I did a little road trip to the wilds of NY State yesterday and visited with Bruce to check out his project. All I can say is, wow, what a fabulous pile of cool stuff waiting to go in and on! Except maybe that B&B melon shooter which, visually at least, is (pardon me Bruce) completely over the top. (After meeting Bruce & Friends I'm certain that the outrageous exhaust tip diameter is perfectly fine with him!)

Besides all the new bits like Crawford pistons I got to see Subaru camshafts and other bits of our cars that are normally quite well buried under various covers and gaskets. I am even more impressed now by the engineering and quality of these cars than I was before. I was hoping to see Subaru pistons too but a lack of very specific tools put an early end to the day's teardown festivities. Also, despite (or perhaps because of) the efforts of several folks, the ongoing oddities with the webcam during the 4:20 reports remain a mystery.

Besides Bruce I also got to meet Rick, Dan, Pam, and a steady stream of other folks whose primary link appears to be an irresistable urge to jump out of perfectly functional aircraft. All great folks. Thanks to everyone for being so friendly and making me feel instantly at home.

Depending on the day it happens I plan on being there to see the initial fire belch from the reconstructed beastie. If I enjoy myself half as much as did yesterday it will be well worth the trip.

Cheers!

going to keep track of this post......

Cheers!

thanks for all the kind words, wdb. we enjoyed having you and really hope you can make it up again when we spank it to life.

day 11 as the motors hang...some more

hanging on one stand is the old motor powerwashed and scrubbed. the s4 is hanging on another stand ready for the head swap to start. unfortunately, we need 13mm and 14mm 12-point sockets to remove the heads. we expect to have them tomorrow but we won't be back on it until sunday at the earliest. little ricky is ...er...pacing himself (isfh) and i have a skydiving event this weekend.

element is shipping the turbo kit including the intercooler piping for the dr725, the uppipe, downpipe, intake, and the gt65 on monday. we should have it by thursday. the gt spec subrame braces have been shipped. except for a few odds and ends from local parts stores, these are the last parts we need to complete the puzzle.

day 11 pics:

- the engine bay is sparkling.
- the e-boost controller, fuel pressure and egt gauges are dropped into the lotek a-pillar, which has been filed out a bit to accomodate 60mm gauges.
- the tumbler deletes are almost finished. as you can see, the empty holes that used to hold the flapper rods still need to be welded and the ports tidied up and matched to the intake manifold. flow baby flow.
- two shots of the right-side head without the valve cover. you can see the water and oil feed lines to the stock turbo in the upper left frame and a nice close-up shot of the cams

day 15 - 2:45 - webcam is up for the head removal

on camera - little ricky and i spring into action {{yawn}}

the gt spec subframe braces are here. the element gt65 turbo kit was shipped today. once it arrives, that's it. everything is here.

words cannot express my disgust at the condition of my combustion chambers including the heads, valves and pistons.

so, you think you are running rich with accessport? i used to joke about what my tailpipe looked like.

here's what we found. i hope the pics i just took do it justice.

pics posted above are the 1 & 3 cylinder. the 2 & 4 cylinders are just as gross but with a little more crap broken off and piled up on the cylinder wall.

Bruce, is the crap built up on the combustion chambers a result of the AP?? I don't think I've ever seen an engine look so nasty before.

the license plate holder says "cobb tuned"

9.8-10.2 AFRs with > 100% IDC in many places. Definitely not acceptable. However, it is extremely important to note here that Cobb's maps are leaner than the stock maps! IMHO, what you are seeing could absolutely have been worse had you not been running Cobb's maps. The stock maps are definitely richer ... I can post pictures of each if you would like so as to offer proof of that statement.

AFTER tuning I put the AFR around 11:1 and had 90% IDCs.

That graph is a little difficult to read in comparison from what you might receive from a tuner for an AF ratio. i.e. A single dyno pull showing AF ratio from like 1500RPM to redline. Have anything like that?

In the AF graphs I've seen (mainly 04s, maybe all 04s) the car does NOT run that rich. Usually starts at 14.5:1 or so and tapers to 10.2:1 or so. 9.8:1 seems ridiculously rich. Regardless, what your graph doesn't show is the AF ratio over the entire powerband.

Hmmm. It's been a while since I pulled heads off a car, but for 40,000 miles that engine looks pretty darn clean. Hardly any buildup on the pistons or valves at all.

As for the black stuff -- like I said, I haven't pulled heads in a few years, so my knowledge is a bit rusty, but it looks like there isn't very much of it at all. One piston has a spot where you wiped it right down to a clean piston top. I wonder if that amount could build up by starting up from cold and idling for a few minutes, then pulling into the garage.

First of all, it depends on where the wideband is placed. If you are on a dyno and they stick the wideband up your tailpipe then forget about it ... it is going to read leaner if you have cats in the system. You can't trust that value if the wideband is behind the cats. Want some proof? Sure. Here is a dynojet dyno with wideband on my stock car. The wideband was placed in the tailpipe behind the factory cats. Lower than 10:1 AFR and this was AFTER 2 cats. Stock fueling on the '05 is richie rich beyond compare. At least Cobb does lean it out some!

As far as the graph ... I didn't do a run with the intention of graphing something for general consumption. I had a WOT run on my laptop and decided to post it so that others could see. If my intent was to show AFR over the powerband then I would have done what you suggested and started in 4th gear. But, alas, this is an afterthought.
