This video is a chassis dyno test being performed on a 1996 Supercharged Chevy Suburban! This thing really has some balls- mostly due to its 5.7 Liter, Whipple Supercharger.
These are a much better option than most after market turbo kits. They’re cheaper, MUCH easier to install and you can do it yourself on a Saturday with no welding. Remember to save your old trucks manifold, though. If you sell your vehicle you can put the old one back on and take the supercharger with you!
