The VAC Motorsports Crank Seal Guard, made of 6061 Billet Aluminum, prevents your serpentine belt from being pulled into your engine, a common problem amongst BMW N54, N55, and S55 Engines. Without a crank seal guard, the serpentine belt on N54, N55, and S55 engines is commonly sucked into the crank hub area past the crank seal, where it enters your engine and disrupts engine timing. When this occurs, the belt is shredded and clogs engine oil pickup, starving the engine and reducing oil pressure, causing catastrophic engine failure and thousands of dollars worth of damage. VAC Motorsports’ Crank Seal Guards are precision machined for perfect fitment and provide rigidity and maximum protection. We designed our guard with self-locating pilots to perfectly seal the crank hub bore and provide even, minimum clearance around the crank hub. Installation Hardware included. Made in the USA.

If you're grappling with issues like crankshaft failures and oil pump breakdowns in your BMW 6-cylinder engines, you're not alone. Even seasoned mechanics can overlook the critical aspect of harmonic resonance control in these inline-6 motors, despite their optimal configuration.

Enter ATI Performance Products in collaboration with VAC Motorsports, presenting a solution in the form of new dampers tailored for BMW 2.5L, 2.8L, 3.0L, and 3.2L straight-6 engines found in various models like the E36 and E46 M3, E9X, and E6X, as well as newer Z3s and Z4s. These dampers effectively nullify crankshaft harmonic vibrations, paving the way for enhanced horsepower and torque output, alongside a reduction in internal engine wear. Say goodbye to issues like fractured oil pumps and timing chain mishaps! By pairing these dampers with a VAC accessory pulley, you seamlessly replace the OEM balancer. Featuring a 7” outer diameter and OEM-style timing alignment tabs, these ATI Super Dampers boast SFI 18.1 Safety Certification, ensuring they're competition-ready.

What sets the ATI SuperDamper apart? It's the remedy for vibration woes in inline 6 engines, especially those equipped with lightweight clutch and flywheel setups. Expect diminished wear on bearings, engine accessories, and oil pumps, all while being compatible with underdrive pulleys.

Included in the kit are the damper itself, a lightweight VAC Billet Crankshaft Pulley, along with all necessary mounting and installation hardware. Note that it's not compatible with S50B30 & S50B32 Euro Engines. For street/track vehicles with air conditioning, opting for the Additional A/C Pulley Option is imperative, given that the OE A/C pulley isn't compatible. Rest assured, all required mounting and installation hardware is included, and the entire package is proudly Made in the USA.

NOTE: Due to space limitations, the design of this damper will overdrive your components (water pump, power steering, and alternator) by approximately 10-13%; we highly recommend using underdrive pulleys in your setup Controlling the harmonic resonance of the BMW S14 engine is highly important as RPMs rise, but the ideal configuration of the 4-cylinder motor makes even the most experienced engine builders overlook some fundamental principles of engine harmonics that can be destructive. Harmonics destroy these motors by causing extensive oil pump and crankshaft damage, but the addition of VAC’s Harmonic Damper eliminates the unstable crankshaft harmonic vibrations that cause internal engine wear. By eliminating harmonic vibrations, your S14 engine will be able to produce more horsepower and torque with increased reliability. The VAC/ATI Harmonic Damper is made with an integral pulley, eliminating the need for the additional pulley other models require.

Elevate your engine's performance with a choice of compression ratios that suit your needs. Opt for stock compression when conducting a basic engine rebuild or for low boost turbo or supercharger applications. If you plan to run high-performance camshafts, added compression can significantly enhance your engine's capabilities. On the other hand, if you're aiming for a big boost turbo setup, low compression is the way to go.
