You've seen plenty of sports cars tuned up by John Hennessey and his HPE crew. Any manner of already-fast machine can and will be made faster by Hennessey. What about vehicles that are basically rolling bricks though? Don't worry... Hennessey can work some magic on those as well.
Take, for example, the 2015 GMC Yukon Denali. It's a 5,500-5,800-pound (depending on drivetrain) machine powered by a 6.2-liter V-8 engine. Said engine is good for 420 horsepower and 460 pound-feet of torque, which is certainly nothing to sneeze at. (That's a weird thing to do though, why are you sneezing at engines?) Regardless, it's certainly enough oomph to get the roomy condo on wheels rolling.
It's not enough oomph for HPE though, as you might expect. The team there now offers an HPE650 Supercharged upgrade package. The main portion of this kit is, as you've probably deduced, a supercharger. It's a 2.9-liter unit that's also paired with an intercooler, custom cams, new engine calibration, and the various Hennessey badges and serial-numbered plaques.
These upgrades work in concert to create 665 horsepower and 658 pound-feet of torque. Now the big rig can dash from 0-60 miles per hour in just 4.5 seconds. The quarter mile will be dispatched in just a tick over 13 seconds at a trap speed of 110 miles per hour. That's moving, and that's impressive.
If you've got a Cadillac Escalade instead of a Denali in your garage, you can get the same kit.
