    • BMW will offer a factory N55 powerkit, power boost to about 320 horsepower + retaining warranty

      We have learned that an N55 powerkit will be coming relatively soon from BMW for all models. What will it consist of? Well, it will be very similar to the N54 powerkit offering a slight bump in power and cooling upgrades. This will of course maintain the factory warranty and be available as an option during the order of the vehicle or to be installed at the dealer. The engine will go up to about 320 horsepower and 330 pound-feet of torque from the standard ratings of 300/300. Pricing and details to come when the official announcement is made.

        The breakdown is very informative. So with a Power Kit, CAI, full exhaust (when it is available) and coilovers & swaybars, oh and big brake kit would be about right. Hmmm... I still like the N54.

        Wouldn't put much stock in AFE's dynos.

        Show me an independent dyno.

        EXACTLY. Was about to mention this, people have dyno'd with their intakes in the M3 scene and lost power.

        Lots of choices out there. Seems like BMW is charging a lot for an auxillary radiator and and a software upgrade to up hp by 20. What about getting the Dinan oil cooler and a JB3 chip, or even a Dinan chip? Schnitzer gurantees the warranty and can do it all too although they are the most expensive option, and not necessarily the best, in my opinion. These options all should take you to about 360 hp for the same money excluding Schnitzer. I understand there are some concerns about going beyond 360 hp. Once you go past that, you may need a heavy duty clutch, reinforced engine mounts, updgraded brakes, etc., and now we are talking lots of money so a M3 from the get-go would have been the way to go. Does anybody know what the best way to go here is?

        Depends what you want, if you are looking for power you don't need to spend a ton.
