The VQ37VHR does yield higher power. Why else would it be the engine that it is if it would perform as a VQ35HR? Might as well just make it a VQ35VHR and forget the higher displacement. The problem with the G37 is that its additional power is offset by its additional weight [not particularly dyno related]. A 350Z with a VQ37VHR would be interesting (or lighter G37, which is not going to happen)

But the fact remains, it does not dyno more.

I'll believe it once I see a VQ35HR & VQ37VHR dyno in the same place at the same time, with the same conditions, and as close as other variables/factors as it can be.
As of now, ill stick to my belief until its proven wrong: as far as the engine itself, VQ37VHR > VQ35HR.

Shariff @ Forged dynoed both, a 350z HR and a 07 G37 and he even said the dynos were almost identical. These cars were dynoed hours apart from each other.
Oh and another thing..
VQ35HR > VQ37VHR due to weight especially.

I don't know much about how each of these engines itself weigh; can you please give me the info? I honestly haven't seen a thing about the VQ37VHR actually weighing [significantly] more than the VQ35HR, engine itself. Just then engine... since that is our little discussion here.
I hope you don't believe that the added weight in the G37 is because of the larger displacement... im sure you didn't mean this (I hope).

No one was talking about engine weights, the car weights a lot more.

So the 07 Coupe definitely is heavier than that.

That's one reason why I kept on specifically naming the engine and not the car... because my discussion (which I thought we were on the same page the whole time) was about the engine speficic. That engine could very well end up in the next generation Z (which is a discussion I don't want to get into because its just speculation).

So the 07 Coupe definitely is heavier than that.

These impressions were borne out at the test track, where the 335i was not only four-tenths of a second quicker to the quarter-mile mark with a 13.4-second run but also moving at a significantly faster clip of 104.3 mph. Meanwhile, 60 mph came up in just 4.8 seconds.
I thought they said the G did 13.3 at 104!! I'm confused but that seems to good to be true so I can only assume this was a big typo. I will assume they got a 13.8 quarter according to the above statement...

The 07 HR we dynoed did 237whp on its first pull on our DD, and managed to work its way up to 245whp after a half dozen pulls or so.
Our G37 dynoed 247whp-249hp with very tight consisteny between runs, so these engines appear to make very comparable power. GTM dynoed their G37at about 276-278whp on the dynojet, which reads about 10-13% higher than ours...so our numbers all appear pretty consistent.
Overall, I'd say there is on average, about a 5-8whp max improvement over the VQ35HR. I was a little dissappointed.
One last note. The G37 has the MOST rediculously restrictive exhaust I have ever seen, much more so than the 07 350Z. So I hope that a free flowing exhaust will really bring this engine to life.

When we install the exhaust on my car, I will take some pics and mic them up, in comparison to the OEM 03-07 Y-pipe.

very interesting. all this hoopla about it being such an effective exhaust system and now we find out it's not...i guess it just goes to show that louder than the previous models doesn't always mean better.
