My Trailblazer SS AWD has apprx. a 25% Drivetrain loss.
395 HP Rating....Dynoed at 297WHP.
Apprx. 25%.
Just sayin'.

Many large vehicles lose that much. A stock Ram Hemi loses over fifty horses by the time it gets to the drive wheels.

I just got my first cute girl to scream in the back seat the other day doing just that. I don't need a dyno to tell me the car is doing what its supposed to.
HAHAHAHAHAHA!
To the OP: I would imagine a group like the ASME would have a standard for HP ratings on combustion engines. ASME and other similar ratings are usually conservative, I work with them every day. I would assume mazda would rate their engines to an ASME or similar standard as well. This way they can avoid stupid lawsuits like the one you proposed. All they have to do is prove the engine was rated to a standard test, and as long as they followed the procedure they are off the hook, and you will be paying their lawyers fees for years after I have paid off my college loans.
Besides the limiter in 1st and 2nd gear, the reason you never see the full 263 HP at the wheels was explained to all of us in high school physics class. See if you have your old text book lying around, pick it up and do some reading.
Not trying to be harsh, but nothing is ideal.

Someone should sue every manufacturer ever who claimed a top speed in a car.
Mazda claims 155mph top speed on the speed3. No road in the U.S. had a top speed higher than 80mph. So they should have only advertised that top speed correct?
Give me a break. We don't live in a country that mandates speeds or horsepower figures (so far). There are limits but it is our choice to suffer the consequences of going over them. Be lucky we don't live in England where they are actually trying out GPS enabled speed limiters..
Go spill some hot coffee on yourself in a drive-thru or slip on a wet floor if you want to make a quick buck the good ol' American way.

did you not know about this limited boost/torque in 1st and 2nd gear? it is very well advertised/documented... i knew about this before i bought the car. didn't really care...
with all of the stupid lawsuits being thrown into our courts, and you would like to add this?
don't expect me to sign up for any 'class action' crap... that's for sure. i applaud mazda for trumping all of the other FWD platforms (at least all of the ones i tried out) and delivering a real 'bang for the buck' ride.

Not true, just disables traction control. Its still limited boost but even that is enough to smoke up the wheels without the traction control.

no car has the power output they say they do. people buy brand new STI's an go to the dyno an put down 223hp all the time. i cant believe someone would actually make a thread like this... (headshake
Also that would only work in this case if Mazda advertised the 263hp, but it was found out it was only achievable at 9,000rpm and the motors had a limiter at 6,000.

Perhaps I'm not being clear, and I think I'm not. I should not have put the slash there, as people might think that I'm making an EQUATION for HP as Torque DIVIDED by Time, which I'm not. Revolutions per MINUTE and the 5252 constant (from the old 33,000 ft-lbf/minute a draught horse is supposed to be able to do) are time measures, thus the Torque applied OVER A PERIOD of time statement I'm actually making.
Dyno CALCULATE horsepower because, you can easily measure directly the linear motion of one horse but, it's pretty hard to directly measure the rotary motion of an internal combustion engine. Torque and RPM are easily measured directly and these form the basis of the horsepower calculation.
An example is a water brake dyno. The more torque is applied to the unit, the more water is needed, until it maxes that value at the torque peak. More water braking is NOT needed at the horsepower peak. Thus the dyno does not respond to HP at all. They used to call dynos "torque meters" for a reason.

I agree. My daily driver is a 2007 WRX. Fun little car, but no comparison to the MS3 as far as power and torque. Both cars are bone stock, and my MS3 pulls so much harder than my WRX.

Mazda isn't lying when they say MAX power is 263 at 5,500 rpms. They don't mention a gear, because it's irrelevant. The max crank HP according to Mazda is 263, that's the most power the engine can possibly put out. That's what "MAX" means, lol. Thanks for the laugh. Now that will be 500 dollars because lawyers round UP to the nearest hour. Have a nice day.

What? Advertisements not telling the truth. Tell me it isn't so!!!
Can care less about the Hp rating. I go by butt dyno, and it tells me that this car makes more than enough power to make my drive entertaining, and when in the mood, surprise folks who think they have fast cars. It also allows me to scare the hell out of my passengers just flooring it in "boost limited" second gear.
