What Role Does Camshaft Overlap have on Engine Performance?
Camshaft overlap depends on the camshaft design. You can adjust it by changing the timing of the camshaft to the crankshaft. It is an essential factor in engine performance and can significantly impact the engine’s power output and fuel efficiency.
There are several benefits to camshaft overlap, including:
- Improved scavenging: Overlap can enhance the scavenging effect. This process uses the momentum of exhaust gases to help draw fresh intake air into the cylinder. This can improve the engine’s power output and efficiency.
- Increased airflow: Overlap can also increase airflow into the engine, improving performance and fuel efficiency.
- Increased power: Camshaft overlap can increase the engine’s power output, particularly at high rpm. This is because the overlap helps keep higher cylinder pressures and temperatures. This can improve how efficiently the combustion process works.

However, too much camshaft overlap can have adverse effects, including increased emissions and reduced low-end torque. Balancing the overlap is essential to optimizing engine performance for the desired application carefully.
Oztrack’s cams have been custom-designed and developed over the years. They are made for us in Australia using the latest CNC Camshaft machine. These machines feature the newest technology in its ability to create unique lobe shapes. Easily more than comparable to VCM Camshafts and a close Aussie match for the Brian Tooley Racing Range.
We can also custom design any cam and manufacture to suit your application. We use Dynomation 6 and Engine Analyser Pro V3.9 for new ideas and minor adjustments.
We also have a new range of supercharger cams on offer that can be tailored for your engine compression and boost levels.
Visit our online shop for details on our products. We offer camshaft installation and Prohub Dyno Tune at Oztrack. Alternatively, we can ship the items to you.
