Designing and handling interfaces
It is recommended to have at least 150mm unrestricted flow before and after the air
mass meter to avoid problems with the readings caused by turbulent flow from
recirculation valves and other ducting that may cause turbulent air flow.
Inlet restrictors are considered a constructive change of the supercharger unit and
influences its characteristics. Incorrectly designed inlet restrictors can also create dynamic
forces applied directly to the rotating impeller wheel and may cause damage to the
supercharger and/or reduce lifetime.
Using custom inlet restrictors voids warranty
. In case
it is deemed mandatory for the success of the application/project, please contact Rotrex
directly for assistance.
