Even then, the MS6 has the same setup with a much smaller loss, a 50hp loss is simply unacceptable. Don't get me wrong I still love the car, but Mazda needs to change it's numbers, the other claim isn't fair to the consumer if this dyno was well done.
Edit:
on a lighter note that means that a CO2 system could bring about rather large gains.

It is not a 50hp loss!! The car wasn't dynoed correctly. With no air going through the IC Core the intake air temps get very high and the ECU pulls timing and boost to prevent detonation, mostly at the top end, reducing power considerably.
Also, who knows if the tricky torque control is holding back power as well.
Besides, the torque numbers look ok down low, 245wtq from 280 rated is a 12.5% loss.

They're just blowing it straight at the front of the car, from what I can see. There has got to be a standard procedure for dynoing TMIC turboed cars beyond blowing air at the front of the car like you would an FMIC or non-turboed car. The MS6's come in low, too, but I always that was AWD drivetrain loss. Now with the MS3 coming in low, I'm wondering what the deal is. The GTi came at 10% below claimed crank output and the MS3 came in at 18% below, same dyno, same day. Something is up with that.

MS6 dynos often show a similar loss. I don't think that after the RX-8 debacle and the new stricter SAE reporting standards that Mazda is fudging the numbers. I think it is poor cooling to the TMIC 'cause it's perpendicular to the airflow from the fan vs. an FMIC getting a direct blast. The MS6/3 are retarding timing due to higher charge temps. If some one can tell me why I'm wrong, I will happily listen.

From this thread over in the ms6 section:

You can see that after 5,500 there is a signifigant drop in power, which is similar to what is shown in the dyno that was done here. Thats a substantial drop imo and thats what worries me the most in terms of its performance, wish it could level off like the GTI does...

Yeah, that has been consistent in almost all the dynos done on this engine. Some say that replacing the stock BOV and doing various other mods helps keep power up after 5500, but others say it's the tiny turbo being maxed out. It really is tiny. You should see the cutaway engine they have at Zoom-Zoom Live. In comparison to a full-sized turbo, it's kind of like Baby Taz on the new WB kids cartoon compared to the full-size Tasmanian Devil on the Bugs Bunny of old.

I don't understand everything about Dynos, turbos and intercoolers, but logic woul ddictate that if the IC isn't gettign the ampount of air that it is supposed to, the power will not be there either.
Cold air = power
Hot air = not as much power

Very interesting to see. In the end the cars potential will be as good as people choose to make it. It is still a very capable car.
With all the info coming in from the Speed 6 there is no real reason to be discouraged by this video unless you plan to drive the car around town with the hood up and no modifications.
Darn Honda sounded way better IMO.
Good video though.

Yeah they definitely need to dyno that with the hood closed.. are they just idiots and didn't realize that all the ductwork in the hood actually does something and affects performance? Now that these numbers are out on the net people are going to be bashing the MS3 like they did the RX-8 dynos ugh.

You have to drive the engine b/f you listen to mag reviewers. The power on my MS6 puts a smile on my face every time I get behind the wheel, as it does for most of the people who have driven it. A fair number of owners on that other forum have come off much more powerful cars such the STi and Evo, and they are happy with it for what it is: a great compromise b/t daily driver & performance car.
Now, do I wish it had a twin scroll? Hell, yeah! But then I wouldn't have gotten it for $24.3 K.
