2,400HP 2015 Mustang GT Is Gunning For 270 MPH!

Allyn’s S550 is impressive! Making 2,300-plus horsepower on Ignite 114 @ 45psi of boost. At the Texas Mile in October of 2017, Allyn successfully piloted this beast to a 205-mph half-mile and a 257-mph standing mile. More upgrades to come, and we’ll only get faster! Thanks to Aaron at Nth Moto for helping us with the calibration, and to everyone behind the scenes who helped to make this possible!
