Introducing the new Racetec 3P .21 3 Port Race Spec Engine!!
Over 12 months in development! Designed and developed in the USA! Over 100 years of combined RC nitro racing experience went into designing, developing and manufacturing our first engine! Power and mileage has been optimized for todays demanding off-road conditions. When we started this project our #1 goal was to provide a great engine at a forgotten price point. This price point shouldn't require corners to be cut, and we didn't!
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 carburetor. A long low speed needle ensures solid idling, smooth transition to high rpms and solid return to idle. While maximizing 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 optimized 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. Available in 4 colors: Black, Blue, Red, Pink
The boost ported backplate increases throttle response, connecting rod cooling, mileage and power! All wins!
