The F-11 design brings added elements of performance and safety to the racing world.On all the Fowler F-11 style units, the front bearing housings have three inches of billet material that are press fit into the rotor case and push the rotors back in the case allowing the air to come and load the front of the rotors providing a smoother transition of airflow and providing more boost and cooler air as the air does not get so beat up entering the blower.
This bearing plate design increases the strength considerably over the common dowel pinned bearing housings normal to most supercharger designs. The rear cover is also captured in the same way. This design also benefits repeatability of rotor location. As these units are overhauled, the doweled design tends to wobble out the bores and the rotors find themselves misaligned over time, which can cause supercharger malfunction.
Blower uses precision caged roller bearings in the rear and precision ball bearings in the front as well as double lipped teflon seals for superior sealing.
This blower can be ordered in a standard 60 degree rotor or a 120 degree hi helix rotor depending on the use. RBS can help the customer choose the best supercharger for your application.
