PPPSSTTT, check my post on GT40s.com,,, I found that weeks ago,, where have you been...lol :rofl2:

In hibernation for the Canadian winter. I just woke up.

since the VVEL control the openning of the valve, adjusting this *magic screw* also move the minimum valve opening.
I say the valve will not fully close if you want that 300 duration *we are talking about thousand of an inch here*
this is probably why Nissan does not want anybody to play with those screw.

I should test it with my spare VVEL head ;)

edit; after thinking about the problem ,, it could be fixed with a different thickness of valve lifter. so yeah that 300duration could be possible as per what JWT discovered.

Even if it doesn't close all the way, I highly doubt you will need it closed anyways if you are going to muck with it much.

I am thinking about using a standard throttle body and controlling the VVEL stepping motor in relation to RPM/throttle. It's going in a supercar, so, I don't really worry about the pumping loss from the throttle body.

I can't image needing the valves closed all the way, all the time, unless you wanted to do cylinder deactivation on one bank, but on a cross-planed V8, it would make for some very uneven firing.

The valve must close in order to build cylinder pressure.

Are you scrapping your current project? What's the latest update on it?

The valve close all the way, when adjusted. What I meant was, they might not "stay" closed, as in 0 duration. It shows in the video, even with the full adjustment, the valve closes.
