SP80211SP Spower Japan B7TT SPEED Factory Tuned .21 Racing Engine
SWORKz has introduced the new S-Power Japan B7TT SPEED Factory Tuned .21 Racing Engine, made by O.S Engines and based off of the popular OS B2104, but with the key differences being a non-DLC coated crankshaft, steel rear bearing and the cooling head. We consider this to be one of the absolute best value OS manufactured engines currently on the market, offering all of the quality, performance and reliability that 90% of racers are only ever going to need.
Tested and carefully selected to offer maximum performance and lower fuel consumption. The new S-Power Japan B7TT Factory Tuned is a long-stroke engine that offers quick response at low speeds, and more mid-range torque with minimum constant.
The piston/cylinder system is in the conventional 3-port configuration, which allows for smoother torque throughout the power range. The crankshaft is non-DLC coated and features 2 tungsten counterweights which contribute to a consistent and quick response at idle speed.
The latest technology rear thrust plate with surface treatment to reduce friction against the connecting rod and extend its life. The crankcase has been redesigned with a new boost port and exhaust port for optimal flow.
