If you are breaking crankshafts and oil pumps, the cause may be a mystery to you as it has been to many of our customers. We know that controlling the harmonic resonance of the BMW 6 is highly important as RPMs rise, but the ideal configuration of the inline-6 motor makes even experienced engine builders overlook some fundamental principals of engine harmonics that can be destructive. ATI Performance Products has partnered with VAC Motorsports to develop new dampers for BMW 2.5L, 2.8L, 3.0L and 3.2L straight-6 engines found in the E36 and E46 M3, E9X and E6X, as well as newer Z3s and Z4s. These dampers eliminate crankshaft harmonic vibration, which allows the engine to produce more horsepower and torque, while also reducing internal engine wear at the same time. Broken oil pumps and timing chains will be a thing of the past! When used with a VAC accessory pulley, these dampers are a direct replacement over the OEM balancer. They have a 7” outer diameter and include OEM style timing alignment tabs. BMW enthusiasts should know that all ATI Super Dampers exceed SFI 18.1 Safety Certification and are approved for competition. The advantages of the ATI SuperDamper include eliminating vibration issues with inline 6 engines equipped with lightweight clutch and flywheel assemblies, reduced bearing, engine accessories, oil pump wear, and compatibility with underdrive pulleys. Includes lightweight VAC Billet Crankshaft Pulley.

Staying on top of your belt maintenance is the smart move. Cracked or worn belts are a recipe for a headache or worse. The main drive belt runs critical components - the alternator, water pump, and power steering pump. The pulleys contain bearings that may be worn when it comes time to replace the belts. You can check the pulleys by relieving tension on the belt and feeling each pulley for play or grinding. The tensioner also sees similar wear. If your pulleys are new or don't need replacement, you can pick up the belts on their own.

Eliminate your squeaking accessory belt pulley and cracked drive belt with this upgraded accessory belt service kit! This kit includes ECS Kevlar Reinforced Drive Belts, tensioner assemblies, and new tensioner pulleys. ECS Tuning's Red Kevlar Accessory Belts are both an aesthetic improvement and a performance alternative to a traditional belt. Kevlar-reinforced belts experience less elongation over time minimizing the amount of belt adjustment needed as well as offering a higher shock and impact resistance compared to OEM-style belts. Refreshing the rollers and/or tensioners simultaneously is a great way to ensure all vital components of your drive belt system are functioning optimally for years to come!

Under certain conditions, the N55 crank hub likes to spin, without warning and even when the engine is in perfect health. The engineers at Vargas saw and dealt with this problem time and again, and they saw fit to do something about it. This hub uses a proprietary "Spline Lock" technology that uses high tolerance machined splines which press into the crank, and positively lock the hub to the crank. The splines are machined in such a way that rotational forces drive the hub, and splines deeper into the crank meaning when the hub encounters a situation that would normally slip a stock hub the splined hub is driven into the crank to keep it in place (much like a splined extractor). Features: Installs the same as a stock hub Does NOT require the crank to be drilled for pins Manufactured from Harndered 17-4SS We suggest the Crank Hub System ONLY be installed by a qualified shop or technician. Timing tools are 100% REQUIRED if installed improperly engine damage may occur. DISCLAIMER: VTT and ECS are not responsible for any engine damage caused by improper installation, or misuse of the crank hub solution.

Anyone with a modified N55/S55 knows the risks involved with the OEM Crank Hub. When the engine simply can't handle the stresses its put under or the design is such that it simply does not support extreme conditions, issues can arise. Under certain conditions, the N55/S55 crank hub likes to spin, without warning and even when the engine is in perfect health. MMR has produced a EN36 machined billet one-piece crank hub heat treated with a 0.75mm case hardening which makes it extremely durable. Due to the one-piece design, it ensures that the friction plates cannot slip. This offers a huge jump in reliability when paired with a new properly torques crank bolt. Installation is requires no drilling or modification to the OEM crankshaft ensuring a perfect fit! Included in this kit is MMR's T-6061 machined billet aluminum capture plate anodized in their trademark finish. The MMR Performance capture plate secures the head of the OE crank bolt and prevents it from turning or being able to loosen. *Installation recommended by a professional shop or technician.

BMW has a seemingly endless number of fans of the N54/N55/S55 engines, three straight-six turbo engines that are each capable of 750+ horsepower, but that doesn't mean they were without their faults! BMW's N54 had a notoriously rocky start with reliability due to multiple issues such as fuel injectors failing, turbos failing, serpentine belt failure, crank hubs coming loose, and more... BMW made multiple attempts to fix the issues plaguing the N54, but they could only do so much and the fixes rolled out seemed temporary at best. Following the N54, BMW released their updated N55 and S55 engines, giving many people hope that these engines would address the previous issues. Unfortunately, this was only some-what the case. Crank hubs and crank bolts continued to loosen over time and serpentine belts continued to shred themselves and get pulled into the oil pan through the front main seal. For all three engines, this meant a single failure could effectively turn your engine into an oversized paperweight. Luckily for us, the BMW community is full of skilled enthusiasts who have gladly taken up the task to offer solutions! The first headache to be addressed was the Crank Hub and Bolt. Using a simple plate that fits perfectly over your crank hub's hex-head bolt and mounts up against the damper, the crank bolt is effectively locked in place, preventing it from being able to back out until the plate is fully removed. Next up was the serpentine belt failures. It's not known what exactly causes the serpentine belt to split, but once it does, the pieces hanging off of the belt wrap around and behind the damper. This leads to the belt breaking up into smaller pieces and eventually getting pushed between the crank hub and rear main seal into the oil pan. These small pieces of debris get caught in and block the oil pickup, preventing oil flow and leading to engine failure. To prevent this, multiple aftermarket companies came up with their own versions of Crank Seal Plates. This plate is installed behind the front damper, blocking the opening that allows the serpentine belt to pass between the crank hub and seal, keeping debris out of your oil pan! Also included in this kit are the components to service your front Oil Cooler/Filter Housing gaskets, refresh your drive belt system, and install the aftermarket upgrades.

The idea of power pulleys is simple. The less effort the engine puts into running accessories such as the water pump, power steering, pump alternator etc., the more of that power can be used elsewhere - your wheels! The way this is done by reducing the rotation of the pulleys by as much as 10-20%! The end result is more horsepower at your disposal. Turner has done extensive testing (on and off the track), to ensure that the accessory systems still function as intended and without failure. These pulleys offer an excellent compromise of power gains, reliability, and performance.

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?

Rogue Engineering has developed a power pulley kit that reduces the drag on specific pulleys while allowing others to remain at their same efficiency. This allows for perfect operation in daily driven vehicles without a hiccup or stutter. However, when the demand for power is requested, the power pulley kit allows for the freed power to become apparent. The term "power" pulley is a bit of a misnomer. Underdrive pulleys actually free up power by reducing the drag caused by the accessories. These pulleys are based off a calculated percentage from factory dimensions, so that particular component speeds are safely reduced without affecting their true purpose.

Every time the cylinders fire, torque is transferred into the crankshaft. The crankshaft deflects under this torque, which sets up vibrations when the torque is released. At certain engine speeds the torque imparted by the cylinders are in sync with the vibrations in the crankshaft, which results in a phenomenon called resonance This resonance causes stress beyond what the crankshaft can withstand, resulting in crankshaft failure. The accessory pulley acts as a balancer and prevents these vibrations from destroying your crankshaft.

Continental is the OEM supplier for the stock serpentine accessory belt on your N52 engine. They are also the OEM for many other components on your entire car. This extensive kit covers many of the common wear items that should be changed any time the serpentine belt is being replaced. As these cars gain years and mileage the belt tensioners will also need to be replaced along with the actual belts. It won't do any good to replace the belt if the tensioners are worn. This kit will save you time and money over buying these pieces individually and you get OEM-quality over any 3rd party aftermarket brands.

Included in the accessory belt and tensioner kit is:

main drive belt, 11287549150
mechanical belt tensioner with pulley, 11287530314
deflection pulley, 11287535860
mounting bolt

On the N52 engine the main drive belt also runs the A/C compressor and it all runs from one tensioner.

This item fits the following BMWs:
2008-2012 E82 BMW 128i
2006-2011 E90 BMW 325i 325xi 328i 328xi 328i xDrive 330i 330xi - Sedan
