I admit, I don't fully understand it myself. See this post:

http://forums.rennlist.com/rennforum...re-torque.html

From that discussion:

"at low rpm the pipes are too big to keep gas flow velocity at it's best if the pipe is sized to keep the flow maxed at high rpm."

"Back pressure loads the engine and produces torque. It's all about compromise. Load early and top end hp suffers as the engine labors."

The loss of that torque was what drove me to a VF39. Once I lost it I really wanted it back. It was a noticeable difference, and I felt more turbo lag. I'm glad I did, because off-boost drivability is much better with the VF39 over the TD04.

It also has to do with the air/fuel ratio. An A/F ratio of 10.5 at WOT will yield the maximum amount of toque while something leaner (around 11 up to 11.5) will give you more top end HP. In short, it's all in the tune.

Wanted to throw an update out there. I have been stage 2 for 4,000 miles now and everything has been working out well. No issues so far at all.
**Granted it is practically still new but there have been engine failures on brand new cars.

The car is driven fairly conservatively during the week. It has been through 3 autox events and some spirited driving every now and then.

Also wanted to say thanks to everyone who contributed so far. After reading countless horror storries of engine failures, it is nice to see so many people doing well with the stock block.

It's been a little over 1 year at stage 2 (about 6 months with the EBCS tune) and it's great.

I've been 20k miles on stage 1 and now 5k miles on stage 2 with nameless TBE and a torqued performance tune which on virtual dyno gave me numbers of 295 whp and 310 wtq, which i believe to be about 95% accurate to a real dyno. Feels great, drives like a champ, and no issues whatsoever. Slight boost leak on the stock bpv which is to be expected.

Stage 2 with Invidia catless turboback. Never had it dynoed but the car felt very torquey until about 5k rpms.
Got bored, went K&N typhoon sri, Grimmspeed ebcs, vf39, sti tmic.
Protuned by Harvey at The Boost Creep in Longmont.
Car made 296 whp and 325 wtq. Ran stage 2 for about 15k miles and now 2k on with the vf39

What kind of service?

If an oil change, then no.

You have to be more specific.

hey guys make sure to post your turbo's too just in case

also if you have a built block now running stage 2 please post that you do so no one gets confused between those who have stock blocks still and those who dont.

make another thread for that.

a 20gb would be fine for DD.

HOW LONG: Bought car in October 2012 with 51k, had the DP and CBE but was unmarried and no access port to be found. Subie dealer bought me an access port and flashed Stg 2 OTS map. I suspect the car has been running stage 2 for some time but at least the 12k I have put put on it. Only issue so far has been popping the gasket/coupler between the throttle body and TMIC. Gasket has been removed and coupler refastened. Has been good for a while.
UPDATE: Have been Stage 2 for almost 1 year (16k miles). Now have 68kmiles. Car runs great and hits target boost @ 18.5psi, occasionally hits 19.5 but not often. I have ran into an issue and am not sure if it is Stage 2 related or not but thought I would share. My clutch is slipping at 80%+ throttle while in boost..max boost. I can drive all day long and keep it 15psi or lower and it is fine. ...for now but a new clutch is coming sooner than later. And no...I do not ride the clutch. I also get he occasional grind when up shifting into 3rd but never downshifting into 3rd.

I bought my 2011 wrx new and drove it stock for maybe a month. Got a cobb SRI and flashed stage 1+sf on it, ran that for about 6 months or so. I then installed a catless downpipe and ran an open source tune for about 6 more months. Eventually I switched to the cobb stage 2+sf map which seemed to run a bit smoother in my opinion. Installed a process west top mount intercooler and ran the same stage 2 map for a little while. I was getting some overboost so I went with a grimmspeed up-pipe with the external wastegate, added some colder plugs, 1000cc ID injectors, fuel pump, grimmspeed BCS and a protune. It made 293/310 and it was pretty fun for a daily driver. At about 25,000 miles I started noticing some blue smoke on cold starts and figured it was oil blowby (which it was) and cleaned the intercooler, intercooler pipes, bpv, and some of the throttle body of oil residue. The smoke was gone for a little while but eventually started making it's way back. A/F was getting a bit quirky earlier this year and I knew in my mind that one of the piston rings was letting go.

Sure enough the piston ring was toast in cylinder #4 I believe and basically I went with a whole new motor/turbo setup. I had fun with the car while on the stock motor but didn't really seriously beat on the car too much. I don't know if it was one of the 4 maps that I had used or maybe just mechanical but it definitely should have lasted a bit longer. I had planned on building the motor and looking for more power anyway but it just happened to come sooner than I had hoped. Thousands of dollars later I'm back in the car making a healthy 381whp/389wtq on a blouch 3.0 with a pretty safe tune and loving it.

i hate hearing stories about this. especially since im at about 65k miles now with 35k at stage 2 with similar mods. makes me think that im driving a ticking time bomb

There are always odd ball cases like that. There are also cars running GT35R turbos that last a long time on stock internals. Luck of the draw, and relative to so many variables.

Chance are, even if he hadn't made the modifications, the engine would have blown 10k later. Could have been a bad tune, etc etc, but...

Get a high quality tune if you're going to go to stage 2.

my stage 2 tune is a dyno protune. this is just the kind of stuff that makes me not want to install injectors, uppipe/EWG and fuel pump. ive gone 35k w/o blowing up, and it worries me that if i change anything it can blow up at anytime.

See the interesting thing is... Most of the things that are added are supporting mods which actually make things run better, assuming that quality parts are used. Turbo inlet pipe, injectors, TMIC, CAI... It all really comes down to the tune and how the ECU copes with the change in airflow etc.

Wasn't saying that specifically towards your case :P Generalized statement is that people need to get quality tunes.
