Any advantage to having more duration on the exhaust cam, than the intakr cam,
I noticed the skunk stage 3's and Toda D,s both have more duration in the exhaust.

 

i dont see any way it would iimprove performance. ebcause if the exhuast side is open while the intake side is open, then that would mean that air is getting out. all i know is that duration is a no no when going turbo

 

more duration equals better breathing at high RPMs! thats for NA cars...

 

Duration can vastly improve N/A and FI'd cars. It just means the valves are open for longer.

What you don't want with a FI'd car, is overlap. Duration is what can create overlap, but they are not the same thing.
