    There is a lot of tuning talk about the new Audi TT-RS and Audi RS3 models with the updated 2.5 TFSI dual fuel injected I5 turbo motor. Recently, the MKIII Audi TT-RS broke into the 10's in the 1/4 mile tune only. This begged the question, where is the biggest name in Audi tuning and what are they doing on the platform? Well, APR is going about their development in their usual in-depth fashion. They have access to the Bosch MED17.1.62 ECU and software. They just are not releasing their dyno numbers just yet: It sure looks like they are getting some big gains there though despite the redacted peak figures. Audi changed a few things on the motor and there are many more sensors. APR is testing and collecting data before any releases. They are just being thorough. What we already know is that @Arin@APR confirmed the 2.5 TFSI turbo kit APR already developed that made over 600 horsepower to the wheels will fit without issue. As for upgraded internals, pistons and rods may need to be revised so no confirmation yet on whether APR's previous 2.5 TFSI forged hardware will work. They also have an upgraded intercooler in development as well: One can expect things to move pretty quickly. APR will release their software once testing is done with all their data. Then, you can expect the Stage 2 software for the intercooler and other bolt ons. The upgraded turbo kit should not take much time at all beyond software and some adaptations. The real question is, how far will APR push the motor? With fueling not being a big restriction the sky is the limit here. The 2.5 TFSI found in the brand new TTRS and facelifted RS3 sedan is a totally new 5-cylinder engine from Audi including an all new version of Bosch’s MED17.1.62 engine management system. The engine differs from other 5 cylinders in the past, using a brand new turbo, with a new control strategy, new dual injection system and new engine block material among other changes. We’re in uncharted territories tuning this new amazing platform! With any new project that vastly differs from others in the past, our engineers take a cautious and thorough approach to tuning the engine. This starts with data collection. Our APR ECU Explorer logging tool give us direct access to the entire ECU. That means we can read every sensor within the engine bay, and every single calculation taking place within the ECU, at extremely high data rates. This data resolution is second to none, leaving our tuners with the ability to see everything as it happens, with the ability to trace back to why it happened within the ECU. This allows our engineers to understand the ECU algorithms and strategies better than the competition. This is contrary to others relying on OBDII diagnostic channels, which gives poor and limited data used for general diagnostics, not tuning. However, even with this powerful tool, it’s not enough. When Audi tuned this engine, they did so with many more sensors installed, which they later removed and modeled into the ECU. By doing so, they saved money and can deliver a system that is modeled very accurately given the original operating parameters. With sensors removed, the engine management system predicts/models mass flow, pressures, temperatures and other measurements at various places within the engine system by basing those outputs on their relationships with other measured values. However, once you begin tuning the ECU, or changing hardware, these models are no longer very accurate! We need to add those sensors back during the tuning process to correct the incorrect/broken models, and provide a top tier ECU calibration. Our R&D team has installed a MoteC C125 Dash with various high resolution, and high data rate sensors all around the engine to collect critical data for our engineering team. This includes, but is not limited to Race-grade thermocouples and pressure sensors before and after the intercooler and at various places in the intake system to locate restrictions. We’ve also added exhaust manifold pressure sensors and exhaust gas thermocouples to the turbocharger to ensure our calibrations are well within critical engine limitations (shaft speed, EMAP, EGT, surge region operation, lambda sensor pressure and temperature compensation). With MoteC’s i2Pro software, we’re able to analyze and deliver critical data to our calibration and hardware teams create better calibrations and create new hardware products. With the guess work eliminated, we’re able to deliver a better product. Hardware

    Unfortunately, there are a good number of tuners out there that will lie, cheat, and steal. Claiming dynographs that actually come from others or editing graphs is something lesser known tuners do to try and elevate their profile. This is something BimmerBoost covered before. TRM Tuning or TRM BMW Performance Engineering is the latest tuner caught red handed attempting to pass off someone else's graph as their own. The claim is that this is a 1256 wheel horsepower BMW M52 tuned by TRM with their parts and a 'big turbo' as he calls it. The problem? This is a Supra graph from Induction Performance: TRM literally just edited out where it says Induction Performance on the original graph and cut off the power and torque curves past 7k rpm. They changed the peak torque figure by borrowing the 2 and the 5 from the HP figure to 972.25 from 971.89 in the original. Peak HP was changed from 1256.61 to 1256.12. Amateur hour work that anyone with Windows and MS Paint can do. Why didn't they think of changing the runfile number at the very least so it would not be such a blatant copy? Michael McCoy of TRM continues on with his BS: When in doubt, ask for runfiles. Additionally, if a tuner is willing to lie about their work and steal from others there are likely many other things they would be willing to lie about. Buyer beware.

    The direct injected 991.1 Turbo model broke into the 8's in the 1/4 mile. Esmotor is the first to achieve the feat on the 991 platform. For contextual purposes, the quickest US 991.1 Turbo runs a 9.70 @ 141 miles per hour. It is not surprisingly Esmotor is running this sort of time as the car makes 1073 horsepower to the wheels. As stated in the article on the topic yesterday, this is the first 991.1 Turbo to clear the 1000 whp mark. As for the modifications the turbochargers are Garrett GTX35's and the engine is fueled with six additional injectors controlled by a Syvecs standalone ECU. The PDK transmission is built by Dodson and the engine internals were done by Esmotor. Congratulations to @Emre@Esmotor

    You should know this W212 E63 AMG well by now. It belongs to BenzBoost member @Vasily1 and was built by GAD Motors. They essentially refer to it as Stage VIP. Why? Because if you have to ask you probably can't afford it. Back in August the car ran 10.0 @ 143.38 in the 1/4 mile at a Russian event. No, not on a dragstrip but there is no doubting that this is likely the quickest and fastest W212 in existence as nobody has proven otherwise. What does that kind of acceleration look like? Well, @Vasily1 posted a video his E63 going from 0-300 kph. The car makes the sprint absolutely effortless. This is an incredibly fast AMG:

    Back in the beginning of the year BimmerBoost wrote about Awron's E63 M6 drift car which received an S63 4.4 liter twin turbo V8 swap. Awron's engine management electronics make the swap possible and make for a very unique E63 M6. Not to mention one with a ton of torque. What do you do with all that torque? Spin tires and go sideways naturally. Check out the finished product doing exactly that in the video below with some incredible drifting and side by side action to boot. Just an incredible project and machine.

    A few days ago BoostAddict posted some GPS acceleration results for the Kia Stinger 3.3 liter turbo V6. Well, Car and Driver got their hands on the car and their numbers are not quite as impressive. Their 1/4 mile sprint is half a second slower with a 13.2 @ 108. Not to mention the curb weight figure. The Kia Stinger is heavy! 4157 pounds to be exact. All wheel drive is nice but wow does it come with a penalty. The Stinger is carrying similar weight to a BMW M5. Car and Driver feels the handling is a bit floaty. They also complained about the throttle and the transmission being slow to respond to commands. Overall the praised the value but stated the German competition is more fun to drive. For the $52,595 tested price it seems KIA comes up a bit short in driving dynamics. VEHICLE TYPE: front-engine, all-wheel-drive, 5-passenger, 4-door hatchback PRICE AS TESTED (MFR'S EST): $52,595 (base price: $39,895) ENGINE TYPE: twin-turbocharged and intercooled DOHC 24-valve V-6, aluminum block and heads, direct fuel injection DISPLACEMENT: 204 cu in, 3342 cc POWER: 365 hp @ 6000 rpm TORQUE: 376 lb-ft @ 1300 rpm TRANSMISSION: 8-speed automatic with manual shifting mode DIMENSIONS: WHEELBASE: 114.4 in LENGTH: 190.2 in WIDTH: 73.6 in HEIGHT: 55.1 in PASSENGER VOLUME: 96 cu ft CARGO VOLUME: 23 cu ft CURB WEIGHT: 4157 lb C/D TEST RESULTS: Zero to 60 mph: 4.6 sec Zero to 100 mph: 11.3 sec Zero to 130 mph: 19.9 sec Zero to 150 mph: 30.5 sec Rolling start, 5-60 mph: 5.3 sec Top gear, 30-50 mph: 2.6 sec Top gear, 50-70 mph: 3.4 sec Standing ¼-mile: 13.2 sec @ 108 mph Top speed (governor limited, mfr's claim): 167 mph Braking, 70-0 mph: 164 ft Roadholding, 300-ft-dia skidpad: 0.91 g C/D FUEL ECONOMY: 75-mph highway driving: 26 mpg Highway range: 410 miles EPA FUEL ECONOMY (C/D EST): Combined/city/highway: 20/17/26 mpg

    how did i miss this beauty of a thread? Just love how Tesla owners are always guzzling the koolaid fed to them by elon. I dont think there is any other car owner out there that tries to justify themselves more than tesla owners.

    Then why buy a tesla if you are just a soccer mom? A prius will do the same thing. Tesla owners and Tesla Fanboys try to promote Tesla as the end all be all to automobiles. And if you talk to one about the P100D and ludicrous mode, they will do whatever they can to convince you it is the fastest car out there; faster than the super and hyper cars. All this is was trying to do is the truth, and piss off the fanboys. And it looks like its doing a great job of pissing off the Tesla Fanboys.

    Always drove to Vegas from SoCal. Leave late Friday night, drive back late Sun night. Became almost an every weekend thing in college. Dealing with airport BS for such a short flight, no thanks. Plus I liked to have my car while there.
