The 2-cycle GM Diesels sometimes had a turbo feeding the Roots, making it a compound supercharged engine. Being a Diesel, this allowed them to throw more fuel at it and make crazy HP (actually, torque) for the displacement. The DD engineer who came to EPA with one said sizing the turbo was a B!tc#.
Initially the Roots blower was just a cylinder filler for the Rootes two stroke Diesel.
The motor was designed flat to fit under the truck cab.
Dodge bought out Rootes and threw it all away, putting their motor in the cab with all of itīs 140 decibels.

like this one installed where the bed used to be on a mini-truck that we saw at Bville...except there didn't used to be an intercooler!
Since I was uploading to YouTube I added this one too. Sorry about the white wash on the color, apparently my camera on video mode can't compensate for the extreme brightness of Bonneville.
