the gaps between the rotors decreases as air travels through the blower thereby decreasing the volume and compressing the air.

roots blowers like a 6-71 does not compress air it moves air and the stacking effect of air pushed into the manifold compresses the air. It is an air mover not a compressor. This is why a screw blower makes so much more power becuase it is an actual compressor. What you describing by this decreasing space between rotors is a screw blower not a roots.

Ok fair enough. Your getting pretty specific about the mechanism of how “boost” or pressure is created through roots vs screw type. Nonetheless your description about it is accurate.
I was mostly taking exception with the statement that they don’t make boost. You clarified it well however.

Back at it After a long time away, I started working on the 63 nova again. I have got most of the engine and trans parts. All of the bad sheet metal has been replaced. There is a 9 inch in the car. I picked up a polished 6-71. More updates coming. I put a threaded hole in the manifold for the cyclone iat. Hopefully running by Christmas
My buddy is building a 1957 Chevy Pickup w/ 22" billet wheels on bags with a 427 ls and an Alky Digger Blower, can't wait to see him complete it.
You're buddy have any vids of his car?
