My 2007 Mazdaspeed3 dyno!

cmon guys stop the hating.
We all (most of us anyways) want to be optimistic about the number on the ms3. The numbers that came frm the magazine were a real downer; sand to tell you the truth that the magazine was so irresponsible in publishing numbers that are not accurate. It is obvious to everybody (even me, i know nothing about tuning) that the dyno was not correct due to the inability to cool the TMIC properly. I would disregard that dyno on the spot; not even consider it for a base.
Now having an actual owner do his own dyno with a proper cooling method that is something i can take at least as a base or comparison point. Not all dynos will come with the same numbers but they should not fluctuate that much.
For now congratulate the owner with a really fast ms3 and wait to see more people bring in their dynos.

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

I'm jealous of you. Fast truck and a fast hatch. Congrats!

IDK I want to believe but have you seen the dyno from automobilemag, it wasn't nearly as good.

Well their dyno for the GTI was pretty low if you've seen what most people are getting on the GTI forums (golfmkv and vwvortex).

I think that automobile's dyno was bad.
 
The posted dyno results are absolute nonsense. Why???

A dyno measures torque and the torque curve is completely wrong. Mazda quotes peak torque @ 3000 RPM. On the posted dyno graph, the torque is very low at 3000. In fact, it is much, much lower than the Automobile dyno, which correctly has the peak torque at ~3000 RPM's.

Numbers may change with different cars, dynos, temperatures, etc. but the shape of the torque curve should be fairly constant. Sorry folks, this one isn't even close.
 
For all of the 'nay sayers' out there:

Prove him wrong. None of you have provided proof that his dyno is not correct. I am skeptical of the results, but I have no way to prove him wrong because I DO NOT OWN HIS CAR! And neither do any of you.

I don't care what a dyno says about my car because it is real world performance that matters in the end.

That is just my $.02
 
I trust dynos to show me if something is wrong with the car in terms of the ignition/fuel systems, but not much more than that. There are so many variables involved.
 
i like this he has a dyno sheet and all these cry babies call bs seems most of you just cant handle driving a lower hp car...lol if hes wrong get on the same dyno he ran on maybe you will get a higher number also! you think of that? no! your to busy like a bunch of 2yr olds calling bs, get on that same dyno and see what happens...maybe there dyno isnt calibrated right i wasnt there to see nor were any of you i assume!

good job is what i say! now what really matters is can you handle all the hp and tq? later man have fun
 
hope this isn't BS. awaiting other dynos such as from got_titan to come to any conclusions.

Yeah I saw dyno numbers but it was no where near these numbers.
what im saying isnt just the numbers the calibration on the dyno might be wrong it could be right. who knows the only way to really find out is another dyno... hes not lying hes got the paper... cant call him the idiot(you wernt) i would of posted this too. if someone in that area knows what hp there at get on that dyno and see if its right

I did prove him wrong.

The torque curve is simply wrong for that motor. What is so freaking hard to understand about that?
 
If you take the hp curve and switch it with the torque curve the numbers would be very similar to the autoweek dyno.
 
Good point I don't think anyone has quite figured that out yet.

Has the original poster even come back? Something was probably up with the dyno he went to.
 
I can't read the numbers but torque is 280 while hp is 263, so it wouldn't make sense that the hp was the larger curve, in fact the numbers would be almost spot on if you change the curves. I highly doubt the whp is 259 for a stock ms3.

You haven't proved anything but I believe that you are correct after further inspection of the dyno charts. It looks like they are reversed - at the bare minimum.

Maybe this guy was 'experimenting' with photoshop:)

+1. There's no way a stock MS3 would somehow magically shift the torque peak from 3000 rpms to over 5500 rpms. He's playing with a boost controller or something. Notice he hasn't confirmed that he's got an aftermarket BOV although the posted about it on the Mazda Canada forum. There's more to the "bonestock" story than he's letting on.
 
This thread is getting lame already. I have quit caring if his dyno is real or not. Obviously some of you care too much about whether it is real or not. Who cares, I'm done with this topic.

Hope you all sort it out eventually.
 
why not take it to the track and lay down some #'s....that will tell us pretty much where the car is at...also congrats on the new car...they are really nice!
 
The dynos don't mean S__T to me. This car rocks regardless of what the critics and naysayers say, and I don't need a dyno to tell me that. I have barely even broken mine in yet and already it shows a ton of potential. I can hardly wait until I can redline it just to see what it has. Although the initial bite is not quite the same as the MS6 (that is to be expected with the MS3 only being FWD), power comes on quickly and savagely. Although less visceral, the acceleration of the MS3 easily trumps that of my newly-departed MSP which was not particularly slow. My biggest concern is whether it will be as agile as my MSP. I'll have to wait until next Auto-X season to find out.
