Forced injection is a simple concept, though there are many ways of achieving the same goal. Take supercharging for example. The earliest superchargers were repurposed diesel engine scavenging pumps perched on top of the intake manifold, turned by a pulley on the crankshaft. These Roots-style blowers are famous for sticking out of the hood. These days, many modern muscle cars are powered by centrifugal-style superchargers or low-profile screw blowers that allow for clearance under low hoods. You almost never see an old-school 10-71 poking through the hood of an LS-powered car

We say almost, because we just stumbled upon a video of a roots-style blower on an LS1 stroker V8. And as badass as it looks, it puts out some impressive horsepower numbers too.

The mix of old-school and high tech is an interesting one – while a big Roots blower might seem like a much more appropriate match for a HEMI or big block Chevy, the LS’ lack of a distributor in the way and factory heads that outflow the best hand-crafted vintage pieces make it a better fit than it might seem at first glance.

Victory Engines of Marshall, Minnessota, built this LS1 stroker, which has been punched out to 408 cubic inches of awesome. The 10-71 roots-style blower helped this sexy engine put out 843 horsepower and 749 ft-lbs of torque. That was running E85 ethanol and 9 pounds of boost. The video claims this is the first roots blower-equipped LS1 in America, and while we don’t necessarily think that’s the case, we sure had a hell of a time finding any other examples to disprove the claim. We’d love to see this bad boy revving on the dyno though. The idling video just won’t do. Hook us up, Victory!
