S-Power B7TT Factory tuned .21 racing engine
SWorkz have introduced their new S-Power B7TT Factory tuned .21 racing engine. It is a long stroke engine that offers quick response at low speeds with more torque in the mid range, with consistent idling. It comes in a conventional 3-port configuration which provides smoother torque throughout the power range. The engine’s crankshaft is DLC coated and has 2 tungsten counterweights contributing to a consistent idle and quick RPM response and it also has the latest back plate with surface treatment embedded in the cover plate. This is to reduce friction against the connecting rod and to extend its life. The crankcase of the B7TT has also been redesigned with a new boost port and a new exhaust port for optimum air flow. To accompany the engine there is the latest EFRA #2155 exhaust that has been tested and carefully selected to give your B7TT engine maximum performance and run time. It comes standard with a 80mm exhaust manifold. There are also optional 75mm and 85mm manifolds also available.
