Installation Notes
Typical lifetime: max. 50 h according to Bosch Motorsport standard validation program |
For application with severe conditions and/or high volume, please, contact your Bosch Motorsport counterpart in order to define the most appropriate validation program. |
An external cooling can contribute to increase the performance. It will only be effective if the incoming air is 30°Kelvin cooler than the ambient air. Otherwise, the restriction of airflow will negate any cooling benefits. If these conditions are met, the cooling air should be distributed over the center axis at the rear of the alternator for optimal cooling. The alternator fans are not able to generate negative pressure. It is possible to use external blower to support the alternator. Debris at alternator cooling area can reduce cooling effect. This could also shorten the alternator service life. Installation without rubber mounting. |
