These pulleys are precision made from domestic USA 6061-T6 Billet Aluminum. They have undergone thousands of hours in testing, race use, and street miles accumulated to show these pulleys work great and give you the edge. Each is precision zero-balanced and inspected for zero-runout for the best performance and to have no adverse effects on reliability, noise, or vibration. This 3 Pulley Race Set is a very popular choice: just like the 2 pulley set, a precision power steering pulley and water pump pulley are included, but VAC includes an additional underdriven alternator pulley for maximum power output on the track. We have seen 11hp and 9 ftlbs to the wheels on otherwise stock racing cars with this kit.

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 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. Kit includes: Damper Lightweight VAC Billet Crankshaft Pulley Mounting and Installation Hardware Trigger Ring for OBD1 systems Note: Will NOT work with S50B30 & S50B32 Euro Engines, For Street/Track cars with Air Conditioning, the Additional A/C Pulley Option is REQUIRED as the OE A/C pulley is not compatible. The additional mounting and installation hardware is also included. Made in the USA

Stainless steel filtration is not a new technology but is quickly gaining popularity in the automotive segment. With the ability to filter down as small as a paper filter element with the ability to be washed and reused!

The K&P Engineering filter element is made from medical grade, type 304 stainless steel micronic filter cloth to provide unmatched protection against oil contamination and resultant engine damage. A one inch square of this material flows an incredible 1.9 gallons of oil per minute at only 1 PSI pump pressure. The adhesive used in the filter assembly process is good to 600 degrees Fahrenheit, far above normal engine operating temperatures. A super strength nickel-plated neodymium rare earth magnet is installed in the top of the element for magnetic pre-filtering of the oil. The sophisticated bypass is engineered for proper differential pressures and consistent operation, delivering a greater percentage of filtered oil while being very easy to clean. The twist lock design assures positive filter element placement and allows for easy disassembly, inspection, and cleaning. The quad-ring gasket doubles the seal between the filter and the engine. Finally, the filter housing is carved out of solid 6061T6 billet aluminum, which not only looks trick but aids in dissipating heat.

K&P Engineering manufactures stainless steel filters for a vast array of engines around the world. Staying at the forefront of design and testing allows this company to offer a top-tier product for your European vehicle.

Features:

  • Consistent filtering across entire filter surface
  • Superior ASTMF316 filtration performance
  • Magnetic Prefiltering
  • Progressive rate bypass combined with high flow characteristics of the filter media avoids unfiltered oil bypassing the filter during cold startup and high rpm
  • Easy inspection of engine contamination
  • Proven in Motorsports, Military and Aerospace applications for years. Technology is FAA approved for use in aircraft. 

At regular oil changes, clean to K&P's specifications for continued used - a true lifetime filter.

Rally Road Productions, Inc. is a team supported by a group of people with great abilities in their area of expertise. From the "web guy" and driving instructor friends, to owners of various machine shops, they have surrounded ourselves with people that can be trusted to create and manufacture quality products. This is the key to ensuring everything that they sell will perform as it was intended. The goal is to increase customer satisfaction and make the customization or performance enhancement of your vehicle a more enjoyable venture.

This oil cooler system is race tested and proven to outflow the euro M3 oil filter housing. Additionally, this particular system uses a sealing mechanism to direct the oil flow through the cooler lines and then through the oil filter.  Other cooler caps do not provide this seal and therefore the external oil coolers and lines act as a "balloon".  The lines and cooler are pressurized, but oil does not flow through them.  Flowing oil means it is being cooled and not just acting as an external reservoir.

Flow testing reveals that the oil cooler cap will outflow the Euro M3 Oil Filter Housing by more than 80% at the same, pressure, RPM, and oil temperature. In the upper RPM range, there is nearly a 100% improvement in flow from the RallyRoad oil cooler cap when compared to the Euro M3 oil filter housing.  This is a massive improvement over OE and is a worthwhile upgrade, especially in engines that see severe duty.

Features:

  • -8AN o-ring ports to provide a leak free fitting without the use of Teflon tape or sealant used by other oil cooler caps.
  • Viton o-rings are used throughout to maintain function and sealing in a high-temperature oil environment.
  • Use of the stock filter cap bolt to reduce cost and simplify installation.
  • An internal sealing mechanism to direct oil flow through the oil cooler and through the filter.
  • 1/8" NPT side port for external oil pressure gauge.

Kit Includes:

  • Oil filter cap with fittings
  • Oil filter sealing ring
  • BMW MANN Oil Filter and gasket

If you're not sure if your Vanos seals are bad then the only question you need to answer is if you've replaced them. Every unit from the factory came with the same failure prone o-rings and seals, even the re-manufactured units you can still get today. The only real fix is by replacing the seals and o-rings with material that is built to last in the oiled, extreme temperature environment found in these kits. 

A premium product replacement with easy to follow instructions makes rebuilding your Vanos unit a must. Even thought the power loss is barely felt it's the opposite result once you replace the seals, every car that gets rebuilt ends up wowing the customer and all of them saying they didn't realize what they lost. 

There are a number of symptoms that will plague your car as a result of these failing seals such as erratic idle, engine hesitation, stalling, and increased fuel consumption to name a few. If you've been chasing down any of these symptoms with no fix then this could be your issue.

While you 're replacing the seals in your Vanos unit it a good time to install anti-rattle spacers to tighten up the gaps in your stock assembly and get rid of that noisy Vanos clatter.

2003-2005 E85 Z4 3.0-liter Stage 1 Performance Package
Peak Power Gain: +17hp / +8ft-lbs
Rev limit: 7000
Octane: 91 or higher

Our Stage 1 kit featuring a cold-air intake kit and performance software. The aFE intake is made from high-quality materials, reducing underhood temperatures and not contributing to heat soak of the air filter. aFe's Stage 2 Intake uses an oiled cotton air filter for maximum air flow and excellent filtration. The kit is supplied complete with heat shield, ABS plastic intake tube, sealing materials, hardware, and install instructions.

The software is tuned by BMW tuning whiz Jim Conforti and supplied with the Shark Injector. The Shark Injector is a do-it-yourself reflash tool that plugs into the OBD diagnostic plug in your dash. With the push of a button, it will copy your stock software and reflash your computer with the performance tune. You can set it back to stock at any time by following the same procedure.

Both of these items work together to bring up huge torque increases and much improved driveability. They provide a solid performance boost with a low upfront cost. For an excellent 'bang for the buck' upgrade, the software and intake are a great choice.

2003-2005 E85 Z4 3.0-liter Stage 1 Engine Upgrade includes:
aFe Cold Air Intake
Shark Injector performance software

Applications:

This anti-theft throttle controller from Dahler lets you custom-tune your throttle's responsiveness and the security of your vehicle. With 5 preset modes from valet mode to track mode, there are no limits to what you can do. The anti-theft feature completely disables the throttle when activated, so when if in an unfortunate theft situation, even with the car started and in gear, there is no way your car can move, saving your vehicle from falling into someone else's less-than-legal possession. COMFORT MODE (blue) Unfamiliar terrain and too much traffic? This mode lets you take it easy. Your gas pedal reacts less sensitively – especially when starting off. Your stress level will thank you. ECO MODE (green) $5.00 a gallon? There are a few tricks you can use to save fuel and money when driving. This driving program supports you in reducing the average fuel consumption of your BMW if certain rules of economical driving are observed. SPORT MODE (red) This driving program gives your vehicle a much sportier character. Your BMW reacts with a significantly better response and a straighter acceleration. The response time of the engine is significantly improved. TRACK MODE (purple) If you are not yet satisfied with the sports program and you like to push yourself to the limit, then give it a try. For those who go on tracks or run cars with 85 Ethanol this mode might be the right choice.

Still looking for more power after bolt-ons? High performance camshafts from Schrick are the way to go. These cams are a direct replacement for the stock cams and give a solid 15+ horsepower boost at the top end and great midrange torque increases too! More gains can be expected with intake and header upgrades and custom software tuning. A slightly lumpy idle is expected at cold start but will be smooth once at operating temperature. This set is just a great all-around cam upgrade for the S54!

These Schrick cams were initially developed for the M3 CSL but they also work great on the US and other non-CSL S54 engines as well. With more duration they are a great match to high flow headers, no cats, or CSL intake manifold upgrades. These are the new "cast" cams from Schrick which require new rocker arms (Schrick recommended or BMW part #11337833259). Professional installation is a must due to the intricacies with the double VAN0S.

One major hurdle for a track-only car is the limitation of the hydraulic valve lifters in the M50, S50-US, M52, S52-US, M52TU, and M54 engines. These effectively limit your revs to 7200-7300 RPM as the valves 'float' at higher revs, leading to piston-valve contact. By converting to a machined solid lifter, and upgrading other areas of the engine, you can configure the valve train to withstand high RPM running. Not only can you tune for more power, you can help prevent damage during a mild mechanical over-rev.

This kit includes the mechanical spacers to convert hydraulic lifter tappets to solid lifters. The lifter bucket remains in place with the Schrick solid tappet replacing the original. These work on all M50, M52, S50, S52 and M54 engines and were proven in normally aspirated as well as supercharged engines. A custom camshaft is required.

Professional installation and setup is mandatory as these require complete assembly of the head, checking valve lash, then dis-assembly and machining of the Schrick tappet to spec. This kit includes enough spacers for 24 valves. We also carry individual parts, if you are looking for single pieces. This price is for a full set of 24.
