600-Plus HP Mustang Shelby GT500 Is More Than Just for Show

A craving for more fun continues to drive one Utah man’s love for Mustangs.

Every Mustang owner who sets out to customize their car share a common goal – make the vehicle more unique than it was when it rolled off the assembly line. Sometimes, it’s something as simple as swapping out the wheels for something with a bit more road presence. Then, for others, that idea eventually evolves into something much bigger, which clearly is what happened in the case of Jeff Streeper and his 2011 Mustang Shelby GT500, as detailed in KSL.com report.

From the sound of it, the Utah resident kind of jumped right into it, with one his first mods being a smaller supercharger pulley, an aftermarket intake system, a custom tune job, and special performance gauges to get a more accurate on his Mustang’s power upgrade.

Apparently, the work didn’t add a lot to his Shelby’s power. but after competing in a half-mile race, it did spark Streeper’s interest to crank things up a bit. His next mod came in the form of a 2.3-liter Gen 2R supercharger. The Shelby owner followed that up by adding a larger heat exchanger to help keep things cool, after adding the bigger supercharger.

Later came a set of 56 pound-an-hour fuel injectors to handle all the power the Mustang now cranks out, which now cranks out about 625hp and 633 lbs-ft. of torque, more than a 100 horsepower more than the stock model.

In Streeper’s case, the wheels were one of the last mods made to his Mustang. But they’re far more than just those star-appeal additions we mentioned some people opt for, earlier in this post.

Nope, for Streeper, the wheel mods included a set of 15-inch wheels and drag radials. And given that Streeper stresses the point that his Mustang is all about having fun, we wouldn’t be surprised if there are few more performance mods on the horizon.
