Thanx guys!
As Valentino said... we live, we learn.
I sure did learn a good lesson, on how nasty people get when they learn that someone else is better or more succesfull then they are, regardless of the truth.

Forgot my Dyno sheet at home, will have to scan it tomorrow.

:roflpuke2:
I just do not know how to respond, really you want to make a statement like that.

don't...
oh and take your HP number of your sig, its wrong.

This thread gets even funnier, really, people are trying to help you and teach you about your car and you make comments as per the one I quoted. Yes this is a forum, yes there are going to be people are blunt with you, but read what they are trying to say (past any insults or criticism) and learn.

I did not know much in terms of power for this car, but before I went for my baseline dyno I read around the forums with other members and got a feel for what I expected. Even with your car, which has a factory exhaust and tune you could easily see what to expect and understand what you got might not be 100% accurate.

You still don't get it, do you??......:shakes head:

Duly noted!!! Thanx!

No I got it, and ready to close this thread.
Let's leave this thread behind. I will post the updated numbers from more accurate DYNO. Again thanx for all the info.

:icon18:

For the love of God, man, get your head out of your a$$.

No, but it should be just a tad closer to the Cayman S; was that not the Z's performance target. FAIL in this test big time. IMO, it should have been a bit closer to the GT500, but obviously Ford's time on the chasis along with the gobs of more power spank the Z.

To your point, good new on the feel of the car, but it's numbers should have been much better. I bet a tuned Base+Sport with about 100 pounds of weight savings will put the Z in a better light. Nismo, not so much for.

Good points. I do think a regular Cayman is a much better comparo for a Nismo than a Cayman S, and I also thought the regular Cayman was the benchmark, but maybe I'm wrong there. The Audi should not even be in the test (wtf were they thinking, why not drop a $300,000 Ferrari in while they are at it), or at very least they should have included a Nissan GT-R!

I'd love to see the same test at a track like Lime Rock. Laguna's straights give enormous advantage to the big-HP beasts, imho.

The MT test was Apples and Oranges....and bananas...and grapes....:shakes head:

And MT, imho, is the worst car mag out there................................

The test was to compare cars they considered to be "driver's cars." The GTR is far from, arguably with the most diluted and artificial feel of any modern performance-car.

"Laguna's straights?" By no means do I consider myself an expert on Laguna with only 80 or so laps under my belt, all of which HPDEs as opposed to countless of competitive laps around Infineon and T-Hill, but I have yet to encounter an actual straight-away on that track. Perhaps you have a little more insight than I do, but Laguna does not provide an advantage to "big-HP beasts" by any stretch of the imagination. The track technically does not have a straight, nor is there a portion where you can wind out more than two gears at wide-open throttle. But, again...perhaps you know better than I do.

I have never driven Lime Rock, but if memory serves me right, its layout is much more advantageous with added power as average-speed on Lime Rock is significantly greater than Laguna. Regardless, the Nismo's second-to-last lap-time is abysmal, considering the live-axle 3900 lb. GT500, 3900 lb. Camaro SS, 4300 lb. automatic, 4-door XFR, and joke of an open-diffed 135i all soundly beat it, disregarding the other performance cars.

Of course it is. I'm sure your opinion would be no different if the NISMO trounced the competition and came in first, too.

Any magazine which says something negative about your favorite car or doesn't place it in 1st in a comparo is a crappy magazine.

Ok guys

My name is Alex and I represent the shop that hosted the Dyno Day... it was done at Performance Motorsports (New Page 1)

Dyno in question is a Mustang AWD Variable Load Based Dynamometer
Last calibrated the morning of the dyno day. We recalibrate the dyno weekly to make sure everything is within spec since we use it heavily throughout the work week. We are UPRev's #1 Pro Tuner and our in house tuner is constantly on the dyno tuning mostly 350zs and G35s, majority of which are boosted.

The way our dyno differs from a dyno dynamics is the way load is distributed... iirc the dyno dynamics has a set percentage that it applies evenly throughout the RPM band. Ours is a variable load based dyno which simulates road conditions. We plugged in OEM specs of the 370z before dynoing the cars.

The way we dyno is the same way as the pics shown below... with 3 fans blowing up front. The dyno is in a soundproof room with a vacuum for the exhaust fumes. All the participants were setup the same way and given their standard SAE corrected final figures. They all ranged from 304rwhp to the OP's posted rwhp. Even had an 04 G35c w/ a Vortech SC doing 34xrwhp w/ a really messed up tune from another shop.

Basically what I want to point out is that by no means did we "pad" numbers or do any changes to the dyno to get desired results. A couple of the guys did before and after mods dynos and the gains are pretty much in line with what has been seen throughout this forum. I will hope that the rest of the dyno participants can take some time and post their results.

I am not sure why the outputs were high... our shop GTR in stock trim dynoed @ 410awhp iirc... And we are consistently within less than 10-15 whp difference from the closest competitor shop's dyno output (he has an eddy current Dynojet).

It could be the way our dyno is setup where pretty much the car is sealed in a room etc.? or maybe our rollers need servicing? or a million other things.... but bottom line is, like what was mentioned by others before.... A dyno is best used a reference to gains or losses from modifications done to the test vehicle and for tuning purposes. Wanna know how fast a car really is? Go race the other guy or go to the strip and get your trap speed, calculate that with vehicle weight and some other factors that i cant remember of the top of my head, maybe someone can shed light on that formula?

So I'll try in the next dyno day to see how far off these first set of reading are.... also our shop 370z with Greddy TI-C exhaust, Berk Test Pipes, Injen Long Intakes pulled 316rwhp... but it also has only 2xxx miles I believe, how far off is that from the norm?

I just found this thread. It's very um . . . interesting. To the OP, while I share in some of the cynicism expressed by others thus far, I do want to say that I appreciate your sharing of the information you have. The sharing of information, however 'out of profile' that information may be, is not something that should be discouraged, imo.

:iagree:

Agree also. Think it's a case of simply not knowing better, new to the 370Z dyno world and believing what he saw was true. It's how we all learn at times. No harn, no foul.

The internet can be a bit harsh at times as you're not in front of the person and keyboards usually don't hit back. Think we are all guilty at times.
