Designing and handling interfaces
Check if other systems such as carbon canister and EGR need to be adjusted to work
properly under boost.
It is imperative that there is an air filter on the inlet of the supercharger. If this is
neglected, there is a risk of damage to the supercharger from objects being sucked into
the inlet and damaging the host.
Not using an air filter which can remove particles larger
than 20 microns voids warranty. An open filter arrangement will in some cases give
induction noise from the impeller. To prevent induction noises, use a closed filter box as
seen on most OE applications.
It is important to position the throttle body downstream (after the supercharger) to avoid
excessive vacuum, potentially collapsing hoses and damaging the supercharger.
Positioning the throttle body upstream (before the supercharger) voids warranty.
To maintain air cleanliness, it is important to position the air filter where external clogging
can be prevented. The air filter should be mounted where it cannot be covered or sprayed
with water and mud. If the air filter gets clogged, the air flow is restricted and will cause
a pressure drop, resulting in temporary loss of pressure and air flow. The filter used for
the application must be able to last the oil-maintenance interval found in Section 4.4.2.
Do not make unnecessary sharp bends in the air ducting as bends will cause pressure drop
resulting in loss of output.
Using a minimum of bends in the inlet and outlet hoses will
significantly increase the adiabatic efficiency of the supercharger and increase the success
rate for reaching the desired point of operation.
Also, some applications require various
sensors which could potentially interfere with the air flow and decrease the adiabatic
efficiency.
All air ducting on the inlet side of the supercharger must be of a material that does not
collapse and restrict the airflow under vacuum. A Partially blocked air filter will result in
significant vacuum which can cause surge or easily collapse a soft hose. Rotrex urges the
customer to minimize the use of soft materials in the entire air ducting system.
Rotrex also recommends hose diameters for both inlet and outlet to match the
supercharger compressor housings inlet and outlet diameters. For specific diameters see
Section 3.1. If the inlet ducting, disregarding our recommendations, requires many bends,
sensors or narrow pipe diameters, extensive application testing is required.
Hoses, pipes, filters, valves etc. must be fastened with proper clamps to prevent air
leakages in the system. To ensure correct tightening torque, use the recommended
specifications delivered by the clamp manufacturer. Also, Rotrex recommends contacting
the clamp manufacturer to help choose the optimal clamps for the application.
