Polaris Slingshot Stage 3 Performance Cams by DDMWorks

The Polaris Slingshot Stage 3 supercharger cams are designed specifically for the DDMWorks Rotrex supercharger kit on the 2.4L Ecotec. This intake and exhaust camshaft profile was designed to have a moderate lope at idle and offer an extended RPM range beyond what stock cams can provide. The emphasis of this profile is on midrange and upper RPM power. These are higher lift, and much longer duration camshafts than anything else available and can not be matched by simple reground cams. Installation of these cams on a Rotrex supercharger can gain 30+hp at the wheels (scroll down to see dyno charts).

Headers, 2.5” exhaust, custom supercharger tune and 95mm pulley are required to get the most from these cams. Although stock valve springs can be used with these cams, we do not recommend going over 6500RPM with stock valve springs with these cams. If using the stock valve springs, we strongly recommend replacing the hydraulic lash adjusters at the same time as the cam installation. With upgraded valve springs the engine rev limiter can be set to 7500RPM.
