A new reverse rotation version is now available by special order. Contact info@URDUSA.com for more information.
When it comes to horsepower, the bar is constantly being raised both in the OE sector and 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! The current prototype impeller trim achieves more than 0.8 kg/s (105 lbs/min) and a pressure ratio above 3.0! The 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 the 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 the actual production of the C38R and bringing it to the market.
The is the only supercharger in the Rotrex lineup where the pulley must be purchased separately. URD does have a full line of pulleys to fit this supercharger and can be found here:
