The MSD 8623-MSD Crank Trigger Kit with Flying Magnet Hall-Effect 8.0 sensors is a high-performance crank trigger system designed for serious racers and enthusiasts seeking maximum ignition system accuracy and reliability. This long-lasting, trouble-free solution is suitable for various applications, including nitrous and multi-fuel systems.
The heart of this system is the flying magnet crank trigger. The eight (8) magnetically positioned sensors use a hall-effect technology to create an accurate and dependable pulse for the ignition system. These sensors are designed with a flying magnet configuration, ensuring consistent and reliable engine RPM reading even under high-RPM conditions, making it an excellent choice for high-performance applications.
The MSD 8623-MSD Crank Trigger Kit incorporates an adjustable mounting bracket for easy installation and optimal sensor positioning. This allows users to place the sensors in the ideal location for their engine configuration. Additionally, the system includes an adjustable adapter to facilitate properpulser positioning relative to the crank shield.
The kit includes all the necessary hardware, including welded 1/4" weld-in, 1/8" threaded and 3/8" threaded base bosses. It is also compatible with FAST XFI, EFI Live, Holley EFI, Motec, and other various ECUs.
With its high-resolution pulse width modulated (PWM) signal, the MSD 8623-MSD Crank Trigger Kit offers superior engine management capabilities for both fuel and ignition control systems. This kit is an essential upgrade for any enthusiast looking to optimize their engine performance and improve their engine management system's accuracy and reliability.
The MSD 8623/MSD crank trigger kit is a popular choice among performance enthusiasts for creating a reliable and efficient ignition system in high-performance applications. This kit utilizes flying magnet hall-effect sensors to generate trigger signals for ignition and fueling. In this analysis, we will outline some pros and cons to help you make an informed decision about whether to invest in this product.
Pros:1. High Precision: The MSD 8623 kit offers great precision as it relies on flying magnet hall-effect sensors, which have a faster response time and shorter minimal crankshaft rotation angle compared to traditional distributor-based systems.
2. Elimination of Distributor: This kit does away with the need for a mechanical distributor, resulting in a simpler and more reliable ignition system. Additionally, it can also simplify wiring and installation.
3. Improved Ignition Efficiency: By using a multiple-spark ignition system, this kit can offer better combustion efficiency and improved performance in high-performance applications compared to single-spark distributor systems.
4. Compatibility with Both Narrow and Wide-Band O2 Sensors: The MSD 8623 kit can be used with both narrow and wide-band O2 sensors, providing more versatility for fine-tuning your engine.
5. Adjustable Ignition Timing: The ability to adjust ignition timing using the included timing controller provides better control over the engine's performance and fine-tuning capabilities.
Cons:1. Higher Cost: Compared to traditional distributor-based ignition systems, the MSD 8623 Hall Effect Crank Trigger Kit is a more expensive option, making it a larger investment for hobbyists and enthusiasts.
2. Complex Installation: The kit's installation process may be more complex than a standard distributor system, necessitating more time, expertise, and a more significant investment in tools.
3. Requires a Fully Wired Engine Harness: The MSD 8623 kit relies on a fully wired engine harness, which can add to the desired installation time and cost.
4. Sensitive to Magnet Placement:Installation of magnets on the crankshaft must be performed accurately to ensure smooth trigger signal generation. Failure to do so may result in erratic performance or difficulty in starting the engine.
5. Not Suitable for Non-Sequential Fuel Injection Systems: Although this kit can work with multiple-spark ignition systems, it's not explicitly designed for non-sequential fuel injection systems, which may necessitate additional components or modification.
Conclusion:The MSD 8623/MSD crank trigger kit offers several advantages, including improved precision, elimination of mechanical distribution, and compatibility with both narrow and wide-band O2 sensors. However, it also comes with some challenges such as a more complex installation process, sensitivity to magnet placement, and higher cost compared to traditional distributor-based systems.
If you're looking for a more reliable, efficient, and versatile ignition system in a high-performance setup, investing in the MSD 8623 Hall Effect Crank Trigger Kit can reap significant rewards. However, consider your specific application, installation experience, and budget before deciding on this investment. If the complexity and costs outlined above seem overwhelming, alternative distributor-based ignition systems might be worth exploring.
Recommendation:For hobbyists and enthusiasts seeking a high-performance ignition system with multiple-spark capabilities, but who might not have the time, expertise, or resources to install a complex kit like the MSD 8623 Hall Effect Crank Trigger Kit, consider the following alternatives:
1. MSD 6AL2 EFI Ignition Control
2. Holley EFI lite Ignition System
3. HEI distributor systems with multiple plug wires and additional ground clearance
Each system offers multiple-spark ignition, but with varying levels of complexity, cost, and compatibility with other systems (such as O2 sensors) and applications. Weigh the pros and cons of each to determine which one aligns best with your project goals and your capabilities.
In addition, they are less prone to mechanical failure since there no wear parts. With the included high-quality timing pointer and use of a direct bolt-on, degrees balance ATI 917302 or 918852, you'll be able to adjust in precise increments required for your LS Engine. Also compatible with Moliere water pump WP333 and LSX Blocks.;. Buyer pays return shipping.
