Today I got a chance to visit Gale Banks Engineering in Azusa, California.  Their facility is not only massive, but it is state of the art.  Working on everything from gas to diesel, they even work in marine and military applications.  Currently, they are bringing turbochargers back into the game and doing it big. This picture is of one of their testing machines.  This one is used to test engines for 400 hours at varying RPMs. For more information on Banks products visit bankspower.com.
