Who is CB Performance?
CB Performance is a well-established supplier and manufacturer of high-performance parts for air-cooled Volkswagen engines, as well as custom engine building. With a reputation built on decades of experience, they cater to a dedicated community of enthusiasts who demand reliability and enhanced performance from their classic vehicles. Their commitment to providing solutions for these unique engines is evident in their product development and support. As their tagline suggests, "Some say 'We can't make it here anymore'... Well, here's a list of products that proves them wrong!" This ethos underscores their dedication to keeping the air-cooled VW scene vibrant and capable of modern performance standards.
Understanding Fuel Injection Systems
Before diving into CB Performance's specific offerings, it's beneficial to understand the advantages of fuel injection over carburetion. Fuel injection systems deliver fuel directly into the intake manifold or combustion chamber with precise electronic control. This precision leads to several key benefits:
- Improved Fuel Efficiency: By delivering only the necessary amount of fuel, injection systems minimise waste, leading to better miles per gallon (MPG).
- Enhanced Power and Torque: Optimised fuel delivery across the entire RPM range can unlock more power and a broader torque band.
- Better Throttle Response: The direct and precise fuel delivery results in a more immediate and crisp response to throttle inputs.
- Cleaner Emissions: Precise fuel control allows for more efficient combustion, significantly reducing harmful exhaust emissions.
- Easier Starting and Smoother Idle: EFI systems adapt to changing conditions, ensuring easier cold starts and a more stable, smoother idle.
- Adaptability: EFI systems automatically adjust for changes in altitude, temperature, and air pressure, ensuring optimal performance in various conditions.
CB Performance's Gen4 EFI System: A Look Back
CB Performance's Gen4 EFI System was a significant offering designed to bring modern fuel injection technology to the air-cooled VW platform.
