Coming Soon: BMW Performance N55 Power Kit

BMW N55 inline-six dual scroll turbo

With all the critical acclaim BMW ‘s most recent turbo inline six the N55 has received it isn ‘t surprising to see that BMW ‘s tuning arm, BMW Performance, has already had the engineers tweak out more power.

The stock N55 features a significant number of BMW Efficient Dynamics technologies, such as direct injection, Valvetronic and a single dual scroll turbo.This is the first factory tune we are aware of for an engine featuring Valvetronic, which essentially replaces the conventional throttle butterfly with a electrical mechanism that controls the amount of lift of the individual intake valves on each cylinder. The complexity of the system had aftermarket tuners baffled for sometime. BMW Performance doesn ‘t need to hack the system, they tune the code from the ground up to be factory stable. So what are the results? Read on…

The advantage of Valvetronic is the elimination of the pumping losses and air-flow disturbance caused by a conventional throttle butterfly creating instantaneous and precise engine response. There are of courseemissions and efficiency improvements as well. In the end the system is a win-win and when you can get more power out of an engine without sacrificing longevity, efficiency or drivability we are all for it.

That is what the Power Kit will do. Indications are that the peak output will be increased to approximately 320hp and 330 lb-ft from the base 300/300. Like the current N54 twin turbo Power Kit for the 135 and 335, this new offering will be available as a port or dealer installed option. Cooling and software improvements are the mainstays for this kit but we will have more specifics including pricing and warranty information in the not so distant future.

    WOW a massive 20hp! WOOT! hehe… thats kinda rubbish but i like the warranty…

    i mean seriously! audi has been kicking ass with the inline 5 340hp.

    and if the price of this is double or triple compared to what other tuners are offering… hmmm… (like vishnu etc)

    Price? Will this be available for the 1M? Cheaper as ordered from factory vs dealer installed?

    Great to hear this is on its way!! Comparing it to the piggyback tunes already out there (BurgerTuning, Vishnu) it is a pretty mild bump in absolute HP/TQ figures. Still, at the right price the value could still be there since warranty is maintained and it’s all done with “dealer’s blessing”.

    It must also be said, conservative power gains are fine with a lot of us (the N55 is pretty muscular even in stock form) if the BMWPerf kit comes with more qualitative tuning tweaks – sharper throttle response, more aggressive sound.

    Looking forward to learning more on this when you guys get the info…

    Hey Mr. Mowse – Why would you wonder if it’ll be available for the 1M? They’ve got that car all done and it comes with ONLY the N54. This is specifically described as a performance kit. And if they had a price, they probably would’ve listed it. ::facepalm::

    Heh, car nerds. Only you guys know what those things mean.
