[QUOTE="TheFleshRocket, post: 16683538, member: 48535"] Ahh, okay.. yeah the B556V part number does come back as 47# injectors. Thanks for pointing that out. I figured maybe Deatchwerks was just modifying stock Ford injectors so I went poking around on their website and found the flow characteristics for their 39# and 60# injectors under "Tuning Data - General Characterization Summaries". 39# - [URL="https://deatschwerks.com/collections/injectors/products/18u-01-0039-8"]Matched set of 8 injectors 39lb/hr[/URL] 60# - [URL="https://deatschwerks.com/collections/injectors/products/18u-00-0060-6"]Matched set of 6 injectors 60 lb/hr[/URL] Sure enough, at 2.0ms pulse width, the 39# is rated at 0.0080 cc per shot, whereas the 60# is rated at 0.0123 cc per shot, approximately 50% more. So if these really were 60# injectors, when they've flowed 100ml on my test bench, the 39# units should have flowed approximately 66ml. That's definitely not even close to what's happening. [/QUOTE]
