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.

Ethanol based fuels tend to "dry" the fuel injector outlet orifices.
Users/tuners 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.
