I know the Evo 9 Mivec is VVT, and moves the intake cam via oil pressure. But does it use the twin lobe camshaft like in this youtube clip?

Or is the evo 9 mivec system something different from the older systems?

I tried searching, even on the web. couldn't find much.

Cheers, Mike

 

For evo9 It only varies intake cam timing, not lift.
