Variable Valve Timing in US

Of course you can get that kind of overlap without VVT. Profile your cams for it; You can tune the exhaust ( read back preasure and sonics ) and timing/AF to distribute power under the curve. I think the points being made regarding the fallacy in the magic world of "VVT adds power", is that, at this point, it is a miss conception, fundamentally. The addition of power linearly and the ability to migrate the band are semi overlaping, I believe this to be the reason this subject is always a source of debate.

I have dyno verified with an A / B test that the AVCS does not add any power what so ever after 6,000 rpm
Your stock WRX cams will yield the same HP on the top end
Somehow - it does add a significant amount of spool up in the mid range which makes it a very useful addition
The idel seems uneffected with AVCS on or off

However, we've been actively involved with their efforst. In fact, we finally received the first pre-production WRX Plug-in unit for in-house evaluation late last week. It came with the new Windows software too. I believe it is the only unit in the US right now. We're going to be giving it a thorough shake down for the next few weeks. If all goes good, the producting unit shouldn't be very far behind. No dates yet though so don't shoot the messenger.Cheers,

Heh,
I guess the STi will have variable valve timing, eh?
Is the cam timing changed through an ECU controlled solenoid? If so, anyone know from the existing Japanese versions, what affects cam timing? Is it solely RPM related, or is it also load or boost or something else related too?
