TECH QUICKIE: Camshaft Lobe Separation Angle And Power Relationship Selecting a camshaft for a given engine’s purpose usually involves a compromise between low- or high-end power options, and the lobe separation angle (LSA) is one of those factors where engine builders have to make a choice between those priorities
Lobe Separation Angle Explained and How it Affects Horsepower According to the Comp Cams catalog, "The lobe separation angle (LSA) is equal to 1 2 the angle in crankshaft degrees of rotation between the maximum exhaust valve lift and maximum intake lift "
Lobe Separation and idle characteristics - Hot Rod Forum For example, an LSA of 104-107 will be a very rough, choppy idle 108-110 LSA will be a moderate racey lope, and 111-114 LSA will have a slight lope but a relatively smooth idle The more detailed question would be, would a cam with 400" lift and another with 600" lift idle about the same if both were ground on the same (use 108 for example) LSA?
What is Camshaft Lobe Separation? · Help Center The Lobe Separation Angle (LSA) is the distance between the centerlines of the intake and exhaust lobes on the camshaft It is measured in degrees of camshaft rotation
Unlock the Secrets of Camshaft LSA: The Ultimate Guide Camshaft lobe separation angle (LSA) is a crucial parameter that determines the timing and duration of valve events in an internal combustion engine It represents the angular difference between the intake and exhaust camshaft lobes for a specific cylinder
Camshaft Lobe Separation Angle | Classic Car Restoration Club The lobe separation angle or LSA is the angle in camshaft degrees between the maximum lift points, or centerlines, of the intake and exhaust lobes It affects the amount of valve overlap; that is the brief period of time when both the intake and exhaust valves are open
Camshaft LSA specs vs. ICL: | Team Chevelle LSA is expressed in terms of the camshaft angles between the lobe peaks ICL is expressed in terms of crankshaft angle between TDC and the intake lobe peak The divide by 2 comes from the crank spinning twice as fast Also, when you degree things, the wheel is on the crank
