This is correct GMC blowers with stock rotors have to much clearance. All they
will do is build little boost and lots of heat. This is the reason a good
blower costs so much, they have precision clearanced after market rotors. In
fact in applications where very high boost is used like on a blown alcohol or
top fuel engine they install teflon seals on the rotor tips. Although most t/f
guys now use screw type blowers not roots type, because they are so much more
efficient

I am no expert on the motors that these blowers come off of but from what I
understand they are not used to build boost in the engine just to move air
through them
I think that they are actually 2 cycle diesel engines
