March 2013: Ford GT and a Dyno Pull
My Ford GT’s engine was modified in August of 2007. The Supercharger pulley was replaced with a smaller unit, and the engine’s ECU was re-flashed to take advantage of the smaller pulley. Then in April of 2008 I swapped the factory exhaust system for a Ford Racing/Borla system that mostly adds a deeper tone to the exhaust note while dropping about 30 pounds compared to the stock exhaust.
