Dynamically flowed and grouped to within 1% tolerance using Racetronix custom injector flow benchwhen purchased in packs.
All tests run with n-Heptane @ 20oC (+/-1oC), 3.0 Bar (+/-0.01 Bar), 14VDC (+/-0.05VDC), saturated driver with RC cutoff.
Injector flow rates are based on testing with n-Heptane test solvent (0.6855 g/ml). U.S. EPA emission test gasoline 40CFR86.113 (0.735g/ml) flows in most common injector designs at about a 3 to 4% higher rate than n-Heptane. A ratio of 1.035:1 can be used when converting the flow specifications above.
This high-impedance injector will work with all factory ECM/PCM injector drivers.
Top feed disc injectors uses multiple holes around its circumference. The disc rests on a short chimney that surrounds a metering hole. As the disc is raised off the chimney by magnetic force, fuel flows through the holes in the disc, over the walls of the chimney, and out the metering hole to form a full, finely atomized cone.
Performance advantages over pintle injectors (i.e. Ford / Bosch & Accel types) as listed by Delphi:
Static Flow Rate: 54.9 lb/hr at 43.5 psi.
Static Flow Rate: 63.39 lb/hr at 58 psi.
