Description
Magnetti Marelli 46 lb/hr or 491 cc/min, "Silver Bullet" short racing injectors
The characteristics of the injector are a fast pulse response, high precision, high
dynamic range and optimum fuel atomisation. These are achieved by a high
performance ON-OFF actuating electromagnet with opposing expansion poles that
moves an internal injector valve on high-precision ground cylindrical slides, and a high
precision nozzle.
The injector has a stainless steel body, a fuel-resistant plastic connector, martensitic
stainless steel internal valve and an electromagnet with a low carbon content stainless
steel armature.
Static Flow Rate: 44.0 lb/hr, 491 cc/min
Dynamic Flow @ 2.5ms PW @ 100Hz: Not specified
Coil Resistance: 14.6 Ohms (nominal) (This high-impedance injector will work with all factory ECM/PCM injector drivers)
