Variable cam timing

"what about a synchro-type system where the amount of slip between the
driving motor (driven from the crank) and the drivenmotor (connected to the
timing chain / cam gear itself) can be varied, giving a variable cam timing
technique? it could be extended into having different timing for intake &
exhaust, for dohc engines. The motors I thought of using would be some sort
of induction motor, to eliminate the use of brushes."

Ooh, you're so close.........hint: you don't need the motor;)
