- Bold denotes the rated pressure.
- Length is o-ring center to center.
Spacers
2 1/2" (64mm) injectors require 12mm (7/16") rail spacers when using the S4 intake manifold and fuel rail. If you are using an RS4 fuel rail you will need a 1" spacer! 1 1/2" (37mm) injectors require 15mm (9/16") injector spacers with the S4 fuel rail.
| mm | inches | Bosch (not c-to-c) | S4 injector spacer | S4 rail spacer | RS4 rail spacer |
|---|---|---|---|---|---|
| 37mm | 1 1/2" | 33.60mm | 15mm (9/16") | N/A | none |
| 52mm | 2 1/16" | 48.65mm | none | none | 15mm (9/16") |
| 64mm | 2 1/2" | 60.65mm | N/A | 12mm (7/16") | 27mm (1") |
Note that Bosch's EV14 length specs are not o-ring center to center
Adaptors
| Connector | Shape | Bosch | A.K.A. |
|---|---|---|---|
| Jetronic | Rectangle | Design II/EV1 | Minitimer |
| USCAR | Oval | Design III/EV6/EV14 |
Injectors are male, harness is female, so to use a USCAR/EV6/EV14 injector on a Minitimer/Jetronic/EV1 car, you need a USCAR (female) to Jetronic (male) adapter.[1][2]
Conversions
lb/hr to cc/min
- 1 lb/hr gasoline = 10.5 cc/min (@720 kg/m3) - (1 (pound / hr)) / (720 (kg / (m^3)) )
- 1 cc/min gasoline = 0.72 cc/min
Flow dependency on pressure
- 3 bar = 43.5 psi
- 4 bar = 58.0 psi
- 5 bar = 72.5 psi
- RC Engineering's online calculator
Common test fluids
- Density of typical test fluid = 760 - 770 kg/m3
- 1 lb/hr = 9.81 - 9.95 cc/min
- Density of n-heptane = 685 kg/m3
- 1 lb/hr = 11.0 cc/min
- 1 cc/min = 0.685 g/min
Instrument cluster
If you change fuel injectors, your instrument cluster will estimate your fuel consumption incorrectly. Use VAG-COM to adjust it by going to Instrument cluster (17) -> Adaptation (10) -> Channel (03).[3]
Unfortunately, you can only set it to a maximum of 115%. Default is 100%.
If you have access to ME7.x tuning tools, you can completely fix cluster consumption by adjusting the KVB 1x1.
![{\displaystyle TKVAG={\frac {\sum _{t=0}^{TMAIN}(rk_{w}+rkte_{w})\times KRKTE[ms]\times KVB[cm^{3}/min]\times 1000}{Kd[mm^{3}/s]\times 0.0512[ms]\times 60000}}}](https://wikimedia.org/api/rest_v1/media/math/render/svg/82bb01df5da6bf4020cbfd8f7cfb205baeb0c9dc)
