Owner of this wicked quick S550 Mustang keeps throwing power at it and it continues to reward him with new PBs.

Stewart already has a few test runs in the wicked Mustang Cobra Jet 1400 under his belt with impressive results.

A stock block, 17 PSI of boost and a 6-speed stick shift transmission make this Holley controlled Fox a rocket.

Ford’s Mustang Cobra Jet 1400 makes its public debut with some seriously amazing statistics and more in the tank.

While it isn’t a true Cobra, this snake look-alike still packs plenty of bite with a fully built and procharged engine and a track-ready roll cage.

With all these turbo and supercharged S550 Mustangs running around, we forget what an all-motor build is capable of.

C7 Z06 may have more motor, but it doesn’t have the GT500’s superior power and winning speed.
