Free additional power to your M3’s rear wheels without sacrificing or compromising your BMW’s reliability. Machined from 6061-T6 aerospace aluminum, Macht Schnell Performance Underdrive Pulleys are strong as well as lightweight to limit parasitic drag from the accessories within a moderate level for maximum performance on or off the track. After machining and engraving, pulleys are then T3 hard anodized for additional strength, anti-corrosion & wear resistance. Our DualDrive design replaces the Crank Accessory & Power Steering Pulleys, resulting in an additional 9-14 HP and 7-9ft. lbs TQ gain for the M3. Gains are due to a reduction in power required to turn accessories; an increase in accessories lifespan due to lower speed will also result. All factory harmonics/balancing are undisturbed. Macht Schnell Performance Underdrive Pulleys have no negative effect on accessory operation and comes fully equipped with new belts. Already have this kit and need new belts? See T#14491 and T#14489 Performance Underdrive Pulleys Features: DualDrive design allows maximum performance, with minor effect on accessory speed Proper cooling temperatures are retained at proper levels on or off the track Maintains proper alternator speed, allowing sustained levels to sensitive control modules Machined from 6061-T6 aerospace aluminum T3 Hard-Anodized for maximum strength and corrosion/wear resistance No affects to crankshaft dampening or harmonics Simple bolt-on installation

The early N55 turbocharger is notorious for pneumatic wastegate actuator failure, a common issue that triggers frustrating boost errors and persistent check engine lights. Because BMW does not provide this specific component as a standalone replacement, owners are often left with few official repair options. Pure Turbos solves this problem with an upgraded actuator engineered to fix the inherent weaknesses of the original equipment while simultaneously boosting the efficiency of the entire turbocharging system. One of the primary benefits of this enhanced actuator is its ability to deliver approximately 2 psi of additional boost compared to the factory unit while maintaining the same Wastegate Duty Cycle. By optimizing how exhaust gases are managed and bypassed, this component allows the engine to generate more power without requiring more effort from the electronics. This increased pressure translates directly into sharper throttle response and a noticeable jump in horsepower, making it an essential upgrade for drivers who want to restore their vehicle's reliability while enjoying a more aggressive and responsive driving experience.

As BMW enthusiasts, we admittedly did not know how to feel when BMW moved to forced induction. We loved the naturally aspirated power that the NA straight six produced, but Pure Turbos has been able to prove time and time again what a forced induction BMW powerplant is capable of putting down. Here at Turner Motorsport, we trust Pure Turbos to meet all of your power desires - after all, there's a reason the majority of the fastest forced induction BMWs on the road are running Pure Turbos. If the stock power of your BMW's N54 isn't quite enough for you but you also don't want to go too crazy, this Stage 1 turbo upgrade from Pure Turbos is the best option on the market! With just a few supporting modifications you can easily achieve 450+ reliable wheel horsepower, enough for a bit of fun but not too much to make things unwieldy. In addition to Pure's turbo modifications, these turbos have machined inlets to alleviate issues with inlet hoses popping off. Two options are available: the stock size of 1.81" (this kit) or with 2.0" oversized inlets (T#578261) for use with oversized pipes.

2007-2010 E90/E92/E93 335i N54 Stage 1+ Performance Package
Peak Power Gain*: up to 103hp / 108ft-lbs
+ aFe Pro5R Dual Cone Intake
+ Wagner Front Mount Intercooler
+ Cobb AccessPort programmer

More power = more heat. It's easy to make more power one time but to continue making that power consistently requires careful planning and design. With the additional boost the air entering the engine is also warmer, making the intercooler more important than ever. In testing, the stock BMW intercooler was quickly overwhelmed and cannot keep the intake air cool enough. The engine computer recognizes that and dials back the boost. A more efficient intercooler will keep boost levels up, delivering consistently higher boost levels. The Stage 1+ package includes a Wagner Evo I plug and play intercooler upgrade. We get great feedback from our customers and technicians about the Wagner FMIC - it's a direct bolt in part using all of the factory piping and it offers 85% more surface area than the factory intercooler.

The aFe Dual Cone intake and Cobb Accessport programmer complete the Stage 1+ package. The larger surface area of the aFe cone filters allows more air to enter the engine - creating more power and torque, a richer engine sound, and better throttle response. The kit is supplied complete with aFe Pro5R filters, mounting shield, intake tubes, sealing materials, hardware, and install instructions. The torque increase and sound from the open intake from low-mid RPM is sensational.

The Cobb software tool puts multiple tuning stages in the palm of your hand. Our Stage 1+ package lines up with the Cobb Stage 1 tuning maps for an intake and FMIC (91 or 93+ octane fuel). Simply download the Stage 1+ map from the Cobb website, plug it in, and install. Select different maps for other upgrades, throttle settings, octane ratings, valet mode, or revert back to stock! If you're moving up in Stages simply download a new file from the Cobb website and update your AccessPort programmer! The AccessPort triples as a diagnostic tester/reader and a data logger. It's the most feature-packed programmer on the market today.

We have taken the guesswork out of choosing the best upgrades for the N54 engine. If you follow the upgrade path we have laid out you will have very satisfying and reliable results. The addition of the larger intercooler makes Stage 1 more enjoyable and won't let you down at the track or dragstrip. * Note that peak power gains are quoted remain the same as Stage 1 but the cooler intake air means there is less of a chance the engine computer will cut power from heatsoak.

This item fits the following BMWs:
2007-2010 E90 BMW 335i 335xi 335i xDrive - Sedan
2007-2010 E92 BMW 335i 335is* 335xi 335i xDrive - Coupe
2007-2010 E93 BMW 335i - Convertible
* 335is horsepower gains are lower due to the factory power boost in the "is" package

The TTE550 for the N55 motor. Still keeping the original turbocharger the compressor wheel is exchanged for a TTE milled aluminum wheel with state-of-the-art geometry, 7+7 blade so producing extra power. Equally, The Turbo Engineers change the original exhaust turbine for a far larger but very lightweight 9-blade TTE-designed turbine for lower exhaust gas backpressure giving greater performance, yet still giving a good spool response. The Turbo Engineers also fitted a TTE motorsport upgrade bearing system for durability. Equilibrium Precisely balancing the turbochargers is a key critical factor to becoming a TTE upgrade unit as longevity and performance are paramount. Good balance improves acoustics also. Subsequently, great care is taken with all TTE turbochargers to achieving balance standards. Firstly, parts are balanced at slow speeds up to 2800RPM in multiple planes using a single parts machine, then components are assembled and the CHRA are dynamically balanced, but this time depending on the application at up to 250,000 RPM in multiple planes using an in-house VSR machine to acquire the ultimate equilibrium, to a standard far higher than OEM. Each turbocharger is supplied with a serial-numbered balance test result document. Features Genuine Housings & Components Highly Efficient Next Gen Billet Compressor Geometry Optimised Compressor Cover Machining Clearances Genuine diverter valve Fitment As Original.
