Dragncar, Ever heard of a guy named, Norm Drazy, The PSI Supercharger Brain/Originator? Same guy whose superchargers were banned in Pro Mod as being 'Too Good".
Norm came to see me one time in Dearborn, Michigan. He had this Pro Mod Supercharger strapped on a two wheel cart and ran it up to elevator to my office.
This was years ago when he was banned everywhere. So he figured that if he could sell Ford on purchasing a smaller version vs the Eaton "baby" supercharger he could make some money and help Ford out at the same time.
Dragncar, George's little baby 177 supercharger (believe you called it a "puny nothing blower", sounds about right by the way, is a correct comment. Even George's and Jim's 8-71 superchargers are "nothing" (your words) compared to the stuff Norm was trying to sell to racers at the time. Norm made a video of his PSI blower vs a 14-71 blower years ago.

From the article "an alcohol engine running the PSI blower (385ci displacement) made 1,260 horsepower at 28 pounds of boost — the same as a 14-71 blower (552ci displacement) running at 36 psi. The difference was lower manifold air temperature (85 vs. 150 degrees) and less parasitic drag on the engine."
So take anything George posts about superchargers with a grain of salt.
Not sure if Norm Drazy is still out there, heard he walked away for a while and was spending time with his wife. Just be nice to George, He is a Bracket Racer.

Art Whipple has made a nice income selling his version of a screw supercharger to the Brand X Guys for their stangs.
