1808 - OBR Aluminum Power Stack / Velocity Stack Motors: G230RCBillet delrin version is now available and is half the weight of the aluminum version. OBR power stack is compatible with most aftermarket clamp on air filters. This is a bolt on performance item that will improve power on any engine that's stock or fully modified. We spent several months developing this stack on our in house flow bench and dyno. We've seen more power out of this design than any other stack that we have tested. Dyno graph can be found
