How Powerful is a LEGO Car?

Building and Testing a LEGO Technic Dynamometer! In this video, I build a purely mechanical LEGO Technic absorption dynamometer to test the performance and limits of LEGO motors and cars. The engineering and testing of this build was inspired by dynamometers used in the automotive industry. This video exists because of you. Many ideas - from the concept of using a differential to direct torque, to the idea of testing a LEGO motor to see if its power peaks at 50% RPM - were inspired by fantastic discussions in the last video!
