For comparison:

ZR1: 27#

What I intuit from this:

The VVEL isn't very smooth.

no, it is there due to the fact that the vq37 is very unbalanced.

Good point, + the post above yours.

How does this impact long-term durability? I haven't really been looking, but do VQ37's have a rep for popping at a certain mileage or just randomly? I was under the impression that they were anvils, except for some '09's that used a bit of oil until Nissan fixed the issue.

No rep for that at all....on the other hand, there is only one guy I know of past 60k.

I don't think Nissan would put out a motor that would be popping at 80k, but it probably depends how you treat it. You can't change the laws of physics, and the noise alone let's you know what is going on at high rpms. When you realize that is in spite of a boat anchor of a flywheel....I'd just sell it as the warranty runs up.

I would imagine the engineers figured this into the design. As long as it remains close to stock it shouldn't be an issue. And I would bet that as long as the rotating parts stay stock it still won't be an issue.
