💡 What does duration mean on hydraulic roller camshafts and how does it affect street drivability?
Understanding duration helps you lock in the right profile for your build without sacrificing low end grunt.
- Wider duration keeps valves open longer for more airflow and higher peak horsepower numbers
- Moderate lobe overlap creates that idle chop while still letting exhaust pull cleanly at highway speed
- Matching duration to compression ratios and head flow ensures handy street manners until you twist the throttle
- Pairing the right profile with solid lifters and proper spring pack locks the deal for reliable mileage
