Latest video update about the freevalve technology. The part about having a 12-14:1 compression ratio was pretty interesting. I assume they're able to have such a high compression ratio because having complete control the intake valves means they can easily run the engine in a Atkinson cycle (lowering the compression ratio) and are therefore are able to run to take advantage of a high compression ratio when the engine isn't at risk of knocking or detonation?

Any mention of rev limits for the Freevalve system? Historically, it's been the Achilles heel of these types of systems.

In the first video they say the system can do 20k RPM.
