The majority of the Cobra's mods were added when Jay Hawthorne owned it. Injected Engineering out of Kennesaw, Georgia, gets credit for the Cobra's build and tune. Randy's friend Dane Parrott helps with mechanical issues nowadays. Since getting the Cobra, Randy's only had a few transmission issues, and he's replaced the clutch with a SPEC Stage 3+ clutch and flywheel. Prior to Randy taking ownership of the car, the Cobra spun the rollers to the tune of 649 hp and 635 lb-ft of torque.
