i swapped the xd cam in my beta 1.i had the 1.8 cam in. the xd cam sucked in performance.the car sounded lovely.but it loct a lot of torque.the 1.8 had my engine pulling harder than the xd cam. in my opinion,the 1.8 cam is alot better for the beta 1 motor.i would like to know if there is more to this cam.
