My 2007 Mazdaspeed3 dyno!

People who call a dyno bull have no intelligence, chassis dynos are not devices used to give you the exact power your car make.. its only good for comparison/tuning purposes. Dyno a stock WRX on that same dyno, gives you a good comparsion, who the hack cares about the power figures. dyno it before and after you mod it. again that is good...

Now from the dyno, all I can say is that cooling for the TMIC is an issue when dynoing, as well as octane. And also it has turbo lag and power drops dramatically after 5500rpm!... that is wat the graph is telling you!.

And the STi has a better AWD system, tires, suspension, center of gravity, and its LIGHTER than the speed6... OF course it runs circles around the speed6.. omg..

Go to an engine dyno if you want exact power figures....... these dyno threads are full of useless discussion, the poster just showed you his graph, thats what he made, its not BULL, coz he didnt MAKE the graph up... now at least this graph could be telling us Mazda OVERRATED the car, you want them to UNDERRATE IT?!

Now this is a little more like it. Bonestock. 94 octane. around 600miles on the odo. 259.9 whp and 247wtq !! woohoo!:)

Come on, you've got the HKS BOV. How does the correction factor figure in? Does it need to be applied to the figures you got or do the figures already factor it in?

people can call BS all they want. Those are the numbers it put down. It was a cold day we had the high powered fan right over the TMIC like it should be. Don't believe me? Who cares. Thats what it was and thats it. The dyno is a Dynocom. It reads very similar to a Dynojet. The numbers that it reads are accurate, a bunch of local tuners have used this particular dyno and are seeing the same results as they are on a dynojet or dynapack.
heres a link to their website

I have no doubt that this car is capable of putting out these numbers, and you had the absolute perfect conditions. Lets try and look at this as a whole. Here is another dyno, that is more objective, and seeks to achieve a realistic amount of power. It's not done personally. Then compare it to the dyno you got. Take it or leave it, and make your own opinion. If you take everything as the truth, this means your Speed 3 will absolutely trounce the Magazine's Speed 3. They are like two totally different cars regarding HP.

The fact is, when you purchase a Speed 3 or Speed 6, it's a flip of the coin, and this car has tuning issues to the point where climate is playing too big of a role on how this car performs. You may get a fast one, or you may get a severly underpowered one. Perhaps, if you take a 259whp dyno done personally, and combine it with a 215whp dyno from a credible magazine, what you are looking is about a 230-235whp dyno average. I won't call BS, but I will call that a VERY generous dynograph. The torque seems to be even across almost all dynos. Why the huge dicrepency between HP, and not torque on various dynos?

Personally, I find my Speed 6 to be very finicky. Some days it's noticably faster then others. I never had that inconsistency with my STI, as the car was FASt all the time, which tells me Mazda still has a ton of work to do to get this engine running right. Def a work in progess IMO. I only wish my Speed 6 had even 240whp. I'm sure many Speed 3 or Speed 6 owner wishes that as well. With those numbers you put out, assuming they are accurate, you should be able to run your Speed 3 at the track in those climates and run 13s without a problem. Your Speed 3 will also be able to take out the EVO or STI, so congrats. :)

Automobile magazine is 'credible'? I read the magazine that had the review of the Mazdaspeed3...and the GTI....and the Si.... Automobile magazine had NOTHING but praise for everything.....no downsides at all.

LMAO!

And yeah, they totally screwed up the intercooler cooling....if the MS3 relies on ducting and ram-air to properly ventilate the intercooler, then you have to SIMULATE real world conditions by simulating the ram-air and ducting effect.

So tell me. What do you think is a good average of what the Speed 6 and Speed 3 will dyno at. Is it 250+whp? Can the Mazdaspeed 6 run 13s all day like it's supposed to, assuming it delivers 240+whp on most vehicles? If we wanna believe that these cars put out 240+whp on average, we need to see some consistent track results. Believe me, I'd love nothing more then to have a 240-250whp Speed 6, and if I could go to Mazda right now, and know I'd get a Speed 3 that will have more WHP and torque then my STI (dyno's at 240whp on average), and also be lighter, which means it would be faster, I'd be right at the dealership handing in this Speed 6 for one.
I'm just trying to get some objective impartial information here, so if anyone can throw in some good information without partiality and bias towards Mazda, I'm all ears. Thanks!! :)

yeah, but they dynoed with the hood open .. hood open TMIC FTL

Yeah I was quite disappointed with the results but I hope Mazdaspeed will come up with a chip to correct those issues they address from Automobilemag since I already ordered the car.

BTW what does TMIC FTL mean.

I have no idea what a good dyno would be, I'm just saying that 'Automobile Magazine' is a very fluffy publication.

Obviously, I hope for the more optimistic numbers, since I've preordered one already. Either way though, the reliability will PROBABLY be better than the VW GTI and the practicality is MUCH better than the Civic Si (I'm a travel RN who needs the cargo capacity).

they sure do have pretty pictures though :D

Ain't that the truth. I subscribe to Motortrend and Automobile and while Motortrend is the more entertaining magazine to read (I love their writing style), Automobile magazine is just so well put together and their writing can be pretty funny also. Their photography is just a step above motortrends though. I would love to be an automotive journalist for either magazine. It sounds like a job that I would love!
 
I don't think I'll renew automobile.. I get motor trend, road & track, car and driver, automobile, and autoweek (thanks mazda.. they give me a free 1-year subscription every time I go to any event lol). I think I may just get a subscription to Top Gear mag.. it totally pwns the pics of automobile, and includes elusive little euro cars that we sadly don't get here :)

I do like car & Driver and Road and Track also, but I don't like their writing as much as Automobile and MT so I just read those for free at Barnes and Noble. I'd like to get a subscription to CAR magazine. I like them a lot and I like the write ups on "not available in the U.S" euro cars too. G'mon Ford, Give us the Focus ST PLEASE!!!!

Thank you! (first) You just proved alot about the cooling issues in the magazine dyno had. Well done!

The TMIC cooling issue was a major detriment to the validity of the Automobilemag dyno.

hey guys, new to mazda forums but not new to horsepower and tuning....i just bought my ms3 yesterday and with 150 miles on it i can definately tell you this thing is fast...faster than both ms6 i drove. i would say 235-245 whp is definately inline with these cars.....i will dyno my car soon on a dynojet and get my numbers back to you......all i can say is mazda has a winner in the ms3
