Quattromog #2: Bolt-on's

Right, so my wife and I took Quattromog out for an epic weekend of four-wheeling and camping a few weeks back (i'll post more about that on the Quattromog thread). On said trip we were reminded just how quickly the two of us fill up a coupe with gear for a weekend. That has not been an issue until now, but...

The problem: My wife is pregnant - come November there will be THREE of us!

The solution: Quattromog XL!! (Open to naming suggestions.. I don't love this one)

Wife has dictated that QXL must be ready to take us and the baby deep into the forest service roads for Christmas Tree Hunting in December. The pressure is on.

Next question: What to use as a base

We already have two 2011 A4 avants which we love, so the natural choice was to buy a third one to turn into Quattromog XL. Completely normal to own three of the same car. This should give us plenty of space for ourselves, kids, and gear for adventuring.

Desirable features of a B8 Avant:
-Already has a 4-cylinder turbo
-8 speed ZF gearbox (best auto I’ve ever driven)
-lots of space
-AIR CONDITIONING!!!
-a nice quiet interior with all the modern comforts you’ve become accustom to in your ‘normal’ car

Undesirable features of a B8 Avant:
-Pre-oil consumption pistons/ring

Like the original, I’m not going to ruin a “nice” car with this project, and I found the perfect candidate on Craigslist for cheap. Behold!

Image

Image

Image

Don’t let those flashy listing photos fool you; the previous owner was a professional photographer. The windshield is broken, paint is hammered, there is not a straight panel on this thing, it has a salvage title, and the engine is toast (zero compression in cylinder 1).

It’s also the most base model B8 A4 I have EVER seen. It’s missing thing I assumed were standard equipment because I’ve never seen a car without them before! It has halogen headlamps! No reverse sensors! No backup camera!!l The humanity!!

On to the work.

First up: engine replacement
Bought a used motor from a wrecked 2011 A4 sedan. I called the dealer and checked the car’s VIN to confirm the oil consumption warranty work had been performed (it had) but when the motor showed up- surprise! Not the original engine for the car. The ‘new’ engine from my donor A4 was actually a 2013 Q5 engine. Happy surprise as this means it has all the updated pistons, rings, and timing components, and (hopefully) lower miles.

I’m getting faster at this swap: started at 3 PM and finished at 2 AM with an hour break for dinner

Image

Image

Image

Next up: suspension
Eventually I’ll probably build custom suspension to get more lift and travel, but in the short term I want something easy to get me more ground clearance. Allroad springs were my first thought, but those only get you 1.2” over a standard A4.
With some digging I discovered the B8 A4 is part of Audi’s MLB platform which also includes the A5, Q5, A7, etc.. The suspension on an A4 and a Q5 are identical with the exception of the springs. I even called Bilstein technical to confirm shock valving is the same between the A4 and Q5.
Doing the math to account for differences in tire size, I found the Q5 suspension is only 1.2” higher than a standard A4; same as an Allroad.

Image

Better than nothing, but not great IMO.

Then I found that H&R makes 1” lift springs for the Q5, which by my math would mean 2.2” lift on an A4. Sweet!
So I bought a set & installed them. Fit like a friggin’ glove.

Image

Image

Image

Image

Image

These are before I took it out for a drive to settle the suspension, but first impression is very good. I’ll get a measurement later to see what the total actual difference is. First impression driving is that the car handles well and does not feel like it’s over-sprung, however it definitely handles like a road car. I don’t suspect these will do me any favors in improving suspension articulation.

Image

Image

Last bit of work completed was a full brake job. The old ones were TOAST!

Did some measuring and comparison after driving around to settle the suspension:

Image[/url]

The springs did not lift evenly front to back which is a bit strange, but the average is exactly what I calculated it should be at 2.2"

Rear Lift: 1.5"
Front Lift: 2.5"
Lift at center line: 2.2"

Image

Ordered a good pile of parts this morning, including wheels and tires, so this thing should come together pretty quickly here.. maybe even by next weekend!

All good suggestions! I’ll know it when I hear it.. I feel like all lifted Audi’s are Quattromogs or at least belong to the Cult Of The Quattromog.

I like Tallroad

I had a 2011 Avant as well. great cars!

Mine was that metallic brown with tan sport seats. I wish I hadn't sold it. I didn't even have it a year and decided I needed a super fancy F150 instead at WAY more cost

Me too! I just did a search and it looks like someone is already using it for their C6 Allroad on IG, so it's unfortunately out.

The sport seats are excellent. I finally just got a beautiful set for my daily after lusting over them for years. Came from the same car that donated it's engine to this car. Dude was going to scrap them!

It's not too late - you can always trade back to one! (and probably end up cash-positive on the deal with the truck).

I'm leasing the F150 so I'll have it a couple years. I have a lot of basement rehab in my near future so I knew I'd need a hauler. When that's all over with though...

More progress!

The "new" engine didn't come with a turbo so I'm using the 135k mile unit original to this car. First drive it was pretty obvious the turbo was not working properly, and I got an error code telling me as much after about 10 miles of driving. It's not uncommon for the wastegate linkage on these to wear and get sloppy over time. Net effect is a wastegate that is always partway open so you never make proper boost.

The last one of these I fixed by machining a new linkage piece and welding it on, but in looking at forums this time I saw someone who had a clever idea of just cutting 1/4" out of the actuator rod, threading it with a 1/4-20 die, and reconnecting with a coupling nut. Cost $0.20 and an hour of my time (I have fat hands..) and suddenly the car feels like it has a turbo!

Image

Drove the car more and while it felt better, it definitely did not have the same power and throttle response as my other two B8 wagons. After about 30 miles I got a code for catalyst efficiency. Visual inspection confirmed the catalyst is mostly occlude; no wonder this thing couldn't breathe!

Image

I was already planning on getting a tune for the car, so since I'm replacing the cat decided I might as well go with a high-flow cat unit and set myself up for a "stage 2" APR tune for some extra power & torque.

A good friend of mine worked for APR and designed their B8 downpipe. I got to tour their facility in Alabama and see the production line he set up. Very cool. The quality of the hardware and welding is impeccable. Unfortunately (for me, great for him) he now works a SpaceX so no hookup on APR parts. As cool as it would be to have his parts, I'm going to have to save that for my daily and go the budget route on this one: 034 HFC for almost exactly half the price.

Quality of the 034 unit is reasonable. The welding is nothing to write home about, but fine for the price I guess.

Image

Image

Image

Got it installed and it's a totally different car. It's gone from laggy & slow to very peppy & responsive. Better than my other two B8's... hmmm....

I digress. Next up is some exterior stuff.



Roof rack!
Yakima Load Warrior basket w/ extension to maximize that nice long roof ;)

Image

Windshield!
(the original was very broken, all over)
On a side note, Safelite mobile service is very worth the $40 or whatever they charge. I went to a Safelite shop for OG Quattromog & it took damn near 3 hours plus driving down there. This time the dude came to my house & was done in under an hour. Brilliant.

Image


Lights!

The cheap-o LED's on the OG Quattromog are bright, but not terribly useful for night driving. They scatter so much light the reflection off the white hood is almost blinding. I took that lesson and bought real driving lights with a focused beam pattern this time. Hella 500FF's.

Image

Wiring for the lights is about half way done. I just need to mount the fuse/relay box somewhere and connect it now. Factory fog lights are likely going away so there is a good chance I will wire them to the fog light switch to avoid extraneous stuff on the dash.

Hopefully more to come later this week.

Anyone else having trouble getting a new post to process? I wrote out an update and have been trying to post it for two days but keep getting an error. Maybe its due to photo links since editing this post seems to work fine with just text?

I emailed the Board Admin email address the other day (theprojectpad@theprojectpad.com) & got this bounce-back message:



The response from the remote server was:

Who is an admin and can help fix this?


EDIT: FIGURED IT OUT! I typed the update up in word, which auto formatted in some special character in the text body. Removed that and it posts just fine.

Wheels & tires showed up this week and as expected some fitment work was required. My goal was to get as much sidewall as possible, which means the smallest wheels possible. Very un-allroad like ;)

The B8 came with optional 16” wheels in Europe, but not in the US. Unsurprisingly, the selection of available 16” wheels with a 66.6mm bore and 5x112 pattern is slim. There are a number of extremely ugly cheap aftermarket wheel options, but only one good one I could find. Here are the specs I ended up with-

Wheels: Motegi Racing MR141, 16 x 7.5 ET 40
Tires: BF Goodrich All Terrain T/A KO2, 225/75R16

For comparison of these vs. the stock wheels and tires-
Image

I was a little unsure on the white wheels, but now that they are here I’m very happy with the choice

Image

Running 30mm H&R spacers to push them out. Front mounted up OK with just slight trimming of the fender liner on the front edge.
Image

Image

Image

Image

Image

Rear is a different story altogether. The rear wheels move forward in droop and rearward in compression. At full droop there was a hard interference with the fender opening and end of the rocker.
Image

Image

Through judicious use of a BFH I made a few inches of room & solved that issue. Not the most elegant, but effective and fine for this car. Here is the process in photos-

Image

Image

Image

Rubberized coating to seal it back up-
Image

Fender liner back in (opposite side)
Image

Image

Image

And on the ground! It definitely needs more lift, but overall I think it looks freaking fantastic.

Image

Image

Image

Image


Drove it to work today and it did great. There tires are waaaay louder than the summer only tires on my daily, but not terrible. I notice it for about the first minute of driving then tune it out.

After work I did a flex test to see what it would do in current state. I was expecting maybe 8-9” and was amazed when it measured out at a full 12”. Interestingly the car seems to have a near perfect crossweight; opposing front & rear tires come off the ground at exactly the same time doing this test which is a very different result from the front-heavy CQ.

Image

Image

The test was in my garage so I was very caution on the throttle, but interestingly forward motion seems to cease as soon as the two tires came off the ground. I expected the traction control to start applying brake to the two free wheels and keep power to the two planted wheels, but that’s not what I felt.
Should get some light offroading in this weekend so I will give it a real test and see what happens. I’m excited to see how it does.

:lol: quattrostilskin is pretty excellent. Somehow it's funnier every time I read it..


Finally getting around to that long overdue update. While my priority list for having a baby is building an offroad avant, my wife's list a bit different. In the last two months we have:

1. New roof
2. Repaint the exterior of the house
3. New gutters
4. Scrape popcorn ceilings, smooth
5. Repaint entire interior of house
6. Move gear room to basement
7. Turn old gear room into baby nursery

I'm tired. But I have a new house!


Moving on to the fun stuff: driving across the state for a long weekend and some (very) light offroad testing in eastern Washington.

Luxury accommodations
Image

Nice Views
Image

And the part I was really curious about- testing how this thing does on three wheels
Image

Image

Image

Image



All in I was very happy with the performance of this thing. The EDL (electronic differential lock) quattro system is this car is very different from that in the coupe. With this thing I have a “crown gear” center differential which allows for greater torque vectoring front/rear than a Torsen, and open front & rear differentials. Like pretty much all modern traction control systems, EDL uses the ABS system to monitor wheel speeds and vector torque as needed.

The coupe’s Achilles Heel is trying to climb with one of the front wheels in the air. Because of the open front differential, the free wheel spins without resistance rendering the torsen useless and the car goes nowhere. I figured that scenario would be a great test for the EDL system to see how it does in the avant. Result: it works! I slowed down the video during that section and you can see the EDL system in action as it brakes and releases the free wheel. Pretty cool!

Bumper and skid plates are moving up on the list for this thing. With ground clearance where it is with this thing right now I cant get too rowdy without major risk of spilling it’s guts.
