1200+HP Direct Injection Fueling - No Port Injection Required
Take your Gen V GM LT direct-injection system to the next level with the Stanadyne High-Performance Fueling Package.
This package combines a complete set of Stanadyne 7.5mm High-Flow Direct Injectors with the RGX 12mm High-Pressure Fuel Pump, giving high-horsepower LT applications the additional fuel capacity needed for serious boosted combinations running gasoline or E85.
Built for 1200+ HP Applications
Instead of piecing together a high-pressure fuel system, we've combined the pump and injectors we use in our own high-horsepower development into one complete package.
Whether you're running a supercharger or turbo system, the Stanadyne/RGX combination dramatically increases the capability of the factory DI system and provides the fuel headroom required for serious power.
Includes:
-
(8) Stanadyne 7.5mm High-Flow Direct Injectors (Optional)
-
(1) RGX High-Pressure Fuel Pump
-
Compatible with Gasoline & E85
-
Capable of supporting 1200+ HP combinations*
-
Retains a true direct-injection fuel system
- Ideal for supercharged and turbocharged Gen V LT applications
- Professional calibration required
Proven Power
We don't just sell this combination - we use it.
For customers pushing beyond the capabilities of the factory DI system, this package offers a proven path to significantly more fuel capacity without immediately moving to a completely different fueling strategy.
Applications
Designed for 7.5mm injector-bore Gen V GM LT applications, including compatible:
LT1 • LT2 • LT4 • L83 • L86 and other Gen V LT-based combinations
IMPORTANT: Verify injector stem/bore size before ordering. Some later GM applications use 6mm injectors rather than the 7.5mm configuration included with this package. Your existing 6mm listing similarly advises customers to verify cylinder-head injector size before ordering.
Tuning Required
Installation of high-flow direct injectors and an upgraded high-pressure fuel pump requires proper ECU calibration. Injector characterization, commanded fuel pressure and other calibration parameters must be configured appropriately for the vehicle and fuel being used.
FLHP tuning services are available for supported applications.
Horsepower Disclaimer
*1200+ HP capability is configuration dependent and should not be interpreted as a guaranteed horsepower rating. Actual fueling capacity will vary based on fuel type, commanded fuel pressure, injector window, engine combination, boost level, low-side fuel supply, calibration and other supporting modifications.
For extreme applications, contact Florida High Performance so we can help determine the appropriate fuel-system configuration for your build.
