2012 factory freaks?
 

@phate thanks for the interesting info regarding the 2012's you've worked on.

There seems to be a trend noticed by our PERM magicians that the 2012's are showing amazing numbers in comparisson to previous model years.

Have any of you got VD or logs of cars with similar mileage and mods that we can take a look at to see if Mazda is up to something here?

@Lex

because skyactiv yo.

I just bought a 2012, it is completely stock. I can do a few pulls and see what the logs show. I can report back this weekend.

From what I hear, the skyactiv's run a ridiculously high compression ratio and on 87 octane...apparently they come with a fuel pump that pushes out astronomical psi. I was under the impression that a high compression ratio need premium, but this fuel pump negates that. I may be in way over my head, but please let me know if this is something we can look into?

I was definitely kidding, but am interested to see if anyone finds some differences like the piston heads from 2010/2011

Thanks for posting. I'll have a look through my files for older model years results.

Wait your talking about sky active not mazdaspeed 3 making awesome hp?
I drive a 2012

Topic derailed a little there. Definitley talking about the Speeds (not sure if some form of Skyactiv technology is being implemented in 2012's though).

No man! This is a Mazdaspeed forum not SkyActiv. He is saying that 2012 Speeds are pushing higher numbers with the same setup as previous years.

Please go away.

Because 2012

Hehe I remember you always hating me lol

Girl cruze runs on 87 and i dont no how it does it. 30 in the city 38 on highway

Give them a chance to get a few miles on the cars. We already know there are improvements from gen1 to gen2 (pistons, ECU/tune etc) but generally as valve deposits accumulate, the turbos get some wear, etc. things start to level out power wise.

The gen1s and ms6s also had a nasty habit of losing compression over time. Whether it was carbon deposits on the rings seizing them or worn cylinder walls due to fuel spray - hard to say. The piston upgrade for the 2010+ cars I think addressed some of these issues.

Do any of you gen2-ers with higher mileage cars test compression? (http://www.mazdaspeedforums.org/foru...95/index8.html)

I thought the DISI motor has been thr same since the first speeds in 06 (or 07, brain forgets numbers) and skyactive is only available on 2012 mazda 3 in the 2 liter motor...
Probably wrong tho

i have a 2010, my neighbor has an 11, and our friend has a 12. Of the 3 of us with generally the same mods (in sig) the 2012 holds noticeably more boost than our 11/12. Now the 11 and i are able to run more timing (all tuned by same guy) so this may explain the 12 not being able to get away from us in a race, but then again it may just be his car / driver mod at that point.

This thread fails so fucking hard.

Because Pu? lol

I cant groan you cuz I'm on mobile, but screw you man.

GenPu 4tw?

@Lex, we'll see how my 2012 ages. I had a previous DI car (08 GTI) that never showed any signs of "aging" after 27.5k miles. But apples to oranges in that case...

Wrong.

The late production 2011s/ some 2012s seem to hold more boost with lower WGDC. I think they may have modified/ changed producers for the Wastegate setup during this timeframe.

@ms3_150 this may explain Jeffs badass boost haha

Def. interested in this more.

In before engine swap of wife's Skyactiv into my Pu for awesome MPG's and pretty blue engine cover (all i got for an engine cover was this ugly silver metal thing). I have logs of 2012 Pu if needed.

Well track season isn't too far away and that should help us learn a bit more. This will be the first time we get some 2012s out there right?

Has anyone considered that maybe Cobb, not Mazda, is changing things? :naughty:

I already went out once, OEM down to the tires aside from my Intake/internals/tune... 14.0 @ 108 (well, 107.83 but who doesn't round that shit up?). This is at PIR, which is completely unprepped, so it pretty much blows.

We're talking about genpus??

well... fuck.

hmm i actually remember a thread talking about an improvement on the shape of the cylinder head...

I'm gonna call mazda motorsports, then. Those lazy fucks don't open til like 10am western time.

Edit: The piston design changed in the second gen's, of that I'm sure. Hadn't heard anything about the head, though.

i just got my 2012 speed 3 and im subed into this thread wondering what the outcome is

Holy Beach Balls Aquaman It's Tapatalk

interesting....

oh i mean piston... lol

Jesus! did you land a 2.6+ 60ft??

This thread is a cluster fuck. Half of you know what you're saying and the other half doesn't even know what the topic is.

I've discussed this discovery with @Bucker before and I think we ended at a new style of wastegate or possibly even boost control as the reason. A change in piston head design wouldn't alter how the turbo holds boost.

Edit: another viable option (and this one actually makes the most sense to me in retrospect), would be that the exhaust side on the turbo for those production years is a bit larger.

2.49, not a whole lot better lol

dont think anyone would believe; but look at my sig for pow'a #'s. Completely stock numbers

I'm not surprised... Mine where always like 270-280 on straight pump with intake & tune.

fuckin 2012's. Although I have tuned a 2011 and 2012 with my same mods, and they both need more wastegate to hit the same boost as me. Of course i have a grim speed, but it is in 2 port.

3rd gear wgdc goes from 40-30-80
4th gear 30-30-30-60
5th- 20-20-20-40

If it was different boost control than that would explain a difference with the oem tune, but once you do a custom tune, and you see higher numbers with the same mods than it is either because the car is newer, or there is something mechanically different.

Of all the cars I've owned I've never had one make more power than the others like it. Sure maybe a 3-5hp variance from the "norm", but nothing like this, whether the motor had 1k or 50k on it... I'm inclined to believe the difference is something mechanical. But I'm not inclined to take my motor apart to find out what, so I guess we'll know when a 2012 spits out it's guts... heh

True, plus the likelihood of getting a 'ringer' as they call it nowadays is even less, what with all the precision robotics and quality assurance programs modern cars go through.

Manufacturers change parts and suppliers all the time. With a modern car having around 15,000 parts, there are bound to be significant changes even mid-year.
