What is a scatter camshaft?
A proper scatter cam as used in the Series-A engine, would utilize four different lobe profiles. The reason for the scatter cam profile is to move the intake/exhaust events which interfere with one another away from each other, so as to lessen the impact of the events.
What do better camshafts do?
The camshaft activates a cylinder’s intake and exhaust valves. Different camshafts will allow the vehicle to perform better under certain conditions. For example, allowing more fuel into the cylinder is wasteful at low RPMs, but provides more power at higher RPMs.
Do aftermarket camshafts increase horsepower?
Performance cams increase the duration and timing of the valve openings during the engine stroke, increasing horsepower and making your car accelerate more quickly. You’ll idle slightly rougher with a performance cam, but get a throaty rumble that’s desirable for some gearheads, depending on your vehicle.
How much horsepower does a Stage 2 cam add?
Most Stage 1 type modifications are typically in the +10-15% power increase over stock. Stage 2: this is typically referred to an engine with a performance cam upgrade as well as the other components within a Stage 1 combination. A typical Stage 2 has generally +20-25% more HP than stock.

Why does a car have a scatter Cam?
A proper scatter cam as used in the Series-A engine, would utilize four different lobe profiles. The reason for the scatter cam profile is to move the intake/exhaust events which interfere with one another away from each other, so as to lessen the impact of the events.
What do you need to know about a camshaft?
A cam… in its most generic sense converts rotary motion into linear motion or vice versa using solid egg-shaped actuators (lobes)¹. An engine camshaft… refers to the shaft which houses a series of cams that actuate the opening/closing of the intake and exhaust valves on a four-stroke engine. A performance camshaft…
When to use simpler forms of scatter Cam?
That’s a proper scatter cam. Simpler forms are used where the exhaust timing is less exotic – largely because of cost and development work.
How many cam lobes are there in a scatter Cam?
The cam lobes open the same amount. They open and close for the same duration. A dual pattern camshaft is where there are two different cam lobe profiles on the intake and exhaust sides. A proper scatter cam as used in the Series-A engine, would utilize four different lobe profiles.
