Hey more power to ya but my 20 year old technology currently outperforms current technology in the fuel mileage region. My fiances car has cam phasers and can only return 32mpg. 35 if im driving. You are def correct in the longevity. I'm seein cars at my shop that have 150-200k miles on them and the valve covers never been off. Nothing wrong with that. But on the other hand I'm starting to see variable valve timing codes come up.
Probably the earliest cam phaser used is the 2.0 zetec. That is used just for egr imitation. Ive been to classes on cam phasing and variable valve timing so I know how it works. I'm just saying I'm not impressed In the least. When they start getting in the 28:1 and higher afr range I'll be sure to edit my post. I'm more impressed by pgfpros work with his work on his talon. 9 second in the quarter mile and 50+ mpg capability. THAT'S impressive.
