What does 112 2 mean?
It means the cam’s intake lobe centerline is at 110 degrees (aka 2 degrees of built-in advance).
What does +2 mean on Cam LSA?
The + 2 or + 4 designation after the LSA is the amount of advance ground into the cam if it was installed straight up. This will effect the intake centerline like you stated.
What does LSA mean on a camshaft?
Lobe-Separation Angle
What Is Lobe-Separation Angle? LSA is the distance from the centerline of the intake lobe to the centerline of exhaust lobe. It is the average centerline between both lobes and expressed in degrees ranging from 95 on the extremely narrow/tight side to upward of 120 on the wide end.
What is ICL on a camshaft?
Intake centerline is not something ground into the cam by the manufacturers like the Lobe Seperation Angle. ICL is just a reference point of the valve events in relation of crank position. 110 ICL means the Intake valve reaches its maximum lift at 110 degrees BTDC.
What is the difference between 114 LSA and 112 LSA?
A wider LSA figure (i.e. 114) moves the lobe centerlines further apart and will smooth your idle due to the decrease in overlap that it creates. The lower the figure (i.e. 112) moves the centerlines closer and will increase bottom end power, but your idle will suffer along with it.
How do I calculate my LSA cam?
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 ANGLE).
What is Cam LCA?
The subject: camshaft lobe centerline angles, or LCAs. Notably, it is the only cam attribute described in camshaft degrees rather than crankshaft degrees. Remember, the cam runs at half engine speed, and a cam producing 300 crank degrees of “off the seat” timing has a lobe which occupies 150 degrees of cam angle.

What is lobe centerline?
First let us define the lobe centerline angle. In simplest terms it is the angle between the intake and exhaust lobe peaks. Notably, it is the only cam attribute described in camshaft degrees rather than crankshaft degrees.
What does intake centerline mean?
The intake valve reaches its maximum lift at some defined point (usually about 106 degrees) after top dead center. This is called the intake centerline, which refers to where the cam has been installed in the engine in relation to the crankshaft. This is where the engine can really build some power.
What does cam overlap mean?
Overlap is when the intake and exhaust valves are open at the same time. It is expressed in degrees of crankshaft rotation. Not all camshafts have overlap. If they do, it happens at the end of the exhaust stroke and the beginning of the intake stroke.
What is 222 spiritual meaning?
