I built my own flow bench so I could check my stuff and help out others I race with. Now it's time to check the flow rates I observed to the published flow rates. Anyone familar with this type of stuff?
What's the easiest way to do it. Convert the lbs/hr rating to cc/min? I am using graduated cylinders which are marked in cc's. I am using mineral spirits as the liquid.
I'm not so concerned about an injector flowing exactly what it should, more concerned that they all flow the same. I have a set of 83 lb/hr injectors that were flowed on a real bench, they all showed the same. Well, two of them weren't and almost hurt my motor! Six of them are identical, one was a little lower, another a lot lower! I caught this with the spark plugs and pulled them out and put my old injectors back in there. No damage was done.
This is what led me to build my own bench. I am using a real fuel rail I built so I don't have to pull the screens to check the injectors. They are being flowed exactly as if they were on the motor.
These 83 lb/hr injectors fill the tubes VERY FAST!
