DIY Roots blower: rotor profile drawing/dimensions
I set up this CAD drawing for spacing the rotors 2 inches apart. But when i actually make it out of wood, I think I will resize the dimensions so I can reuse my hole saws from before. Trying to find .518in radius I.D./O.D. hole saws would be too difficult... With this base drawing I should be able to scale it up to any size i want.

This profile does not produce a constant mesh and therefore it will produce very little boost and extreme heat which will cause detonation. A constant mesh rotor profile requires 324 arcs of varying radii per rotor whereas this design has 6 arcs with the same radius.
