Lunati Hydraulic FT Cam users..........

obviously...... they’re working for some people, otherwise they would be selling as well as they do.

They usually make good power up to the limiting rpm of the valvetrain...... which in most cases means......the lifters.

My experiences are that in most cases, the lifters give up before the motor has reached its “natural peak”(where the combo of parts would have peaked if the lifters has continued to function 100%).
I just don’t like the “mechanical rev limiter” situation I’ve experienced when using those cams.
