B-series Camshaft Upgrades: How to Increase Power and Torque from 1500 to 7000 Rpm

by

The B-series engine, known for its reliability and performance, can be significantly enhanced with the right camshaft upgrades. Understanding how to increase power and torque from 1500 to 7000 RPM is essential for any enthusiast looking to maximize their engine’s potential.

Understanding the B-Series Engine

The B-series engines, produced by Honda, are widely recognized for their versatility and tuning potential. They are commonly found in models such as the Civic and Integra. The B-series engine family includes several variants, each with unique specifications and capabilities.

  • B16A
  • B18C
  • B20B

What is a Camshaft?

A camshaft is a crucial component in an internal combustion engine that controls the timing and duration of the valve openings. It plays a vital role in determining the engine’s performance characteristics, including power and torque output.

Benefits of Upgrading Your Camshaft

Upgrading the camshaft can lead to significant improvements in performance. Key benefits include:

  • Increased power output across a wider RPM range
  • Improved throttle response
  • Enhanced engine efficiency
  • Better overall driving experience

Choosing the Right Camshaft for B-Series Engines

When selecting a camshaft for your B-series engine, consider the following factors:

  • Intended use of the vehicle (daily driving, racing, etc.)
  • Desired power band (low-end torque vs. high-end horsepower)
  • Compatibility with existing engine components
  • Budget and brand reputation

Types of Camshaft Upgrades

There are several types of camshaft upgrades available for B-series engines:

  • Stock Replacement Camshafts
  • Performance Camshafts
  • Custom Grind Camshafts
  • Racing Camshafts

Installation Process

Installing a new camshaft requires careful attention to detail. Here’s a general overview of the installation process:

  • Gather necessary tools and components
  • Remove the engine cover and timing belt
  • Take out the old camshaft
  • Install the new camshaft
  • Reassemble the engine components
  • Adjust valve clearances if necessary

Tuning After Camshaft Upgrade

After upgrading the camshaft, tuning the engine is crucial for optimal performance. This process may involve:

  • Reprogramming the ECU
  • Adjusting fuel maps
  • Fine-tuning ignition timing

Potential Challenges

While upgrading the camshaft can yield great benefits, there are potential challenges to be aware of:

  • Increased noise levels
  • Possible loss of low-end torque
  • Need for additional modifications (e.g., upgraded valves, springs)

Conclusion

Upgrading the camshaft on a B-series engine can dramatically enhance its performance, allowing for increased power and torque from 1500 to 7000 RPM. By carefully selecting the right camshaft and following the proper installation and tuning procedures, enthusiasts can unlock the full potential of their engines.
