Great video!
This is Kerry Torres, Instructor from United Technical Institute - Phoenix AZ - on his own time.
He knows what he’s talking about. I hope he does one on induction systems, compression ratios, power adders.

A couple of years ago Hyundai made that worrying about camshaft duration a thing of the past, they invented a variable valve duration system they have in a production car. It is clever.

Ron great to see you are lurking! Hi buddy! I am trying to educate myself a little as I am working with an engine builder to select some parts. The really had thing is heads and cam timing while trying to predict torque curve and limit hp to what the gearbox will be happy with. My preliminary target is 540-560Hp and 400-500ft/lbs from 4000-6000. He believes this is very doable and we may need to trim Hp somewhat. We'll see!!!!!!
