300 WHP Big Turbo Ford Fiesta ST - One Take

We have lots of experience with bolt-on parts for the Fiesta ST after our COBB-Tuned long-termer, but this is a horse of a different turbo. This Fiesta ST has an upgraded turbocharger, and a massive list of aftermarket engine and power adding parts resulting in an almost unbelievable 300 horsepower at the wheels. It's an absolute riot to rip through a canyon. Check out the Fiesta ST on Wheelwell! https://www.wheelwell.com/profile/54e...
