BREAKING NEWS: GMS is now offering FREE SHIPPING + A FREE SET of BRISK SILVER RACING SPARK PLUGS with every order of XDI Fuel Injectors!
Just another way GMS is showing its dedication to helping every 6th Gen. Camaro reach it's full potential, in order to leave as many Mustangs and Hellcats in their dust.
As you know, High-Flowing Fuel Injectors are a major component to High HP builds on a Direct Injected platform like the LT4. Although there are several manufactures to choose from, you can always count on Griffin-Motorsports carrying the highest quality and most trusted products on the market. Which is why we only offer XDI Fuel Injectors. Built upon the foundation of the original GM LT4 injector, they provide a straightforward drop-in installation with minimal adjustments to existing ECU injector characteristics. Each injector undergoes meticulous testing at 100bar and 200bar on OEM equipment at XDI, ensuring precise flow matching within ±0.5% for consistent performance. Tested on fully instrumented engines for superior cylinder distribution and stability at pressures up to 2800psi, these injectors are fully E85 compatible, making them a versatile choice for performance enthusiasts.
For those who may not know… XDI’s success on many DI platforms could not have been possible without its founder, Uwe Ostmann’s 25 extensive years in motorsports and DI development. Uwe’s journey started in 2001 when he joined the talented team at Bosch Germany in August 2001. Use spent many of those early years developing Diesel High Pressure Nozzles and overcame many challenges related to tuning a common rail based high pressure fuel system.
After leading the Audi Le Mans LMP1 project for four years including fuel system and controls development and developing several key technologies at Bosch Motorsport in Germany, Uwe came to Bosch Motorsport USA in July 2012.
With Uwe’s talent and determination it didn’t take long before he took over the fuel system development of all OEM race projects based on GDI systems, including the Corvette C7.R, the Ford Daytona Prototype 3.5 EcoBoost and some others that cannot be mentioned in detail. He played a vital role in developing advanced combustion analysis systems and custom fuel systems and controls for several research projects with high pressure fuel systems up to 500bar / 7250psi.
In December 2014 Uwe quit Bosch Motorsport to create XDI. The first and only Bosch Motorsport Dealer and aftermarket supplier in the world with focus on high pressure GDI race projects. Since then Uwe has continued to grow XDI’s technology, effectiveness, and product line to not only support several race programs, on wheels and on water, endurance, drift and drag… but even more importantly… your street car!
Specifications
Static Flow Rate: 30.1 g/sec (2600cc/min @ 100bar)
Max Rail Pressure:193bar / 2800psi
Fuel Compatibility: all known fuels, all Ethanol blends
Electric Connector: Bosch EV1
Driver Profile: XDI, tuning changes needed
Tuning Support: Standalone, HPT, MoTeC
Idle Stability: 0.8 ms at 20 bar
Static Flow Reference: 10 ms at 100 bar
WOT Performance and Stability: 6 ms at 200 bar
Tuning Support: Compatible with HP Tuners and standalone ECUs. Note:Due to the LT4 +70% Injectors large size, these injectors may not deliver stock-like drivability, especially on pump gas. Manual transmission cars may experience pressure overshoots after shifting, potentially causing misfires. Reducing pressure may be necessary.
Requirements
Power Potential and Recommended Combinations (LT4 +70%)
1,000 WHP on E50-E85: Use with minimum +32% cam lobe + High Flow HPFP + Dual Pump Low-Side.
1,400 WHP on Pump Gas: Use with minimum +32% cam lobe + High Flow HPFP + Dual Pump Low-Side.
Applications
•High horsepower GM Gen V V8 and V6 direct injection engines including LT4, LT1, L86, L83 and LV3
•E85 conversions of GM Gen V V8 and V6 engines
•2014-2019 C7 Corvette (LT1)
•2015-2019 C7 Z06 Corvette (LT4)
•2016-2022 Camaro SS (LT1)
•2016-2019 CTS-V (LT4)
•2020-2024 CT5-V Black Wing (LT4)
•2017-2023 ZL1 Camaro (LT4)
•2014-2023 Silverado and Sierra with 4.3L LV3, 5.3L L83 and 6.2L L86 engines Not compatible with 6mm shaft injectors
•2015-2023 Suburban, Tahoe, Yukon and Escalade with 5.3L L83 and 6.2L L86 engines Not compatible with 6mm shaft injector
For Higher Output Applications
XDI LT4 +70% Injectors are recommended for naturally aspirated (e.g., Nitro-Methane), low-RPM turbo applications, or centrifugal superchargers when combined with the LPE Big Bore pump or Katech Goliath.Important: The LPE Big Bore + LT4 +70% injectors will not meet fueling demands for setups with a 2650 TVS or Whipple blower on straight E85. In these cases, we recommend the XFP3200 + 70% injectors or supplemental fueling (methanol, PFI) around peak torque.
*Global B ECUs may require extra tuning on a case-by-case basis as we learn more about new models. We do not accept returns due to tuning difficulties, but we’re happy to assist with any technical inquiries.
All performance figures are estimates only, assume a fully supported setup, and competent tuner who has experience tuning XDI products. Your results will vary. Final rail pressure should be determined by your tuner. Injectors are non-returnable.
Product may ship direct from XDI.
What YOU will need to provide:
Patience and attention to detail for installation... or, someone like that, who you trust with your beloved, adorned, magnificent, earth shaking, alarm sounding LT4 powered beast! If you are doing this DIY (which is not that bad) be sure to get an extra set of hands. These superchargers are alot heavier than some imagine.
We strongly suggest upgrading your cooling system while the blower is out of the car because alot of the labor needed to upgrade is already done with the coolant system bleed and blower out of the car. Email us at info@griffin-motorsports.com to discuss your particular set up if you need help, or want to discuss options.
Although many people have had luck reusing the GM supercharger bolts, Fuel Feed Pipe, and Fuel Crossover Pipe, we strongly suggest you add these items to your cart, as these are ALL one time use only parts.
This package will require tuning. Email us at info@griffin-motorsports.com if you need a recommendation for a remote tuner.
