1000cc decapped injectors
I did have to put new connectors on, these are EV6. I flowed them static and they were all right at 1000cc, had 1 at 1020 and 3 at 990 then 4 dead on 1000. However my flow rig is pretty barbaric and the 4 that were 1000cc i timed myself, the other 4 i had a helper so i bet thats the discrepancy. I plugged in ID data and they have been flawless. I put my LS orings on these injectors mainly because they were new. I believe the top is the same but the bottom looks different.
Great, i need to quit dicking with it tho. I was playing with my iac table and got my desired and dynamic airflow to match which has bothered me knowing it wasnt right. Redid my idle airflow. Then i started getting a surge on return to idle.
So i went back to my normal iac table and and raf and its good now. Im not sure why it started doing that, but im thinking it was from subtracting from the entire iac table whrn i think i should have just moved the values over to the right a few spots.
Such is life i guess. Tuning a stock PCM can be a PITA sometimes lol
I forgot i am having 2 small issues. I started turning more RPMs up to 6200 and it goes lean over 6000. However my voltage also drops at the same time, like you just turn the alt off. I think im turning the alt too much and the voltage drop is killing my FP. It drops from 13.8 to 12 instantly. Im hoping its just belt slip but i doubt it. It is the smaller truck alt so i may need the big one?
either the short case or the long case truck alt ought to have the ad244 rectfier/diode bridge/brush assy. you could be floating the brushes but usually thats a gradual drop.
i think it's more likely you are overspinning the alternator. there are larger diameter alt pulleys
i have read the max rpm for stock alternators is 18000rpm
so (crank pulley dia / alt pulley dia) x crank rpm = alt rpm

Wonder what the Raptor injectors flow... Seem to be more of them available cheap. Maybe the same thing?
AL3E-F7A is the PN. Some say these are a 6 hole 47lb injector. Others say 33lb

I found this. Says they are 32 lb @ 39psi and the pic shows 6 holes. Also the raptor isnt the only truck with the 6.2, alot of f250 and f350 have it and a few normal f150s have it. It was a special order for some of the f150s. The new raptors have the ecoboost engine btw.
On a side note i tuned up a 6.2 the other day in a f250 and the secondary plug wires will work on ls coils (it has 16 spark plugs). They aareabout 15 inches long,

I have recently aquired some 05 explorer 4.0 injectors which are the same as 4.0 mustangs. They look just like the ones i currently have but are shorter, like truck injector length. When i get some time im gonna decap them and see what they flow.
I have done 2 sets and they both flowed about 1000cc per min. Janky flow bench but they were within 3% iirc.
I just recently decapped Ford 4.0 injectors out of mustangs and explorers and they flowed 700cc per min. I was hoping they would be about the same 1000cc because they are shorter but no dice.
the ones in my truck have been great tho. There is a plastic ring that hold the oring on that I removed on the first few I did but started leaving it on since I think it needs it. On 13 psi I am at 55% dc I believe.
I have at least 1 set here ready if anyone wants to get them flowed professionally. I will pay the shipping to get them to you as long as you promise to get them flowed and post the results here. Just lmk

I'm still running my decapped injectors. I picked up a set of flex fuel injectors recently. I will decap them and throw them on my flow bench eventually. I think the flex fuel injectors are roughly 10 pounds more??
Iirc the flex truck injectors end up really close to 1000cc decapped. We ended up putting my truck decaps in my buddys cammed 5.3 silverado. Changed the ifr table and tuned the VE and they have been flawless.
I have a guy interested in my deal with the Ford decaps. So hopefully he will get some professional flow data on these suckers and we will see if they are as good as I think they are. Yes I am cheap and don't want to pay for it lol

I worked a deal with LsxFord to get the decapped injectors flowed. I sent them along with a set that I thought were the same but were not. The ones I found from an 04 F150 3v 5.4l that I decapped flowed substantially less than LsxFord’s. I sent them off to Eric Derr who didn’t waste anytime checking them out. I’ll let the data speak for itself.
That seems to be a A- grade, right? I am super stoked about those results, and also my janky af flow rig.
Please get the part # off of the ones I sent you and post it up. I will get the part # off of the ones I am currently running and we have the number I posted previously. I would like to thank you again for getting them flowed, it is nice knowing 100%.
EDIT Eric already put the part #s on the sheet in the top right corner.

Ok the set I am currently using are the same I sent you. Part # 0280158227 and the Ford part # is br3e- eb.
googling the bosch # shows they come in coyote vehicles. I'm pretty sure I havent swapped 2 coyote f150s, but quite a few 5.4 3 valve and 4.6 f150s. A little more research should get us some vehicles to look for in the yards.
Edit- Now that I'm thinking back I may have swapped 2 coyote f150s, I know I did 1. I have also found these listed for e150 vans from 01- 09. If anybody has a source from a Ford parts department they can type the part # in microcat without entering a vehicle and it will list what they came in. I may can get this done in the coming days.
