As with all things when it comes to deciding what type of supercharger you actually use, there are many things to take into consideration. The table below gives a reasonable quick reference guide covering most characteristics.
|Ease Of Intercooling||Excellent||Fair||Fair|
|Fast Boost Rise||Good||Excellent||Excellent|
|High boost pressure Capability (>10psi)||Excellent||Good||Excellent|
|Low speed boost Capability||Poor||Excellent||Excellent|
|Power Loss Through Supercharger||Good||Fair||Fair|
|Simplicity of Installation||Excellent||Good||Good|
The main reasons for me choosing the Rotrex Centrifugal Supercharger were that of Size and ease of installation. Also I did not want to have the typical muscle car look with the blower protruding from the bonnet which would have been necessary if mounting a Roots or Screw in the V of the engine.
