Many people opt for an Electronic Fuel Injection (EFI) system over a carburetor due to its increased reliability. While carburetors are easier to clean and rebuild, EFI systems are more complex and require the assistance of a technician. The Edelbrock universal EFI sump kit is designed to provide the high-pressure fuel needed for EFI applications in vehicles that still use a mechanical fuel pump. In some cases, EFI is not available for your engine model, and unless you have the expertise to select individual components and build your own fuel manifold and rail configuration, carburetion is the best option.
A key difference between the two is that the EFI is constantly readjusting on the fly, while the carburetor does not. Aftermarket multiport EFI systems are the best option if you want to switch from a carburetor. However, these are more complex systems that require replacing the intake manifold and making custom adjustments on a dynamometer. When I asked Mark if the initial outlay of an EFI system would be more than just a carburetor, he told me that it's worth trading it for the overall increase in performance and consistency of performance with EFI.
Adjusting a carburetor requires hand tools, while EFI requires entering information into a portable controller. The main benefit of an EFI system over a carburetor is its increased reliability. An EFI system can adjust itself on the fly, meaning it can make adjustments to fuel delivery based on changing conditions such as temperature or altitude. This makes it much more reliable than a carburetor, which does not have this capability. Additionally, an EFI system is much more efficient than a carburetor, meaning it can deliver more power with less fuel consumption. The initial outlay for an EFI system may be more than just a carburetor, but it's worth trading it for the overall increase in performance and consistency of performance with EFI.
Additionally, an EFI system requires less maintenance than a carburetor, as it does not need to be adjusted as often. This means you can save time and money in the long run. In conclusion, an EFI system is more reliable than a carburetor due to its ability to adjust itself on the fly and its increased efficiency. It also requires less maintenance and can save you time and money in the long run. If you're looking for increased performance and reliability from your vehicle, an EFI system may be worth considering.
