The higher the boost & rpm, the greater the Twin Screw advantage
* PATENT PENDING
1. Short runners (less restriction, higher air flow, higher peak HP) vs. long runners (higher restriction, less air flow).
2. Front inlet kit size is limited by underhood space around the fan and requires more restrictive and smaller turns. Also
supercharger entry openings are smaller 80-90MM range vs. 148-168MM for Kenne Bell rear inlet.
3. Kenne Bell rear inlet is “full open” to rotors with no driveshaft in front of a rotor. Some front inlets actually have the driveshaft located and rotating – inside the inlet manifold opening or adjaecent to it.
Talk is cheap and opinions are many. Factual data can only be realized
through controlled testing. This is the only Supercharger Dyno that
we know of capable of accurately testing the high boost, RPM and
power consumption (400HP+) of the larger 2L, 3L & 4L superchargers. Our
choice was to either “guess” at this data as others do with “little” 120HP electric motor dynos or develop our own high HP dyno.
400HP (NA) or 800HP (Supercharged) engine drives torque meter which
accurately measures supercharger power consumption, CFM, boost,
temperatures and RPM of Kenne Bell and the competitions superchargers and inlet systems.
