RMW 30-74 Rotrex Kit (top mount version)

[Jan]

Rotrex superchargers are the latest in forced induction systems offering high efficiency, compactness, reliability and silent operation. The C range consists of the C15, C30 and C38 families.

With the unique combination of compactness and efficiency, the Rotrex supercharger leads the way in drivable, high performance supercharged applications.

Where the efficiencies of the Roots- and screw-type superchargers trail off at higher pressure ratios, Rotrex continues to provide the best thermodynamic efficiency under extreme conditions. This has been demonstrated on a number of high performance applications, such as the Twin-charged Koenigsegg CCX and Koenigsegg CCXR.

Compared to traditional centrifugal superchargers, the Rotrex unit offers superior boost at lower engine speeds due to its inherent capability to accommodate high speed impeller designs. This virtue is essential for compact applications requiring more torque at low engine speeds than is usually achievable with centrifugal superchargers.

The Rotrex supercharger is standard on the Ginetta (Farbio) GTS350 and the Ginetta F400, the Caterham-Lola SP/300.R , Caterham X330 and the Caterham V8 Levante as well as the Castagna Aznom and the MELKUS RS2000.

Key to the Rotrex supercharger's unique compactness, efficiency, low noise and reliability is its state of the art traction drive technology.

Great speeds and low noise are just some of the advantages of traction drives over traditional gear transmissions. Traction drives transmit power through friction forces between its rolling elements.

The Rotrex patented traction drive uses an elastic annulus with a small pre-span to secure contact between the roller planets and the sun shaft with a reasonable force. The patented "ramp effect" increases efficiency and reliability in the transmission by regulating the torque transfer capability on demand through self-adjusting planet geometry.

To enhance performance, the Rotrex traction drive uses a special traction fluid. These fluids are a new family of synthetic hydrocarbon oils and greases offering a series of unique performance advantages. Developed specially for its use in Rotrex superchargers, the SX100 momentarily increases viscosity under high surface pressure, enhancing the traction drive performance by securing the optimum friction between rolling elements while cooling and protecting the system.

This traction drive combined with the latest technology in centrifugal compression, characterized by high adiabatic efficiency and low noise, gives Rotrex superchargers an exceptional competitive edge over any other forced induction solution.








Here is the early intercooler design , it has changed slightly but you can see how much bigger it is than the stock intercooler. It is the highest quality intercooler made by Bell Intercoolers.




Here you can see the 30-74 mounted with Davies Craig waterpump.......you can see where they got their idea from How long before they copy me again with a Rotrex?




more pieces to the puzzle



throttle body sits in STOCK location



early version on Longboards car, it's slightly changed because his is running 55gal per min water pump
