The original (pre-Terminator X) Holley Terminator EFI System is awesome but a bit limited in fueling capacity. The four 80-pound injectors that come from the factory are capable of fueling about 570-600 HP if you push the pressure up to 60 PSI and stretch the duty cycle to and beyond 90%. Is there a path to more horsepower on these impressive 950 CFM throttle bodies?
Yes there is. These four 205-pound-per-hour injectors (at 43 PSI) can fuel a very conservative 1220 HP (NA, Gasoline) without pushing the duty cycle. Boosted applications can look for them to support about 1000 HP on gasoline, or about 720 HP on E-85. Need more? These injectors can be operated safely to 75 PSI.
Note: These Bosch/EV14 injectors use a different injector connector than the original Terminator throttle body injectors--therefore, the injector connectors on your throttle body harness will need to be swapped. If you have the Standard Terminator EFI throttle body (not the Stealth) we recommend you upgrade your entire throttle body harness to the 558-439 Injector upgrade harness. At this time Holley does not offer a throttle body harness with the EV14 injector connectors for the Terminator Stealth throttle body, so you'll be on your own to source and swap the connectors for the Stealth throttle body.
Note: These injectors only fit the original Terminator "standard" (non-stealth) throttle bodies and are not suitable for either the original Terminator or Terminator X Stealth throttle bodies.
