      Well, here it is, an E46 M3 in the 10's in the United States. To note, an E46 in Sweden did run 10.71 but that was not a strip with NHRA approved timing equipment. Regardless, this is the first true 10 second M3 in the USA with a 10.89@141. Tuning was handled by ProEFI and the hardware was built by Saad Racing. This breaks the record HPF held but we expect this record to be retaken by HPF shortly. Of note, this is a full interior street car. ...

      Here is Hamann's widebody F10 M5 body kit. In addition to the body work, Hamann claims to have tuned the car to 720 horsepower. We hate when Hamann releases these claimed numbers without dyno graphs or acceleration numbers to back them up. Hey, they are a big name and can get away with it but this kind of thing would never fly with US tuners. The widebody itself is not bad but they of course had to go and throw LED's in the front bumper which kind of cheapen the image of the car. ...

      Well just as the N20 powered 328i is right on the E36 M3's heels the N55 335i is right on the E46 M3's heels. Motortrend hit 13.3@103.9 in the 1/4 mile which certainly is respectable. It does not really offer much of anything on the previous N54 powered 335's and is not as good of a tuner platform right now but hopefully that changes. BMW continues to rate the motor at 300 horsepower in the F30 so the underrating trend continues. ...

      COBB Tuning is proud to announce the release of AccessTUNER Pro tuning software for AccessPORT equipped BMW N54-powered vehicles. The AccessPORT is the only hand-held OEM ECU flashing, managing and monitoring device available for N54 equipped BMWs, and when combined with AccessTUNER Pro software, the result is a groundbreaking, dyno-tunable engine management system with all of the sophistication and drivability inherent in the factory BMW ECU. A significant amount of time has been spent creating a simple, straight-forward interface that takes the mystery out of BMW's complex load-based tuning system. Intuitive changes produce predictable results and let you get down to the task of tuning. ...

      BimmerBoost member LostMarine met up at the ATCO dragstrip in New Jersey for some fun runs and a comparison with a manual M3. The blue E90 is a manual and the black E92 M3 is a DCT. Videos are from inside the E92 M3. Both cars have similar modifications with airfilters, Turner Motorsport test pipes, and mods to the OEM exhaust system. The DCT wins both races easily and the difference is quite large at over half a second and 3+ miles per hour. Videos and slips below. ...

      When we first heard about these upcoming triple turbo motors from BMW many of us scratched our heads wondering exactly how they would work. Rumors abounded. Two gas turbos and an electric turbo? A compound turbo setup? Well, this video should clear things up and explain how BMW is able to hit 381 horses and 546 pound-feet of torque in a production 3.0 liter diesel six cylinder. To have so much technology (like 3 variable turbine geometry turbos set to come on and supplement each other at different rpm ranges) not make it to the United States makes us want to cry. Watch the video and try not to shed any tears. ...

      Alex Zanardi. If that name does not ring a bell, please stop reading this and do some research about a legendary driver. Now, to be clear, this is a marketing piece. BMW did not accidentally have this happen while the X5 M was racing the M3 on the track. They chose a legendary Motorsport moment to mimic for a reason. That is fine, this still makes for a cool little video. We would like to see a real comparison of the two on Laguna Seca though just for fun. ...

      Here is the new M135i. The vehicle will be powered by the N55 single turbo six cylinder and have over 300 horsepower. How much over? Well, we expect it to be right around the same range with its crank rating as the BMW 1M. What it puts out to the wheels will be interesting to see. It will make its official debut in Geneva next month. Another interesting tidbit is that it will likely have an all wheel drive option when it goes on sale in Europe in July. Most likely not coming to the USA and we do not really mind. ...

      This is not a new comparison as it was done previously with the F10 528. Now time to see how far the N20 has raised the entry level (in the USA) 3 series game. Just by how much does it do that? Well, Insideline compared the 2010 3.0 liter N52 naturally aspirated six cylinder powered 328i to the new 2.0 liter N20 turbo four cylinder and the results are not all that surprising. The N20 328i ran the 1/4 mile in 14.1@98.9. The N52 328i ran the 1/4 mile in 14.7@94.8, fairly large difference for two motors rated at almost the same horsepower (240 for the N20 vs. 230 for the N52). ...

      The N54 had been stuck in a bit of a rut. There were upgraded turbo options out there but these were relegated to small twins often utilizing the stock housing. A large single turbo simply was necessary to take it to the next level. All the previous attempts at large single turbos had been abandoned. Vishnu showed it is in fact possible and at 22.5 PSI with 94 octane fuel and meth broke the 600 wheel horsepower barrier with a very impressive run hitting 626 although the graph was uncorrected. ...

      Why do people keep comparing the M5 to the GT-R? It is idiotic. We said as much when Autocar did it a few weeks ago. First, Mr. Harris starts with bagging on the E60 M5. The SMG III gearbox was really that confusing for him? The miles per gallon were an issue? It's a 5.0 liter V10 that revs to over 8000 RPM. Gallardo owners are not complaining about their MPG and neither was anyone who could afford an M5. The new F10 M5 is not going to be a Prius with its 17/22 MPG. Frankly, the fuel economy hit of the E60 M5 is worth it when you consider it does not need fake engine noise piped into the cabin. ...

      S85 V10 supercharger kits have lagged pretty far behind S65 development despite the V10 making its debut well before the V8. There are several reasons for this but the supercharged V10's are starting to come into their own. RPI refers to this setup as a Stage III and we are not exactly sure what that means. Higher boost most definitely but what else? Meth? Race gas tune? What fuel was used for the dyno runs and what boost? Why are these details missing? ...

      The P31 C63 AMG is a very strong car in stock form. While the regular C63 AMG and the DCT M3 is a drivers race the P31 is definitively stronger than the DCT M3 performing more like a standard C63 with a tune. So what happens when a tuned DCT M3 with bolt on's takes on a P31 C63? Well, check it out below with multiple runs from the cars. The M3 is claimed to have a tune, pulley, exhaust, and x-pipe and and the C63 AMG coupe is stated to be stock.

      Congratulations to BMS (Burger Tuning / Motorsports) for raising the bar on stock turbo N54 performance yet again. The vehicle used was a E82 135i steptronic with a JB4, down pipes, dual cone intake, CM10 meth setup, FMIC, and race gas. The mile per hour (fastest) record in the 1/4 came on a run of 11.3@125.24. The elapsed time (quickest) record came on a run of 11.259@122.86. The trap speed dropped a bit with the better ET which is not surprising considering it came on a much better 60 foot. These records were set at Famoso Raceway which is a decent track but certainly not the best strip for setting records. ...

      We already knew the BMW N20 four cylinder was underrated from its 240 horsepower rating as we saw in a dynotest of the Z4 sDrive28i which put down 233 to the wheels. That dyno was done by Insideline who recently did a dyno of the new F30 328i and overlaid it with the Z4 dyno. As luck would have it, EAS also did a dynotest of the F30 328i so we have more than one graph to go on. For the record, Insideline was wrong about claiming they exclusively had the first 328i dyno. ...
