For enthusiasts seeking to elevate their vehicle's performance, particularly in the demanding world of off-roading, the quest for a robust and adaptable fuel management system is paramount. Redline, in collaboration with Clifford Inline, a renowned leader in inline-6 engine development with half a century of expertise, presents its groundbreaking Redline 6 fuel management system. This isn't just an upgrade; it's a comprehensive transformation of your vehicle's induction system, designed to deliver exceptional torque, smooth all-terrain drivability, and significantly increased horsepower.

What is the Redline 6 System?
The Redline 6 is a master conversion kit designed to replace your vehicle's factory carburetor with a fully programmable fuel injection system. It represents a complete overhaul of the induction setup, incorporating an improved Clifford intake manifold and a high-volume, high-flow Redline throttle body. At its core, the system leverages the latest in computer technology to provide precise control over both the fuel system and ignition timing. This integrated approach ensures a total engine management upgrade, optimising not only fuel delivery but also ignition performance for a truly modernised engine.
The Need for Programmable Fuel Injection
In the realm of off-roading, vehicles are subjected to extreme conditions. Navigating challenging terrains, steep inclines, and unpredictable surfaces demands an engine that can adapt instantly. Traditional carburettor systems, while tried and tested, often struggle to maintain optimal air-fuel ratios across a wide range of angles and altitudes. Non-programmable factory injection systems, while an improvement, still present limitations. They can leave drivers wanting more in terms of fine-tuning and adaptability. This is where fully programmable fuel injection, such as the Redline 6, shines. It offers the ability to precisely tailor the fuel and ignition maps to suit specific driving conditions, ensuring maximum efficiency, power, and drivability regardless of the terrain or angle of operation. This level of control is essential for unlocking the full potential of your engine, especially when transitioning between demanding off-road trails and the requirements of street usability.
Key Features and Benefits of Redline 6
1. Comprehensive Induction System Upgrade
The Redline 6 kit is a holistic solution. It includes:
- Improved Clifford Intake Manifold: Designed to optimise airflow and fuel distribution to each cylinder, contributing to better combustion efficiency and power output.
- High Volume, High Flow Redline Throttle Body: This component ensures an unrestricted supply of air to the engine, crucial for delivering increased horsepower and responsiveness.
This integrated approach ensures that all components work in harmony to provide a substantial upgrade over the factory induction system.
2. Fully Programmable Fuel and Ignition Control
The heart of the Redline 6 system is its advanced computerised control unit. This allows for granular control over:
- Fuel Delivery: Adjust air-fuel ratios precisely for various engine loads, RPMs, and environmental conditions. This translates to improved fuel economy and optimised power delivery.
- Ignition Timing: Fine-tune ignition timing to maximise combustion efficiency, prevent knocking, and enhance overall engine performance.
The programmability means you can adapt your engine's behaviour to your specific needs, whether it's for crawling at low speeds, tackling steep inclines, or cruising on the highway.

3. Enhanced Torque and Horsepower
The combined effect of the improved intake manifold, high-flow throttle body, and precise fuel/ignition management results in a significant boost in both torque and horsepower. Drivers can expect:
- More Torque: Crucial for overcoming obstacles off-road and providing strong pulling power.
- Increased Horsepower: Essential for maintaining reasonable highway speeds and a more engaging driving experience on the road.
This performance uplift is a direct benefit of the system's ability to optimise the combustion process under all operating conditions.
4. Smooth All-Terrain Drivability
One of the most significant advantages of the Redline 6 is its ability to provide smooth and predictable engine response, even on the most challenging terrain. The precise fuel control eliminates the hesitation and stumbling often associated with carburettors when operating at extreme angles. This translates to:
- Improved Control: More confidence when navigating difficult obstacles.
- Consistent Performance: The engine behaves predictably, allowing the driver to focus on steering and throttle control.
5. Legitimate Highway Speeds
While developed with off-roading in mind, the Redline 6 system does not compromise on-road usability. It is engineered to allow for effortless travel at reasonable highway speeds. This means you can drive to your favourite trail without being limited by your vehicle's performance, enjoying a more comfortable and capable experience both on and off the beaten path. The system effectively bridges the gap between extreme off-road capability and everyday road use.
Redline 6 vs. Other Options
The market for engine upgrades is diverse, but the Redline 6 stands out due to its comprehensive nature and advanced technology. Here's a brief comparison:
| Feature | Redline 6 System | Carburettor Systems | Non-Programmable EFI |
|---|---|---|---|
| Fuel Control | Fully Programmable EFI | Mechanical | Fixed EFI |
| Ignition Control | Programmable | Distributor-based | Fixed EFI |
