Stock I made 292WHP SAE in ~70F weather. Keep in mind manual transmission makes ~10hp more than AT to the wheels. Also I have non-sport package, so my brakes, wheels and tires are all smaller and lighter, ironically giving it more power to the wheels than sport.

What about the torque curve do you think is strange that it doesn't match other VHRs?
My attitude is that no matter how many dyno charts and information you provide, someone on the internet is gonna argue that "something smells fishy", "i call BS", "it's fake" or that I somehow have the only 3270Z that didn't come with a VHR engine or whatever the hell you are saying and it gets old.

My header thread
here has stock vs header+tune dynos, but
they were done months apart so the temp difference was about 20degrees. That's all the data I got and something people will just have to deal with.
I've seen now that the ambient air temperature does make a big difference on these cars. SAE and STD correction factors are designed to account for that difference, but the engine power output fluctuates beyond what those equations account for. Looking back, if the header before/after dynos had been done on the same day, the graphs would probably show a lot less gains. Still even if the gains were only say 20HP instead of 32HP, I would be perfectly happy with that.
The "before y-pipe" dyno from this thread was the same mod configuration as my "after headers" dyno in the other thread but the days/temps were different(80-85F for y-pipe runs vs 70F for after header run) so it was already about 9HP lower from that.
I originally posted STD corrected charts in the first post of the header thread. But since everyone cried foul I posted SAE version here:
First mod: PPE Headers... +35WHP
