900cc Injectors Deatschwerks Volvo 240 740 940 BMW M3 (Set of 4)

Set of 4x Injectors 900cc for Volvo 240/740/940 Red Block 1985-98, BMW M3 1988-91

Fuel injectors are not a one-size-fits-all product. The right fuel injector must combine the elements of fitment, coil impedance, flow rate and tuning data. Using 450 data points from all these areas, Deatschwerks created sets of injectors matched to suit a specific engine.

The Deatschwerks’ dynamic flow-matching process ensures each set works together as a system to fuel your engine.

DW collects 450 data points on each injector and their multi-point, dynamic flow testing process mimics real-world conditions by testing at multiple pulse widths within each of the following ranges:

Low Range (1-2 milliseconds)
Low pulse widths are used during idle, light throttle cruising and deceleration. Low pulse width balancing is crucial for a smooth idle on large injectors.

Transitional Range (2-4 milliseconds)
The transitional range covers the pulse widths that typically make up the non-linear range of injectors. Many high-flow injectors spend a majority of their running time in this range.

Linear Range (4-1+ milliseconds)
The linear range pulse widths are used during medium and high load conditions. Proper balancing in this range allows for advanced timing and increased boost pressure to yield high and safer peak horsepower.
