2008 Shelby GT500 - Compound Interest - 1,200HP Shelby GT500
Tony Alm's GT500 Multiplies Its Power With Forced Induction Times Three
Regardless of this Shelby's intended street focus, the 9-second timeslips generated on its regular dragstrip outings required a rollcage that was up to the task-and complied with track safety regulations. Tony turned to Tig-Vision Welding (West Palm Beach, Florida) owner Dave Dodge for a 10-point chrome-moly cage that, despite being 8.50-certified, conforms amazingly well to the contours of the GT500's interior, and retains its street practicality. It envelops a cabin that is otherwise nearly stock, meaning it's not missing any of its factory baubles.
Saying he built the Shelby "to prove how far technology has come," Tony sums up the project as "the most fun car I've ever had ... It makes 1,200 rwhp, has ice-cold A/C, and still drives like stock."
For our part, we look at its innocuous, stripe-less exterior and wonder just how many rivals have been shocked and awed by this earthbound stealth fighter. Kind of fitting, given that the compound turbo/supercharging thing got its start in combat aviation.
