BeaterX: the whole story thus far
Spring is late but right on time for my budget 
Been slowly making plans for the next steps, all of which will be unfolding over the few weeks! Started with that DW300 fuel pump about 3 weeks ago. Car has been running perfect, like stock pump but with more fuel capacity. I finally got to turn the boost back up to 25-26 peak but still couldn't utilize my hybrid BCS setup due to my MAF being completely maxed out. If I did any tweaking at all to boost, it would invariably flatline at 5v from 6000rpm+ and no matter what I did there was this little boost spike at like 6500rpm.
With the added boost, I finally burned through this coupler that is who knows how old:
The car was at Primo for their up-and-coming 2.75" LICP (no pics yet sorry) and picked up one of their 3.5" intakes just today. I ordered a generic-sized aFe 3.5" pro-dry filter to go with it as it is IMHO an evolution of the tried-and-true K&N.
We had originally talked about them doing a custom intake for me to keep the stock BOV placement, but after thinking about it I decided to just go with their standard setup and ditch the like 30 feet of pressurized-hose from the stock setup.
This is a *really* nice piece! Install was simple, I did it over my lunch hour. I had my laptop with me and rescaled the maf initially to 1.48*stock maf tables. I tweaked to 1.45 and might drop to 1.43 to get it juuust right for my car. Higher was safer, so I started there, but all in all I have about 25 miles under my belt with it already and the car starts, idles, cruises, putts through stop-and-go traffic, and idles down my alley just like it did with the perrin/aFe intake: very very nicely!
We have a few fan shield designs to play with in coming weeks but its not quite warm enough here for necessary AC usage yet so I'm not too concerned. I'm stoked it uses the stock air scoop though.
For exactly two revisions of ecuflash, I'm *extremely* happy. Stock-like driveability, fuel trims are already down to -2.8%, afr's are nearly where I want them, and boost is a tish smoother (no hose going back into intake anymore, I think thats why):
Today is monday--saturday is the spring dyno day. I plan on tweaking AFR a tish more this week and seeing if I can't get boost to stay nice and level ~26psi at 8000rpm and see if we can't get into the 41x whp range at DB this weekend on just pump gas and the DW800cc injectors (which are just touching 100% IDC).
Next week (or I guess this weekend if nobody signs up for the dyno day), these will go in
0280158827 in da house! These are FIC 1680's, I picked them up with 100 miles on them from a buddy in chicago. Nom nom nom nom.

So, Primo came through for me with a last-minute surprise for the dyno day:
Introducing the Primo Performance 2.75" Evo X LICP
This is the coldside pipe on the X, wrapping around to the TB
The stock pipe is decent and I made great power on it, but I can't help but notice there's some subtle niceties that I really really like about this new, slightly bigger and smoother-bending pipe:
Mates right up to the 2.75" OD of the TB:
Utilizes stock mounting bolt w/ stock rubber mount:
Fits perfect! Comes with t-bolt clamps:
Got the factory air scoop to fit too!
Driving impressions:
holy hell, I honestly wasn't sure it'd make much of a difference. I was plesantly surprised to say the least! Off-boost in the 2500-4000rpm range the car feels more responsive and when boost kicks in I feel a definite bump in torque in the midrange!
The car feels great overall and while the boost curve is still not perfect, I'm able to hold 26psi at 8500rpm. PS I raised the rev-lmiter
See all tomorrow at DB!

1680's installed. Physical install was a cinch, took maybe 20 minutes; the fuel rail is right on top/front on the X so this was completely painless.
Initial settings I had from the guy I got them from didn't work worth a crap, the car idled at 8:1 and sputtered and died. Tried some more settings published on evoM with again, no luck. Then I realized that mrfred had posted some values from a car he had done with a cobb AP.
2.625
1.395
0.825
0.660
0.600
0.555
0.540
he posted E85 scaling: 943
Pump scaling I guessed, ~1.3*943: 1329
Last summer tephra figured out that the original algorithm used to display latencies and I could apply that and use mrfred's values for the cobb car. (link: https://www.evolutionm.net/forums/ev...hm-change.html) Still no luck. Car starts and runs good for a few secs above 2000 then as soon as it goes below 1500 it just goes pig pig rich again.
My logger is goofed up for some reason, but I'm thinking that the ecu simply won't drop pulsewidth low enough, so I applied tephra's minimum IPW hack:
https://www.evolutionm.net/forums/ev...ion-patch.html
Dropped MinimumIPW down one notch from .040 to .032. flash, start car, bam, ***in starts perfect, revs to 2000-3000 w/o any stumbling or issues, and it idles like a champ. Took the car around the 'block', initial short-term fuel trims look fine so I give it a few brief wot runs, just around 4000, into a little boost to check afrs.
Sad news, wideband in the car is flatlined at 0v again. No knock on the wot runs though, so I guess I'll just be driving around nicely and checking fuel trims until I get a new sensor.
*edit* hit the recalibrate button for the LC-1 and it's come back to life. I'll be testing this setup a bit until the tank is dry....then it's time to sell my soul to the corn gods :P
Oh also, changed the oil today. 3100 miles on this oil, the car didn't burn a drop. I don't say it often enough, but I want to thank MAP for a stout shortblock and DB Performance for a solid head. And while I'm at it, CBRD Speed Factory for such a bad-*** 100% stock-appearing turbo!
We'll see how well it holds boost once we turn it up to ~30 for the e85 tune.

May 17 2011:
Hell hath froze over! Hit play on this video before you scroll down much farther:
http://www.youtube.com/watch?v=Db1s-eV-Bd0&hd=1
Car was on E and flashing the gas light leaving my garage, drove about 5 miles and then filled up. I fired it up on the pump gas map then after about 20 seconds switched over to the e85 scaling on the alt-map. Drove around after filling up and dialed in injector scaling, settled on ~850 which still seems way low to me. Stopped by jim's house and we went for a rip. I logged and looked, the car is fine in midrange but lean up top, like high 12's. Gah! Also I smell fuel, alcohol fuel...fuel rail is leaking wtf!? Oh, one of the bolts is loose!???!
Yea, minor freak-out moment, but after closer inspection, I realize what I had sorta thought when eyeballing the new injectors: they are taller than stock. The stock spacers were just free to spin and the whole fuel rail was tweaked leaning forward, sitting cockeyed on the injectors. So I snugged it down for the drive home and then checked my garage for just the right spacer. I believe these are old metal center sections out of a 1G shifter base bushing or something, but they fit great! They're metal though, so I hope it doesn't come loose. Also I hope the rail not being ****-eyed helps flow and helps richen things up. I will report back!
Initial impressions--the car freaking rips on e85! I left boost alone for now, ~26psi across the board, and after initial logging, I added 2° of timing, it just hits 15°*at like 7500 or so, still very very mild but the car just feels smooth and powerful and absolutely no knock.

Oooh god I may really need that BAP sooner than later! Anna got me this for my bday:
Chad @ CBRD raves about these, if it can hold boost like a Ron-crushed stock bov but have the driveability of an uncrushed stocker, I will be a happy boy!

Took some long drives (with plenty of boost) this weekend to Northfield (college reunion) and then Wilmar (helped Kody reinstall his tranny), the car got 18.4mpg. Not bad I say!
In other news, BAP installed. Here's the package. Lots of wires but really the install is dead simple.
Goes inline with the power line to the pump:
And mounted in the trunk, I used a stock bracket, a big hose clamp, and some fuel line for a nice soft but secure mount:
All the wires heat shrink wrapped and sealed spade connectors for easy reversion if need be. I had planned on replacing the rheostat dial that lets you run stock voltage or up to 17.5v with a simple resister setup. Dan @DB says that is the only fault with these things, the dial itself dies after a while, so they usually just hardwire them to max voltage. I thought I'd go easy on the pump and use a 3.3k or 1.8k resister and one of these nice DIY RCA plugs, maybe run it at 15 or 16v:
But I did hook up the dial for initial testing, and I set it right in the middle. I didn't measure, but this should be around 15.75v to the pump. I just turned the boost up and let'r rip. It is not the most beautiful boost curve, but it doesn't matter, I have more fuel now
Again, ignore spool-up, these were started at different RPM. My main concern is 6000+rpm where boost is now 2-3psi higher and AFRs are about the same. YAY!
I am still pretty much maxing this setup out so I think I'm going to just crank the BAP to max and let'r buck. I have an appointment with Shane @ DB next Wednesday...

Ok, doing boost control testing I'm getting some inconsistencies--I'm trying to get it sorted. So glad I have e85 so a little more boost doesn't hurt a thing, and I obviously have enough fuel now with the BAP turned all the way up, and I even leaned the fuel map out a little This is ~33psi to just shy of 7000rpm tapering to 28 at 8500. Go 'lil BBX GO!
Again, different starting RPMs!
Earlier today I mentioned to Hughes that I should upgrade the fuse for the fuel pump from a 20a to a 25a or 30a...prolly not a bad idea right? On the way home from Wagner's tonight sure as ****, it blew and I coasted into robbinsdale. I swapped in a 30a when I got home
Did I mention I'm having a blast getting the car dialed in? 4th gear the car just ***in rips!

Update with dyno numbers!
First off, BAP is working like a champ. To clarify, it shipped with a properly-sized 30A fuse for the stock fuel wiring.
Next up, the Cobb BOV. This thing is smoother than a crushed stock BOV but is it really holding boost? I had been suspicious so I swapped my stocker back on just before I hit the dyno. AFR dropped nearly a full point on the street--this tells me the stocker is leaking. So I just left it on and after shane did a few warm-up baseline pulls I swapped the Cobb BOV back in with ZERO other changes:
So basically as it had been on the street (self-tune with some GREAT guidance from shane@DB) on the cobb valve it rolled in on ~460whp. Holy crap! I was so excited I couldn't believe it!
Shane made some changes to fueling to help address a part-throttle issue I had been having around 2500-3000 and tweaked timing slightly and that was about it.
Boost is about where I had it on the street with my hybrid MBC/BCS setup, the turbo is about at its limit from 6500+ as WGDC is pegged at 100%. I'm not trying to get a ton more out of it for now, this will be my every day tune as well as my drag/autoX tune. The car responds very linearly and the powerband is just wiiiiide and strong.
I'm very happy and I have some video that I'll post later.

So that gets us up to July 2011.
In other news, I have been enjoying the car on these longer trips...drove it to BIR and back two weeks ago and up to Fergus Falls (my home town) and all of the lake areas around it this past weekend for the 4th of July. Had a great time, gave lots of fun fun rides to friends and family, the car ran perfect, and e85 stops were not a problem anywhere.
On the way home, I feel some vibration...it goes away...crap! it comes back, I pull over, flat tire.
I see this hole, figure I hit something:
Pull the wheel off and see this:
Fuuuuck...I have about 10,000 miles on these tires and with all of the pressure checking I did at BIR I didn't get a chance to rotate the tires yet (I did at ~5000 last fall)...I should have, I would have noticed this earlier. I feel like an idiot. So I order a fresh set of sumi's and had Ricer Pete swap them for me. While the car is up there (Youngstedt's Maple Grove Goodyear) I have them throw the car on their fancy new alignment rack--there HAS to be something goofy with the alignment, I only have maybe 10k miles on these tires!
Please note the toe:
Good god I must have hit some crazy potholes this spring!
I saved my rear tires, they have 7/32 left on them, they will be a good start to my collection for road racing

Changed oil in the evo on Tuesday, drove it to work and back Weds. On the way to work Thursday I think it sounds funny, oil light comes on and I hit the ignition off instantly....coasted down to a parking lot and voila: oil dumping out the drain. I must not have tightened the drain bolt!
Got a new drain bolt and some oil and she sounds ok....hopefully no issues down the road, only 7500 miles on this engine. Enough came out of the pan and onto the lot that I think it'll be ok but man I'm neeerrrrrrvous.

October 2011:
Hrm, lookee what landed on my work bench this evening
These pics do not do this manifold justice--it is smooth and SO SEXY on the inside!
This is MAP's Rev3 port job. They cut open the plenum for maximum awesomeness of the port job, then weld it back together. Only thing I'm a little disappointed about, I was hoping to strap on a 64mm throttle body to this some day and ummmm yea. Hopefully my caliper is off (but I doubt it), it's just a cheapy.
The inlet is opened up to only about 62mm
I spoke with MAP and they assured me it would fit with a 64 so idk...my tools are not that accurate but whatever....I'll deal with that down the road.
Here's the stock TB, only about 60mm:
Quick rip around teh block and the car is leaning out almost a full point--that's a good sign I think

Added about .8AFR to my fuel maps this morning and the car no longer knocks at all. Runs solid like it should and the car feels great all over, but no amazing change from my butt dyno.
However....and this is FAR FROM PERFECT but if the numbers indicate gains across the board:
Also I now have a set of FIC 2150cc injectors...trying on if I want to install them and sell my 1680's or just sell them. Either way the money will go towards the new walbro DW400 fuel pump setup and a mil.spec 64mm TB....maybe by xmas? :P

Car rolled over 38000 miles as I pulled into the garage last night--this marks 10,000 miles on the motor since I got it running last fall. What an epic year it has been! The car is making fantastic power and I couldn't be happier with the drivability and day-to-day civility. The car runs perfect and last weekend Andrew complimented me on how clean the car runs under boost--no puffs of smoke, no drops of oil flying out, etc.
Today I decided to give it a health check. Engine was up to full temp but oil temps were probably not too hot as I only drove over to the dog park and back.
Compression test:
145 147 138 127
147 149 139 130 (retest)
This spring I had tested it out at 145-151-146-145 so I'm not sure what to think.
Next I yanked the valve cover off and check the clearances on all of the cam buckets. All are within spec except intake cam lobe #3 (cyl 2, intake valve #1) which is .012/.013, this hasn't changed since I checked it at 1000 miles.
Checked timing chain stretch, it's well within spec.
Spark plugs look ok, probably will replace them next spring.
Boost leak test and oil change are on my todo list, maybe next weekend. About time to order snow tires to I guess :P
