Individuals who work in highly competitive, high-pressure fields such as sports, performing arts and law enforcement sometimes turn to performance psychology to learn to achieve optimum performance. Performance psychology is a subset of sports psychology that focuses on psychomotor performance -- the mind and the body working together at peak levels. Business executives and other team leaders also employ performance psychology as a tool for success. Salary surveys track earnings of psychologists, most of whom have PhDs.
As the miles pile upon a vehicle, parts start wearing out or requiring adjustment. The valve train is no exception; even the advent of hydraulic lifters has failed to eradicate the potential for valve train noises --- more commonly known as "tappet noises." Several possible causes exist for tappet noise, including improperly adjusted valves, worn rocker arms, bent push rods, worn valve guides and loose rocker arm studs. If the inspection of all these parts fails, the problem likely lies in the lifters. Before partially tearing down the engine and replacing lifters, take a few other steps to quiet noisy…
The efficiency of a business often relies upon the efficiency of its employees. Business owners often spend time to evaluate employees in order to make sure that their workforce is reaching its potential. While it seems possible to focus most of this attention on nonperforming employees, it's also important to document the performance of high-performing workers. This kind of research allows you to reward employees who deserve a bonus while identifying potential problem areas in your business, allowing you to fix them.
Some engine manufacturers such as General Motors and Cummins make essentially the same engine for both land and marine applications, yet marine engines are more expensive. Subsequently, it's tempting to use automotive parts on marine engines and it's sometimes possible. You have to be careful, though. Not all marine engine parts are the same. Variations tend to arise in few main areas.
One tool that every home mechanic needs is a quality set of jack stands; these are designed to support a vehicle after it has been raised with the jack. An automotive jack is designed for lifting and lowering only,.and should never be relied upon to support the vehicle. Jack stands allow you to remove the jack from under the vehicle, freeing up space for you to work.
The Z34 was a sport version of the Chevrolet Lumina produced between 1991 and 1994. The Z34 replaced the Monte Carlo as Chevrolet's mid-size sport coupe, and it would occupy that spot in the manufacturer's product line until the Monte Carlo returned in 1995. Fewer than 110,000 Z34's were sold over the model's four-year lifespan.
Tappet noises can be the result of a few different problems. Sometimes the problem stems from a worn cam lobe or a bent pushrod. Improper tappet adjustments, as well as physically damaged lifter bodies are also culprits. Many technicians agree that one of the leading causes of valve train noises are sticky valve lifters caused by sludge, resulting from poor maintenance. Cleaning sticky valve lifters is not a difficult thing to do after removing them from the engine.
Track days are events where car and motorcycle enthusiasts meet up and drive or race on a given track or circuit. These events happen around the world and require a high level of preparation and maintenance to ensure safe racing. Track days allow you to explore the limits of your car's handling; they can be fun as long as it is done with due preparation and in relative safety.
Although valve lifters do not often go bad, sometimes they do fail and need replacement. When a lifter does fail, the replacement lifter must be properly prepared and pre-load tested before being put into service. Following the proper procedures to test and prepare a brand-new lifter prior to normal operation is required to validate the warranty by most lifter manufacturers. Proper lifter preparation will not only help prevent lifter or camshaft failure in the first few minutes of operation, it will ensure countless hours of dependable valve lifter performance.
Reinstalling lifters in a V-8 engine is not overwhelming, but you do need to remove the intake manifold, valve covers rocker arms, pushrods and lifters before the V-8 lifters can be reinstalled. Although most technicians agree that reinstalling the lifters themselves is a straightforward job, certain tasks and tests need to be performed before the lifters in a V-8 can be reinstalled. Disassembling the engine to this level means a problem exists in the valve train.

These mechanisms include idle screws, float adjustment screws and jets mounted on the metering block, accessible after removing four screws on the fuel bowl.
Superchargers and turbochargers are essentially pumps that force air into another air pump equivalent to the engine. All else being equal, two superchargers that are equally efficient at compressing air at a given RPM and consume the same amount of power to turn will make identical power on a given engine. There's no x-factor when it comes to supercharger sizing; it's all a matter of balancing variables and choosing a supercharger size and design that will operate best at the intended RPM.
The Chevrolet small block V-8 engine has gone through dozens of incarnations over the years. Throttle body injection served as a halfway point transition between traditional carburetors and the multipoint injection systems used today.
The Focus is a compact economy car introduced in 1999 as a 2000 model in North America by Ford Motor Co.

The hydraulic lifters in your car or truck's engine are an essential part of your vehicle. The lifters move up and down inside the block, helping generate the compression and power your car needs to run. If a lifter fails, your car or truck will not run properly and may exhibit any of several different side effects. Lifter problems cannot be repaired without rebuilding or replacing the engine on your vehicle, and such problems are typically caused by running the vehicle low on oil or overheating the engine.
Never install used hydraulic lifters on a used camshaft unless they are to be installed in the same location as they were removed from. If the location is unclear, replace them. All the camshaft manufacturers require new lifters on their camshafts to retain the warranty. Lifters gain a wear pattern as soon as the engine is started. This wear pattern may not be detectable by sight, but it is there and enough to degrade a new cam lobe. The cam lobe determines when, how far, and how long the valve is open. The more wear on the lobe the lower…
The throttle body injector (TBI) of a vehicle helps control the throttle and maintain the minimum revolutions per minute, or rpm. General Motors vehicles use the TBI in the same manner as most automobiles. To adjust the throttle position sensor (TPS) of the TBI, you must remove the TBI and alter its makeup slightly. Turning the TPS down may help improve the way your vehicle runs, but if you turn it too low, your vehicle may not start. Adjusting the TBI requires precise movements and should only be attempted by someone familiar with GM engines.

A solenoid is part of the starter on both boats and cars. It serves as a high current relay that closes main contacts in order to supply the starter motor with current. Some solenoids also act mechanically to activate a shift or lever that engages the starter motor, which then turns the engine. The two simple circuit wires in a solenoid require battery power on one and ground on the other.
Every car needs a good amount of attention and maintenance to keep it running smoothly. Oil plays a major role in this required maintenance. Car engines with flat tappet camshafts require special attention. These engines require an element known as zinc dialkyldithiophosphate (ZDDP) to prevent the engine from wearing down quickly. Due to this zinc requirement, you must select oil for this type of engine carefully.
The Toyota Yaris has been on the US market since 2007. Compact and economical, the Yaris offers low cost motoring and excellent reliability. As reliable as the Yaris is, some drivers may wish to make performance enhancements to further improve their driving experience. One area that has room for improvement is the handling.
Modern automotive engines typically use between two and five valves per engine cylinder. Lifters, also known as valve lifters or tappets, are components of an engine whose function is to open and close the valves.
Hydraulic valve lifters use oil pressure and a spring to keep the intake and exhaust valve opening and closing properly. The interior of the lifter body has a small pump shaft, oil hole and spring that actuates when the rocker arm comes in contact with it. Worn lifters or lifters that have accumulated air into their interiors, can not hold the proper opening and closing pressure. Vehicles that have excessive tappet noise can be the result of air in the lifter body. Purging the air from hydraulic lifters requires the removal of the lifters from the engine block, and the…

Like all ATVs, there are certain tips and tricks you can use when riding your Polaris trail boss that will make operating the vehicle even more fun and functional.
Hydraulic lifters act a cushions to quiet the engine as the valves open and close. When they fail to do their job, the engine has a ticking noise that is often much louder at idle than when the engine is operating at higher speeds. Increased oil pressure, made higher by the oil pump running faster with the increased engine speed, pumps more oil into the lifter, making it quieter. When the engine drops in speed, the oil pressure drops as well and the lifter is noisy once again.
Cylinder-head porting is the burring down the exhaust ports and intake of an internal combustion engine so that air flows through more smoothly. Porting brings the engine to maximum efficiency and is necessary for high-power output of modern engines, such as in racing vehicles. Most porting tips are made of carbide or another heavy-duty metal.

It is well known in automotive circles that vehicle suspensions with left and right side leaf springs do not handle as well as vehicles with trailing link, fully independent or McPherson strut suspensions. While part of this behavior lies in the nature of the springs, it is really the solid tube structure of the rear drive axle that causes unpredictable slide-outs, wheel hops and swerves that can occur on tightly winding roads. Yet it is possible to improve the handling of these vehicles significantly with nominal compromise in riding comfort.
The staggering of wheel and tire packages is one of the most basic forms of vehicle tuning, and plays a huge role in all aspects of vehicle dynamics from steering response to acceleration.
The struts on your car are designed to control the rebound of the springs every time you go over an irregular road surface. This happens very frequently while driving, which causes the struts to wear, after several thousand cycles of compressing and rebounding. When this happens, the struts lose their ability to control the rebound of the spring, creating a bouncy and uncomfortable ride. Worn struts can also increase braking times because the vehicle's inertia is transferred to the front during braking, possibly lifting the rear wheels off the ground slightly and reducing or eliminating their braking ability.
The torque-to-horsepower bias of any car's engine is one of its defining traits, and contributes a lot to the character of the vehicle. Preference for either torque or horsepower is dependent on a number of factors, including vehicle weight and intended performance.
Without question, the 350 is General Motor's most popular small-block engine, both for street and high-performance applications. First produced in 1968, the 350 featured a surprising amount of power for its size. However, the 350 can be made to produce substantially more power than it did from the factory. The key to building horsepower with the 350 is improving its restrictive stock fuel delivery and exhaust systems. Parts selection is critical, so always consult the various manufacturers to determine which type of component is best for the engine's intended purpose.
Solenoid switches are used to switch high power circuits on and off using a much smaller electrical control signal to actuate the switching. This allows extensive logic and decision making circuitry to be performed on inexpensive microchips and small electronic parts, with the actual switching of the high power signals being limited to the very last step. The result is cooler running of less sophisticated equipment. It also enables the high power switching equipment to be limited to a remote location. Solenoid switches are typically used on automotive engine starting systems.
An oil hydraulic flow divider is a broad term which can mean a number of things, all pertaining to a pressurized oil system. Such systems might be found in high-performance racing vehicles or airplane engines. Essentially, an oil hydraulic flow divider's job is to split a given amount of pressurized oil between multiple destinations; like multiple crank-cases for example. They can be as simple as a T-shaped pipe junction, but this is only effective in dividing the flow of oil equally between two destinations. When a specific ratio of oil is needed, a proportional valve or a proportional solenoid is…
