Werk Racing B7PRO features an all new crankcase design along with a long stroke piston/sleeve and turbo combustion chamber. 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 carberator has a smaller 9mm slide that improves air velocity just below the venturi insert. Hailed as fastest engine at the pro-series finals in Rockford IL.
