The ProCharger kit comes with 39 lb injectors
The ProCharger kit is a popular choice for those looking to increase their engine's performance. The 39 lb injectors are a good option for those seeking more power, but there are also more powerful injectors available on the market. Some people opt for 50, 52, or even 60 lb injectors to really maximise their engine's potential.
It is important to note that the size of the injectors is just one factor in achieving the desired performance. The fuel pump, for example, also plays a crucial role. It needs to be able to deliver enough fuel to match the capacity of the injectors.
Additionally, the ProCharger kit is known for its ease of installation and the support provided by the manufacturer. It is a self-contained kit, which means that it comes with all the necessary components for a successful installation. This includes not only the injectors but also a programmer with a tune and cooler.
Overall, the ProCharger kit with 39 lb injectors is a great option for those seeking more power and performance from their engine. It offers a good balance between cost and performance, and with the right supporting modifications, it can help take your engine to the next level.

Some kits include 50 lb/hr fuel injectors
Some ProCharger kits include 50 lb/hr fuel injectors. For example, the 11-14 ProCharger Stage 2 kit comes with 50 lb injectors, although some sources suggest that these are actually 47 lb injectors. The ProCharger Stage 2 kit is also available with 52 lb injectors.
ProCharger kits are available with a range of different fuel injectors. Some kits come with 39 lb injectors, while others have 60 lb/hr injectors. It is also possible to purchase a ProCharger kit without injectors and then source your own.
The size of the fuel injectors you need will depend on your engine and the amount of boost you want to achieve. If you are planning on boosting your engine, it is recommended to use a 255 pump and 42-60 lb injectors. However, it is important to remember that you will also need to upgrade your fuel pump if it is stock.
Upgrading to larger injectors can provide more fuel to work with and allow for more power. However, it is important to consider the pressure from the blower on the injectors, as this will affect the effective fuel pressure.

Ford Racing LU47 injectors are 47 lb at standard 43.5 psi
The Ford Racing LU47 injectors are high-flow fuel injectors that offer a flow rate of 47 lb/hr at a delta pressure of 43.5 psi. They are designed for performance applications and are compatible with a range of vehicles, including the 2011+ Mustang, 2011-2014 Mustang, and 2011-2014 Raptor 6.2L. These injectors are also known to be included in some ProCharger kits, although there is conflicting information on the exact specifications of the injectors provided.
The LU47 injectors are sold as a set of 8 and feature a long length and USCAR electrical connector. They are designed to work optimally with air meters with revised calibrations and have been trimmed for high-flow rates. The injectors are rated at different psi levels, which can lead to varying interpretations of their capacity. For example, at a higher psi, a 47 lb injector could be considered a 50 lb or even a 52 lb injector.
The Ford Racing LU47 injectors are optimised for 5.0L Coyote cylinder heads and are compatible with all gas engines thanks to their dual cone spray pattern. They are also known to be included in some supercharger kits for the 5.0L Mustang, such as the M-6066-MGT525D, M-6066-MGT525PD, M-6066-MGT624D, and M-6066-MGT624PD models. These injectors are a direct replacement for the 2011-2014 Mustang, providing an extra range on the fuel system and capable of delivering over 600 HP.
It is important to note that injector flow rates are sensitive to pressure changes. Therefore, when referring to the flow rate, it is essential to consider the delta pressure at which the rate is quoted. In this case, the quoted flow rate of 47 lb/hr for the Ford Racing LU47 injectors is specified at a delta pressure of 43.5 psi. To convert the flow rate to a different delta pressure, multiplication by a factor of 1.054 is required. For example, at a delta pressure of 39.15 psi, the flow rate would be lower and would need to be adjusted accordingly.

DeatschWerks 65 lb/hr injectors can be used with the stock fuel pump
DeatschWerks is a company that manufactures fuel injectors and fuel pumps for a wide range of vehicles. They have been in business since 2004 and offer fuel injectors in over 250 applications and sizes for modern muscle and tuner cars. DeatschWerks 65 lb/hr injectors are high-performance fuel injectors that can be used with a stock fuel pump to achieve significant power gains.
One example of their application is in the Chevy SS, where a user reported installing a ProCharger kit with DeatschWerks 65 lb/hr fuel injectors and the stock fuel pump, resulting in a dyno of 650 HP. This setup required a Camaro ZL1 flash to be performed on the fuel pump control module. It is worth noting that the user also mentioned that the D1SC setup is for those seeking a substantial boost, and while 650 HP was the target, the resulting power was considered a "safe" tune.
Additionally, when considering fuel injectors for a supercharger setup, it is essential to match the injector size with the desired horsepower. Fuel Injector Clinic offers a Horsepower Calculator that helps determine the required injector size for a specific horsepower level. In some cases, it may be necessary to increase fuel pressure or upgrade the injectors to achieve the desired horsepower.
For instance, in a Mustang forum, users discussed the injector size required for a supercharger setup. It was recommended that for boost, a 255 pump and injectors ranging from 42-60 lb are suitable. It is also important to consider the fuel pump's capacity when upgrading injectors, as the stock fuel pump may need an upgrade to handle the increased fuel demand.
In summary, DeatschWerks 65 lb/hr injectors are high-performance fuel injectors compatible with a stock fuel pump, as evidenced by their successful application in the Chevy SS ProCharger kit. However, it is crucial to consider the specific vehicle and desired horsepower when selecting the appropriate injector size and fuel pump combination.
