      Here we have a direct comparison between a 335 with the Cobb Tuning Accessport Stage 1 vs. a 335 with a JB3 2.0, Stett CAI, and Stett charge pipe. The JB3 car pulls but it is important to note it is RWD vs. an AWD car so not exactly apples to apples. Also, we assume this was pump fuel. Still, great to see a comparison like this. ...

      Many of us were attracted to German performance by BMW. There was a time when they made cars unlike anyone else. Cars that took no short cuts, with motors that represented the best their engineers had to offer. Now what do we have? Anti-tuning ecu's, the same motor in every car, M SUV's, FWD city cars coming, smaller and smaller motors paired with extreme brand dilution. ...

      Carmagazine is reporting that a Z2 Roadster with a soft top is confirmed for 2012. The downscaling of the BMW brand continues to sell as many cars to as many people as possible. The motor will be a new 1.6 liter turbo with around 200 horsepower. This likely will be a fun car to drive with a targeted 2200 pound curb weight and the rendering is interesting. They are also considering an electric version. Will get an M version of this as well? If we do, just expect it to be the same thing with more boost. More details as they come. ...

      Kelleners has recently gotten into producing body kits and wheels with their F10 entry. The rims are actually reasonably priced (for a European BMW tuner) at Ä397 and nice designs. No pictures of these mounted on any BMW yet. ...

      We still do not know what the internal designation for this motor is but we now know it is official and it is coming. The specs are 245 horsepower and 258 lb-ft of torque. This motor will first appear in the Xdrive28i when it comes on sale in the United States. The motor will be rated around 30 mph on the highway which improves considerable on the N52 it will be replacing. Compression is 10.0:1. More details to come shortly such as the designation, boost, redline, etc. ...

      This rendering of the F30 was done for Bimmer Magazine by Schulte Design. The E9X platform still has a couple good years left in it but it is on the downward swing. The F30 is coming and if it looks like this rendering that certainly is a good thing. 5 series headlight cues can be seen but we doubt the front bumper of the standard model will be anywhere near as aggressive. The N55 and the new 4 cylinder turbo motor should be the powerplants that launch with it mated to an 8 speed automatic. This is a good interpretation of the future model but we remind, it is just a rendering. ...

      People all around the world have fallen in love with the automobile since itís creation over 100 years ago. Entire lives have been dedicated and lost to our love for the automobile, and for the feeling that it can give. Anyone who wants to navigate the aftermarket performance industry must have a good understanding of the allure of the sports car and what itís meant to humans since its invention. Itís always easy to spot those in the business who do not have a genuine love for cars, as their misguided intentions will always reveal themselves in the way they create their own project cars. ...

      Score another victory for BMW Motorsport, the Z4 GT3 won by over 4 laps in the 24 hour race. The car was driven by ALMS driver Tommy Milner as well as Augusto Farfas, Claudia Hurtgen, and Edward Sandstrom. The Z4 controlled the race nearly from the beginning when the pole setting Reiter Gallardo was forced to retire due to engine trouble. The other Z4 GT3 which was the sister car run by Turner Motorsport finished in 5th despite several issues including an accident and a cracked header. Congratulations to the Schubert racing team and BMW!

      The BMW X1 is already available for sale around the globe. It was supposed to be available in the largest market for the SUV, the United States, in the beginning of this year. Strong demand has the factory in Europe at full capacity. Unlike the X3, X5, and X6 built in the United States the X1 is built in Germany likely because it has far more in common with the chassis of the regular cars instead of the SUV's. If sales continue to be strong, it may even be delayed further than the fall. ...

      Let's be realistic, the majority of aftermarket companies do not last. Many come and go likely before we even get a chance to hear about them. It is even more difficult for those that specialize in forced induction on BMW's. Boosting M motors and BMW NA motors in general has never been easy and few have been around as long as Active Autowerke. AA has been around since 1981 and is older than many of the people on this site including myself. Active has done some top builds that captivate the community such as TazaM3's custom E46 M3 turbo which is one of the most powerful BMW's in the world. We would like to congratulate Active Autowerke on 30 great years and state the BMW performance world is better thanks to their involvement. Here is to 30 more! ...

      Steve (M5junky) sent us these pictures with permission to post them. These pictures reveal the state his E60 M5 was in after having spent about 2 years at ASR Engineering. The car was sent there for a twin turbo built motor setup as most of you know and nothing was done. Well, nothing other than stripping the car the car down and leaving it a huge mess. The transmission was pulled and looks to be left stock. The motor was pulled and not built as agreed. The engine bay, well, you can see for yourself. ...

      As a lot of you know I live in Johannesburg South Africa which is 5500ft above sea level. Tuning of the car is a work in progress but I got a opportunity today to give the car a run on a dyno just to see where I am at with my "street" map. Runs where done with 93 and meth (CM10) and the temp was 30 degrees celsius with no cooling of the car. We have not touched the tuning much above 6000rpm as we had to make sure we had the fueling waxed at lower high torque rpms. Boost pressure was set at 19psi and tapered to 15psi at the higher rpm. The timing is also very conservative and I am confident to say that we can push 475whp in race trim comfortably. So far Chip Logic does not seem to have hit any barriers in the tuning of larger turbos using flash software. ...
