John Urist and the Hellion Turbo team just entered an exclusive club of one with their 2015 Mustang GT being the first 6-second S550 Mustang.
In heads up racing at the 2017 Haltech World Cup Finals (X275 vs Hot Rod Class), John ran 6.95 @ 187 MPH on the first quarter-mile pass attempt and this was done lifting at 1000 ft!
This Hellion Turbo/Turn14 sponsored 2015 Mustang GT is equipped with a custom Hellion Turbo kit, 94mm Precision turbo, and a MMR Gen X Coyote engine.
