Cam lobe separation is the angle in degrees between maximum lift of a pair of cam lobes. To picture cam lobe separation a little better, look at the end of a traditional V8 camshaft. Draw a line through the center of the cam out through the point of maximum lift on each cam lobe on a pair of lobes. You'll usually find the measurement between. Valve overlap is mostly a function of duration and lobe separation angle (LSA), and to some minor degree valve lift. If the LSA remains the same but you increase the duration, the amount of overlap will also increase. Overlap is the span (measured in crankshaft degrees) when the exhaust valve and intake valve are both open. 14,453. ohio. The 114 cam will give more low end torque, good midrange, less power up high. And better gas mileage. Good cam for a lower rpm street engine. Pretty much standard for an RV type cam. The 110 is probably a better choice for a performance street engine. Aug 20, 2006. The Lobe Separation Angle (LSA) is the distance between the centerlines of the intake and exhaust lobes. It is expressed as degrees of camshaft rotation. It tells you where the lobes are placed on the camshaft. Follow this link for more about the Lobe Separation Angle. 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. How is it measured? You can calculate the LSA using the centerlines of the intake and exhaust lobes. (This information should be listed on your Cam Card. To check your LSA you calculate it by adding the intake and exhaust Lobe Centers together and dividing their sum by two. Example: Hotcams Stage 2 - 106.5* Intake Lobe Center + 103.5* Exhaust Lobe Center = 210 / 2 = 105* LOBE SEPARATION ANGLE). Overlap. Overlap is the degrees that both intake and exhaust valves are open at the same time. I'm guessing the cam is run straight up so the cam advance that you calculate may be the actual effective cam advance or retard. The durations and lift of the cam is not adjustable. 03-27-2009 #43. oldskool. ...

Answer: 8.4. CAM SIZE DETERMINATION Cam size determination is related to the determination of the base circle of the cam. In almost all applications we would like to minimize the size of the cam being used. Large cams are not desired due to the following reasons: 1. More space. Valve overlap is mostly a function of duration and lobe separation angle (LSA), and to some minor degree valve lift. If the LSA remains the same but you increase the duration, the amount of overlap will also increase. Overlap is the span (measured in crankshaft degrees) when the exhaust valve and intake valve are both open. nl ## bg su Lobe Separation Angle, on the other hand, is ground into the cam and it cannot be changed (see red arc in illustration). To check your LSA you calculate it by adding the intake and exhaust Lobe Centerline figures together and dividing their sum by two (Ex: 112 intake Centerline + 116 exhaust Centerline = 228 / 2 = 114-degree LOBE SEPARATION.

LSA and Lift affect the "sound" and idle quality. Generally, smaller lobe separation angles cause an engine to produce more midrange torque and high rpm power, and be more responsive, while larger lobe separation angles result in broader torque, improved idle. Choose a lobe separation angle based on displacement, valve sizing, and how the engine will be used. The smaller the valves, the tighter (fewer degrees) lobe separation should be. However, tighter lobe separation does adversely affect idle quality. This is why most camshaft manufacturers spec their cams with wider lobe separations than the.

The cam is a Crane flat tappet mechanical cam with 252/260 degrees of duration at .050-inch tappet lift with .560/.554-inch valve lift and a 112-degree lobe separation angle. The engine also employs Harland Sharp 1.5:1 roller rockers and work against a set of Crane 408 lb/in dual valvesprings with 120 pounds of seat pressure at a 1.875inch. First is you can check the exhaust lobe timing - the difference in crank degrees of the exhaust event from the intake event should be the lobe centerline angle of the camshaft times two. (114° cam angle x 2 = 228° crank angle. Second, you can check the timing of other cylinders - Cyl #6 is easy to measure, as its 360° away from Cyl #1. This is something called lobe separation angle, or lobe displacement angle. Simply put, this is the number of degrees (expressed this time in camshaft degrees) separating the intake and exhaust lobe centerlines. The easiest way to understand this is to look at the layout of the intake and exhaust lobes in the drawing. There are a couple different ways to calculate the overlap of the cam. 1) The easiest way is to add the intake opening times to the exhaust closing time. Seat ... the overlap can be calculated using the advertised duration and the Lobe Separation Angle (LSA). This formula works for both single and dual pattern cams. Add the intake and exhaust.

To check your LSA you calculate it by adding the intake and exhaust Lobe Centers together and dividing their sum by two. Example: Hotcams Stage 2 - 106.5* Intake Lobe Center + 103.5* Exhaust Lobe Center = 210 / 2 = 105* LOBE SEPARATION ANGLE). Overlap. Overlap is the degrees that both intake and exhaust valves are open at the same time. To get the air/fuel mixture in the engine and the exhaust out at high rpm, race cars need a camshaft with as much lobe lift and as many degrees of duration as possible and a narrow lobe-separation angle(LSA), which results in valve overlap. A cam like this has extremely poor idle quality the engine wont run below 2000 rpm but idle quality.

Lobe Separation Angle, on the other hand, is ground into the cam and it cannot be changed (see red arc in illustration). To check your LSA you calculate it by adding the intake and exhaust Lobe Centerline figures together and dividing their sum by two (Ex: 112 intake Centerline + 116 exhaust Centerline = 228 / 2 = 114-degree LOBE SEPARATION. The Roche lobe geometry is important to understand and study the properties of the mass-losing component in a semi-detached binary system.

My opinion is your best choice is 108 deg of lobe separation with the intake centerline in around 106 to 107deg. In the right combination 106 separation might even be better. But at 108 you will be in a good area. ditch the hydraulic roller and go to a mechanical roller with around 250 deg @ .050 on the intake.

Cam B has a duration of 240 degrees, lobe separation angle of 112 degrees, intake centerline of 110 degrees and the exhaust centerline is not published. By deducting 110 from 112, we find the value 2. By adding 2 to the lobe separation angle of 112, we can deduce that the exhaust centerline is 114. Timing events would be 10/50/54/6.
