GT-R intake manifold conversion progress?

The answer to VVEL is:
-GTM stopped R&D
-Uprev has torn down a complete VVEL block recently and has software which they say can adjust it but are still working on clearances and what exactly it takes to 'tune' VVEL and what it can do.

Yep, honestly there does not seem much stock wise we can tune out of VVEL, but it would be nice if someone would try to do some cams and throw them in and see if the system adjust for it.

Some of the mechanics from Baker Nissan, I know one of them, went to Dallas last week to study VVEL. He said that there is only exhaust cams in the head and that the intake system works more like roller rockers, with fingers letting in the air, etc... thats why you see that big solenoid towards the back side of the driver side head. That was his explanation, but we were drinking so.....

I assume that was Jason, he has torn an engine down once and taken a look, I was busy that day so I missed it.
The system sounds very complex but when he explains it I feel it should be easy to modify and expand. I think one of the issues is we just do not have enough support for this platform and the companies who are doing R&D are swamped with current projects.

We need to find someone with millions to buy into this platform and start paying for new R&D.

His name is Greg, he's a STI dude but he works on Nissans up there @ Baker. I was hoping you could give some insight. I know you know the Baker people well. I was hoping a company could just slow the whole VVEL system down tad, retard it or something, but it's obviously not that easy....ugh!

I know Greg, Green STi wrap currently.
The issue with adjusting VVEL is that the ECU has no control over it, the system is completely separate from the main ECU. This is what is causing all the problems with adjusting timing when tuning because the ECU shows it, but the VVEL system overrides any changes.

I am hoping that Uprev will be able to get some progress on their VVEL block they tore down recently and see some worthwhile results. I usually bug them once every few months to check on progress and anything new they have found.
