Injector specs (Page 1/1)

Is there a website that a person can go to to find out the spec (flow rate) of injectors?

I am specifically wanting to know the flow rate for some GM 17113750 injectors but seemed to have run into a wall trying to locate that information on them.

Talk to a local injection shop. Because they are cleaning and rebuilding injectors the have the specs you are looking for. Sleek

If those injectors are stock 2.8L they should be 15 lb/hr. If those injectors are 3.4L they should be 17 lbs/hr. For the 3800SC they should be 33 lb/hr

They are 3.4l, but I get conflicting results looking online from 17 - 22 lbs/hr, hence the question.

The 3.4 rated at 17# are at 43.5 psi. After three 3.4 swaps using OEM 3.4 Rochester injectors, I found all of them to run too rich. Bosch has several injectors for BMW's that fit our engine and flow 17# and run well on our stock ECM. If you are doing the 7730 swap with the 3.4, use Bosch 13641730060. Use 0280150415 for flow reference. Required injector flow is determined by the number of cylinders and the crank horsepower produced.
