The time had come to put our engineer’s hard work to the test, a bench test to be specific. The bench test determines if our final transmission cooler will be a stacked-plate or tube-and-fin design. Given the fact that our cooler is over double the size of the stock cooler, we’re confident that either construction will cool better, but the devil is in the details. Aside from the cooling performance of each construction method, we needed to consider the pressure drop across each. The cooling performance of the stacked-plate cooler might be better than a tube-and-fin cooler, but if the pressure drop is too high, it will all be for nothing. To settle the debate once and for all we set up our bench-test rig and got to work.
You may be wondering why we’re bench testing the coolers instead of road testing
