Hard numbers for injector flow rates.

Turboegt · Apr 3, 2017

Anyone have hard numbers for injector flow rates?

I'm looking for:
yellow injectors flow xxxcc/hr @ XXpsi
Blue injectors flow xxxcc/hr @ XXpsi
Red injectors flow xxxcc/hr @XXpsi

If you have it in lbs/hr that would be fine too.

I picked up some 1200cc injectors at 60 psi and am wondering how much I'm gonna have to scale them to get them to run on my yellow injector sled.

I just had blue injectors from a 2011 assault tested , they put 45 lbs psi to them and determined 39 and 41 flow rate ,I think that's lbs per hour ?

Saw your other post. Who did you have service your injectors?

NW injection service in Surrey BC did the work , they say before and after testing showed the same flow rate but a better spray pattern and they replaced the basket filters in the injectors.
In the past have injectors you had tested had equal flow rates or is a slight difference typical?
Another thing I think about is my 12 pro has green rubber spacer seals between the injector tip and the cylinder and the injector the 11 assult has none, I put some in it and they fit and it all goes together well- anyone see a problem with this? If it matters its blue injectors.

I just got back another set of injectors from servicing, this time the machine they came out of was a 2012 800 163 pro and the injectors are black .
Flow for the black body injectors from the 12 pro #35

Blue 2011 assault 155 injectors # 39 and #41

I'm not so sure about testing and cleaning of old injectors, because if I bought new ones from the dealer they would cost 175.00 and would come with a new harness. To test, clean and retest cost a little more than 70$ and I still have old injectors and harness. Another thing to consider is on the assault the replacement injectors are updated and would require the ecu to be reflashed.

I would automatically replace any 2011 injectors and forget the cleaning.

I had one set a few years back that had differences. 2012. Can't remember now exactly how far off they were. But I replaced them. Sled had a goofy tip in throttle hesitation that cleared up after.

Possibly new injectors could have a poor spray pattern ,leek ,or different flow numbers . First time at the injector shop cost 40 cash second time different guy 73 bucks -I'm done with testing I,ll just buy new ones next time I have an itch to get them tested and cleaned

I do get that Dave , now I ponder that if I bought the new updated injectors my ecu would require a reflash. This motor has been done 3 or 4 times now
And twice its lost a mag side piston and cylinder. Possibly a newer ecu and injectors could offer a better fuel map ?
What's a good call for the 2011 assault?
