Think of the possibilities

Interesting, I can see the horror stories now....Crank trigger, ECU, etc. screws up and you don't just bend A valve....You bend all of your valves.

The cool thing is, no more cam swaps. Just tune it on the dyno! WOW that would be a real PITA saver!!!

Different lift/dur for dif rpm ranges was my main thought. Essentially your cam specs can change for every x-ammount of rpm increase. With the right tuning you could create a monster with one smooth power/torque curve

Good point! The other thing that scares me with higher compression head with less P to V clearance is this statement:

"the valves default to a partially open position"

What happens when you have an electrical problem and loose power to the valves? OUCH!!!

dont use a ford alternator :lol:

This idea keeps on coming up every so many years. If F1 keeps putting more sanctions on thier engine building it might be many years before we see this in passenger cars by then I will be flying around in my hover car beside the Jetsons.

The same thing that happens when an ohc motor snaps a timing belt lol catastrophic failure

I think the "default" statement reffers to if neither the opening or closing side were activated. As in partially open is where it sits when nothing has been activated. So really while the motor is running there would be no piston to valve clearance issues.
