THE BEAST: GM’s ZR1—the year-old king of Corvettes—should be enough car to humble any speed freak: 638 horsepower, 700-plus gut-pummeling pound-feet of torque. But to some that just ain’t enough-—those folks make a pilgrimage to Texas supertuner John Hennessey’s shop to get their ZR1 hopped up on goof-balls. Hennessey swaps in a freer-flowing exhaust, tweaks the supercharger, and reprograms the engine’s computer for more speed. The end result is a tire-killing smoke machine that rips to 60 mph in just under three seconds. America, fuck yeah!

HELIO’S TAKE: I have a ’Vette Z06, but this is just a huge step ahead in performance, cornering, and speed. Sure, its interior is less refined than, say, a Ferrari’s. But this is supposed to be outrageous. You just want it fast and loud, LOUD, LOUD
