    The BMW M3/M3 and Porsche 911 have quite a bit in common this generation. Why? Because both have twin turbocharged and direct injected 3.0 liter six-cylinder powerplants. You can also get either with a dual clutch or manual transmission with power sent to the rear wheels. Let's look over the specifications of the motors: 9A2 3.0 991.2 Carrera Horsepower: 370 Torque: 332 lb-ft Boost Pressure: 13.1 psi Bore x Stroke: 91mm x 76.4mm Redline: 7500 rpm Compression Ratio: 10.0:1 Intercooler: Air to Air Turbos: 49mm compressor/45mm turbine Piston Speed FPM: 3759.842 BMW S55 Horsepower: 425 Torque: 406 lb-ft Boost Pressure: 18.1 psi Bore x Stroke: 84.0mm x 89.6mm Redline: 7500 rpm Compression Ratio: 10.2:1 Intercooler: Water to Air Turbos: 51mm compressor/43mm turbine Piston Speed FPM: 4409.449 Obviously, we all know the S55 engine is highly underrated by BMW. Recently, when Porscheboost was doing some testing at VF-Engineering on their Mustang dyno the opportunity presented itself to overlay a stock S55 with the stock PorscheBoost project 991.2. Here is the result, both dual clutch examples stock on 91 octane pump fuel: What is interesting to note is that the spool on the 991.2 Carrera 9A2 is much better than the BMW S55. The Carrera is spooled by 2400 rpm and the S55 has more lag by roughly 1000 rpm. That is significant. You will notice once spooled the curves are fairly similar. The S55 does have more peak torque and horsepower but the difference is not as large as one would expect. The difference in torque is only 3 lb-ft at the wheels. A wash. Not bad for what on paper is supposed to be 74 lb-ft. The 911 is making more torque than Porsche is letting on by quite a bit. The difference in peak horsepower is 15 at the wheels. This is attributed to the S55 making power to 6850 rpm while the 9A2 is tailing off past 6400 rpm. Both torque curves are dropping hard but the S55 maintains a top end edge from 6400-6800 rpm. Revving either engine out to their 7500 rpm redline does not gain anything and short shifting is preferred for maximum performance. It is interesting that the 9A2 engine with less boost and slightly lower compression is so close. It is also interesting the spool is so much better but Porsche likely concentrated very hard on quick spool down low to appease naturally aspirated purists who would complain about lag. The engine comes on strongly and quickly. It is no wonder the 9A2 knocked out the S55 in its category at the 2016 International Engine of the Year Awards. In an ideal world we would be able to toss a Carrera S and a GTS onto this dyno to see how Porsche is really separating their 9A2 motors. We do have Dynojet numbers posted for the Carrera and S but the GTS is the variant we are all eagerly awaiting to see. This is the difference between the turbocharged 991.2 Carrera S 3.0 and the naturally aspirated 991.1 Carrera 3.4: BMW of course has the Competition Package version of the S55 and now the CS version in an even higher state of tune essentially doing what Porsche does in offering the same motor in different flavors. The main difference though is that Porsche changes the turbochargers and not just the software offering greater differentiation and tuning value in this respect. What is clear is that the turbo era is elevating power and torque to heights we have never seen and it will result in a far greater proliferation of tuning for Porsche and BMW models than ever before.

    BimmerBoost member pits200 has an automatic BMW 335xi with the VTT GC N54 turbocharger upgrade. The car has 115k miles on it and has not exactly been babied as it has been tuned for over 100k miles at this point. This is important to point out as the GC upgrade is obviously making big torque but his trans is holding the power at 26 psi of boost. It is running well as the drag race video below will testify to. He knows the transmission is on borrowed time but so far with a TCU flash it's holding together and not slipping. You can read his build thread here if you like.

    Hi, So I had a tail light out and inspection is around the corner. I was curious as to how much it would be and the service advisor quoted $350. I searched and found someone who had success with replacing the Valeo board with a mean-well LED driver. The part is LDD-500HW. You can choose which ever method of connection you prefer but i ordered the one with wires. I ordered 2 for about $20 total after shipping. You can find them here: http://www.ledsupply.com/ or here https://power.sager.com/ldd-500hw-2719565.html See attached photos as it was pretty simple. Take the tail light off, remove the connections, and attach the new led driver with a no solder method. I am sure I could dig deeper and find the connector mate to the valeo board so there is an actual plug and play, but I didn't do it because it is already late at night.

    Careful, the quote you are about to read is drenched in estrogen. "The 840-hp Dodge Challenger SRT Demon from Fiat Chrysler is so inherently dangerous to the common safety of motorists that its registration as a road-worthy automobile should be banned." Somehow the hyperbole being spewn seems to be much more dangerous especially to common sense. If we really want to get down to what is safe for our roads more people will be killed or injured by senior drivers than those with a Demon. Frankly, no Demons are even on the road so how is the author coming to the conclusion that the car needs to be kept off public roads for safety reasons? Well, because the premature and negative conclusion fits the narrative. This is one of those same people that sees a gun and automatically classifies it as an assault rifle based on the appearance and not the application. You know what the world needs? More Dodge Demons. More manufacturers that take enthusiasts into account. More cars that are fun to drive and less vehicles that are tuning into appliances that remove the driver from the equation. What does this person think is going to happen? A Demon on the road is just going to suddenly start driving into people? Owners will be drag racing across crowded parking lots? A teenager in a Honda who just got out of seeing a Fast and the Furious movie is more dangerous on the road than an adult behind the wheel of a performance car they paid for and are familiar with. The Demon is no more dangerous sitting in traffic than any other car. A 5700+ pound sport utility vehicle crammed with luggage and passengers traveling over the speed limit on the highway that physics simply will not allow to stop in the same distance as a lighter car is a much more dangerous proposition than the Demon. Truckers who have not slept for who knows how long hauling tons of goods on the highway across the country are a much more dangerous proposition than the Demon. If anything, the Demon is safer than the standard Hellcat. It is built for traction off the line which means you can get into trouble a lot easier with tire spin on the standard Hellcat. The tires offer more grip, not less. How is the Demon a result of misguided corporate choices? It is built to be the quickest production vehicle in the 1/4 mile and achieves that goal. It does so on an NHRA dragstrip, not the street. Did someone forget those exist? A place where you can take your car and run as fast as you want to without endangering the public? The Demon is the result of incredible engineering, development, and effort. Dodge did not randomly roll some dice and end up with the Demon. What they accomplished for the money has never been achieved. This kind of fear mongering is an enemy to the entire automotive world: It is not banned for being too fast. The NHRA requires a roll cage for cars that are quicker and faster than set limits. If the Demon is 'too fast' so are a host of other street legal cars. All that is necessary to get them into compliance is a roll cage you hack. It is not the Demon that needs to be removed. It is this garbage from Automotive News. The author did not even have the courage to put their name on it. That tells you what the purpose of it actually is. Source

    The C7 Audi RS6 is not sold in the USA which we may never forgive Audi for. Not everyone needs or wants an SUV and a performance wagon makes a lot of sense. Ok, enough whining about Audi, how does the RS6 stack up to a Nissan GTR? The GTR is not light but in this company is the much lighter car by roughly 900 pounds. They are both all wheel drive but the GTR uses a dual clutch transmission compared to the more traditional automatic of the Audi. The RS6 obviously has the 4.0 liter turbocharged Audi V8 and the GTR has a slightly smaller VR38DETT V6. So which is quicker? The RS6. Unfortunately, no data is provided and it looks to be a rather short drag race. Did the GTR even do a full launch? The GTR should be favored based on test results and the weight advantage compared to the RS6. Without any supporting data, it just looks like this video was put together for clicks by providing a controversial result.

    This drag race features some impressive hardware. Unfortunately, it is designed more for promotion than performance results but that's ok. Just getting these ten cars together and having them all race at once is very cool and obviously a great way to get views. Every car is tuned by German tuner Levella. The cars have their ECU tunes along with the Levella wheels. The cars look great but as you can see with the tires going up in smoke these wheel and tire setups are for looks and not performance. That means the all wheel drive cars are favored. The Nissan GTR takes it. It is followed by the Aventador, 991 Turbo S, Huracan, and Audi RS6. Yep, all wheel drive cars. There isn't any timing equipment employed but still fun to see so many tuned examples go at it.

    Naturally aspirated AMG V8 against the BMW's 3.0 liter twin turbo I6. Both motors benefit greatly from tuning as we all know. The W204 C63 AMG is heavier than the 335xi by roughly 500 pounds but 6.2 liters of displacement helps move it. It also has the P31 package which means stronger engine internals borrowed from the M159 and a more aggressive factory tune. The 335xi is a manual example with an MHD Stage 2 flash. Nothing is stated about any other bolt on modifications. They start with a dig race and how it should play out is the 335xi should get a lead with the M156 top end then coming into play. That is exactly how it goes. That means in the next race when they go from a roll the C63 should have the advantage once traction is removed from the equation. That it does, it pulls a couple cars. They do another dig race and the 335xi gets out in front only for the C63 to make up the ground and pass again up top. Solid runs all around.
