Upgrades and Aftermarket - 7.3L EngineUpgrading and adding aftermarket equipment to your 1999-Up Super Duty or Excursion with 7.3L Power Stroke diesel engine. Please confine discussion of topics in this forum to those items that are specific to the 7.3L Power Stroke engine.
I just picked up a 12-71 roots blower last night. Has any one ever tried ditching the turbo set up for a roots supercharger? Looking at compressor maps for this blower, it looks like its most efficient at 2000rpms and ~17-20psi. I know I'd lose the intercooler and have fab up the belt drive and intake.
I have had similiar wild hair thoughts and remind myself that the truck is the toy hauler, not the toy...in my case
you can always run a water to air intercooler underneath of the blower and place the heat exchanger where the intercooler sits now. Then exhuast manifold or a simple elbow would be needed to close of the gap in exhaust flow. Oil, etc to and from the turbo too.

Keep the turbo on the 7.3 or upgrade to a larger turbo if need be. But leave the blower to gassers.. It takes alot of power to turn that blower.

Yeah, but they also have far less in the way of pumping losses, which the higher manifold pressure ratio really is a killer of hp too...not a static drag but as pumping loss and through reversion
Realistically a turbo will be far easier/cheaper as you don't have to do custom work or nearly as much.
