Default Chris's '11 Wingless STI Sedan Stg 2+ E85 (349whp/417wtq) Goodspeed Performance Labs

So, I've been meaning to post my Member Journal here from iwsti for a while. I'm just now getting around to it because I think I'm about to get booted from their forum. Moderator issue. Anyway, here it is. Enjoy.

Ok, so I finally decided to get all my images and receipts together and start a journal. This is my first Subaru, first AWD, first new car, first sports car... well, you get the picture.

I bought my STI back in November of 2011. I wasn't even planning on buying a car. I was just visiting a friend that worked at Camelback Volkswagen, Mazda, Subaru in Phoenix. We were just supposed to go have lunch and catch up when I walked past this...



Two days later I was driving away in my '11 SWP STI sedan. I wasn't even going to buy a car. Hell, I wasn't even in the market. I had an '01 Suburban and I was fine with it... until my buddy talked me into taking this "white car" for a test drive.

As you can imagine, I got the mod-bug within 1,500 miles. I broke her in gently... ok, no I didn't. I never took her over 6K rpm, even though the manual says 4K.

Anyhow, before I get started with the mod list, I'd like to thank Goodspeed Performance Labs for all the work and sound advice they've given me, as well as Clark Turner of Clark Turner Tuning for my stage 1, 2+ & E85 tunes. Car runs so good, never a single issue. Thanks guys.

Ok, car was obviously stock with the exception of the following dealer installed options:

SPT Short Throw Shifter
SPT Rear Carbon Fiber Trunk Panel
Auto-Dimming Rearview Mirror
Footwell Illumination Kit - Red
(This could be stock, so I may be wrong here)

Here's the journal through each stage...

11/28/11: First oil change / alignment (car was pulling right) @ 1957 miles
11/30/11: Stage 1 @ approx. 2000 miles

Cobb AP
Cosworth CAI
SPT CBE
SPT Carbon B-Pillar Panels
SPT Front Lip Spoiler
Protune by Clark Turner (91 Octane)
273whp / 333wtq




Difference was immediately noticeable. Soooo much fun. However, I was getting revved on at every stop light by every POS Honda on the road. So I decided it was time to lose the spoiler. Also, the power bug was beginning to creep up on me again.

At this point I was waiting for my all stage 2 parts to come in. So I had the Impreza trunk lid and TS spoiler sent off to paint match via Goodspeed Performance Labs. Once those were done, and all the parts came in, we went a full stage 2+.

2/2/12: Scheduled 7,500 mile oil change

Car had noticeably more power in the lower rpms and held it a hell of a lot longer. Unfortunately, I was only able to enjoy this tune for about a week, before an Eclipse with a coffee can for an exhaust tip pulled on me from 60 - 100. I had my (ex)girlfriend in the car and was embarrassed to say the least. I just looked over at her and said, "I'm calling Goodspeed on Monday." Of course, the logical next step was E85.

I don't remember the actual date, but somewhere in here I purchased the TMIC splitter from Subtle Solutions.

3/13/12: E85 Tune (Mileage unknown)

Hella Supertones Installation
E85 tune by Clark Turner
349whp / 417wtq






As for power/tq mods, this is where the car stands now. It's so damn fast. So far the power bug hasn't come back yet. However, the appearance bug has got me know. So, here's what i did next...

3/22/12: Stock Enkei Wheels Powder Coated (using Subaru SWP paint code)



3/23/12: Yakima Roof Rack Installed







Now, given that my first NASAAZ event (HPDE1) had led me to boil my brake fluid, it was time to upgrade the brakes. I found a set of DBA5000 rotors for the front and a set of GiroDisc 2pc. for the rear in the classifieds over at iwsti.

4/23/12: Scheduled 15K mile oil change
4/27/12: Brake Upgrade

DBA5000 Slotted Rotors (front)
GiroDisc 2pc. Rotors (rear)
Racing Brake Motorsport Pads (Front & Rear)
Racing Brake Stainless Steel Lines (Front & Rear)
Motul 600 Brake Fluid (drained stock fluid & refilled)


(Stock rotors pictured on bottom)






My next track day was NASAAZ's event at INDE Motorsports Ranch on May 5-6th. I ran HPDE2 and the brakes were amazing. Huge difference. Fluid, rotors and pads changes everything when it comes to being able to stop at the track. Thanks again Goodspeed. My power and torque is still all there. Not a single car was able to make a pass on me. I'm pushing 23 pounds of boost with zero knock. The tune is amazing. Thanks again to Clark Turner.

I've got suspension mods and probably a set of Perrin spacers coming up next. Then who know. I'll keep this journal up to date the best I can. If you have any questions or comments, feel free to post.

Thanks,

Chris

Perrin spacers going on today.

15mm front / 20mm rear



Rear Spacers Install...

Wheel off, rotor hub lightly sanded and cleaned.


Inside of wheel lightly sanded and cleaned.


Spacer put on over stock bolts.


Provided nuts thread onto stock bolts, making sure that the hub is perfectly centered and that there's no gap between the spacer and the rotor hub, all the way around.

Wheel put back on...
Sent from my ADR6400L using Tapatalk 2

Tightened everyhing down well, took it for a 5 minute spin and saw and felt no issues, so I gave each lug another snug turn.




The measurement is perfect. Can't wait until Monday when the springs and front spacers go on.

Good job Perrin. I highly recommend these spacers... so far.

Ok so I've had the rear spacers on for a couple days now and I'm getting some fender rubbing on the passenger side rear tire when I roll over bumps. It's especially bad on the freeway. Perrin's website didn't say anything about rubbing on stock suspension!

Has anyone else had an issue with this?



Ok update. Front spacers are on, thanks to Goodspeed Performance Labs. the install is more involved than the rear spacers and I wasn't exactly prepared to pull off the rotors and all that. Also, I decided to stay on the stock springs for now.

Rear fenders had to be rolled to avoid tire rub. I think the Perrin 15 & 20mm spacers are spec'd for the '08 - '10 models, as I've read the stock suspension setup is different on the 2011's. This may explain why they're rubbing. Also, I'm not running the stock tires. I'm running BFG g-Force Comp2's, however they are the same size, width, profile as the stock Dunlops. (245/40ZR18)





I definitely like the look and the ride hasn't changed. I've already gotten a couple compliments and its only been 6 hours since I've had the work done. I still recommend these spacers, but if you've got an '11, you're gonna need to roll your rear fenders, even on stock suspension.

Interesting.

I'm kind of bummed to see that out '11 STI even with Stage 2 + all the other mods you added are only at 309hp on 91oct :\

I'm on 93oct with the OTS Stage 2 map and I've got COBB SF Intake, COBB Up Pipe, COBB Down Pipe and I was hoping to be over that mark :\

That fartcan eclipse that pulled on you was probably running a 20g setup which is very common in the DSM world, nothing to be ashamed of!

Thanks for the compliments guys.

I've had a bit of a set back in the last two weeks. Motor went and we finally found out today what happened. Well, I should say we found out what was causing my tuner to get zero compression in cylinder #3 after the motor began sputtering on me and my check engine light came on. I should add that the [s] and Cruise lights were also flashing. After doing some research on the interwebs, I found that this is the ECU's way of showing you that Cruise Control and Sport/Sport# modes have been disabled. Once I limped the car to my tuner, they pulled the plugs from cylinders #1 & #3 and found that porcelain from the plug in cylinder #3 had broken off. The initial assumption was that the porcelain had run through the cylinder and caused some damage. At this time the motor hadn't been pulled apart yet. I then called the service director at Subaru and, based on my description of the situation so far, he suggested I bring it in and have them pull apart the motor, which I did. The service director called me and asked me to come in and look at it myself so he could explain what he believes happened. The pics of the cylinder heads below are from today.

Blown exhaust valve in cylinder 3.




Here is an image of cylinders #1 & #3...


Here are cylinders #2 & #4, as a reference...


And this is the #3 piston head... I think.


I'm no mechanic. I'm just making an uneducated guess.

Ok, so SOA is going to cover the following...
8 exhaust valves
1 cylinder head
1 piston (#3)
plus gaskets, labor, etc.


Only thing is, SOA wants me to pay a $1,500 deductible and I have to sign a waiver stating to SOA that I've modified (or tracked) the car and SOA is no longer responsible for the motor.

Now, the service director says that the white residue on the exhaust valves pictured is due to extreme heat from running way too lean. He thinks the exhaust valve got too hot and blew, also causing the plug/porcelain malfunction. Essentially, they are blaming the tune.

My tuner says that cars on E85 always have that white residue. This is due to the high alcohol content, so they have far less carbon deposits (dark color) on the exhaust valves than a car that runs on pump gas. They believe that the Subaru dealer just must not see many E85 cars in their service bays. I would probably agree with that. My tuner has given us several ideas as to what they believe the culprit could be including, but not limited to:

Fuel Pressure Regulator Failure
Fuel Pump Failure
Bad Batch of E85
Fuel Injector Failure


Now the service director (with a self-proclaimed background of 20+ years experience at GM, which he says has the largest fleet of E85 vehicles on the road) says he's never seen that white residue before on E85 vehicles. Keep in mind that this service director also sees every car that comes into his Subaru dealership, including the tuned cars like mine, and I will say they get a lot of them. Not necessarily tuned on E85, but I sure do like walking through the service area when I'm there because there's always something in there worth checking out. I should give him some benefit of the doubt, as he's no stranger to modified cars and my dealer is SUPER mod-friendly. It was him who got SOA to cover what they're covering so far. With that said, he still believes that this is an AFR issue, he states that there are ZERO signs of detonation in cylinder #3 and believes the timing is perfect.

On the other hand, my tuner sees E85 setups ALL DAY LONG and my car was tuned conservative at 21 psi. If he says that the white residue is from the fact that that E85 has a high alcohol content and less carbon deposit, I'm pretty apt to believe him. They know my car down there and they know my tune. They say the AFR was dead on, then it was dead on. Also, I sent my tuner logs about a month ago and he said everything was fine. He even made a couple small adjustments to the current MAP and sent it back to me tuned back a little as the summer heat in AZ is hell on our cars.

I don't want it to sound like I'm siding with the dealership or my tuner. I'm just presenting the facts as I know them to be so far and I'm really just trying to find out what happened to make sure it doesn't happen again. My tuner wants to go down and take a look at the motor while it's still torn apart and the service director has agreed. I'm looking forward to it.

Feel free to let me know what you guys think...

I would kiss the service director at your dealership, I can't believe SOA is covering so much on a car that heavily modified

Wouldn't that be cool?

As you know, the EWG and TGV deletes are on the backburner indefinitely. However, I'm like $40 away from paying for the Process West TMIC. It looks like we'll have to figure out this rebuild first though.

I know right? He has been pretty badass so far. The only thing that is bothering me is having to sign the waiver on my warranty for future motor work.

You're lucky SOA is paying for any of it, if it's tuned and tracked, they typically dont pay for s#it. and the waiver thing sounds like a fair deal. Why should SOA pay for every STI thats tuned and beat? not saying you beat on your car, but subaru probably thinks you do....
