Camshaft is used to regulate the amount of air that enters an engine and how much exhaust fumes exit. Fuel economy, emission regulation and overall performance are all affected by the camshaft. It is entirely possible to replace the camshaft if you are worried about your car’s performance.
The fuel intake can be multiplied greatly by enhancing the camshaft, which allows the valves to pump better. This actually has a name, called the came profile. By manipulating the profile, you will be able let your car release exhaust fumes more easily. You will find that you can have several different profiles depending on what engine you have. This depends on the type of car that you have; sports cars will have several different profiles. Tuning companies will be able to look at your car and tell you what your cam profile options are.
There are different camshafts that are right for different cars; for example, rally-style vw camshafts are a good fit for race cars. It will be hard to drive at lower speeds if you put a supped-up camshaft on your car. Camshafts are often labeled to designate what type of performance you get, like ’rally’ or ’fast road’. The labels correlate to the performance of your engine after the camshaft is installed. Camshafts that are used for racing will have longer opening duration then others.
Higher lift of the valves comes with installing cams for race cars, but may also require additional modifications. When installing a camshaft you change to performance of your engine, like changing the spring height that allows the valve to move up and down. This has to be monitored, because spring binding (when the springs hit each other) may occur. The money you spend when dealing with this problem well help you in the long run. You may also have to swap out your valves because they could easily hit the pistons.
