Lockheed SR-71/J58 AG330 Start Cart

The AG330 start cart was developed exclusively for the Lockheed SR-71's Pratt & Whitney J58 turbojet engines. The cart used two Buick Wildcat V-8 racing engines, each of 425 cubic inch displacement. Together the engines produced over 600 horsepower and were tied to a common gear box to deliver torque through the starter drive shaft to the J-58s. The aircraft engines had to be run up to at least 3,200 rpm for ignition.
