DIY flow tested my Nismo injectors. And now I smell like gas. Bad.

[neech]

So I took these out to sell them, and a guy asked me if they needed to be cleaned or not.. Since my #2 cylinder just went out, and I have not yet found the reason, I couldn't honestly sell them to him and tell him not to clean them. I didn't feel like spending $100 some dollars to get them tested and cleaned, so I decided to flow test them myself.

I turned on my fuel pump via AEM EMS, and connected the battery to my MR2 while it was running to get constant voltage. I used a hacked injector harness a la Gavster and connected it to 12v one at a time, for exactly 60 seconds, spraying into a bottle of which I marked where 740CC was with a sharpie. They all came out within 5% of each other, which I think is pretty decent. Here are some pics of the process.

These are Nismo 740 CC injectors BTW, that are up for sale


Injectors


3 1/8th cup ~ 740 CC


Filled the slimmest bottle I could find, and made a reference mark.


The Setup::
Peekaboo


Engine bay with injectors in place.


Set the fuel pump output in AEM to stay on


The system was connected to my running MR2 so that I could get constant voltage across the fuel pump.



Fuel pressure was a tad below 50 PSI for the whole duration of the tests.


Testing:


Results:






After, I referenced 755CC and 770CC on the bottle to get an idea about how much more was being sprayed. I wish I would have done it before, but from the pics you can tell that it isnt much higher than the 770cc mark.



Just thought I would share!!

Oh, and if anyone tries this based on my thread, make SURE you don't make ANY electrical connections anywhere near the injectors
