wow is that A/F curve safe? it runs really lean from what i can tell up to about 4200rpm and then tapers to 11.3 i guess because dyno sheet says thats the min a/f ratio.

I thought it was high also, they said it was on the high side, but not much more then they usually get for the 09's.

Safe? Not sure i'd say it's safe or not, it's how it came from subaru. I'd hope they wouldn't release a car that is going to grenade when kept stock. Atleast it does drop to the more 'safe' levels in the higher rpms.

End of summer I'm expecting to do a few things (including tune) to it. We'll see how she does then.

Holy crap that's a good running car. My 09 made 259 stage 2 protuned but on a mustang dyno. These 09's sure do run
These cars seem to wake up a bit after 5k miles also. Most dynos I've seen of 09 including mine were with close to 1000 miles lol .

....with those numbers (if they are accurate) on a mustang dyno, that will put you in the low 13's high-mid 12's with a good driver. I didn't know they had that much power from the factory.... Torque seems right...a little on the high side...but the horsepower.....

Oh I'm not complaining. I'm just tossing my opinion out there.

Here ya go. Surgeline tuning. Stock 2009 wrx. 92 octane. I doubt this one really makes over 30whp more.

Here's a 2009 STI on their dyno.

that sti does not look healthy. must have had a few knock events on the way to redline with the way the power looks like its "pulled" in several rpm regions (3800, 4600, 5400, etc).

to OP, dude enjoy it that motor looks like it loves to make power so mod tastefully

That other 09' wrx dyno was pulled on 06/08/09... That had have been practically fresh off the line and next to no miles on it. I could see that having some affect.
EDIT: sorry, totally mis-read that, I thought it said 2008 the pull was done, my bad.

Surgeline said mine was 'high but beleivable'. It's more then I expected, but the car does pull pretty hard (butt dyno). They also said they usually get 250-255whp with the 09's. So I do'nt know what's up with the other dyno posted.

In anycase, I plan to get a couple time slips with it in a few months when the weather clears up. I'm curious what I can get out of it. I'm an ok driver, but haven't ran an awd car on the track yet.

Just thought I'd share and I do want comments and questions, positive or negative.

You may or may not have a factory freak. If you do, be careful with that motor. They have been known to blow pretty quickly STOCK! Perhaps they were "over-tuned" straight out of the factory. There are a few articles out there that indicate the stock 09' WRX is almost as quick, if not quicker than the 09' STI.

Yeah, there is a good chance my motor will get broke, but it's because it's built right in the middle of the 'bad' batch

So.. hopefully it doesn't fail like most of the rest from those couples months of build dates, if so, I just hope the new motor will make close to the same power.. lol.

Yep, spun bearings and broken ringlands. Not sure if anyone has tried this yet. If you're up to it, perhaps change your oil to a viscosity of 10w 30-50 as an experiment. You might loose a smidge of MPG....just throwing it out there.

Breezio, try to drive conservatively. I really thought subaru fixed at least the AFR problem in their cars.

In 2007, they started running a fuel curve just as shown in your graph. 14.0 @ peak torque = death. I wish I lived closer, I'd flash you for free, just to be sure you were not another statistic.

@ 14.0, through 4000RPM WOT, there will be knocking, and on 91 octane especially your motor is doomed. I understand now at least one of the reasons the 09 bearings chit out quick. Knock at full load causes massive stress on them.

I've been through many ordeals, some have been with SOA. If your car is stock, and your motor blows, they will do everything in their power not to warrenty it.

The fact of the matter is, you will most likely win the battle for a covered motor. But I bet the process takes much of your time, not to mention from broken to fixed will be ~ 2 months.



On another note, I wish I could get my hands on one of these 09's. I think they have tons of potential (probably high 11's on the stock turbo). 263 out of the box is a bit much, as on factory calibrated mustang dyno's a stage 2 sti will put 260-265 out, but they are powerful out of the box nonetheless.

Well... according to the thread about the 09' bearing problems, SOA has been good at replacing the motors and getting it done within a few weeks, and it's on a specific build date of cars, thus the problem (with the bearing failures atleast) being bearings/crank themselves and not the fuel map.
That's what I'm reading and hearing atleast.
I could see the factory map certainly causing problems if you get a bad batch of fuel or something.

I've been purposefully driving it on the hard side to see if the bearings are going to crap out.. lol.

I suppose we'll see if/when it happens.

I can't imagine SOA winning the fight if the motor blows up under warrenty because of their fuel map, but I haven't dealt with them yet. First subie I had was an 06' Legacy, never had a problem with it.

On the oil comment. You meaning to run the thicker stuff to save the bearings or to make them crap out faster?
I'm currently running Mobile1 5w30.

im confused. Surgeline said that thats what there seeing on 09's and its not out of the question? they see no problem with bone stock cars making the same HP to the wheels as the motor makes to the crank????? people at surgeline are sniffing something! not to mention it takes one person one click of the mouse to make a dyno total number read whatever they want!! funny how all other dyno's (mustangs, dynojet ect), magazines, guys posting on forums, you name it!! bone stock are putting down 220-230hp. i highly highly doubt thats the real number. but hey total number doesnt matter. it matters what you do at the strip and what ever you add on go back and see the increase in power.

P.S. bone stock 09's are running 13.3qt miles. if you really do have 263hp then i need to see 13.0 at least!

If you don't want spun rod bearings I'd switch over to a different oil IMMEDIATELY. Mobile1 does not agree with these motors. There are a ton of threads about it if you search. Just FYI but it sounds like even if your motor does go your build date guarantees you'd probably get a new motor lol

Not 100% sure about this. I see the threads, and hear the gossip about motor failures and mobil 1.

But I ran mobil 1 in an 04 STi for 65k, and in an 07 STi for 60k. However, I have to agree about the oil literally having the viscosity of water. This is a characteristic that tends not to agree with some of our motors.

Are these the non-corrected numbers? If so do you happen to have the corrected numbers? They should be slightly lower.
FYI, my 2010 with 1005 miles dynoed at:
236.2 HP & 243.0 TQ
With correction that came to:
227.4 HP & 234.1 TQ
