General Information
The KSE Tandem pump is designed to produce optimum flow and pressure on both the power steering and fuel at 50% of engine RPM. Because the engine pulley and water pump pulley being used can vary in diameters, no one set of tandem pump and water pump pulley ratio will give a final 50% of crank RPM to the Tandem pump. Ratios that are too fast or slow will produce performance problems which can be attributed to the pump shaft speed and NOT the Tandem pump.
The crankshaft and water pump pulley used in conjunction with this kit must yield 50% of engine RPM at the Tandem pump, or the Tandem pump will not optimally perform and the combination should be adjusted to achieve the 50% shaft speed at the Tandem pump.
