That video is much better! So nasty! I'll be up at some point this weekend to check her out and lend a hand. I'll probably also be bringing my buddy Jimi who also has a VRT. I've been telling him all about the 200 and he's stoked to see it! Once again, good work!

So I was supposed to go home to VT for a family function over the long weekend, but a combination of things kept me from going, a big part of it was wanting to work on the Audi

I took over the shop Friday after work and occupied it until monday around 5. It was so nice to be working in AC, especially with it being 92* most of the weekend! I had the car running well enough to drive it to the shop but something was still off with the trigger angle, and I needed to install new control arms/ball joint taper bolts, new stretch subframe bolts, and new tie rod ends. I also decided to start painting the wheels because new tires for my other wheels are not in the budget before H20. Sunday Greg (gregdell1121) came over for about 10hrs and helped me get the suspension back together, get the trigger angle kind of set, and get some baseline tuning done on the car. He's been a great resource and help as he knows a lot about engines, standalone and such so it's great to have good help, doesn't happen a lot!




The passenger side tie rod end did NOT want to come out of its taper

I tried heat and a wedge-tool, eventually it just popped them apart so a lot more heat and I hammered the ball out of the steering arm once everything else was apart. And then thoroughly cleaned the taper hole



Don't worry about me, I've got AC

Measuring Crank/trigger angles

And now I need new injectors. Nick made up a conservative spark map for me, and it seems to be pretty spot on, haven't heard any DET yet but holy hell this thing wants a LOT more fuel than it did with the MAC-11 handling ignition duties... and it is significantly faster. I'm running 32lb@49.5psi (or something like that) Saab turbo injectors and with 60psi of base pressure I'm just barely able to get high 12afr's so this was pretty much the only beating it received last night. I'm going to try bumping them up to 65psi so I can hit the strip Friday. And that's MAXING out my pulse widths, although my duty cycle still seems safe, is there any way to change settings in Tuner Studio to give these babies a little more flow? Looks like next thing I'm going to be in the market for are some significantly bigger injectors. Hope everyone had a good labor day weekend and enjoyed a little bit longer weekend! Thanks for reading!

Thanks Ben! Not quite at 016-shredding levels quite yet. Actually, I have a question for you; when was your Holset hybrid making full boost by? And how much were you running when you exploded the trans? I'm curious because this thing has almost no lag and yours had that bigger cold side that might make a little more power down the road. Hmmm... Hx35 w/anti surge housing and silencer ring removed in this housing...
And yeah, Greg came over Sunday FOR LIKE 10HRS which was wayyy more than I was expecting and helped me put the suspension back together and get the trigger angle issue sorted.
Sorry Greg, I meant to give you props and then totally forgot in the midst of posting pics and vids, your help is seriously appreciated and I doubt I would have been able to take those videos without your help getting it going! Ben (the roomie for everyone else) and I are headed to 75/80 friday or saturday assuming I get a couple little things (alignment included) knocked out this week. You free? Bring the subie!!

haha you're very welcome Shawn. I had a great time lending a hand. Feel free to give me a ring if you need help, i know I'll be up very soon again to help out. She's a great girl that deserves good loving from all the men she can get haha. As far as 75/80 I'll have to see what my FAH MALE's schedule is looking like but I def wanna come and pitcrew for you. Oh and the subie has no boost and no ability to launch due to subaru's glass box they put in place of a transmission... = 15's at best haha

Shawn and I went playing around in the 200 last night and I'm not sure if the videos really show how hard the car pulls for 15 pounds or not but it really pulls strong and consistent! I have to say though I can't wait until we get some more hefty injectors in there and really throw some boost at this girl!

Thanks Dave! You actually helped me out twofold, that weird 3 part tensioner/adjustable threaded rod thing is now my alternator tensioner! Just needed to make up a 10mm spacer and it bolts up to the AC bracket, no second tensioner required!
On a related note I got 0-40w conventional for this oil fill up because it isn't meant to be long term and Greg mentioned he sees a lot more oil leaks with Syn than regular and wouldn't you know it my rear main isn't leaking NEARLY as bad! Not a solution but it's nice not dropping slicks all over the place and constantly adding Mobil 1!
Also, thanks for the vids Greg, got a bandaid in the works to keep the drag racing safe this weekend and then we hit the junkyard! I'll run 10 injectors if it means not having to buy a set!!

EEEERRRMMMMEEEEGGGGAAAADDDDD... Drag strip is closed tonight due to a power failure
Glad at least I checked before I drove the 45min there, nothing else has run what you brung tonight so I'll try for 75/80 again tomorrow. Glad I stayed up all night aligning the car, building circuits from scratch for the the fan, tach and meth into MS and such
Well, this way the car will be a little more tested tomorrow

So, overdue update from Friday night.. Best, worst night at the dragstrip ever. Turned out to be closer to a 2hr drive, and on the way there the car drove BRILLIANTLY. My Thursday night/Friday morning thrash got my radiator fan controlled by Megasquirt, added H20/Meth control and got a tacho output signal working. The only thing I didn't get functional was my fuel pump circuit, even with the key off the fuel pump circuit is grounded. I'm 99% sure this is a blown transistor as a result of my initial MS/relay board problems when I was first putting the car back together last fall. Either way, shouldn't be a hard fix.
Back to Friday, we got the car tuned up to ~17psi with my injectors running @67psi (Aeromotive FPR MAXED out) and thus flowing ~370cc I could barely keep under max duty cycle. Got the car tuned up and then turned on the meth and my AFR's were looking great, car was pulling like a banshee. Ride to the track ended up being ~2hrs instead of 1hr 20, we got a late start, and then sat in line for almost an hour and a half as they were only running one lane due to a diesel truck oiling the right one, then they tried to clean it up, closed the whole track, then only ran one lane again. It sucked. My first and only run I beefed the launch (left LC on too long), blew the meth nozzle out of the intake, threw the alternator belt, and short shifted/babied it to a 15.0@90mph. Then AAA'd it home, ended up being a 5-6hr trip for one pass. Could have been worse I suppose, at least I still have all 10 valves! The other guys we were with got a WHOLE 2 in the same amount of time. Don't think we're headed back there anytime soon
Obviously disappointing but oh well, the drive there kept the night from being a wash. With the meth on and cleanpull... well let's just say I'm excited to see what these babies can do tonight:

440cc @3bar Siemens Deka injectors, only took a couple hours of digging around the junkyard googling PN's to find a suitable set. They're Bosch EV1 style plugs, short bodies, and have extended tips, perfect for both fuel rail clearance and for getting down into the head like the CIS injectors did. I'm going to run 'em at 4bar for a total flow of ~510cc. 8 for the price of... well, let's just say they were cheap
FREE METH


Also, no pics but I installed a 4 Bar MAP DADDY sensor I got from Dana (bought for original DEATH4KTQ!) so +20psi is now within reach. Going out to tune tonight, I got everything back together yesterday, remounted meth nozzle, modded fuel rail brackets, fit new injectors, re did my tensioner setup and added a new alt belt. Everything was ready to roll but by the time I was finished up it was getting dark so I decided to wait and give it a once over in daylight before I attempt to start tuning. Videos later tonight!

Nick, if you build the Avant just think, you could whoop on everyone and then sprawl out in the back to rest up from said whooping you just administered!
Thanks Matt! It's getting there, my boss let me work late yesterday to pay off the meth injection parts I ordered from McMaster through the company so I didn't get home untill almost 10:30, but I adjusted the fuel pressure and got it idling. Something isn't right though, it wants VE values of 90 to stay idling @14:1. At one point I got it to idle ~50 but then once I changed a nearby cell it wasn't even idling in from 90 to 50 it wouldn't stay running. I'm guessing I overlooked something during reassembly but it doesn't seem to be anything obvious from the once over I gave it in the light this AM before work. I'll have a little more time to go at it tonight but my work environment has gone to shit the last couple days so there's a little alcohol induced relaxation on the schedule for tonight

My car was munching belts too. I've got everything nice and tight now and also perfectly aligned. That really helped and I haven't lost a belt since I put the motor together. I'm even running a wide belt. I like Hank's idea of a belt capture system, stops you from being screwed over.

Went to a narrow, slightly shorter Vbelt, not the one specified in that thread but seems to be working. I put it on, went for a drive, and re tensioned after a ride, all seems to be good with it. Still going to rig up a capture system for it and keep a 19mm with me at all times!
I'm not 100% why I was having problems... but they're gone! I think it was mostly getting a complete understanding of req fuel and how it affects things. Spent a little over an hour with the roomie driving, lost it all, went back out from 11:30-1:30 and got the car pretty well dialed in on boost. Definitely needs tuning around cruise but @~199kpa I'm seeing ~72% DC so I am set to turn it up
Going up to Dave (DE80q) in a little bit. Maybe, if I ask nicely, he'll take a video for you guys
Thanks for reading!

So still no videos yet, but I've been dailying the car since last wednesday and working on getting the tune dialed in. I had a misfire that I couldn't shake, on cool nights (when i have been doing WOT tuning) I could kind of tune it out on the fuel side of things and adding a degree of advance would help a little. On my way/at Dave's it was doing it very badly, so I decided to change my dwell settings when we went out to tune. Using the Bosch BIP373 driver I settled at 2.0ms, but I might revisit that. It stays a good temperature now but I had it at 2.2ms and it almost felt a little smoother there, although also noticeably warmer (still not hot). I want to do a little more testing with it.
A couple MS limitations I'm running into are the MSnS setup, meaning triggering and firing through the distributor and it's hall sensor. Especially when getting in and out of throttle quickly you can watch the distributor slack and then catch again (in TS or on a log) and can see some inconsistency even through a pull. Honestly though, I'm pretty impressed with the overall accuracy of it once you're in gear and making a pull, for that it definitely isn't too bad but I definitely plan on a VR sensor (or two) in the near future. The other is the resolution of the VE and spark maps. By no means have my capabilities as a tuner reached the point where I need more cells, but it would be much easier to tune it for smooth operation and good AFRs if I had a little more resolution down low. Realistically I should rescale the map, lose some resolution up top and add a couple Y coefficients in my cruise areas. Again, mostly an issue of me still learning the system and process but I can see how people knock that MS feature or lack thereof.
Local DRAG STRIP is finally open Friday, I've got the day off so I plan on being there when the gates open. On the agenda before that is to get the N75 I picked up today wired into MS and tuned and add a map switching circuit so I can have a lower boost/no meth tune for day to day and a big boost/meth tune for times like this. Both will be on 93oct so at least that's one thing I won't have to think about, I just don't have an infinite supply of the good meth and I've got it set to come on pretty early so it's at full tilt by the time I'm really in boost. While the ECU is out again I'm going to try and get the fuel pump circuit fixed, guessing it's a bad transistor that got back fed during my initially misassembled relay board incident, shouldn't be a hard fix. Also got a knock sensor to build a pair of knock phones at the JY today. Then I just need to fix the passenger window regulator, get the car together and tune like crazy Thursday and Friday
Sorry for lottsa reading, but I appreciate you dredging through it all!
