This supercharger head unit ships with a complete oil kit that includes 1 liter bottle of Rotrex traction oil, oil tank, oil filter, oil lines and is fitted with the Rotrex pulley hub adapter. URD does not have a pulley to fit this new supercharger yet but can provide the drawings for you to make your own pulley.
When it comes to horsepower, the bar is constantly being raised both in the OE sector but also aftermarket performance. As a natural consequence, a common request has been and still is; “a bigger supercharger”. Rotrex has over the past year been working on an upgraded version of the C38 size supercharger to meet this demand and has now reached a great milestone.
The outcome is the C38R – nearly identical size as a C38, but made for a higher power transfer and can support applications ranging up to 8 – 900 hp for a single charger setup! Current prototype impeller trim achieves more than 0.8 kg/s (105 lbs/min) and pressure ratio above 3.0! Final compressor performance will be revealed later. The design has passed automotive standards for SAE testing, similar to our standard range of C – Range superchargers.
As we are well aware that a lot of work has gone into design of applications supporting the C38 size supercharger, the new C38R has been made for a direct retrofit with identical mount dimensions. This means that customers already using the C38 will be able to upgrade to a C38R and gain up to 30% more power. Due to the higher power level, the input has been completely redesigned and can allow up to 12 rib poly – V profile belts, enabling a high level of system durability.
The next milestone ahead is actual production of the C38R and bringing it to the market.
