Orcan introduce the Push Box
New from Orcan comes the Push Box, a specially designed part to improve engine performance and mileage. Used in prototype form by Alexander Hagberg to win the 2014 IFMAR 200mm Worlds the Push Box is made to become looped in the pressure line between the exhaust and the fuel tank and it makes for a more reliable and constant engine performance especially right after refuelling when running with high fuel levels as it prevents the engine from running too rich.
