sadly, as in lots of elements of managing modified engines, demo and error is in regards to the only way to obtain your perfect combination.
as an alternative, centrifugal superchargers work very best at the top within your engine's RPM array, building comparatively small Strengthen at reduced revs. Irrespective of that, they will make extra Strengthen overall than optimistic-displacement superchargers, resulting in more horsepower — just in the smaller part of the rev assortment.

it can be crucial to know the main difference as they offer distinct Advantages and electricity delivery designs.
each the Roots-type and the dual-screw classify as “favourable displacement” superchargers because they each offer a constant electrical power Improve at all RPMs.
