Ok here are some answers to some questions mentioned here:

1. Yes, it was a Dyno Day.
2. We had 2, Nismo 370z
3. Can't recall, but we had about 6 or 7, 370z touring with bolt ons...

When i arrived to the shop, 1 370z had already pulled 308 WHP, don't remember what bolt ons he had. Next was my buddies Nismo. His car is a stock as mine, nothing done to it. He pulled 310 WHP.

More and more 370z with bolt ons, kept getting on the Dynos, all broke 300WHP mark... the highest 370 i saw that day made 328 WHP i believe.

Then my buddy in his Nismo installed the Test pipes. Then they put him back up on the Dyno.... he ran 332 WHP and 252 Torque if i recall correctly. That an extreme 22 HP gain from just the test pipes.

After few cars, they put mine on the dyno. First pull, on 4th gear, it made 326 WHP if recall it correctly. After of idling a little bit, they made a second pull putting the car up to 330 WHP and 250 Torque.

Everyone was amazed... and couldn't explain why my car was making that number. The only reasonable idea mentioned by performance guys, was that it may have something to do with the fact of how aggressively you drive your car. If you push you car to the limits on daily basis... car may learn your driving or some **** like that.... well... I thought it may be the case, cause i don't baby my car... i already took it to the Drag Track too... so i push my car most days im on the road... If this is not a reason.... I don't know what.

I will post the graph on monday, I got a scanner at work. You don't have to believe me. But guys from this forum were on that Dyno day with me, they saw what happened.

Don't hate the player... hate the game!

hhhmmm i like how you contradict yourself
you dont know who made 328 which is the highest you saw
but your for sure your friend made 332 hhhmmm interesting
just thought id point that out

!

It was obviously one of those "Feel Good" Dyno days since everyone posted such high numbers. Explains why everyone was "amazed".

Since a Nismo is 350 AT THE CRANK it is impossible to generate the numbers you did without the Dyno calibration faking it. Probably uncorrected numbers rather than standardized SAE readings. I had a corvette that dyno'd at 442 (Uncorrected)...Plug in the industry standard SAE corrections for temp, humidity, elevation etc and it was 410......There Ya go! I wouldn't go around bragging on those numbers cause people who know how this stuff works (and how easily it is manipulated) will just laugh at you...

What did you run at the "drag track?"

uhh dont ask.... it was my first time going to the track. I had only given 3 runs, for $40.

I kept screwing up every run. My best run was 1st run 13.8, with reaction time .6xx... i started of easy, not flooring 1st gear.
2nd run 14.1 dues to spinning wheels at the start... 3rd run 14.xx due to misshift...

Hate to say it, but i think the numbers were bad, due to my poor driving.

about the correction... i didn't know what it was.. but corrected HP was 327 for me...uncorrected 330

here is revised info:
Uncorrected - 330 WHP @ 7500 RPM
Corrected - 327 WHP @ 7436 RPM
Corrected - 250 ft-lb @ 5500 RPM

Again, will post graph, first thing in the morning.

Ok, well i guess if everyone so skeptic about the numbers. I will do everyone a favor, and do another DYNO run somewhere else...
Then will post the results to make everyone happy with lower numbers... or upset again with higher numbers! lol

Regardless of your "poor driving," it just seems like everyone is running similar times. E.T. is a relatively meaningless gauge of power-output, however. Your trap speed is the biggest indicator of the power you are making, where I'm willing to bet it's right in line with all the other unimpressive runs we've seen on the forum. Hey...hate the game, right?

HP is not a measure of how fast your car is. Acceleration times are. Still...you don't have a "330 WHP" car.

Ok, i don't have 330! I hope you can sleep better!
I am done with this thread...in fact... i'm not even gonna make another post, giving you guys information. You need it, go get it yourself.

Is that the way the rest of the vq37's dyno plots look? IMO, that's not really something I'd want to have at all...

No. That's just along the lines of what you get out of a Mustang Dyno in terms of charting. The scaling and plots differ from the accepted "standard" DynoJet readout to the point where you can't really compare the two.

Again, this is why dynos are merely devices to tune, not measure power. They give you the ability to repeatedly run the engine in 4th or 5th gear all the way to redline in a safe, controlled environment where you can monitor and thus tune the engine's vitals.

One could program a dyno to have a stock Toyota Corolla put down 400 WHP.

Here is what a realistic "330 WHP" looks like on a Z. This is the chart of Semtex's car with all the Stillen bolt-ons on a DynoJet:
