How Turner Motorsport Can Add Over 100HP to Your N55-Powered BMW

If you have an N55-powered BMW like the F30 335i or F22 M235i, chances are, you are looking to maximize your power potential. Fortunately, thanks to BMW’s signature straight-six turbocharged power plant, you have tons of room to go up with a little help from your friends at Turner Motorsport. We have spent the few years since the N55’s introduction developing the best combination of parts to make the biggest difference to your power output and have learned a thing or two about making a real recipe for success. This week, we’re going to show you what Turner Motorsport can do for your N55-powered BMW for power and performance.

“Power Packs” are all the rage. A one-click option that has everything you need in a single box to go from bone stock to hair-raising horsepower figures means you spend less time trying to figure out what works and what doesn’t. The experts in our R&D facility already did that groundwork for you by testing, designing, developing, and producing a proven set of upgrades that offer measurable benefits on the dyno and in the driver’s seat. It would be hard to beat a recommendation that has all the data behind it, especially one that saves you time and money. For the N55, our Stage 3 Power Pack kit is your best bet and will help you maximize the performance potential from your engine.
What’s in the Kit

Our Stage 3 Power Pack includes all the usual suspects when it comes to improving performance in a turbocharged BMW engine. The kit includes:
Turner Motorsport Performance Software
Turner Motorsport High-Flow catalytic converter/Downpipe
Turner Motorsport N55 Intake
Turner Motorsport Stepped Intercooler
Let’s look at the individual components by themselves and break the kit down with what each part can do for your car. This will tell us exactly how they all work together and why this shortlist is enough to make a massive difference in your driving experience.
Turner Motorsport N55 Intake
Turner Motorsport Intake

Our intake system was designed to improve airflow and decrease intake air temperatures while offering an attractive upgrade to show off when you pop the hood. While that is a description of every intake on the market for any car, ours has been carefully designed to maximize its benefits in terms of both looks and performance to meet and exceed your expectations of quality that drew you towards a BMW in the first place. We designed this intake to fit seamlessly with the stock mounting locations and ducting, which offers a simple installation and attractive fitment for that OEM+ look, as it retains much of BMW’s original design intentions but improves on their quality with either a gloss or matte carbon fiber intake tube that replaces the BMW plastic version. Lastly, on its own, the intake is capable of 7WHP and 14ft-lbs of additional power, so the need is certainly more than just an attractive replacement. It offers true performance benefits as well, thanks to our extensive research and testing on real vehicles with real data available for you to see for yourself.
Turner Motorsport Stepped Intercooler
Turner Motorsport Stepped Intercooler

Sharing the theme of moving higher volumes of colder air with better flow, the Turner Motorsport Stepped Intercooler increases the surface area of your charge-air cooler by a respectable 56% and decreases inlet and outlet air temperatures dramatically. This means colder and denser air will flow more smoothly for better power delivery and less pressure drop. How much power on its own? A hearty 18WHP and 10ft-lbs of torque just by itself. But the point is to maximize the efficiency of all these systems, right? We’ll get to that.
Turner Motorsport High-Flow catalytic converter/Downpipe
Turner Motorsport High Flow Catted Downpipe

While the intake adds a visual element and power, the High Flow Catted Downpipe adds auditory and power elements. Driving your BMW is a full sensory experience, or at least, it should be. This downpipe is designed to not only sound incredible and give you a more satisfying feeling every time you press the throttle but to also help push out more power when you do. With OE fitment, it sits just the same as the factory version but puts out peak gains of 11WHP and 37ft-lbs of torque just by itself thanks to the R&D efforts that helped maximize the flow of spent gas from the hot side of your turbo. Again, these upgrades by themselves are great, but making them all work together and do the most for your engine is the point.
Turner Motorsport Performance Software
Turner Motorsport Performance Software

Anyone can throw parts in a car and make it faster, but an expert knows how to get the most from all the parts by looking at the total package. That’s where our expert calibrators come in with the extensively tested Turner Motorsport Performance Software Upgrade for your N55. After tons of tweaks and real-world data collected, we were able to develop a software tune that takes all the upgrades included in the Stage 3 Power Pack and composes a symphony rather than host a disorganized garage band practice. The software maximizes the potential of all these upgrades together and pulls more power than the parts could individually, or combined, without the software upgrade. How much power, you wonder? On the dyno, with this simple list of upgrades, our N55-powered BMWs achieved a peak gain of 110HP and 174ft-lbs of torque. You read that right; with just a few parts and simple tune, something that can easily be done over a weekend even if you work slowly, we added over 100hp and nearly 175ft-lbs of torque. Most people are happy with a ten or twenty HP increase, but over 100HP from this kit means your N55 is in a different class entirely.

Also included in this kit is all the hardware you need to get the job done right. Nothing is left out. Our intention is to give you an all-in-one solution to reach the highest power figures we achieved with the same parts to let you experience the fruits of our labor and the years of knowledge we have accumulated from doing this day in and day out with our shop cars, race cars, and even our daily drivers. With this kit, you can expect a complete transformation of your F3x or F2x into something remarkably fun yet still fully enjoyable on the street for your daily commute or a spirited drive through the twisties on the weekend. By giving you everything you need in one box, all the testing, all the guesswork, and all the learning has already been done for you. All you need to do is go out, start wrenching, and take advantage of the 110hp and 174ft-lbs of torque Turner Motorsport can give your N55-powered BMW with the Stage 3 Turner Motorsport Power Pack.
