993 injectors may be running near or at 100% duty cycle w/ the combo of 3.8 + ethanol gas
The 993 has early generation, no longer used, "EV1" pintle orifice fuel injectors and I wondered if they could be changed to the later "EV6" 4 hole, spray screen orifice injectors. EV6 injectors are resistant to ethanol and are supposed to provide better atomization, lower emissions and less sensitivity to fuel pressure.
the stock 993 fuel injector has the following specs:
Bosch number 0 280 150 786 is at 15.6 ohm, 234 cc/minute, 22 lb/hour at 3 bar.
Bosch Motorsport has an injector with almost identical specs (maybe another with closer specs?):
Bosch number 0 280 155 931 is at 12 ohms, 273 cc/minute, 25 pounds/hour at 3 bar.
The Motorsport injector appears to be an interchangeable size and connector for the 993 injector.
the stock 993 injectors run near 100% duty cycle w/ @ 6800 + 3.8 + ethanol gas near sea level
