SPECIALIZED SERVICES | BMW
WHY ARE THEY SO IMPORTANT?Specialty repairs are not offered at your average repair shop because most repairs of this nature require factory training, specific tools, extensive experience and a unique knowledge to execute them properly. Excelerate Performance has brought all of these requirements together into one shop so that your specialty repair doesn't become especially disastrous.
FACTORY MAINTENANCE & REPAIR
Looking for OE specified maintenance without the OE specified prices? Or perhaps you’re tired of your dealership’s antics? WE are the dealer alternative! Excelerate Performance is completely knowledgeable and capable of performing factory maintenance and service utilizing OE maintenance schedules. We have you covered from mile zero to the last mile and covering all services in between, whether it be a 10k, 20k, 60k, 90k or 250k.
TIMING BELTS & TENSIONERS
What is a timing belt and why is it so crucial to proper engine operation? This belt maintains synchronization and control of the timing components, i.e. the crank, cam(s) and the valvetrain. So why does your timing belt need to be replaced? The timing belt is a rubber product and resides in a sensitive environment where it experiences extreme heat cycles. The extreme heat cycles and constant tension place a lot of stress on the belt, causing it to dry out, stretch, crack or snap. If this happens it can be catastrophic and cause complete engine failure. We highly recommend that you follow the factory recommended maintenance intervals and be proactive about preventative maintenance. If you wait too long you may wind up in a bad situation with an even bigger problem.
FLUID FLUSHES AND SERVICES
Changing the fluids on your vehicle leads to vehicle longevity and better performance. Fluids used in the oiling, coolant, brake and power steering systems break down over time and lose their lubrication properties. When that occurs you get metal on metal, which leads to high temperatures and ultimate failure. Sometimes just a drain and fill is sufficient. But with brake systems, power bleeders and automated flushing devices allow us to improve efficiency, ensure accurate bleeding, and consequently this reduces wait times and costs for customers. Not sure when to bring your car in for these services? Be sure to contact our service department.
Alignments & Tire Changeovers
An alignment is important because it dials in your vehicle’s suspension. A proper alignment will improve the potential of your vehicle’s performance and safety on the road, while also preventing unnecessary and uneven tire and suspension wear. However, not all alignment systems are created equal, and neither are all alignment technicians. Excelerate Performance’s alignment experts use the best equipment on the market, the Hunter Hawkeye Elite alignment system, and the exact specifications provided by the original manufacturer of the vehicle. The specifications, equipment, and technician allow us to properly align the camber, caster and toe of your vehicle.
AUTOMATIC TRANSMISSION SERVICE
Many OEMs claim “lifetime fluid” for your automatic transmission. But what do they consider the lifetime to be? 100k? That’s unacceptable. Your automatic transmission has a filter and fluid and over time the filter gets clogged and the fluid breaks down. Change your fluid and filter regularly and extend the lifetime of your transmission as a few hundred dollar service every 30-50k is significantly less than a new transmission every 100k.
Ignition component maintenance (spark plugs, ignition wires, ignition coil packs, distributors, etc) is invaluable. When your ignition operation suffers so does fuel economy, engine performance and overall wear on the engine. It might have even gotten to the point where your Check Engine Light is flashing at you. That means the vehicle is misfiring and you should stop driving the car before you permanently damage a cylinder or the catalytic converter. A good rule of thumb is to replace spark plugs every 30-40k miles and coil packs just as frequently. In some cases, these items are particularly subject to failure when upgraded software is installed, particularly because the demand and stress on these parts is increased significantly. Replacement as preventative maintenance also never hurts.
Suspension components are commonly overlooked when it comes to maintenance. However, suspension items are wear items as well. Most suspension bushings are made of rubber because the material dampens vibrations; this rubber wears over time and becomes sloppy and tears or can even crack and fall apart. Shocks and struts become soft over time and eventually the seals will begin to leak, causing your suspension to feel “floaty” and bouncy. Other key components also have wear items like strut mounts, control arms, sway bar bushings, end links and more. All of these need to be maintained in order to safely drive your vehicle.
S54 VALVE ADJUSTMENTThe S54 has been known to be very reliable sub breed of BMW’s lower output M54 engine but requires maintenance to last like any other engine however, more frequent maintenance is required for the engine’s longevity. The M3 e46, Z3M, Z4M with the S54 engines all use mechanical valve lifters which have a higher RPM capability despite their ongoing adjustment requirements. So, why is a valve adjustment so important? Without proper valve clearance the valves will not seat fully. A partially open valve will result in compression loss and improper valve cooling. The final result is burnt valves. When this happens you must remove the head and send it to a machine shop for a valve job. This is a far more complicated repair process than can be avoided by a little maintenance. This now extended repair will now lead you to having to replace unnecessary parts that are not typically known to not be a problem. When letting these maintenance items go too long without being addressed you usually find yourself fixing things that never needed to be replaced in the first place.
What is a valve clearance and why is it important to adjust valve lash or clearance? Valve clearance is the space between the rocker arm and the camshaft. Why important? If you have too much or too little clearance it can quickly cause extreme damage to your engine. But before the catastrophe comes reduced performance, a noisy valve train, poor gas mileage, excessive emissions, etc. But in order to adjust valves properly you need some special tools, measurements and knowledge. Excelerate Performance’s service team has it all. Contact us to find if you need to have your valves adjusted!
CARBON CLEANINGIs direct injection plugging up your intake system and valves with carbon? You might ask, what is direct injection (aka (GDI) Gasoline Direct Injection or (FSI) Fuel Stratified Injection) and does my car have it? Direct injection sprays fuel directly into the combustion chamber instead of into the intake track. This is a faster and more efficient way to get fuel into the cylinders which leads to better fuel economy and cleaner emissions. With any advance in technology comes great benefits, but also some consequences. In this case, carbon buildup is the leftover downside of a great advancement. By spraying fuel directly into the cylinders you lose the ability to burn off carbon on the back of the intake valves like older model vehicles. Carbon from EGR and PCV systems find their way back into the engine to be re-burned; but without the fuel spray to de-carbonize you are left with a mess that needs to be cleaned. Common symptoms range from rough idle, lost power, slow acceleration, misfires and even poor fuel economy. Don't worry. We have the tools and expertise to get you back on track for performance and fuel economy. Whether it be with our FuelKare Decarbonizing machine or the good ole hand scraping and cleaning of the valves, we'll get you taken care of.
OIL FILTER HOUSINGMany e9x cars have three common problems at around 100k miles. 1) Failed oil filter housing gasket 2) Failed water pump and lastly 3) Failed thermostat. In this section the oil filter housing gasket is the main focus. The oil filter housing is grooved for an o-ring style seal. Great design, but unfortunately these rubber o-ring gaskets have a shelf life in an extreme heat environment like this. This area of the engine can see temperatures over 250* ambient temp. The expansion and contraction of the rubber as it heat cycles, shrinks over time. When a rubber seal shrinks it will leak eventually, which is exactly what happens in this situation.
N54 WATERPUMPThe N54 use a block mounted external centrifugal electric water pump that looks sort of like a turbocharger. The power of the electric wet-rotor motor is electronically controlled by the electronic module in the pump. The electronic module is connected via the bit-serial data interface (BSD) to the ECM engine control unit. The engine control unit uses the engine load, the operating mode and the data from the temperature sensors to calculate the required cooling output. Based on this data, the engine control unit issues the corresponding command to the electric coolant pump. The electric coolant pump regulates its speed in accordance with this command. The system coolant flows through the motor of the coolant pump, thus cooling both the motor as well as the electronic module. The coolant lubricates the bearings of the electric coolant pump.
