2004 STi Twin Scroll 6262 by Layvon

9 minute(s) of a 190 minute read

Well, I am as ready as I can get to go to P&L :

Car will be there tomorrow around the time they open. Hopefully they can give er a once over and do the PDI before tuning day to make that day go smoother.

Just in case **** hits the fan, I have everything I need to do small fixes in the parking lot. I wasn't paying attention enough when I was changing out my transmission fluid, I poured 4 jugs in when it was still on jack stands thinking I would top off the rest once level. It is now it is a fuzz over full, so hopefully the PDI involves putting it on a lift so they can quick drain some fluid out so that it is where it needs to be. 

Excited, nervous, and provided it makes it there, it is out of my hands.

Tune is the 25th at 2pm CST

Car is in P & L 's hands. Should get the pre dyno inspection tomorrow.

Good news today, I learned a lot about how Subaru motors work and why things work and what things don't. I think the biggest thing I learned is that there's no such thing as being too anal.

Something is going on with the injector so I'm going to send them into fuel injector clinic to get tested in the meantime buy some ID 2000. 

We're having issues getting it to idle and so we opted just to bag it for the night, never even unlock the rollers. Sorry for the lack of a fun update but sometimes that's the way the ball bounces

Yeah it is a bummer, but it isn't the end of the world. You made out a little better than I did because at least you left with a functional car but when I go down in March it'll be fine. 

I am still being optimistic about the whole thing. 

We fiddled with it for probably about 2 hours or so . . If not more, I don't know I fell asleep sitting in the chair for 5 minutes or so. Junior isolated the problem by shutting off individual injectors and then seeing if he can get it to idle, when he shot of cylinder two injector it would Idol at about 14afr.

Just got off phone with fuel injector clinic. 3 Injectors were at 2050cc and the other one was 2175ish. The nominal flow was supposed to be 2150.

I'm waiting for a full diagnostic sheet on monday.

3/11/2013

just got everything all buttoned up tonight. Allan and I chatted on the phone, he had a pretty good day. We shall see how it goes tomorrow.

My prediction:

496 - 93

592 - E85

Junior will be deciding factor in how he feels its going. I want a solid "safety" margin. At these power levels nothing is a guarantee so i have my fingers crossed.

3/12/2013

Made 468/370 on 93 on 20-22 psi, I dont exactly know what. Dyno will be posted tomorrow hopefully.

Had a fuel fitting fail because I was lazy to make it right and didn't even cross my mind till fuel crossed the floor. I will find out where / what the issue was and go down to get tuned on E85 this summer after our house is purchased and settled.

Had fun with the P&L Crew again, and Kathy made some good cupcakes regardless of what Dylan says!!  

Should give Junior some ammunition for in the morning.

I am going to have to ask Junior before I start handing out information. I don't think it will be an issue, but I want to make sure that he's cool with it. 

Here are some videos

Just for ****s and giggles, I called PT to see what they had to say. Grant @ PT was pretty stoked to hear 470 at 21psi on pump gas. He said on a 2.0 liter that they test on ( I dont know what motor platform, I'm guessing Evo) that it is efficient at 30 PSI. 

For my motor he said that it would be a little bit less, 25-27 psi. . . So like you said Allan, it the turbo will shine on E85. I couldn't be happier with how things are panning out. 

Fittings are ordered so gotta get that **** welded and ready to rock.

3/16/2013

Well... car is a riot. 

My buddy welded up the fuel pump assembly and it looks sexy as hell. Linear power is fun

Yeah she is fun. The cold air (19°) has it getting a little boost happy and hitting boost cut, so Junior suggested dropping wgdc in affected areas. I will get some logs tomorrow to show spool and stuff. Im curious myself.

90-110 miles today. It was a good time by all involved

3/17/2013

Not a complete log, but here is a screen shot from today. 

I'm not sure I'd trust my wideband AFR, I put a new one in, but I'm still having the same fricking issues getting the gauge / comptuer to match up. I'm thinking a Innovate is going to be purchased after this house, and I can mount a AEM Fuel Pressure gauge in the Apillar, because I'm anal about matching

You can see that I hit boost cut right there, . I'm adjusting WGDC right now to try to fix it.

I'm liking that 28% IDC. Overbuilding is nice.

Also - Here is the fuel system updates

3/21/2013

Did some pulls tonight. Input real data as much as possible into VD. I'm assuming that I weigh 210 right now, which is probably a bit too nice. Also assuming that VD has the weight of an 07 STi right because I was too lazy to verify.

Notice that the dips are gone also. At 0 smoothing they were still a little apparent, but not as bad as the dyno graph.

I had to stop. Snow is falling I felt er getting a little slippery.

3/24/2013

On that tank of fuel made it like 265 miles which was about 22mpg. Thats 100 miles of 60mph roads and the rest freeway/flint. 

Wont have many updates this week, leaving for Louisville tomorrow at 8am.

I need to get a few things situated on the car:

- idle after driving dips way low, like pulling up to stop sign

- knock setup 

- fender liners replaced

- headlights wired up, cause right now all i have is high beams

Small update :

Not related to the motor or performance but some protection for my tinted windows. 

I have a Beltronics STi driver and have had it for a while and love it. The speaker pooped out on it about the time i started my build. I couldn't find an internal speaker for it so i bought the external for it. Wow. Loud. 

I had my radar detector powered off the map light switch on the left, and both lights powered by the right. Junior had fun with that. ... one of the funnier moments on the dyno. Today, i moved the power to the gauge power source i have so that it is on with key on.

Thankfully the speaker came with a super long plug into the side of the radar detector. (3.5mm plug) i put the speaker in the vent passenger side by the hazard button. 

Once i got everything tested it was time for reassembling of the interior. Since i didn't run the speaker wire before hand i had to fight it, which sucked.

Now that it is done, im glad. ...

Tomorrow is the day to get some LC setup. Track sunday!!

4/7/2013

Well... No track update today, apparently they thought it was too wet, I found dry pavement all the way to the track when I found out. 

Cooked another wideband today practicing a launch. Getting really pissed about that. I dont think my sensor mount is vertical enough, so it is going to get shifted next weekend to completely vertical. I'm tired of effing around, and am ready to get serious... I might even move it back a few feet just to make sure. After doing about 3 hours of research tonight, these sensors dont like to be run richer than 10, which I see on occasion, so that probably doesn't help anything.

I also think I am going to install this to make sure that I dont have any more oopsies. 60 dollars a sensor will make me run broke. Innovate makes this, and sense they utilize the same sensor I figured it would be worth while.

For those that dont know, little insert not only shields the sensor from water at cold start but also helps cool the sensor and sensor body itself. If it saves one sensor it paid for itself.

Bah. I really wanted to run today.  I found out I need to work on 4 things while practicing:

2-3 Shifts.

Balls to take it to 7k. 

Launches obviously

and making sure I lift 100% of the way.
