Slingshot Rotrex Supercharger Kit by DDMWorks

  • Regular price $4,900.00

The DDMworks Rotrex Supercharger Kit for the Polaris Slingshot boosts your 2.4L Ecotec Slingshot from the stock 155hp at the wheel to a tire shredding 280hp at the wheel (330hp). This power can be accomplished with only 8-9psi of boost with most aftermarket exhausts for the Slingshot. Simple installation, reliability and instant power make this one of the best options for adding big power to your Slingshot.

When designing any supercharger kit, the supercharger itself is one of the most important parts of the system. We choose the small and compact Rotrex C30-74 supercharger because of it's light weight and highly efficient compressor.  Unlike other centrifugal superchargers that only spin 35-55,000k RPM's max, the Rotrex spins the compressor impeller to an amazing 120,000 RPM's safely, producing more midrange punch and top end power than any other centrifugal supercharger. This efficiency is because of the 
patented high-speed planetary traction drive found only on the Rotrex supercharger. The high speed impeller design is essential for compact engine applications like found in the Slingshot that require more torque at low engine speeds than is usually achievable with most centrifugal superchargers. 
The Rotrex supercharger uses a unique traction oil circuit that is completely separate from the engine, no drilling or swapping oil pans required like turbo kits. The system is self contained, offers up to 98% drive efficiency and has both an integrated oil cooler and oil filter. This dedicated oil circuit ensures that the supercharger is always lubricated, cooled and transfers torque efficiently for a long, long time. With this unique traction oil setup, low noise and high reliability are achieved, which is perfect for cruising down the highway or twisty mountain roads. 
Using CAD (Computer Aided Design) we designed a unique, automatically tensioning, belt drive for the supercharger kit that simply bolts to the front of a stock engine. The belt drive in our kit is completely independent of the stock alternator belt and allows the engine to be ran and driven indefinitely in the unlikely event that there would be a failure of the supercharger belt. This means that you could continue to drive your Slingshot even with a belt failure, instead of leaving you on the side of the road.
We worked hard to make sure that the installation of this kit can be done by the do-it-yourself-er, no drilling into your engine for oil supply or returns, a truly simple bolt on kit that adds to the excitement of the Slingshot! We are available for tech support during the installation by email, phone or even text messaging to make sure you get the job done right. This kit was extensively road and dyno tested for over a year of development to ensure safe and reliable operation.
