There could have been well over 1 Million horsepower from all the high performance machines both inside and out of the Las Vegas Convention Center last week at the 2009 SEMA Show. Aside from the seat of the pants the only way to measure the amount of thrust that an automobile can make is with a dynamometer. It is not every day that you get to see the inner workings of a dyno, how the tires turn a large metal drum which then spins an electromagnet which through the beauty of math and science is able to calculate just how much power realy is making its way to the pavement. So it was quite a treat to see this display from Mustang Dynos at SEMA exposing all its inner workings for all of the crowds to see.
