Choosing the Right Oil Flat Tappet Cam: A Buyer’s Guide
An oil flat tappet cam is a key part of your engine. It helps your engine run smoothly. This guide will help you pick the best one.
Key Features to Look For
- Lift: This is how high the valve opens. More lift usually means more air and fuel can enter the engine. This can make your engine more powerful.
- Duration: This is how long the valve stays open. Longer duration can give your engine more power at higher speeds. Shorter duration is better for low-speed driving.
- Lobe Separation Angle (LSA): This is the angle between the intake and exhaust lobes. A wider LSA makes the engine run smoother at idle. A tighter LSA can give more power.
- Intake and Exhaust Timing: This tells you when the valves open and close. Precise timing is important for engine performance.
Important Materials
The best oil flat tappet cams use strong materials. This makes them last a long time.
- Cast Iron: Many cams are made from cast iron. It is strong and affordable. Some cast iron cams have special coatings to reduce wear.
- Steel Billet: Steel billet cams are even stronger. They are often used in high-performance engines. Steel billet cams are more expensive.
- Surface Treatments: Good cams often have special coatings. These coatings help reduce friction. They also protect the cam from wear. Nitriding and induction hardening are common treatments.
Factors That Improve or Reduce Quality
Several things affect the quality of an oil flat tappet cam.
- Manufacturing Precision: A high-quality cam is made with great accuracy. The lobes must be shaped perfectly. This ensures consistent valve operation. Poorly made cams can cause engine problems.
- Heat Treatment: Proper heat treatment makes the cam very hard. This prevents the tappets from wearing down the cam lobes.
- Lubrication: The cam needs good oil. If your engine oil is old or dirty, it can damage the cam. Using the right oil is very important.
- Installation: Installing the cam correctly is crucial. If it’s not installed right, it won’t work well. It can even break.
User Experience and Use Cases
People choose oil flat tappet cams for different reasons.
- Everyday Driving: If you want your car to run smoothly every day, a mild cam is a good choice. It will improve fuel economy and make driving easier.
- Performance Upgrades: For more power, you might choose a performance cam. These cams have more lift and duration. They are great for racing or just having fun.
- Restoration Projects: If you are restoring an old car, you might need a stock replacement cam. This will keep the engine looking and running like it did when it was new.
When you buy a cam, read reviews. Ask for advice from mechanics. Choosing the right cam ensures your engine performs its best.
Frequently Asked Questions about Oil Flat Tappet Cams
