world testing would be to do some datalogging on the same vehicle in back to back conditions testing all the options. From what I can tell you dollar to dollar is the AFCO is a much better deal and if not just as good maybe more efficient than the new designed Whipple unit.
