Our Price: $532.95

R&D Pro Series injectors offer increased fuel delivery over our 525cc injectors.  The new Pro Series injectors are offered in 725cc and 1000cc flow rates.  Each set of injectors have been flow rate and voltage comp tested to insure linear accuracy and are shipped with a precision dead time (voltage compensation) chart that can be added into your aftermarket ECUís software program under battery compensations. R&D Pro Series injectors offer perfectly clean linear response performance from low idle all the way through the entire power range. R&D has tested and verified the OEM Yamaha FZR injectors to be 80 percent peaked on stock units at sea level without modifications. R&D Pro Series fuel injectors with a higher atomization spray pattern are easily capable of delivering fuel flow specifications to accommodate 400-500 horsepower!

R&D has flow rate tested the O.E.M. Yamaha FZR injectors and verified them to flow 396 cc at 43 PSI of fuel pressure, which rates them to flow 39 pounds of fuel per hour. The R&D Pro Series Fuel Injectors have been precision flow rate tested to 725cc at 43 PSI of fuel pressure, and 925cc at 70 PSI of fuel pressure, which rates them to flow as much as 92 pounds of fuel per hour. R&D fuel Injectors perform excellent, delivering precise fuel flow at fuel pressure ratings ranging from 40 to 80 PSI.  Each R&D injector set is packaged complete with all installation hardware, necessary harness interface connectors, voltage compensation chart, and instructions.

R&D Pro Series 725cc Injectors (set of 4)
Flow Rate: 725cc at 43.5 pounds of fuel pressure= 72 pounds per hour fuel flow
