Why the camshaft plays a vital role in making power. There's only so much space in a catalog to display the most popular cam profiles, so you can't rely on the catalog solely when selecting a cam, you really need to call our technical service rep to get accurate time-frames on availability and shipping.”. Once your RPM range is known, you will have an easy time finding some cams that may work, but how to narrow it down from there? Our mission is to serve our customers needs by offering the widest and latest selection of premium quality product at low prices while providing excellent customer service. Most cam manufacturers give you a rough idea on track size, and a set in stone RPM range to go from, so the basic homework is done by them. By Rob Hosking – Choosing a camshaft is pretty simple. Ever wonder why hotrods sound like they do at idle? But having the greatest flowing heads counts for zero if the valves are not opened sufficiently or at the right time in relation to the crankshaft's rotation, and that very important function falls to the camshaft. Overlap promotes cylinder scavenging at high RPM's which is crucial to power production in a naturally aspirated engine. If maximum torque and power along with the biggest area under the curve is the target, then only one LCA will do the job, and it has to be the one the engine wants, not one you or someone else doing your guessing for you arbitrarily decides is the one needed.

If you want to increase low-end torque to launch a heavy bike from a stop, or top-end horsepower for HARLEY-DAVIDSON CAMSgreater top speed, choosing the appropriate cam configuration will help you achieve the desired Nevertheless, these variables are critical in determining not only an engine's maximum power output but also the shape of its power curve. Which both the intake and exhaust valves are open at the same time. Stand on the gas pedal at 2500 RPM, and the phaser advances the intake cam to provide maximum power. I intend to offer insight which will help in choosing a camshaft for yourself. With so many variables and options, we asked the experts the big question: Do you need a custom camshaft to get the most out of your engine? If a cam has a 108 degree lobe centerline it means that the max lift on the Intake and exhaust is 108 degrees apart on the cam. Duration is the amount of time a valve is opened and is measured in crankshaft degrees.
