Recommended Supercharger

Medium Roots (1.9L - 2.3L) or Medium Centrifugal

Roots: Instant boost, less efficient at high pressure, great for street/strip
Twin-Screw: More efficient than Roots, internal compression, premium cost
Centrifugal: Most efficient, boost builds with RPM, similar to turbo powerband
