Ok well I dunno about all of you guys but I seriously think of persuing something with Mazda. I think their claim of 140 Hp for our MP3 is bogus. I very highly doubt their is anything magical about any advanced ignition timming or anything. Mazda clearly overated their engines and I think something should be done for this.

Isn't this a form of false advertising... or a breach of contract as I was sold and bought a 140 crank HP car. Now I have just seen the dyno sheets of a P5 with intake and axle back muffler.

Look at those numbers.... 17% tranny loss maybe on the P5... but what the heck is wrong with the MP3. We should be stock form about 116 Whp.. give or take... I had mine dynoed, stock intake and 94 octane gas ( always put that in from day 1) with only 106 Whp... wtf is that... with an intake I gained to 101. something... even then, I am at way more then 17% tranny loss.... I am talking about 25% tranny loss on stock set up... come on... this is insane...

130 Hp with 17% loss should be at around 107.9 I have seen 90% of them being at 103 Whp... missing 5+ Hp... here we are killing ourselves trying to gain 5 or 6 HP here and there with $500 mods... the entire time Mazda is robing us of that 10 or more HP's that we bought.

I have a dyno of my car... I dunno about the rest of you... I will not inflate or exagerate the numbers here what so ever... I am just in a really pissy mood today regarding this. No I didnt' lose to any body today nor yesterday... but I hate being lied to... and I think Mazda has pulled a blind fold over our eyes with these handling numbers rather then truly telling us the truth about the real HP numbers. The dyno from one of the Turbo shops had 98 Whp... like huh.. ok... wtf is going on here.

I really doubt that the new Mazdaspeed will have anything close to 170 crank Hp.... in reality we should be using 25% tranny loss in our figures.... ff that is the case... Mazda has probably invented the new standard in tranny lose #'s.... 170 Hp - 25% loss.... 127.5 Whp.... wow.. that's just amazing numbers for an intercooled turbo set up..... :rolleyes: But if you compare to my 106 Whp that isn't too bad at all... :mad:

I just have to rant..... gggrrrr !!1

Thanks

You GAINED to 101? That seems like a 5whp loss to me. Maybe you meant that you gained 5whp with intake?

Okay, so here we go...
Firstly, we have a heavier wheel/rim combo than a P5. That's 1whp right there.

Secondly, comparing YOUR dyno to someone else's car on a DIFFERENT dyno can be like day or night. You'd have to compare on the same dyno to be sure.

Thirdly, despite my 2nd point, MP3's CONSISTENTLY dyno around 110-114WHP STOCK. And P5's CONSISTENTLY pull 101-106 stock. He had 106HP stock (if i recall correctly) so that puts him in the higher end of P5 dynos.

Not to get TOO mathematical, lets say that your dyno is 4HP under (it IS a canadian dyno, is it not? LOL) and HIS dyno is 2HP TOO HIGH. So if you have 106, then you should have 110 (normal), and he should have 104 (normal). That right there shows a 6WHP difference. But theres more factors than that. If you went to HIS dyno and got it done, and you had 2HP more than him, I'd understand your point...but until you do...

Anyway, it's obvious that the mp3 has at least SOME more power than a p5. Again, they consistently dyno about 8WHP more, and their 1/4 mile times, and 0-60 times reflect more power. Case closed.
 
Sorry the gains where at 110.. I made the mistake...

Why is it that my car was the only one that was off from factory specs out of 4 different cars. 4 other different cars hit the 17% tranny loss and some one even at 15%. I was 25%... My friends stock Focus hit my stock reading. He only has 130 Hp at the fly 10 less then me.. and I lose 10 more Hp through the tranny... give me a break...

From factory I am 10-8 Hp away... why is that. I can understand maybe if I was even close to it... 4-5 off... but double that is insane.. I mean we are supposed to have the same #'s and for some reason I am way lower.

I have seen 2 dyno graphs from the same dyno on P5's the highest was 104.1 as best as I can recollect and with intake well they where at 106-107 Whp. As the guy had them all on his computer. Therefore for a P5 to be as fast as mine all you need is a $35 K&N filter. If I only knew before I would of saved a few grand to get a P5 instead...

To make it seem a little fair, Grassroots Motorsports dynoed an MP3 and got 20% drive train loss. It is going to be a little different in each car, but 17% to 20% also makes the difference.

I have not dynoed my car yet, but plan on doing so sometime in the near future. I've been debating on getting one of those home dyno things so that I can do numerous runs with out having to pay out the big money for dyno time. And a home dyno costs less and is more accurate than a G-Tech...

As it stands, you can also do a number of acceleration tests on a flat road from 20 mph to 40 mph and see what your times are. Do so again when you make mods, you will see a difference in the times for sure. Provided the parts make any more power.
 
you were at 106 with the stock intake
then
DROPPED to 101 with an "intake" ?...something is wrong here, did i read that wrong?....
 
I know its a little different, but my dad owns a motorcycle shop, and he has a chassis dyno. He was telling me a while ago that they ran two different Yamaha R1s on the dyno, both new, one after another, and they got a 3 or 4 hp difference. Both bikes were completely stock and they ran them both mulitple times. What im getting at is that the numbers for one MP3 are not necissarily infalibly correct for another MP3, not just because the dyno can fluctuate, but because different cars get different HP numbers from the factory for some reason or another. It seems that it would be even more feasable in the situation of the mp3 becuase a small outside company was called upon to "tune" the engine, their products may not be as uniform as a large company like mazda.
 
look at the bright side. at least we are not the like foci. on focaljet, there have been stock foci that have dyned anywhere from 95 to 110 at the wheels.
 
i dont own a protege mp3, but do they recomend that you put 94 octane? that seams real high for a car like the protege. shouldn't it be like octane 87 or something? well it has been proven that you lose horsepower when dynoed when you use octane your not supposed to use.
 
As for octane, I don't run anything less than 93. Comes from my BMw days, and now it's just a habit. I run 94 when I go to AutoX most of the time.
As for the HP thing, if I'm not getting 140, I'm not too worried about it. I bought the car for its looks and handling ability. Once I saw the numbers, I knew power was never going to be something to look forward to in the car. At least we aren't driving one of the multi-million neons or honduhs on the road. I guess I'm just saying be happy you aren't them and you dared to be different.
 
I have mixed feelings about the 140hp... I was following a late 90's basic ford escort (automatic) getting on the freeway the other day. Started passing him while in 2nd to 6,000rpm, then 3rd we were pretty even until about 5,500rpm, then had to slow down. That's pretty sad in performance(I did have 3 people in the car- he had 1). But then I parked and looked back and think the appearance makes up for it, plus the steering doesn't have pancake syrup in it, like the escort.

It's easy to get angry with the car, but impossible to say mad at her.

hey, those 91-96 escort's are freakin fast man the 5-speed manual are, i don't know about the automatic's though, but yeah they share the same engine as the 93-96 ford probe's, 90-98 mazda miata's, and the 90-94 Protege's. all 4 of the motor's come with 1.8L DOHC 16-VALVE MPFI 125-127HP motors but they are light as heck.
