Actually the hybrid design explains the reason that the valvetrain is noisier on the S65 that most other engines with hydraulic valvetrains. The design sounds like it is really the best of both worlds, no adjustments but with the safety of a solid design!
I am now very interested in exactly how it is designed internally!

Correct
BTW this is our VT2 kit on a stock motor with RPM limit of 8600. Being a drift car it spends a great deal of time bouncing off the rev limiter.
