This is the updated Team Line .21 B7 Pro Competition Off-Road Engine from Werks Racing. The New B7 Pro features an all new crankcase design along with a long stroke piston/sleeve and turbo combustion chamber. The Pro-C line of engines now come standard with a Ceramic rear engine bearing, for improved performance!
The crankshaft is of a new design as well, in addition to new timing, the inlet has been lightened and ramped with an epoxy filler. The face of the crank of course is fluted and has been balanced with a tungsten insert. We haven't stopped there, the new 2-stage carburetor has a smaller 9mm slide that improves air velocity just below the venturi insert.
The engine uses a slightly revised lightened, low CG head design like that which was found on the existing B7. For the rest the B7-Pro only shares the carb pinch bolt, collett, exhaust gasket and head screws with the existing engine....it's all new baby! More torque, more mid range, more top end, not more fuel consumption! The motor screams and ironically it uses less fuel than the old engine. Based on testing this will be one of the fastest motors on the market! So if you really want to see what "Speed" is like, get your hands on the new Werks Racing Team Line B7 Pro!
All components are hand matched at the factory for the tightest possible tolerances guaranteeing the best possible performance. Part#WRXTL21PROC
