Alpina has revealed the production F10 B5. The car has a tuned N63 producing 500 hp. The transmission is the 8 speed automatic used in the X5/X6 M.
No word on if this vehicle will come to the USA but we don't see the point in it. The M5 will be priced around the same point and offer a dual clutch transmission as well as far better handling, power, and looks. If the price could be kept down significantly it would serve as a nice middle ground between the 550 and the M5. It makes more sense to simply tune a 550i for far less money and get better gains per dollar. ...byPublished on 06-30-2010 08:36 PM
ALSA Automotive Engineering is claiming to have completed a set of upgraded turbos for the X6 M. They modified the compressor wheels and upped the boost to 26 psi from the standard 17.4 psi. The vehicle also has high flow cats with full exhaust as well as custom tuning.
ALSA is using 30% drivetrain loss to come up with their 724 hp figure which we feel is wrong. At the most, 25% should be used a tuner should be conservative with drivetrain losses instead of using larger numbers to show inflated crank figures. Additionally, there is no graph posted or any details as to what fuel the run was made on.
The dyno is stated to read 557 whp but they do not state what type of dyno is being used. After some research, we found out they have a Dynacom 3000 Series 4 Wheel Chassis Dynomete which we are not familiar with. No baseline is established as well which further leads to questioning of the 30% drivetrain loss claim. ...byPublished on 06-29-2010 10:13 AM
BimmerBoost is going to increase its focus on older BMW's and E36's in particular. The hardcore BMW tuning scene resides largely with E36 owners and we feel the mistake all but one of the major BMW forums makes is that they do not actively focus on older BMW's and simply dismiss them.
At BimmerBoost we are about BMW performance not new BMW brand snobbery. Some of the quickest and fastest BMW's today are E36's and this is the most widely modified BMW tuner platform. It is one the best values in BMW performance and we want to provide a viable alternative to the major E36 site by providing a different perspective with better features and just a better overall site for the enthusiast.
To honor our expanding focus and new E36 forum we have collected some our favorite E36 pictures and videos from over the years into this thread. Enjoy: ...byPublished on 06-29-2010 08:03 AM
BimmerBoost is proud to announce it will be hosting a third party tuner dyno comparison at DC Performance on the weekend of July 31st. We have picked this venue as DC Performance was quick to get back to us and eager to facilitate. The facility is large, able to accommodate all the tuners and spectators as well as having two dynos which will allow tuning to take place even if the dynojet is in use.
We want to make it clear this event is taking place thanks to the suggestion and encouragement of ESS who asked for a third party dyno comparison with all the competitors in one place at the same time. BimmerBoost was able to make this happen and get practically every major player involved and we want to thank the participants for being so enthusiastic about it. ...byPublished on 06-28-2010 08:04 PM

Xcede Performance of South Africa is the first tuner to surpass the 8600 rpm DCT limit.
Yeah I am a co-owner of Xcede Performance. We have managed to get a DCt to rev 9000rpm. In fact we can get it to rev pretty much anywhere we want. And I can assure you it's not easy. BMw have hard-coded the rev-limiter outside the flash area in the DCT DME. We had to be rather innovative to make it rev there. But the car does peak around 8500-8500. But the good part is that it does not drop off to 8800rpm. It's relatively flat. So there is a definite benefit to revving 8800, evein if it peaks a few hundred rpm before that.

Here are never before seen pictures of the BMW Getrag DCT Valve Body and Solenoids. No modifications or changes are being made to these parts, they are being shown simply for their educational value. Additionally, I want to be thorough and show every last part in the transmission to very clearly prove everything was in working order.
I will leave the explanation of the function these parts serve to SSP:

Autozeitung.de is reporting that the upcoming BMW mid-engine sports car based on the Vision Efficient Dynamics concept will have the S85 V10 out of the E60 M5 along with two small electric motors giving it 600 horsepower. It seems that the car is being positioned as a direct rival to the Porsche 918 spyder.
The car will have ability to drive about 40 miles in full electric mode. It will be set up as an extremely lightweight 2 + 2. It would also be longer and wider than the Vision concept car. Chassis would be aluminum and fitted with carbon fiber bodywork keeping the weight in the 3300 pound range.
Price will most likely compete with that of the SLS, just under $200k.Did Autozeitung get this right? We don't know, we find the prospect of a naturally aspirated S85 V10 in a new car that is years away tough to swallow especially with tightening emission standards and the switch to forced induction having been already announced. We will see what develops. ...byPublished on 06-24-2010 05:22 AM
The 2010 International Engine of the Years Awards have taken place. BMW took home awards in 4 categories. Many people treat like this like the Oscars of the automotive motor world.
The 1.6 liter turbo motor in the Mini led things off the for the BMW group. This motor won the award in the 1.4-1.8 liter category for the 4th straight year.
A new BMW motor appeared on the list with the BMW N47 2.0 liter Diesel taking home the award for best 1.8-2.0 liter motor. It ousted the Audi 2.0 liter FSI motor which won the previous year. VW/Audi had dominated this category since 2005. The S2000 F20C took the crown in this category before that from 2000-2004.
The BMW N54 once against dominated the 2.5-3.0 liter category. This is the fourth straight win for the N54. The best competition in this categorically ironically comes from BMW themselves with the N55.
The BMW S65 took the 3.0-4.0 liter engine category for the third straight year. We expect this motor to continue to win this category while the M3 stays in production however there is strong competition from the Porsche flat-6's in this displacement range.
In the above 4.0 liter category we expect ...byPublished on 06-22-2010 06:31 PM
Active Autowerke is proud to announce the release of the highly anticipated Active Autowerke Supercharger System for the BMW E9X M3.
The advanced design and sleek features of the Active Autowerke Supercharger System include a front mount air-to-air intercooler system with a separate oil cooler for the supercharger unit's independent oil system. The Active Autowerke Supercharger Plenum replaces the factory air box and is designed to have an OEM-type look with custom finishes available at the customer's request. The Active Autowerke Supercharger Plenum has been designed with eight high-flow velocity stacks, and large three inch intercooler piping to supply cooled air.
The custom Active Autowerke Filter mounts to the supercharger unit and is enclosed in a custom intake box engineered to incorporate factory design while forcing cool air to the air box. The optional methanol injection system assists in lowering intake air temperatures and prevents detonation.
The Active Autowerke Supercharger System is powered by an HKS GTS8550 Supercharger Unit mounted with a custom CNC'ed bracket that uses a dedicated drive belt system, while eight high flow fuel injectors are used to supply the additional required fuel. Active Autowerkeís ...byPublished on 06-21-2010 09:14 PM
You may remember that Autocar UK incorrectly reported that the M6 would be dropped in favor of a mid-engine Audi R8 rival based on the Vision Efficient Dynamics concept. That report is here: http://www.autocar.co.uk/News/NewsAr...llCars/248568/
BimmerBoost provided a rendering of the F12 M6 in April and stated that it would only make sense for an M6 to follow considering development already went into the next gen M5 powertrain. It would be logical for the M6 to share it just as BMW did with the previous generation M5/M6: http://www.bimmerboost.com/showthrea...6392#post16392
Autoblog has provided of spy photors of the fixed roof F12 M6:
Our rendering of what the finished product may look like:
Expect the M6 to share the M5's powertrain, which means a twin turbo V8 with around 580 horsepower and a DCT. ...byPublished on 06-21-2010 08:16 PM
As some of you know my stock turbos started blowing oil awhile ago and Iíve been searching for an alternative to putting new stock ones on.As luck would have it, RB had a set ready to go so I jumped all over it. Surprise!
All I can say is these things feel awesome. Iíve been running around 17-18psi on the street on meth and pump and its great. Time was limited on the dyno and I wanted to see what she would do in race trim. Thatís 20psi and race gas. So I had BMS set me up with some settings and I did a few runs. The first couple of runs got messed up as the ignition coil signal was not secure and the dyno would stop recording. After they moved it I got a couple runs at ~20psi and then raised the boost up a touch to ~21psi, just to see how much room was left. At 21psi I actually hit the JB3 safety limiter at around 5800rpm and the dyno operator let off (oops!) but I think you all can see these turbos can hold a lot more than ~21psi if you want. The torque ...byPublished on 06-21-2010 05:46 PM
15 minutes after lines opened to reserve the Limited Edition Frozen Grey M3 the 30 vehicles were all spoken for. We would like to remind BMW this happened in the economy they did not feel it was feasible to sell the CSL and GTS in.
Larry Koch, BMWNA M Brand Managers, made the following statement, "We leapt at the chance to bring this truly special vehicle to the United States." You leapt at the chance to throw together existing packages and offer a very nice BMW individual paint and interior for over $77k? These cars are being portrayed as special so there won't be any negotiating in the price so essentially it is just a quick $2.5 million for BMW without the added cost of needing to bring a "real" limited edition M3 to the USA. ...
