Our approach to crankcase pressure and management is to assist you with the best products we have tested on the racetrack. We currently manufacture and have tested all parts on cars we build in-house and those we use on track. Due to the nature of making the crankcase system closed, with automatic drain-back to the engine’s crankcase, the OEM system must be disabled and/or removed. To do this fully, you must remove the OEM plastic tank attached to the back of the water pump, by draining the cooling system, using the provided FelPro gasket kits and replace the lost coolant which we do not provide.

The features of this Closed CrankCase system are:

  • Efficient oil separation technology developed by Patriot Motorsports USA & Improved Racing

  • Improved Racing .5L capacity CCR

  • Improved Racing CCR Automatic Drain adapter

  • SCCA, NASA, GridLife Approved: Improved Racing Closed System top adapter

  • Comes with stainless Steel Nutsert (NO NUTSERT TOOL)

  • Reduces oil consumption and emissions

  • Reduces crankcase for better ring and oil seal performance

  • Premium construction for durability under extreme conditions

  • At this time, due to variants of superchargers, intakes and designs. All purchases must communicate with us on your setup for proper fitment and parts needs.
