The dip in torque and HP at 5,200 RPM is consistent with every M96 engine we test with F1 Vario Cam.. The only way to get rid of it is to eliminate the vario cam and change the intake cam, something I have been working on for 3 months now and just got finished Friday :-)
Now we make as much power at every RPM as we did with vario cam, without the constant changing over on and off throttle and the shock loads that presents to the IMS bearing.
