Which supercharger is best for your LS engine? Do you want a modern style Whipple or Magnuson? How about a centrifugal like a Vortech or ProCharger? And what about all of us who love the look of an old school roots blower? Can I bolt a 6-71 to an LS and make real power too? The answer is yes. Yes to boost. Yes to more power. Yes the LS engines love it. We all know that junkyard LS engines make big power with a turbo setup, and that’s just because boost is good.
Whether you make boost with a roots, a centrifugal, or a screw doesn’t actually matter. They all make power.
So check out the video, with full dyno results, from Richard Holdener below as he puts them all through their paces on a couple of different LS engines.
