Description

Genuine Bosch 1550cc fuel injector

A great solution for those looking for an unmodified injector that flows over 1000cc per minute.

We purchase these injectors directly from Bosch Motorsport Australia

  • 1584cc/min at 3 bar (43.5psi), up to 2,236cc/min at 6 bar
  • flow matched within 1% across a set of injectors
  • high impedance (high resistance) so no need to add ballast resistors on some ECUs - remember to remove the ballast resistor if you have been running low resistance injectors
  • excellent injector dynamics make this injector incredibly easy to tune
  • modern design with linear flow rates
  • full stainless steel internals

The medium injector cap takes the injector from a stubby/short 1/2 length injector to a 3/4 length injector. The long injector cap takes the injector from a stubby injector to a traditional full-length injector.

This injector is also referred to as the Bosch 1650, 1462 and 1600cc

DO NOT get this injector confused with the Bosch 0280 158 827 full-length injector. They are not the same. The full-length 827 is a CNG injector and the fuel flow varies dramatically with fuel temperature, making it unsuitable for use with petrol and ethanol.

Dynamically flow tested in New Zealand by us, Motorsport Electronics (MSEL), so that your set of injectors is matched within 1% across the entire set.

How many cylinders does your engine have?

Step 2 of 4 — Fuel & Induction
What fuel are you running?
What type of induction does your engine use?
Step 3 of 4 — Pressure & Duty Cycle
What fuel pressure are you running?
bar

4.0 bar = 58 PSI

What is your maximum injector duty cycle?
%

ℹ We recommend a maximum below 80% to leave headroom for tuning. Different applications might want to see a lower duty cycle (ie 65%). This is best discussed with your engine builder and/or tuner.

What is your target lambda?
λ

ℹ Lower lambda = richer mixture = more fuel required. Default is set based on your fuel & induction selection. Adjust if you know your target.
