Werks Racing TL21B3-Pro Race Engine
Werks Racing have introduced the newest addition to its ‘Team Line’ of engines, the TL21B3-Pro utilizes an improved case design featuring additional stiffening ribs around the sleeve area to control heat expansion, while a new long stroke design, coupled with a race proven 3-port design, provides the perfect blend of strong torque and aggressive top end. The B3-Pro features much of the same factory machining normally only found in higher priced hand modified engines which includes extensive casework improving the primary boost port as well as the transfer ports. Fuel flow is further improved on the sleeve by machined teardropping of the transfer ports as well as a series of crankshaft alterations and combustion chamber changes that include a new fluted crankshaft with revised timing.
