GMP Performance's 2008 Audi A4 Track Day Project Car

[GMP Performance]

One of the perks of being part of GMP Performance is our ability to go play on the track with our cars. We are a group of racing people here, many of us having been around tracks and race cars our entire lives. It’s a passion and one a lot of us share.

Another passion a lot of us share is a love for BIG projects. The more parts that can go into a car, the more excited we are for the final result. It consumes time, energy, money, and requires more than a fair share of sweat and tears but the end is always worth it.

Combine those together and you get this A4: a daily driver track car and our latest project.

This 2008 A4 2.0T was purchased by us to be a little bit of our everything; it’s a street car for our owner, a track car for our team, a R&D guinea pig for our shop, and a show car for our company when we go to events.

We have this running joke here that no one leaves their car stock for longer than 24 hours. The A4 was no exception. First thing we decided was to get some RH Wheels and a set of H&R Springs to add some extra style.

Step One: Style and Some Stop

Although the plan included only wheels and springs, it hit us that while we had the wheels and tires off anyway, why not take this time to address two big issues that would quickly come up?

One being camber arms. This set of our camber adjustable upper control arms would help to get the optimal camber setting for a street car that will be driven at the track. We wanted to put a little bit of negative camber so that we don't roll over the front tires and destroy the sidewalls.

http://gmpperformance.com/CFJFiles/GMP/Vehicle-Images/3516-10772.jpg

http://gmpperformance.com/CFJFiles/GMP/Vehicle-Images/3516-10823.jpg

The second issue we knew would arise was our brakes. Our stopping power would need to be amped up a good bit to handle the pressures of the track time we were preparing to throw it into. So we added it all: rotors, pads, a brake cooling system and new brake lines.

http://gmpperformance.com/CFJFiles/GMP/Vehicle-Images/3516-13166.jpg
http://gmpperformance.com/CFJFiles/GMP/Vehicle-Images/3516-13167.jpg
http://gmpperformance.com/CFJFiles/GMP/Vehicle-Images/3516-10825.jpg

We really like manufacturers that control their mixes themselves, from beginning to end. It's one of the worst scenarios when you can get a pad and rotor configuration that works wonders, buy a second set and they're totally different from the first. This is easily avoidable when working with companies that have the resources to decide everything, since the mix will always be the same or better. So we worked closely with two manufacturers to get both a set of rotors and a set of brake pads that would both be unfaltering in the quality.

Since we wouldn't be at big brake kit tracking levels just yet, we went with some direct replacement rotors that would breathe better and hold up to prolonged braking periods while also being great on the street. We added some stainless steel brake lines and bigger ducting system for additional cooling help.

http://gmpperformance.com/CFJFiles/GMP/Vehicle-Images/3516-13151.jpg

http://gmpperformance.com/CFJFiles/GMP/Vehicle-Images/3516-13169.jpg

Then it was on to the brake pads. And this is also where we were first introduced to what it truly means to have a "guinea pig" track car.

The first set of brake pads we tried were a dual-purpose street and track application, with a composition meant to maintain a higher temp with good stop and no noise... They failed miserably. Even for moderately skilled drivers, the car was just too heavy for the pads to handle. They were overworked in no time and they crystallized and glazed the rotors. They weren't much better on the street either, as noise was definitely present and annoying. Seems if we wanted multipurpose brake pads, we would have to have multiple brake pads.

Luckily for us, we knew some friends who could help us out. Working closely with their company, we developed a plan that would make the pads interchangeable. Their interchangeability relies on one fact: their mixture. There are 3-4 base ingredients and the % ratio in the mix of each compound determines and friction characteristics and temperature range. The base mixture of the pads is 60% similar across the board. The plus of that simple fact is that the pads are similar enough that you have the ability to swap various compounds on the same rotors without having any compatibility issues or separate set of track rotors. So we picked a pad with a compound suited for track and another with a compound suited for street. Another perk of these was the ease of changing them out. Swapping your pads is as easy as keeping the track set in the trunk, swapping at the track before your day, then swapping when you're done and driving back home on your street pads again.

We were getting closer to some serious play time. Now that the time had come for the wheels to be prepared for more than just the street, we bumped up their intensity too. Selecting a wheel designed for track usage (it's even named after a legendary track), the TSW Nurburgring wheel is manufactured using a production technique called rotary forging. The rim of the wheels is forged at high pressure while the wheel is spun at high speed. This strengthens the alloy and makes for a much lighter weight wheel, both major benefits to have on a tracking car. We added our classic GMP Tribute Stripes and, looks wise, it was track ready.

It seemed like the best time to add the APR intake we had planned, because even cars need to breathe. With improved horsepower, torque and throttle response for the track, and improved fuel economy for the street, adding the intake is a bit of a win win for both functions this car serves.

I need those brake cooling ducts. How can I buy a set??

[Charles.waite]

Wow. So looking through your gallery, the carnage in the teardown pics looks INCREDIBLY similar to what I found in my 2008 (http://www.audizine.com/forum/showthread.php/522046-Spun-Bearing-Bent-Rod-Advice-needed). Granted, I had no scoring of the cam bearings, thank god, but the damage in the timing cover and the debris I found in the timing chain area looks identical.

Did you happen to contact AOA about your findings? I mean it appears you were planning on building the engine anyway, but still. Maybe I'm just still bitter at AoA for telling me I was on my own with the repairs after I discovered this damage to my new to me A4 after only 1 month of ownership. I was not happy to say the least.

Anyway I just find it shitty that this exact same failure has happened to other 2008s even though its not covered under the extended warranty, simply because it came with "updated parts" from the factory.

/RANT

Nice build though. Excited to see what comes next!

So we had better stopping power, better breathing, and better looks, and took to the track. With lots of long-term big projects, every time you really get to test out your vehicle, you're always overly aware of all the little noises, the feel, the overall experience. You revel in the areas that are clearly improved but there will always be that tiny part that noticed the areas that are still lacking. And that's exactly what our track time did. The biggest area we noticed: suspension.

The H&R springs we had outfitted our A4 with were fantastic but for track times, the OE shocks just could not keep up. Like nearly everything else on this car, we spent a fair deal of time making sure that what we got would be multipurpose, like the car itself. That brought us to our good friends at Bilstein who made a kit that would not only help the shocks but also equip us with some progressive springs suited for what we wanted to do with this Audi.

Parts Installed:
Bilstein PSS9 for Audi A4 Coilover kit (https://gmpperformance.com/index.cfm?PG=detail&PID=54538)
Stern Audi A4 4 Cyl/6Cyl Pro-Mount Engine Mounts (http://gmpperformance.com/index.cfm?PG=detail&PID=231957)
JHM 4:1 Audi Center Diff Upgrade (Manual Trans Only) (http://gmpperformance.com/index.cfm?PG=detail&PID=265038)

Coilovers
Straight, or linear rate, springs are excellent for the track, solid and predictable, but stiff and there is a clear sacrifice in comfort levels. The plus of a progressive spring versus a linear spring is that the car will be responsive to what you're doing and react to match. It keeps the comfort as you drive about, day to day, but shifts to a more aggressive style when thrown into a situation where handling is the superior requirement. The PSS9s also come with the feature of a manually adjustable monotube gas shock absorbers, which features 9-stage precise compressing and rebound settings, from comfort to competition.

The Center Diff
During all this, an upgrade to the center differential came into the conversation. The factory differential on the A4 has a 2:1 torque distribution rate between the front and the rear. This enables the end of the car that still has traction (most of the time the rear) to deliver double the torque to the tires with traction. This set up is great for straight shot racing styles like drag racing but for a style that is defined by corners like road course racing, the guys are JHM have found that the ratio that excels is a bias ration of 4:1, similar to the RS4. Considering that road courses are what we do, this was a great upgrade for us to have.

Tracking It, Part 2!
After sending it out for modification and re-installing once received, we took it back out to the track to feel the progress and reassess our direction to be sure we were happy with it. We were. We could feel that the steps we had taken were improving the car big time and liked how it was both handling the track and the street.

http://gmpperformance.com/CFJFiles/GMP/Event-Images/FALLOUT-2012_1633.jpg

There was just one thing...

So far, the modifications we had covered handled a lot of the beginning stages of track-car improvement. Now that we were pleased with its current state, we knew the time had come for bigger leaps. That meant more POWER!

Maintenance Time
We wanted to be sure that the engine was prepared for our new plans, which meant maintenance and a good once over for the engine. We replaced the timing belt, water pump and valve cover seals, for security. We never like to just replace the belt so it was done as kit, complete with tensioner and rollers.

Taking out the old

One of the most frustrating things for any car owner is inspecting their car's engine and finding damage that was there before you bought it. A pre-purchase inspection is crucial but sometimes, even for us, a lengthy and thorough one can get overlooked for one reason or another. Sometimes, you get by okay. Other times, this happens.

We had tracked the A4 a few times and we noticed a faint rattling in the top end of the engine. The Audi was due for a new timing belt as well so it seemed like a good time to investigate while we were in there anyway. Initially, we thought the rattling was coming from the chain tensioner between the two camshafts and when we pulled off the rear timing chain cover, we found evidence that some sort of metal had passed through the cover, damaging it. Uh oh... Not a good start.

We then removed the camshafts to inspect for other damage and found that the camshaft bearing journals in the cylinder head had been scored pretty badly. We knew at that point that we’d need to replace the head. With this discovery, the decision to just rebuild the engine was made. The more we tore into, the more interesting things we found.

When we removed the oil pan, we found parts of a damaged high pressure fuel pump. What made this even worse in the big picture is that the pump that was in the engine wasn't missing any parts. We had to believe that the car had previously had a catastrophic cam follower/HPFP failure and somebody simply replaced the cam follower and pump without addressing the other damage. During the dis-assembly and inspection, we found the oil pump to had also been damaged by metal passing through.

On this engine, the oil pump is integral with the balance shaft assembly. We had heard about people doing a 1.8t oiling system conversion and upon investigating, we found the cost to be similar to replacing the OE pump, but with added benefits of removing the balance shafts and increasing the car’s oil capacity by over two quarts. Balance shafts are essentially big weights that are mounted on one side of a spinning shaft. They are there to counter act the engines natural vibrations and cancel them out. For a performance car, the increase in vibrations is hardly noticeable, but you get the same benefit as using a light weight flywheel by removing this rotating mass.

Since we were rebuilding the engine and adding a big power upgrade at the same time, we decided to future-proof the bottom end of the engine by using IE connecting rods and all APR hardware. While the stock bottom end will support up to Stage 3 power levels, anything more requires upgrades. By upgrading the bottom end now, we can later increase the power to Stage 3+ and beyond without needing to remove the engine again. Since we know we like to play and push our cars to the limit, it was a good move for us to make to pre-game for the future.

[ericpaulyoung]

Which exhaust manifold is that? Is it divided or twin scroll?

[LoKisSpYdR]

Wait! I thought Audi fixed the cam follower for the 2008s! [headbang]

Great build so far.

[ericpaulyoung]

Nope, they fixed it in 2009 :(

Mine is a 2008 and it has the old style cam follower. It is only when they went to the TSI that they use the roller follower.

[LoKisSpYdR]

Yeah I was being facetious. Charles just had that whole ordeal go down with his new advant. It sucks that Audi/VW won't take accountability for their faults, not that I want congress to attack them like they have everyone else (except of course Govenment Motors). Hell I just had my wife's 08 MDX serviced as Acura found some may have power steering pump issues, so we got a power steering pump and acessory drive service (including a tensioner) for FREE!

This. Its such bullshit. Seeing these pics REALLY maked me feel lucky that I found the errant pieces of my HPFP and follower. Otherwise I'd be shitting bricks right now thinking what surprises might lie in the oil pan. Hell, there might still be damage to the bottom end, I don't know. Its so stupid they wouldn't just cover the 2008 engines too. I mean the design isn't changed in any way. Revised parts, yes, but they only theoretically make failure less likely. Given the amount of 2008s I've seen recently on the zine with HPFP failure, its pretty ridiculous Audi won't cover them.

The time had come! We had torn our poor engine down, ordered all the parts we'd need and some extras, and prepped the car. Once the parts got here, we immediately went to work. We have an awesome event coming up, hosted by Grassroots Motorsports Magazine. It's called the Ultimate Track Car Challenge (many of you may already know about it) and we were determined to be there, just like last year. But, different from last year, we didn't plan to bring the S3. We planned to bring this soon-to-be bad boy. So with impatience and a lot of drive, we set to getting it better than ready!

We had tackled power upgrades. We had tackled engine security. We had tackled clutches and suspension kits and wheels. But our brains are always turning and there was still a few upgrades we felt our Audi needed before we took it to go play with the Grassroots Motorsports crowd...

Part 5 Coming Soon!

Yes it is unfortunate, but it gives us a good excuse to upgrade! [up]

With the Grassroots Motorsports Magazine's Ultimate Track Car challenge coming up in our horizons, we knew it was time to finish up on some little details, and get it prepped for its first tracking test in a good while. From the little details like gauges and trim we had started installation of getting finished up, to a bigger upgrade for our braking, we went to work getting our A4 ready to go test its new muscle.

Parts Installed:
JHM Solid Short Throw Shifter for 2004+ Audi A4 (http://gmpperformance.com/index.cfm?PG=detail&PID=280350)
P3Cars Audi B7 A4/S4/RS4 Vent Integrated Digital Interface (http://gmpperformance.com/index.cfm?PG=detail&PID=286445)
Audi A4 (B6, B7)/ S4 (B5) Front 6-piston 355x32 2-Piece Big Brake Gran Turismo Kit by Brembo (https://gmpperformance.com/index.cfm?PG=detail&PID=181241&VS=1)



P3Cars Gauge
We recently started carrying P3 Cars brand of gauges and once we saw these cool little things, we immediately knew we wanted one for the Audi. It fits right into the OE vent and become a discreet but very helpful part of your car's dash.

Interior trim wrap
Another thing on the to do list while we were already inside was the trim. Originally a classic wood trim, we wanted something a bit more fitting for such a hardcore car that this Audi was becoming. So we removed it all and wrapped it in carbon fiber vinyl.

Brembo front brake install
We were preparing to really push our A4 harder than the occasional track fun day and that would mean so heavy duty braking power. We loved our DBAs but since they are a direct replacement for OE, in order to get a bigger rotor, we had to go elsewhere. We went to a company we trust: Brembo's Big Brake Kits!

The Kit!

JHM Shifter Install
When it comes to track cars, short shifters are incredibly popular. We were no exception and got a JHM short throw shifter for the A4.

We actually did some testing on our in-house B6 S4 with a BBK on Friday, and we're pleased to say they fit [:)] Still working on getting everything together to sell as a kit though.

Do you have a picture of the windage tray before you put the oil pan on? Mine seemed to sit kinda wonky, so I took it out and the idle vibrations increase from extra windage. Definitely putting it back in soon.

I just went back and looked through our pictures that we have stored and not posted. I didn't see any of the the tray installed without the pan on, sorry.

We had two things left before track time: race seats and racing harnesses. With Recaro seats and some Schroth racing harnesses already in hand, all that was left was to install it all and then excitedly wait for the day to arrive.

Parts Installed:
Recaro PROFI XL Race Seat (http://gmpperformance.com/index.cfm?PG=detail&PID=87591)
Profi II ASM FE Scroth Harness Belts (http://gmpperformance.com/index.cfm?PG=detail&PID=281246)

We started by removing the back seats, a quick and super effective way to drop a lot of weight, and fabricated a temporary harness bar for the track event. Then came time to get the new Recaros in!

The Ultimate Track Car Challenge!! (https://gmpperformance.com/index.cfm?PG=aboutUs&Mode=view&AUGID=108)

The UTCC is always incredible fun and this year was no exception. This year, it was more than just fun for us; it was testing. This was the first time our A4 hit the track with all its new additions so we viewed the event as a critical learning experience. The car performed well and we got a great idea of where we were headed with the project. But mainly, we enjoyed every minute we spent with such awesome car enthusiasts!

Thanks for following along. The accident happened after a rain storm and the dry line wasn't as wide as the racetrack so it was the racetrack and mother nature teaming up on driver and car and won.

Sad to hear this about the B7.. So much work went into that car, as I know the majority of it was done at GMP for my car!. Was it a complete loss? Did you salvage any of the car, anything left?

Hey Chris, the body was totaled because the front of the car was pretty bent and we didn't want to track a straightened car. So we salvaged most of the suspension parts, big brakes, motor and trans as well as other goodies like the P3 gauge, JHM shifter, etc. We reinstalled the brakes, suspension and other accessories but never installed the motor and trans before we sold it to an enthusiast. We actually have the built short block and rebuilt trans listed for sale if you know anyone interested.

Thanks for the update.. Sorry to hear about the car.. As hard as I have been driving my car lately, I may take you up on the engine offer. I reached out to APR regarding.. new pistons, rings, rods . perhaps any engine upgrades, but I'm approaching 117K miles on my engine and I feel it will be next to go, would be nice to have another engine incase.

--I did want to ask, what was your peak boost PSI with the Stage 3 APR kit? I honestly never have been able to get past 21 PSI (any gear) until just recently. As you know I installed this kit with you guys quite some time ago. I always run 100 Race Fuel in my car from that Marathon station on Concord Mills, they are the only station I know of now the closest that has it available and isn't looking to run out anytime soon.

--Also Just trying to compare to what i've been experiencing lately. I did a boost leak test (30 PSI), found a small leak in the turbo, resealed it no change but then decided to throw in the newer revision PCV Valve with the check valve / N75 +new hoses + new gaskets, and I went from 17-18 PSI peak, to 24+.. quite ridiculous what proper maintenance, upgrades, advice (GMP) and Audi's can handle and accomplish. Hate hearing stories like yours however, there was so much work and time invested in your B7.
