Static max flow in test environment:

29 PSI (2 bar) 420cc / min = 40 lb / h
43,5 PSI (3 bar) 510cc / min = 49 lb / h
58 PSI (4 bar) 588cc / min = 56 lb / h
78,5 PSI (5 bar) 657cc / min = 63 lb / h
88 PSI (6 bar) 732cc / min = 70 Ib / h
101,5PSI (7bar) 792cc / min = 75 lb / h

Note that the test environment versus practical use can have various results depending on peripherals and other technical factors. However, this is very good info on what to expect from the injectors and can be used as basic information when choosing other components for the fuel system such as fuel pump, fuel pressure regulator and fuel filter.

Bosch 550cc physical size

Bosch 550cc is a Bosch injector with a standard body (Standard 48.65mm)
Use this top adapter to get the Bosch long body (Long 60.65mm).

Bosch Injector length comparsion:

An illustration to compare the different sizes of injectors. The size is measured between the o-rings if you want to check the length of your existing injector.

Some injectors (not this one) have an extension (xT) from the lower o-ring measuring 24mm. This can be inserted to the intake manifold or rebuilt with the help of a lower adapter to get the standard 11mm protrusion.

Flow Matching:

These injectors are delivered directly with factory tolerances unless you choose to match those with much less tolerances than factory. Choosing to match the injectors with our top of line machines before delivery will get the matching much more correct, we always recommend if you do that. Or you can choose to drive them unmatched with greater tolerances, match the injectors themselves or compensate for the diffusers to divert slightly in flow when mapping the ECU system. How much they differ from the factory always vary.

When you choose to match the injectors, this is done with our top equipment! Documentation and certificates from us are included with the injectors when you choose this option.

Bosch original

We use Bosch original incectors because our customers demand reliability. Injectors can be tested by entering the digits on the box in an online test page for control.
