just wanted to see what you guys would do... getting ready to rebuild my berk jg with a A2. currently running an A, top speed 71mph at 5300rpm. going witha A2 im thinking its going to drop to about 63mph and hold around 4800-4900. with a B cut, maybe 76mph and about 5600-5700rpm. does this sound about right? nothing is going to be done to the motor, just a pump rebuild. thanks guys
