Smitty,

If you would like to add another parameter to your test, get an LCR meter to measure the characteristics of the coil.
You may be able to correlate the results.

Did you ask how they flow test them? A certain duty cycle?

They said they had a custom machine built thats labratory grade, temp controlled, tested at idle , mid than high rpm. I do my test at 750rpm 2ms, 2400 rpm 6 ms, 3000 rpm at 8 ms, 4500 at 9 ms then 5500 at 8 ms, this pretty much mirrors the pw time on my tune from 502 i have on my dyno

This is the video I was trying to find.

Pretty slick where you can call up with a serial number of an injector and they can send you a matched replacement.

I'm curious how these would flow on your machine.

I'd sure as heck would not want one of my engines blowing up because of a crappy injector! Thanks for your help Smitty.

I flowed and tested the (6)80 pound Sieman's Deka injectors today that came from racetronix as a match flowed set that are going in our 600-horsepower 3800 turbo project and they flowed plus or minus 1% even at high RPMs, impressed!!

I looked up the ID injectors. They are Bosch EV14s like I used to work on. I think improvements in controlling the tolerances of the parts that make up the magnetic circuit would have helped those. Like I said, the densos with turned main bodies were the cats meow. The EV14 had a deep drawn body with no other machining processes. The coil and coil housing tolerances could get out of wack and still be to print because some moron with an Indian name wasn't smart enough to do a stack up with a radius tolerance and an angle tolerance, I figured it out years after the release but no one cared. I think that could have affected the mag circuit strength and repeatability.

Flowed a set of stock injectors Saturday from a 220,000 mile 6.2 chevy LS that has sat for a year (customers motor thats going in a jeep), they flowed within 5% of each other with just 15 minutes of cleaning in ultrasound, flowed a set of injectors today from a 90,000 mile 2000 Camaro LS 5.7 that sat all winter that we are installing cam and intake on, they also flowed within 5% with 1 cleaning cycle in ultrasound, it seems these stock oem injectors flow MUCH better than any Mercruiser injector I have tested to date!
