Not sure what you mean about not seeing big gains with headers. In the 370Z forum, it's common knowledge PPE's and Z1 (momentum replicas) make great power, even comparing to testpipes. I made about 35whp avg between runs (30whp comparing highest of both) with PPE's and CBE while still running a cat. This was without tuning and busted O2 sensors.
Just for reference, there is no mrev manifold for the VHR. You could have just gotten the named wrong, but just in case... we have the M370 HR manifold and the modified Z1 VHR manifolds. M370 has a slight advantage up to 3-4krpm. The Z1 manifold isn't far behind on the bottom end, but is stronger up top by a sizable margin.

300 on a dynojet. Baselines were 260-265. Tuning and having O2 sensors working correctly would have made a big difference. I don't doubt another another 15whp was in it. I picked up 16 more whp with intakes and NST pulleys with the same O2 issue and no tune.
I didn't find out my O2 sensors were flip flopped and miswired until I went FI and sent it to GTM. I have pics of the fail. I'm now making 550whp
410 lbft with GTM's twin supercharger kit at 11.88 lbs.

my car was the highest dyno numbers my tuner has seen for a 7 speed auto..
im hitting 320hp/268tq
but then again its just a dyno numbers don't mean anything but just to compare what you gained from add-ons..

Sorry if this has been explained but I thought the G37 gets 328hp stock?

Thats Engine horsepower at the crank, you lose horses through the drivetrain.. so down to the wheels is where these numbers are coming from.

There are no factory freak mass produced cars. They are all built the same. These are not hand built cars where someone is tweaking them for max performance.
Dyno results can vary by something as simple as tire pressure so I would never get too carried away (good or bad) with dyno results.
Also, dynos need to kept in proper calibration and that costs money. Most shops probably don't spend the money to keep their dyno set up properly.
Just wanted to bring a little reality into the conversation.

yea but remember the AWD G's are only that if the rears slip, if not they drive as a RWD car, Remember I made 300 WHP on my X coupe NA and 457 WHP with the Stillen SC. Those numbers are right in line with the RWD guys. Give or take a few only cause the AWD's are autos
