Rotrex C8 released

January 2011

Rotrex is proud to announce the release of the latest breakthrough for the patented Rotrex traction drive technology, the Rotrex C8.


The C8, which has been developed especially for extremely compact applications, features a traction drive with an outer diameter of 91 mm (19 percent less than the already very compact Rotrex C15).

The Rotrex C8 features the well known whisper silent traction drive type as the other members of the Rotrex C family, but in an even further simplified design and will thus be even more economic than our larger superchargers.

This makes the C8 ideal for applications such as smaller fuel cells, subcompact cars, unmanned aircraft and small displacement motorcycles. The C8 has been released with a 240,000 rpm red line, a max air flow rate of 0.065 kg/s and as such can provide sufficient air for applications up to approximately 80 hp, depending on the actual application.



After an extended period of meticulous development Rotrex can now offer our clients the granddaddy of the C38 range: The C38-91.

December 2010

Targeted specifically at those clients that want to enjoy the refinement and sheer acceleration of a Rotrex application but need that extra grunt and sheer power, the C38-91 features the best efficiency of the C38 range and flows 11% more than the C38-81.

Even at the very upper end of the power band, at a verified flow rate of 0.63 kg/s where no Rotrex has ever gone before, the measured efficiency of the Rotrex C38-91 is 65%, making sure your high power application will not unduly load your engine with thermal strain.

The C38-91, which shares the same basic drive dimensions and features a compressor housing only 8 mm longer (axial dimension) than that of the other members of the C38 family, serves up a peak (isentropic) efficiency above 75% and has a wide high efficiency island, guaranteeing forceful acceleration all through the engine rev range, as well as great gas mileage when you are not 'on the throttle'.

Rotrex C38 in Maserati action with NOVITEC TRIDENTE.

July 2010

Applying the Rotrex C38 in a highly refined setup, NOVITEC TRIDENTE releases the Maserati Quattroporte with a rated power output 590 hp / 434 kW and 572 Nm of peak torque.

The specialists of the German company applied the Rotrex C38 to the 4.7-liter eight-cylinder four-valve engine in order to boost performance efficiently: Maximum boost pressure is limited to 0.35 bar, sufficient for ample performance increments.

After the engine conversion the Italian luxury sedan delivers high-end performance figures: Rated power output of the Quattroporte S jumps from standard 430 hp / 318 kW to 590 hp / 434 kW at 7,300 rpm. Simultaneously, peak torque grows from 490 Nm to 572 Nm.

A water-to-air intercooler with dedicated water circulation ensures healthy operating temperatures for the engine and the NOVITEC TRIDENTE SPORT compressor conversion is rounded off by a custom intake manifold and larger injectors. Newly calibrated engine electronics ensure optimal power yield, longevity and compliance with strict Euro IV emission limits.

Horex GmbH launches the new Horex motorcycle

June 2010

How does it feel to ride a charismatic motorcycle sporting a powerful supercharged VR6 engine?

Well, time will let us know for sure, for such a motorcycle is exactly what German company Horex GmbH is setting out to produce from late 2011 onwards.

With a design which clearly is a nod to the classic Horex bikes, the latest generation of Horex' is yet again demonstrating uniqueness and courage to go against the mainstream, implementing solutions that, while having been inspired by the automotive industry, have never been applied in the world of motorcycles and are thus adding to the charisma and allure of the new bike.

The ultra compact Rotrex C15 supercharger is applied in order to ensure efficient, smooth, predictable and powerful boost, completely free of any lag in response to actual throttle positioning and as such the ideal companion for motorcycle applications, where power is transferred so directly to the palm sized traction surface of the rear tire.

For further information on the new Horex bike please visit www.horex.com.

Power Enterprise does it again!

January 2010

For the second year in a row, the Japanese distributor of Rotrex, Power Enterprise, has won a prestigious award at the Tokyo Auto Salon.

While last years award was received for the high tech high power quad charged dual Rotrex C30 Nissan GT-R, this year the award for best product in the Eco department was received for Power's Rotrex charged Honda Insight hybrid, running on LPG gas.

The kit of Power Enterprise demonstrates that respect for the environment does not have to come at the expense of driving pleasure: The stock 88 hp of the 1.3 liter engine is, by the application of the Rotrex C15-16, spinning at up to 142,000, increased to 130 hp, applying only 0.4 bar of boost.

Another true testimony to the efficiency of the Rotrex and the engineering prowess of Power Enterprise!

Roehr launches the Rotrex supercharged Roehr 1250sc

August 2009

Rotrex is proud to have been chosen by Roehr Motorcycles to be the OEM supplier of choice for the Roehr Motorcycles product line. Cleverly taking advantage of the ultra compact, efficient and robust design of the Rotrex C15, Roehr Motorcycles has achieved 180 hp from the Harley Davidso n V-Rod type engine.

At the heart of the Roehr Supercharging System lies the patented Rotrex (C15-60) centrifugal supercharger unit. This supercharger provides the highest levels of efficiency and performance in a compact, light weight unit. This unit weights only 6.4 lbs. and is no larger than a typical small car alternator. Combined are a high efficiency, highly developed "Turbo" centrifugal compressor section, mated to a patented planetary roller drive mechanism. This drive mechanism provides an extremely high step-up ratio of 12.7/1 as well as very low noise output, low wear and excellent reliability.


Power Enterprise wins the "Best Modified Car of the Year" award at the 2009 Tokyo Auto Salon

January 2009

In an impressive display of technical savvy and inventiveness, Power Enterprise, the Japanese distributor of Rotrex superchargers, successfully demonstrated its engineering capabilities at the 2009 Tokyo Auto Salon, taking on and beating all other designs by being awarded the "Best Modified Car of the Year" award with their quad charged Nissan R35GTR, featuring twin Rotrex C30-94 units.
The target of Power Enterprise with this project, which is scheduled for general release by May 2009, was extreme but well controllable torque over a broad power band, making the already fearsome GTR a thoroughly frightening track weapon: More power and torque would, through the application of turbo chargers, either have led to increased turbo lag (twin large turbos) or much higher thermal load (quad turbos).

Not so with this setup, in which the twin OEM turbo's pre-compress the air going into the twin Rotrex C30-94's that in turn, through reduction of the work load as seen by the turbo chargers, remove any turbo lag and complement the turbo's over the entire power band, creating a staggering torque curve available with near- instantaneous response.
