Twin Turbo Mustang GT 500 in 5.0 Mustang & Super Fords:

 

Compound Rapture - GT500 Twin-Turbo

Hellion's Turbos And Shelby's Blowers Are A Match Made In Horsepower Heaven

Travis Franklin of Gear Heads Automotive and Performance checks the fitment of the Turbonetics low-mount, 61mm turbochargers that will make boost magic happen when they start feeding the factory supercharger in his '08 Shelby GT500. Travis picked up his low-mile, still-under-warranty Shelby for a song, and was 100-percent ready to set it up with Hellion Power Systems' Shelby GT500 Twin Turbo setup--a performance mod that is about as radical as they get right now for GT500s. Give that man the "ain't skeerd" badge he deserves!
Travis uses SCT's Advantage III tuning software and XCalibrator 3 flash device to create and load a power-churning tune into the PCM of his newly compound-boosted Shelby GT500. The addition of turbos does not affect the engine's ability to start and run, but there's no way the hammer can be dropped the way it should be until you've got a good, pump-gas tune and safe air/fuel ratio (11.7:1) at wide-open throttle, which can only be achieved by having an experienced tuner like Travis Franklin dial it in. As an authorized Hellion Power Systems dealer with an in-house test Shelby, Gear Heads is working on developing custom SCT dyno tunes that are specifically calibrated for the new GT500 twin-turbo systems it sells.
