Injector flow rates?
I have a set of Bosch 0280155865 injectors design III from a mustang.
I need to figure out what they flow. I have found ratings from 24# all the way to 27# at 3bar.
Anyone know the truth? Thanks for your help

the 865 Bosch is a 24lb that will flow 25.6 in the chevy. But, that injector has a uscar plug not a minitimer plug so you will need wire adapters or pigtails for your harness. The other thing you have to do is put a ring in the bottom grove provided so it sits up in the rail far enough. if used as is it is too short and could leak. unless you have an aftermarket manifold.

Hey Jon....
I saw somewhere that Chevy fuel pressure was only 39psi "nominal". If true, wouldn't Ford injectors be closer to Chevy measurements?
Or, is it the case that nominal fuel pressure is always lower -- in any car? Or was the info wrong? (Obviously, we've heard 43psi more often).
(Really wish I could remember where I saw this, because I thought it was on a manufacturer or tech site.)

Yes, a few of my injector plugs were broken so i thought, why not.Do you sell the pigtails? if not im going to jump out in traffic and snip some of the next car..lol. So what you are saying is at 43.5 psi these flow 25.6# .. Ok, that what I needed. Thanks!

tony.. the pigtails are not needed on our l98 sets. the guy that needs them got later ford injectors that use the us car plug. you have what they call the minitimer plug on your harness, our Bosch sets drop right in.. hey I just got a ford crate engine in for a boat with brand new design 3 22's I can change them over to gm fitment and sell them to you if you are interested in a set that was never run. We are putting a blower on the engine and need to use 42's.

I'm definetly interested in them. I've been getting weary trying to decide what I need, it seems every one I read about has some kind of compromise associated with it or opens up more questions as to fit or flow rate or something that requires changing the ECM. I tired of reading about this, i just want to get her back on the road, drop the top and cruise.

Tony i won't sell them untill I hear from you. The whole set is $229. These are virtually impossible to find new. Ford price is 116 each. This is a no brainer. They have to be fitted for the chevy, no problem. They will replace the stock ones 100% or your money back. Let me know
