How do I identify a comp cam?
COMP Cams uses two-number designations for all its engine families. The LS engine is designated 54 and this number is generally the first two numbers that define the actual cam part number. Other examples include small block Chevys -12, big block Chevys -11, and 5.0L small block Fords -35.
Are COMP Cams hardened?
Tool Steel Lifters from COMP Cams® are engineered from M2-grade Tool Steel for its hardness and ability to resist abrasion.
What are COMP Cams made out of?
There are castings and there’s billet or steel. A vast majority of our cams are made out of 5160, but we have a very good number of cams that are made out of 8620, tool steel, M4 9310, and then the cast flavors.” COMP maintains an inventory in the tens of millions worth of camshafts.
How do you read a CAM card?
Reading a Cam Card: Lobe Separation Angle (LSA)
This figure is derived by adding the intake center line plus the exhaust center line and dividing by two. In this case: 108 + 116 = 224 degrees / 2 = 112 degrees.
What is the best material for camshafts?
chilled cast iron
The most widely used material for camshafts at present is chilled cast iron ((1) in Table 5.2), using a high-Cr cast iron.
What do the numbers mean on camshafts?
The are two measurements, duration and valve lift. The duration of measured in degrees ex 278, 288 like you gave. This measures how long the valve will stay open. For example, 278 degrees of rotation of the roller the valve will be closed. The other 82 degrees of rotation is where the valve will be open.
How long does it take to break in a camshaft?
Prior to installation:
The most critical time in the life of a flat tappet camshaft is the first 20 minutes of break in, during which time the bottoms of the tappets mate-in with the cam lobes. This is true for both hydraulic and mechanical flat tappet camshafts.
What causes a cam to go flat?
The failure is usually attributed to one (or more) of the following: insufficient lubrication, improper break-in, reusing old/worn components, mechanical interferences, and inferior hardware/hardware not torqued to spec. Always use the camshaft moly paste that is included with your flat tappet camshaft set.
How much horsepower does a Thumpr cam add?
The Thumpr made the highest peak torque, the highest average torque, the highest overall average power, the best average numbers between 2,500 and 4,500 rpm, and the best numbers from 4,500 to 6,500 rpm. It made 396 hp at 5,900 and 418 lb-ft at 4,200 with the Vortec heads.
Is a hydraulic roller cam better than a flat tappet cam?
The big advantage roller cams have over their flat-tappet cousins isn’t the reduced friction most people immediately think of, it’s increased tappet velocity (i.e., faster ramp rates). This increased velocity, as much as 30 percent, equates to more power.
What is a good camshaft duration?
Performance cams typically have durations ranging from 220 up to 280 degrees or more. The longer the duration, the rougher the idle and the higher the cam’s power range on the rpm scale. A cam with a duration of 240 degrees of higher will typically produce the most power from 3,500 to 7,000 rpm.
What does a cam card tell you?
This is the number of crankshaft degrees of separation between the intake and exhaust lobe center lines. On this cam card, you will see the LSA is 112 degrees. This figure is derived by adding the intake center line plus the exhaust center line and dividing by two.
Are camshafts forged or cast?
Camshafts in piston engines are usually made from steel or cast iron, and the shape of the cams greatly affects the engine’s characteristics.
Are camshafts heat treated?
Induction heat treatment is a common method for heat treating different automotive components, including camshafts, which belong to the group of critical engine/powertrain components.
What gives a cam a choppy idle?
LSA (lobe separation angle) determines the choppiness, it has to do with the overlap of when both valves are open, as in when the exhaust valve is closing and the intake valve is opening to pull fresh fuel in on the intake stroke after pushing out the burnt fuel. Most GM cams come on a 112, 114 or 116 LSA.
Does a cam 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.
What oil should I use to break-in a camshaft?
The best oil to use during cam break-in is one with high ZDDP levels but very low or no detergent. This way, the ZDDP remains on the cam lobe and bottom of the lifter where it belongs, minimizing excessive wear and allowing the lobe and lifter interface to create the necessary wear pattern.
How do you run in a new camshaft?
Better Engine Building: Best Tips for Breaking in a New Camshaft
How long should a camshaft last?
The camshaft seal is made to last for around 80,000 miles but in some cases, it will wear out prematurely due to damage to the camshaft. The heat that the engine produces can lead to the seal becoming damaged over time.
What can damage a camshaft?
Common Causes of Camshaft Failure
- INSUFFICIENT LUBRICATION. Always use the camshaft moly paste that is included with your flat tappet camshaft set.
- IMPROPER BREAK-IN.
- REUSING OLD/WORN COMPONENTS.
- MECHANICAL INTERFERENCES.
- INFERIOR HARDWARE/HARDWARE NOT TORQUED TO SPEC.
How much lift does a thumper cam have?
It is a serious street/race cam that needs a minimum of 10.5:1 compression and a 3,200-rpm stall converter. It has a duration of 243/251 at . 050-inch lift, . 560/.
What does putting a bigger cam do?
A bigger cam will open the intake valve wider, allowing more fuel and air into the cylinder. The larger the cam, the more fuel that is let in.
