Publisher: Veloce Publishing

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. 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. Fujifilm's raft of FinePix cams at CES are headlined by the HS50EXR, which aims to please those who love point and shoots, but aren't quite ready to make. By Rob Hosking – Choosing a camshaft is pretty simple. 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. I intend to offer insight which will help in choosing a camshaft for yourself. Fast road cams (Sports camshafts). In a perfect world, the valve . What that statement tells us is that in terms of achieving maximum engine performance, the amount of time the camshaft is either raising or lowering the valve is effectively wasted. 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? We take a look at the science behind the design of performance and racing camshafts and offer tips for finding the right cam for your car - Circle Track Magazine. Overlap promotes cylinder scavenging at high RPM's which is crucial to power production in a naturally aspirated engine. What is the camshaft, what does it do and how can it be modified. 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. Duration is the amount of time a valve is opened and is measured in crankshaft degrees. If the intake is not open for sufficiently long a time or the exhaust valves open early much of the power from the engine will be gone.
