When a stock V8 simply isn't powerful enough.
There's a reason why people take their cars to Hennessey Performance. When the stock version just isn't powerful and loud enough, you really ought to do something about it. Life's too short after all. And Mr. John Hennessey offers a damn good solution. Take the 2015 Chevrolet Tahoe, for example. You could buy one at a Chevy dealer with a 5.3-liter V8 and call it a day. Or you could prove you've got a pair and drop it off at Hennessey's Texas HQ for a prescription that calls for a supercharger.
You'll thank yourself later. For anyone not convinced by this upgrade, check out the video ahead showcasing a drag race between a supercharged and a stock 2015 Tahoe.
