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.

Meaning Japanese engineers are effing smart!

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.

I wish Sam@GTM would comment in this thread with a progress report

And maybe a price point. $1000? $2000?

AlphaSnacks · 11-17-2011, 01:54 PM

I always knew and accepted that the Z34 was significantly faster than the Z33.

DarkZide · 11-19-2011, 11:26 AM

Wait...so GTM was saying their "preliminary" results showed signifigant gains when tuning VVEL and then they just gave up?

Doesn't that sound odd to anyone?

There is more than just finding the results, you have to be able to reproduce them without extreme cost.
I believe at the time GTM was using a stand alone ECM system to adjust VVEL which most people will not want to buy and then pay to tune VVEL. Where as Uprev is working on being able to use existing ECU/software to control VVEL creating a cheaper solution with the same results.

NYBladeZ · 11-19-2011, 12:37 PM

So as it stands, it an be done but it is extremely expensive and labor intensive.
