When it comes to horsepower, there is never enough. Or is there? Hellion Power Systems just pushed the envelope even further for the S550 platform.
Hellion’s in-house Street Outlaw Mustang is a turbocharged 2015 Mustang equipped with an MMR Gen X Billet Coyote engine that has been boosted by a Precision turbocharger. This is the same vehicle that the company races in the NMRA series.
So what did it take to claim the current title of world’s most powerful 2015-2017 Mustang?
