There is a high risk of fire or explosion if the engine backfires. Weiand Features Exclusive CAD designed 2 lobe rotor provides maximum boost pressure efficiency - no Teflon to wear out. Thick rotor walls prevent rotor growth under high RPM, allowing use of tight clearances. Thick, wide supercharger mounting surface on both manifold and case resists twist and ensures a good seal. Low profile design-fits under most hoods.
Heavy duty bearing plates use ball bearings instead of needle bearings for extended bearing life.
Front and rear bearings are lubricated by oil reservoir. Integrated tensioner arm design eliminates possibility of belt failure. Total tooth count should be at least 105 and no more than 116, for big block Chevrolet engines.
