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.
