Siemans SBD injectors (INJ-690)
laptoprob - 28/4/15 at 02:25 PM

Bought 2 months ago and run on dyno to find they are too big (cc) for my installation.

SBD tell me they are the best they sell with a better spray pattern than all the others they stock!

Perfect for all those going big power this year.

Cost me £350 + p+p

First £225 can have them. (free p+p)

Hi, these are 690cc injectors each so at 3 bar it would be roughly 400 bhp if you are supercharging.

Sorry i don't understand the 'duratec' question.

If you are running Jenvey throttle bodies from SBD then yes these will fit fine?

Why are you not using them? It is easy to map them to an NA engine.

All new ecus would be able to reduce the 660cc's down comfortably to get the car to run well on the lower end of the map but my OMEX 600 wasn't quite good enough so became very unsettled. Swapped for 400cc and it mapped perfectly.....
