Rotrex C38 Centrifugal Supercharger - C38-91, 110mm Diameter

The Rotrex C38 centrifugal supercharger is a compact bolt on solution for increasing engine performance. They have been developed to provide the ideal combination of power increase with reliability and low noise. Unlike turbochargers these Rotrex superchargers are driven from the engine so the power and torque curve is more linear and predictable. The C38 range of superchargers are ideal for larger engines from 3000cc to over 6000cc with power outputs up to 630 Bhp.Hugely versatile supercharger suited to a wide range of engine size and powerIncreases power and torque throughout the rev rangeUnsurpassed power to size ratio compared to other supercharger manufacturersIdeal for engines from 3000cc to over 6000cc with power outputs from 300 to 630 BhpSelf contained oil supply system so no need to tamper with existing engine oil systemRotrex centrifugal superchargers use a patented planetary traction drive system which takes power from the engine crankshaft to spin the compressor wheel up to 90,000 Rpm. This creates higher boost at the low to mid Rpm range for massive improvements in acceleration. This system also means the supercharger is vibration free, quiet and reliable in operation.To enable easier fitment of a Rotrex supercharger to a vehicle they have been designed with a self contained lubrication system which includes a dual action oil pump, filter, hose and specially developed traction fluid. A separate oil cooler with -6 JIC male fittings is required to complete the oil system, suitable options can be found HERE. To further aid fitment the compressor housing can be rotated in 60 degree increments for optimum outlet orientation.The Rotrex C38 superchargers are available in 5 different models to suit different power outputs and within those 5 ranges there are several options of pulley size which determines the supercharger speed. If you are unsure of which supercharger will best suit your application speak to your mechanic or contact our sales team who will be able to assist.To calculate the correct pulley diameter apply the relative information from the table below to this formula ensuring the maximum supercharger RPM is not exceeded: Max engine RPM x Crank pulley Diameter x Supercharger drive ratio ÷ Pulley diameterRotrex C38-61 Compressor MapRotrex C38-71 Compressor MapRotrex C38-81 Compressor MapRotrex C38-91/92 Compressor Map
