Sonu Atwal’s B5 S4 K04 Sedan – 034EFI Motronic Tuned

March 2nd, 2010

Sonu Atwal had been a long-time 034Motorsport customer when he picked up his latest project, a B5 Audi S4 Sedan that had been modified by the previous owner. The car already came with another company’s full RS4 K04 turbocharger upgrade kit and tuning, as well as full downpipes and exhaust. Despite the existing modifications, he wasn’t satisfied with how his new ride was performing.

At first, Sonu’s plans were simple: install a water-methanol injection kit, and have us calibrate it on our dyno. Even with the newly installed WMI kit, his car wasn’t making the power that it could be. The lack of power and other issues with the S4’s idle and part-throttle driveability sent him looking for other options. Sonu was already familiar with 034Motorsport’s tuning prowess, as we had spent some time tuning his 034EFI Stage IIc equipped big turbo B5 Audi A4 1.8TQM a while back. Convinced that our tuning could get his S4’s performance to his expectations with the current hardware, Sonu considered getting another 034EFI Stage IIc Standalone ECU for his new toy, but we offered to optimize the tuning on the stock ECU. We both agreed this would be a great option for the project.

Luckily for him, we had been tuning factory Motronic ECUs for years, and his car was the perfect candidate for our ME7.1chip tuning. With only a few minor changes, including our 85mm billet MAF housing, silicone RS4 MAF hose, 3 BAR fuel pressure regulator, and larger 630cc injectors, we were ready to start the tuning process. We also added our Bosch 044 drop-in fuel pump upgrade for safe measure, to ensure that no drops in fuel pressure would occur and cause the engine to run lean.

After a few hours on the dyno, Sonu’s car was tuned to perfection. In addition to having a butter-smooth idle and perfect driveability, our tuning also picked up over 100 ft-lbs of torque and 78 horsepower at the wheels! Sonu was ecstatic with the results, and couldn’t wait to drive his reborn S4.

This B5 Audi S4 is the perfect German sports-sedan, comfortably delivering 500 horsepower of driving bliss with uncompromised driveability and reliabilty. Keep an eye out for Sonu and his S4 in the greater Bay Area… You probably won’t see anything except for a silver blur unless he’s stuck in traffic or stopped at a red light, but if you’re lucky enough to keep up, you’ll be able to recognize him by his permantent horsepower-induced grin and full-034Motorsport shwag.

This vehicle features the following parts from 034Motorsport:

  • 034EFI B5 S4 K04 630cc Chip Tuning
  • 034Motorsport 85mm Hitachi 2.7T Billet MAF Housing
  • 034Motorsport Silicone RS4 MAF Hose
  • Siemens-Deka 630cc High-Impedance Fuel Injectors
  • 034Motorsport Drop-In Bosch 044 Fuel Pump Upgrade Kit
  • 034Motorsport B5 S4 3″ Stainless Steel Downpipes & Midpipes




  • Anthony@Audizine’s UrS6 Avant – K26/GT3071R

    February 28th, 2010

    Last week, we were given the opportunity to put our hands all over Audizine founder Anthony Marino’s beautiful UrS6 Avant.

    Anthony's UrS6 Avant Header

    This was really a special project for us, being that Anthony has had his UrS6 serviced here for years, and he’s always managed to leave without copious amounts of added horsepowers. Despite our constant sales-pitches, and relentless nagging, (usually heckling him while he was waiting in our lobby for us to finish routine maintenance on his car) Anthony’s car would depart time after time with a completely stock motor.

    For those of you who aren’t familiar with our origins, 034Motorsport’s history is deeply rooted in tinkering with Audi inline 5 cylinder engines, predominantly the formidable AAN I5 20VT found in the UrS4/S6. What started out as Javad’s personal project car – countless hours of work filled with blood, sweat, and tears – grew in a matter of years to become 034Motorsport, one of the leading Audi tuners in the world, specializing in the inline 5 cylinder.

    Something didn’t make sense. This was Anthony Marino, founder of Audizine, and driver of what is the cleanest UrS6 Avant we had ever seen. We were 034Motorsport, home of the highest horsepower AAN 5 cylinder engine on this side of the planet. At first glance, it seemed that the sun, the moon, and the stars had aligned, and fate had brought us both to the SF Bay Area. But his UrS6 remained stock as far as power was concerned, with the exception of an unknown chip-tune…

    Month after month, Anthony would swing by without giving in to any of our horsepower-filled goods. We began plotting… How can we get him into a bigger turbo? Should we bribe him? Drug him? Skip straight to torture? Luckily, we didn’t have to resort to any of those things.

    Very recently, Anthony came to his senses, and the modding began. To be precise, it started with our 3″ turboback exhaust system. We had to custom-fabricate the exhaust on his car, as our standard UrS4/S6 exhaust would be too long for his shorter Euro rear bumper. With the AAN’s newly unleashed exhaust sound emanating from his car, Anthony soon decided that some more power was in order.

    After some deliberation, Anthony decided on our K26/GT3071R Turbo Upgrade Kit, and our 034EFI Stage 1 Chip Tuning & Fueling Package for the K26/GT3071R. We also added our Bosch 044 Drop-In Fuel Pump Upgrade to the list for good measure, as the new turbo would require more fuel than the stock pump could deliver.

    Anthony’s UrS6 Avant spent the week with us at the 034Motorsport Automotive Luxury Resort, here in Fremont, CA.

    When the car arrived, we promptly did a baseline dyno, and realized that it was running dangerously lean, seeing 15:1 AFRs under load, and making about 220WHP. Upon removal of the ECU, we discovered something along the lines of “Billy-Joe’s Country-Fried Awwwwwdeeee Terbow Chip” scribbled onto the ECU in Sharpie… That explained quite a bit.

    Once the new parts were bolted on, we strapped the car back down on our Land and Sea AWD Dynamometer. We started with our off-the-shelf 034EFI Stage 1 K26/GT3071R Chip Tune, which we fine-tuned real-time on the dyno to be tailored specifically to Anthony’s setup. The car ended up making a whopping 369.4 horsepower and 359.2 ft-lbs of torque at all four wheels, all on a safe, reliable tune.

    Overall, we’re very pleased with how the car turned out. The new 034Motorsport hardware and tuning perfectly complement the exceptional condition that Anthony’s car is in. There’s still plenty of headroom left for more power with the addition of more parts, too, so stay tuned for updates!

    In all the excitement of working on Anthony’s Avant, we totally forgot to take pictures of the car… We went out for a quick 10 minute photo shoot (our camera’s battery died) earlier today when Anthony was on his way to pick up the car. Here are a few of the shots we got:



    A huge thanks to Anthony for letting us take care of his car! Hope you’re having fun with it!

    Concept To Reality – 034Motorsport Lightweight Flywheels

    February 20th, 2010

    Here at 034Motorsport, we like to see things through from start to finish whenever possible.

    We develop our Motronic tunes starting with a clean slate. We design and fabricate our exhaust components in-house. We test and validate the latest firmware revisions to our 034EFI ECUs on shop and employee cars.

    We don’t outsource our product development to other companies and then claim to have “engineered” the the parts.

    So, we’re sure you can appreciate why we stepped up to the plate by providing our own, unique, 100% 034Motorsport, Lightweight Aluminum Flywheels. These flywheels are designed, prototyped, tested, machined, and assembled all under one roof. Ours.

    034Motorsport flywheels are developed and validated utilizing state-of-the-art CAD software, then transferred to complete assemblies with ring gear, friction surface, and hardware. This method allows us to know how much the flywheels will weigh, and what they will look like, without wasting materials and machine time.

    CAD_034_B7_LWFW

    The assemblies are once again reviewed and validated, machining operations are defined by our engineer and machinist using CAD/CAM software, and the machining process begins.

    Each flywheel starts its life as a chunk of billet aluminum, which we mercilessly feed to one of our in-house Haas CNC machining centers. All of the fixtures we use for our CNC machined products are designed to ensure consistent fit and allow our parts to be machined to precise tolerances with every production run. Here is our Time Attack VR6T B5 A4 making friends with the Haas VF-3SS YT:

    VR6T_Haas

    Once machining is completed, the flywheel is weighed, hand assembled by our employees, and then weighed again.

    B7_LWFW

    For all new designs, the prototype flywheel is test fitted, and rigorously tested on 034Motorsport and/or employee vehicles before final release.

    Production flywheels are neatly placed into 034Motorsport packaging, and put on the shelf ready to ship.

    Being directly involved in our flywheel development from the early conceptional stages all the way to full-blown production allows us to provide unique solutions at a much lower price, all while meeting our highest quality standards.

    B5 Audi A4 1.8TQM – 2.0T GT2871R

    February 12th, 2010

    This is our latest B5 1.8T build that we completed this year, and it is definitely the most fun.

    This particular customer came to us with 1997 A4 1.8T that hadn’t run or been registered since 2001. The car had a chewed up disaster for a wiring harness, a cobbled together turbo kit with both internal and external wastegates, and had been through a few motors. In fact, he hadn’t even seen the car in 6 years when he shipped it down to us.

    He wanted a reliable, consistent, quick-spooling 350+ HP setup, without sinking too much money into the motor.

    Once we got started on the car, more and more of the old hardware had to get tossed out in favor of new, professionally engineered performance parts. It’s always easier to start with a clean slate, to say the least.

    After countless hours of replacing hackjob parts and removing rat nests, dead squirrels, and spiderwebs, the car was ready to hit the dyno for break-in and tuning. We even had it detailed when we were done. Here are some pictures, specs, and dynos from the completed project.

    Eurotuner GP 2009 – Bloopers

    January 23rd, 2010

    Here are some of our shenanigans and less-than-graceful moments from last year’s Eurotuner Grand Prix.

    Featuring:

    - Mike Rohrbach attempting to learn how to drive a stick, before giving up and deciding to drag race a 700HP E92 BMW M3 in our Ford F350 Powerstroke tow rig.

    - Christian Miller going on an off-road excursion in our Time Attack A4 VR6T after spotting an innocent bystander eating french fries.

    - Javad, Mike, and Christian perfecting poses that they learned from the “Icy Hot Stuntaz” in front of our ETGP entry. There was a lot of sagging, leaning, mean-mugging, and ball grabbing in hopes of getting “mad wiminz.”
