    The E30 M3 released in 1985 was designed with DTM (Deutsche Tourenwagen Masters or German Touring Car) racing in mind. The S14 four-cylinder under the hood was designed for professional racing (as M3 engines traditionally have been) where it excelled. The S55 turbo 3.0 liter inline-6 in today's M3 is obviously a much more powerful motor. It is larger than the 2.0-2.5 liter S14 four-cylinder and also turbocharged whereas the S14 is naturally aspirated. The difference on paper is close to 100 horsepower but in practice it is closer to 200 horses as the new M3 is severely underrated. Horsepower is only one part of this story as the E30 M3 DTM car is much lighter and stripped out for the track. The weight difference is in the 1000 pound range based on a 3562 pound curb weight for the F80 M3. Can a chassis design that is over three decades old now compete with a brand new and much more powerful M3? Yes. Not only does the 1992 E30 M3 DTM car compete with the 2015 F80 M3, it beats it around the track. Keep in mind that back in the 80's and early 90's DTM cars actually represented their production counterparts. The E30 M3 does a 1:09.1 laptime around the Hockenheim to the F80 M3 1:13.1. A four second difference which is simply stunning. The new F80 M3 is a great car but it hardly makes the classic M's obsolete. Namely on the racetrack which the BMW Motorsport division used to design their M3's for.

    We've got the Vargas Stage2 N55 turbo running on our 2011 135i DCT car and was finally able to hit up the dyno for a little tuning today. The vehicle is FBO but equipped with a CPE replacement catted DP. We've recently modified both the E series N55 ISO JB4 firmware for large turbo support and developed an entirely new back end flash. To enable the JB4 large turbo maps you just enable the 3.5 bar TMAP sensor using version 5.5 or later. This changes map 1 to 16psi, map 2 to 19psi, and methanol mapping as high as your turbo will take you. All with reduced taper to redline to let the larger turbo shine. Dyno testing was done on simulated 93 octane (91 + 1 can of NOS octane booster), and the methanol testing was done with a single CM10 nozzle. Overall very pleased with the results especially for an odor free vehicle. The pump map is a touch aggressive but really showcases what the turbo can do. On pump gas I think the car would come very close if not take our F80 M3 if the M3 is running the stock tuning. And on meth would come very close to the M3 on the E30 map.

    In general, since we are all automotive enthusiasts here, I imagine we are all pretty good drivers. Sadly, that just means we are in the minority. I try to rarely complain, but I finally had to put together a list of my biggest frustrations while driving :angry-banghead: Agree? Disagree? Other additions? -Rich In priority order: 1. People who lolligag in the lefthand lane. After you pass, get back over. 2. People who don't secure their loads. See exhibit A. 3. Not understanding the proper way to merge. This includes both merging on to the highway, but also merging when lanes end say for construction. 4. Not passing a police officer/highway patrolman. It never ceases to amaze me the number of people who refuse to pass a highway patrolman, even when the officer is cruising well under the speed limit. I have to imagine this is some sort of game/stress reliever for POs - let's see how slow we can go without people passing us. :facepalm 5. Not turning right on red. I realize this isn't legal everywhere, but for the areas it is, for the love of God, turn when the coast is clear. 6. Tailgating. I hate tailgaters. 7. Rubber necking at accidents. Move along folks. Nothing to see here.

    Well that was pretty fast. As reported last week the M3 / M4 S55 engine control unit has been cracked. Keep in mind this is very early in the flash tuning process of the new M3 and M4 but there are multiple tuners with the ability to flash the ECU out there with many more to come. Jailbreak Tuning posted the first Dynojet results of their flash tune and the result on 91 octane pump fuel is an increase of 20 peak horsepower at the wheels. Obviously peak horsepower does not tell the whole story especially on the newer BMW turbo motors as the gains in the mid-range are in the 50 wheel horsepower range. The torque curve is much fatter and the peak torque figure increases by 42 lb-ft at the wheels. People will obviously being comparing these flash figures to the BMS piggyback tune figures. As of today, piggyback tuning shows greater horsepower and torque gains. It will be interesting to see how these two approaches play out and the way they play out will likely be reminiscent of the N54 tuning scene in which each approach has its place with many people using both for the optimum setup. Regardless, the flash tuning era of the S55 inline-6 motor is officially underway.

    Sorry to put a damper on the parade but the flash tuning capability of the new turbo M models is greatly overstated. A couple of days ago results were posted of a flash tuned S55 inline-6 which is the turbocharged M motor featured under the hood of the F80 M3 and F82 M4. It is true that this car was flashed but after seeing the article BimmerBoost was contacted by a tuner who wanted to set the record straight on what is actually going on. Nobody at the moment has real control of any modern ECU used in the turbo BMW's. This includes the F30 models, F10, F12/F13, F82, F80, and so on. The tricore ECU's in these cars have not been cracked. So what exactly is going on? The tuners claiming the ability to flash are all using the same trick but they are not uploading their own custom tuned software. They are essentially flashing the same files that originate internally from BMW. Some of these files are just press files. Oh, you did not know BMW uses different software on cars they let the press test? Well, namely with the F10 M5 and F12/F13 M6 they do. Why? The BMW press software will allow a higher margin for a CEL (check engine light). That means you will not see any of those nasty reviews saying the cars went into limp mode. This among other things like traction control changes or higher boost itself. Some tuners have even been using the BMW Competition Package software which is not real flash tuning. It is just uploading BMW's own file. If anyone needs proof of this ask for a custom dyno tune for your F10 M5 or F80 M3. It is not going to happen, at least not yet. Tuners can play with the bootloader but if they modify outside of certain parameters the checksum fails. If it fails, the software will not flash. All of the big boys are struggling with this believe it or not. Dimsport which is traditionally the source for a lot of automotive ECU cracks that then spread out (for $ from others) can not flash tune the Tricore ECU's. Some guys may be using this Russian software for the Tricore ECU's to read out of the files but what can they do with it once they do? The tuner that contacted BimmerBoost said to ask the tuners for proof of their ability. No tuner that has contacted BimmerBoost stating they have the ability to flash tune has demonstrated it. So how do you get a dyno graph showing gains with a flash tune? Well, you can run a car until it is hot and then flash BMW's own software that leaked out and once the car cools down showing gains with a handpicked before and after graph. BimmerBoost stands by this report that nobody has true flash tuning ability at the moment. BimmerBoost will also state that many tuners make their living simply flashing factory files from Europe over on US cars at a markup. We will not name who it is that predominantly does this but the readers here are smart enough to figure it out. The flash tuning era of the F80 M3 / F82 M4 and F10 M5 / F13 M6 can not even be stated as being in its infancy as the development is not even that far along. We will see what happens but internal sources at BMW that traditionally have helped can not. You would not either if it meant losing your job.

    Great runs here courtesy of BenzBoost member Vasily1. We have seen his E63 AMG in action before. As a reminder, he has a prototype Renntech E63 AMG 4Matic M157 turbocharger upgrade on his car which is putting out something in the 850 horsepower range. We have seen some impressive performance from this car including runs with a Lamborghini Aventador as well as a supercharged C63 AMG and another tuned GTR. In this run video @Vasily1 takes on a PP-Performance Stage 2 tuned F13 M6 said to making 740 horsepower. In addition, a Nissan GTR with a quoted 700 horsepower is also in the mix. Thanks to multiple angles and good video quality we get a new view of the action. The M6 and GTR both put up a good fight. The E63 AMG S is the fastest of the trio though consistently managing to open up a gap between it and the other two cars up top. The only run the E63 loses is the very first one where the GTR gets the better start on it but the E63 starts reeling it in. As the other two cars are on stock turbochargers the power and torque advantage here clearly lies with the E63 AMG and it shows. That stated, the GTR and M6 do well against stout competition.

    Liter plus bikes are pretty damn fast, we know that. Power to weight tends to favor bikes at least stock. This bike is not stock however and is turbocharged putting out 425 horsepower at the wheels on C16. It is basically similar to riding a cruise missile. UGR (Underground Racing) makes some spectacularly fast cars with some of their twin turbo V10 Gallardo's and R8's rumored to be putting out well over the 2000 horsepower mark depending on who you ask. This Gallardo is stated to have '1750' horsepower. Based on a quick power to weight calculation it has around 1.94 pounds per horse. The Hayabusa based on a 425 wheel horsepower number and a ~600 pound weight with fluids and the turbo has 1.41 pounds per horse. The aerodynamics of course favor the Gallardo. So what happens? The Gallardo wins. Why? Well aerodynamics from a roll as stated and probably because it has more power than is being let on. Taking down a Hayabusa on the highway in a car is an incredible feat. A turbo Hayabusa? Well, that requires something truly spectacular. That is exactly what this UGR built Gallardo is.

    Big news here from Weistec Engineering who has managed to keep their Mercedes-Benz McLaren SLR twin turbocharger development under wraps until now. The Mercedes-Benz McLaren SLR as you know has an M155K supercharged 5.5 liter AMG V8 which is based on the M113K supercharged 5.5 liter V8 familiar to us from the W211 generation E55 AMG. Weistec decided to remove the supercharger on the SLR and add a pair of turbochargers in. The Weistec SLR Biturbo system is still under development so few details will be shared at this time. What we can tell you is it will be officially released later this year. Additionally, Weistec will have M155K V8 built motor options with forged internals for those that want big boost. The system will be sold as a package. As far as power figures expect some eye opening numbers when the time comes. The Weistec SLR McLaren Biturbo System is the pinnacle of SLR performance. Cast Inconel manifolds flank the 5.5L V8, supplying ball bearing turbochargers and external waste gates with high flowing exhaust gases. These gases are then routed via 304 stainless steel downpipes, paired with aerospace grade bellows, and connect to the mufflers. The biturboís forced air charge is tri-cooled via an additional intercooler and cooling circuit working in conjunction with the factory intercoolers, allowing for high performance and consistency in any climate. Official Release Fall 2014

    The Active Autowerke Level III supercharged M3's continues to impress. This particular M3 runs a full bolt on Cobb tuned Nissan GTR on the highway. The GTR has the Cobb tune, downpipes, a full exhaust system, intake work, and is on 93 octane pump gas. The M3 features the Active Autowerke Gen 2 Level III S65 v8 supercharger system along with a full exhaust setup. It is not stated whether it is on pump gas or race gas for this run. A full bolt on GTR with a tune is a very potent weapon. However, a roll on race between the two cars on the highway assuming similar power should favor the M3. Why? Because it is rear wheel drive, revs higher, and lighter. A run from a stop favors the GTR with its all wheel drive traction and torque advantage. As both cars have a dual clutch transmission that particular area is even. The M3 pulls surprisingly quickly but it also looks to get a jump on the 'two' count. Regardless, it continues its pull. It would be great to see a rematch between these two cars with the GTR on a race gas map.

    Good news for owners of the new Volkswagen and Audi EA888 2.0 turbo motor. APR has released their tuning software for the engine which covers the 2014 up Audi A3 2.0 and the 2014 on MKVII Volkswagen Golf GTI. The software is flashed through the OBD-II port and has programs for 91 octane, 93 octane, and 100+ octane race gas. APR also bumps the redline up to 7100 rpm from the stock 6800 rpm. So what are the gains? The baseline on a MKVII GTI is 210 horsepower at the wheels. On 91 octane with the APR tune this rises to 281 horsepower on the wheels. 93 octane boosts power further with the APR tune taking the car to 291 wheel horsepower. The race gas figure is 303 wheel horsepower. APR did not take the tuned car to the drag strip but did some VBOX performance meter testing. Their 93 octane VBOX trap speed is 97.19 miles per hour. The trap rises to 110 miles per hour with the Stage I tune on 93 octane. This figure will be lower on an actual drag strip as the VBOX tends to read higher. Dynographs and an acceleration video below. Solid work as always from APR. 91 Octane: 93 Octane: Race Gas: Stock vs. tuned acceleration numbers and overlay video:

    Just hurtin some feelings in Newburgh last night. 2nd run is an 04 ZX 10 (not GSXR). We ran that '73 TT Camaro(76mm turbos,20psi,1500whp,C16,3600lbs) 2 weeks ago for $3k and they wanted a rematch. Stock motor '14 ZX10,pipe/tune/lowered/rider mod I tried to run the Supra,he wouldn't run my turbo bike so he set a run up with my friend instead Enjoy

    Audi showed off a triple turbocharged 3.0 liter V6 diesel motor in May of this year on the RS5 TDI concept. That engine concept is moving to reality as Audi confirmed that the engine will see production in the upcoming SQ7 TDI. What type of output the SQ7 TDI will have nobody except Audi knows at this point. In the RS5 TDI concept Audi tuned the motor to 385 horsepower and an eye opening 553 lb-ft of torque. AudiBoost has its fingers crossed the production variant of the motor approaches this output. People refer to this electric compressor as a 'turbo' and that includes Audi themselves. However, an electrically driven compressor wheel is essentially an electric supercharger. The advantage is that you do not have to wait for spool from exhaust gases but that the wheel with electricity can be spun to maximum right off idle. The idea is to eliminate lag from the turbochargers which is vital in low revving diesel applications. The electric compressor helps throttle response and off the line performance. Once the conventional turbos are spooled the electric 'turbo' is disengaged and bypassed. The question remains on how Audi intends to power the 9 horsepower electric motor spinning the wheel and where that energy will be stored. The engineers will sort all of that out. The diagrams below help explain how the idea works. Source

    This is a rumor that just won't die and even BMW themselves just does not seem to know what side of it they are on. Just last year BMW stated an M version of the new i8 hybrid does not make sense and the 'i' and 'M' brands simply can not mix. Frankly, BimmerBoost believes that BMW 'i' could use a little BMW 'M' sprinkled on it. The base that makes the most sense for the M brand to use to produce an i9 supercar is the i8 unless an entirely new platform is created. The Germans over at Auto Motor Und Sport state the i9 is an i8 on steroids. Instead of using a three-cylinder motor that barely offers enough power for a lawnmower the i9 will get BMW turbo inline-6 power. Which inline-6 will they use? Hopefully the underrated S55 turbocharged 3.0 liter inline-6 from the new M3/M4. Additionally, more juice is expected from the electric motors. That likely means heavier batteries and the larger motor itself would be heavier so yes, the i9 would weigh a bit more than the 3380 pounds of the i8. Probably somewhere over the 3500 pound mark which with close to 600 horses and all wheel drive is absolutely fine. Now, this all sounds great but the real question is will it happen? M stated they want to build a supercar. Some idiot at BMW headquarters said BMW 'i' and 'M' can not mix because he is an idiot and apparently differentiating between two different letters of the alphabet confuses him. A BMW i9 with some serious power to back up the looks is the perfect way for BMW to celebrate 100 years. There is no official word on if it will happen but let's hope the Germans are not just making this report for hits. BMW, you owe us one. Just give us one freaking car that shows what you can do. 100 years is the perfect excuse to use against whatever accountant says it is too big of an expense to justify. Build the car, show the world just how good you are (were), and fire any accountant or executive against it. There should not be an internal debate on whether an Ultimate Driving Machine should be built. Do it. Source

    Audi and Porsche do not really like each other. They have to play nice as Volkswagen owns both of them now but Porsche and Audi each want to call the shots in the luxury segment. As Porsche expands its model lineup it continues to step on Audi's toes. Audi does not like this but Porsche also does not like that Audi made the R8 which definitely targets potential 911 buyers. Each company is taking offense with the other. This in-house battle is increasing as Porsche and Audi both are dumping money into competing platforms. Rather than cooperating each wants to push their own platform. Porsche wants Audi to use its platform for the next generation Panamera for example. Audi wants Porsche to use its platform developed for the next generation Q7 to underpin the Cayenne but Porsche is saying the platform has to many deficiencies including limitations with engine choices. Volkswagen wants everyone in the VW Group to use Audi's design to save costs. Lamborghini apparently is not too happy with Porsche as VW apparently is having Porsche design all the future sports cars in the VW Group. Lamborghini does not like what Porsche has planned for the Huracan successor. Audi who uses the Lamborghini platform for the R8 is also not happy with Porsche's approach so Lamborghini and Audi appear aligned against Porsche. Bentley on the other hand is happy with Porsche and their MSB luxury platform they intend to make use of. Lamborghini wants its own chassis and one designed to accept V10 engines. Porsche is building a chassis around their flat-6 motors which obviously benefits them. Audi uses the Lamborghini V10 so they are with Lamborghini on this one. See the mess? This is what a senior Volkswagen source stated on the matter, "If we donít call the shots here at HQ, Audi and Porsche will never get their acts together. What these guys fail to understand is that they have to cooperate, not fight each other. We need to prevent individual sports car architectures and excessive proliferation, and to make Porscheís MSB mandatory for both brands. Standardize the stuff that is really expensive: drivetrains, electronics, alternative propulsion systems, batteries, materials, methods, and processes. Audi and Porsche must stop fighting over architectures and concentrate on diversification by content. Itís as simple as that. And as difficult.Ē This is a bit of a mess but when so many brands are added into the mix and have overlap it is simply a matter of time before people butt heads. If VW wants to prevent this getting messy they need their executives to step in and dictate who will use what platform. That or they can let the brands compete against each other. Who really wants the same SUV rebadged seven times? It is going to be interesting to see what happens and how this is resolved. Source
