How does Nissan get away with publishing those HP and TQ numbers for the Z?

My whole point was that the crank hp is under-rated. Read my whole post vs. selectively reading what you want to read.

The stock Z is what, a high 13 second car at best, to low 14s?
Many cars on the road nowadays are capable of doing that stock as well.
I love the Z but its not that fast of a car.

Mazda RX-8s are slow? Sure in a straight it wont hang with a Z. Top Gear testeed the Rx-8 and 350Z on their course and guess what? Same exact time which means the rx-8 corners a lot faster than a Z.
I also heard this from a RX-8 dealer, they engine was running too hot and burnt out the cats so they detuned the engine and added more gas to cool off the engine. This is also a partial reason for why it gets sh*tty gas mileage. That and it has 4 ignition sequence per revolution. Don't know about the the 12 hp (250 claimed at release, readjusted to 238) difference from being detuned from Mazda but a chip will yield some good gains.
On the flip side, some manufacturers do rate their engines lower than what it actually produces. I don't think they lied or embelished the 350z's. The dynos show this.

+Suburu underated the WRX as well. One of the turbo magazines or sport compact back issues did a dyno test on a stock WRX and stated it was underrated as to create a larger gap between the base vs the STi for marketing purposes. + 10 hp higher than it should be stock
+Hondata finds more power on the Honda K series motors by upping the redline on a bone stock motor. Honda seemed to have lowered the redline on those newer motors to meet their requirements. An intentional detune/underrate.

I'll call BS on that guys post just the same. You're going to go with some jokers dyno numbers over what the manufacturer claims? First of all, it's the internet, and second of all it's a DYNO!! You really think he's making more at the wheels than his car is even supposed to have at the crank?? That's a MIGHTY big under-rating. Think about it. 205hp at the wheels... let's say 15% drivetrain loss... thats edit:240hp at the crank.... from a 4 bangin 2 liter...
Uh huh.... I'll have some of what you're smoking.

you guys want to see underrated?? How about the ford GT?? its marketed with 550hp, but on the dyno it puts out 535hp (2.7% loss). fords magical engineering.....I dont think so. Its putting out over 600hp at the flywheel, but still cant spank a C6 zo6!!
^numbers are from dec 05 motortrend.

You guys crack me up. You think this would be the first time in history that manufacturers claimed less power for a particular car? Maybe Honda did it to not overshadow their "premium" Acura. Others have been well documented cases, such as Ford, Chevy, and Dodge in the 60s and 70s lowering output numbers for insurance purposes. Ever stop to think that maybe.....just maybe, that Honda was trying to keep their published number below that magical 200hp for a reason?

also you are talking about dyno numbers... dyno numbers don't mean ****, as its been discussed you can go to one dyno and put down 240whp go across town to a different dyno and put down 260whp...
Its amazing how much emotional energy people put into numbers, Run what you brung, its not all about what numbers your laying down on the rollers its how well the chasis, and you as the driver uses the power.

that's so true. i've noticed that BMW also under rate claimed stock hp.
