Maximum Rail Pressure: 221bar / 3200psi
Fuel Compatibility: all known fuels, all Ethanol blends
Electric Connector: Bosch EV1
Driver Profile: XDI, tuning changes needed
Static Flow Rate: 23 g/sec (2000cc/min @ 100bar)
Tuning Support: Standalone, HPT, MoTeC
- Flow Rates:
- 2000 cc/min at 100 bar
- 3000 cc/min at 200 bar
- Performance: Rock-solid, perfectly linear
- Fitment: 100% drop-in with OEM spray pattern
- Cold Start & Idle: Stock-like cold start and idle, with only one ECU value change required
- Increased Flow:
- 50% more flow than production LT1/L86 injectors (15.3 g/sec)
- 30% more flow than production LT4 injectors (17.7 g/sec)
- Tuning: Custom tuning required
Injector Testing and Documentation:
Each XDI injector set is rigorously tested and matched at three critical operating points, with full documentation provided:
- 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
Combinations and Power Potential (LT4 +30%):
Perfect for 750-850whp on E85, if combined with a minimum +32% cam lobe for the LT4 OEM-HPFP (up to 3200psi) or the LPE HPFP.
Good for 1000whp on blends or race gas with turbos, if combined with a minimum +32% cam lobe for the LT4 OEM-HPFP (up to 3200psi) or the LPE HPFP.
Good for 1000whp applications on full E85 (TVS2650, Whipple, F1A) if combined with a minimum +32% cam lobe for the LT4 OEM-HPFP (up to 3200psi) or the LPE HPFP and meth injection.
Good for 1000whp applications on full E85 (TVS2650, Whipple, F1A) in combination with our XFP3200 belt driven fuel pump.
Good for 1200whp on race gas with turbos in combination with our XFP3600 belt driven fuel pump.
For higher output applications our brand new XDI LT4+65% DI Fuel Injectors are available.
These work good with the LPE big bore pump on NA (e.g. Nitro-Methane), Turbo (low boost at low rpm) or centrifugal superchargers.
The LPE Big Bore + LT4+65% Injectors WILL NOT BE ENOUGH in combination with a 2650 TVS or Whipple blower !!!
You will be PUMP LIMITED on these combos especially using E85. The 65% injectors do not help over the 30% injectors in this combination.
We would recommend our XFP3200 + 65% injectors, or as a band aid heavy supplemental fueling around peak torque (meth, pfi).
Tuning Support: HPT, standalone ECU
