Racetec 3P .21 3 Port Race Spec Engine

Klinik RC, through its Racetec brand, has released its 3P .21 3 Port Race Spec Offroad engine. Over 12 months in development their first engine release is proudly designed and developed in the USA! Power and mileage has been optimised for todays demanding off-road conditions. Starting this project, their number one goal was to provide a great engine at a forgotten price point.  This price point shouldn’t require corners to be cut.  The Racetec 3P has a 3+2 port design in a die-cast crankcase.  High quality bearings ensure long life and smooth RPMs. Reliable and durable.  The Racetec 3P features an alloy/composite 2 needle carburettor.  A long low speed needle ensures solid idling, smooth transition to high rpms and solid return to idle.  While maximising mileage along the way.  A built in heat isolator ensures consistent needle settings and no heat soak. 6.5mm venturi is included.  The combustion chamber has been optimised for 20%-30% race fuel.  By producing big power with lower nitro content, mileage can increase dramatically.  The billet cooling head is lighter and more thermal efficient than cast counterparts and is available in black, blue, red or pink.
