Custom Fiveomotorsport, Newest Technology EV14, 550cc/min High-Performance Fuel Injectors

  • Flow Matched Sets complete with all new o-rings read to install
  • USCAR electrical connector fittings

  • LIST PRICE IS PER SINGLE (1) FUEL INJECTOR WITH VITON O-RINGS.

FIVEOMOTORSPORT FUEL INJECTORS are custom-manufactured in small-quantity batches to achieve the highest quality product. Our injectors are all-fuels rated; including gasoline (MTBE), and E-85. The finished injectors are then flowed and inscribed with a control number. Data is recorded for each injector. The fuel injectors are then grouped into matched sets ready for shipping.

FLOW CHART: Each set is sold with a complete and unique flow-data chart indicating individual static flow rates at 3.0, 3.5, and 4.0 BAR. As well as 3.0 BAR dynamic pulse testing for idle (15% duty-cycle) and 50% duty-cycle. Along with a complete dead time off-set (latency) table. Flow matching was done with industry-standard equipment of the highest quality.
The tests were performed at varying temperatures to achieve realistic results. Linear tuning with excellent low-end, and idle rpm.
Fiveo is the only fuel injector seller that can claim this level of technology.

SPECIAL NOTE TO OUR E85 USERS:
Ethanol based fuels tend to "dry" the fuel injector outlet orifices. Customers should be made aware that this may cause a "sticking" problem in fuel injectors that sit idle for a prolonged period of time. It is suggested for applications running high ethanol content based fuels, to periodically incorporate into their fuel-system-maintenance a drop of light petroleum-based lubricant for each fuel injector. This is also considered to be good maintenance, but not essential, for stainless steel based (Black-Ops Series) fuel injectors.  It should also be noted that for optimum performance the entire fuel system should be made up of ethanol approved materials including all fuel lines/fuel pump/fuel filter, etc.


Flow rates:
(These are true and tested flow rates of this individual set of fuel injectors. We test our equipment once an hour throughout the day of the actual flow tests. We use the Bosch 0280155968 Green Giant 42lb fuel injector for our test basis.
We use Heptane as our testing agent). 
52 lbs/hr, 550cc/min at  43.5 psi (3.0 bar)
57 lbs/hr, 600cc/min at 50.0 psi (3.5 bar)
62 lbs/hr, 649cc/min at 58.0 psi (4.0 bar)
Dead Time (latency): 0.455 ms at 14 volts

High resistance, no inline resistors or resistor box requires for use.
All New-Generation EV14 fuel injectors will function at rail pressures in excess of 101 psi, 7 bar.

Excellent low pulse width response with predictable response down to 2ms.
Excellent atomization for modern multi-valve engines.
This set will require no more than a 1% trim for easy tuning.
