The lbs of the injectors are irrelevant. The quality of the injector is really what you want.

Thats why its absolutely useless to run anything less than siemens deka 80s. They have better atomization, linearity and flow control than any other injector in its price range. Its also an OEM ford injector and ULEV certified. Siemens has strict 2% QA requirements so flow testing isnt needed.

Just be mindful the siemens injectors are the most copied and knocked off injector ever made and are impossible to tell the difference without cutting it open since the knock offs use authentic siemens housing from the china manufacturing issue that happened a few years back.

SIEMENS and SIEMENS are not the same.
lowercase is siemens and slemens. A lower case l with all else capitals is identical.

Did you check with DJM or Ricks Rangers? They may be able to make them as well. Ricks has a nice set of upper control arm mounting brackets that raises the mounting point to correct for camber as well.

decipha,
I understand your reasoning, but have a few issues with those injectors.

First is that are going be capable of almost 100 lb/hr at my fuel system's rated 65 psi. I know you said don't worry about flow rate, but that's about 3 times what my engine needs. I have no interest in poweradders and the bottom end isn't built for it if I was, so room for growth isn't a concern.

Second is price. I was saying fresh injectors, not new injectors. I was planning on a set of flow matched Bosch 0280156048 or 0280155849 that had been rebuilt and flow matched for around $200. Those would flow about 30 lb/hr and support 350-400 hp from my understand, which I believe is going to exceed what my modifications are capable of. To buy those Siemens from a reputible source (to ensure no counterfits) will run almost $600.

Boostedeverything,

DJM does not make anything for lowering the torsion bar Rangers, I'm not holding my breath waiting for them to start either. Rick does not make control arms for these, maybe he will in the future, but not at this time. I have been in contact with him about some of this. Rick does have the raised mounts, but not something I'm going to do.

1) I don't want to cut and weld suspension mounting points on the frame. At least not for the front, flipping a hangar or welding on sperches in the rear is a different story.

2) I've had the truck for 20 years and don't intend to part with it. Right now I'm building towards an idea that I've had for years, time will tell if it works out the way I want. If it doesn't, it has been lifted (slightly) in the past and it may happen again in the future. As such, I don't want to modify the frame mounts.

Even if I were willing to cut and weld on the frame, from my understanding the raised mounts will not clear my headers. I also wouldn't trust my own welding, so I've have to find someone I trusted to do that and have to tear the engine bay back apart for clearance to weld them in fully. I'm working towards what I want, but I'll scrap the plan and return to stock height before I use the raised mounts.

Whys it make a difference if it can flow 3x more?

The siemens are just over $300 from poweraddersolutions using discount code DECIPHA

The siemens are far superior than both the boschs you list or any other injector you can buy anywhere near that price range.

Oh, I don't know.

Minimum pulse width? I don't know numbers, but it stands to reason that if both injectors have the same MPW then the 3x larger injector is going to spray 3x the fuel at that MPW. Given my relatively low power build, that might be too much fuel for idle and low RPM conditions. Given how & where I'll be driving this, that is definitely a consideration. Regularly passing through speed camera enforced 25mph school zones. The federal installation I work on has a highest posted speedlimit of 35 mph, much of it is restricted to 15 or 20, and the security has a lot of time on their hands. Idle, off idle, and low rpm drivability is definitely a concern.

Amount of fuel it has the potential of dumping into the engine if it gets stuck open? Either one would be bad if that happens, but the smaller injector might be a little more forgiving with the amount of time it takes to do damage from fuel washing the walls and bearings. One larger injector stuck open would dump the equivalent of three smaller injectors.

Resolution of factory ECU? An ~97 lb (@65 PSI) injectors is going to increase flow exponentially faster than a ~30 lb (@60 psi) injector, about 3.2 times as faster. Essentially I'll only be able to use about 1/3 of the 97lb injector's flow. Will the factory ECU have enough resolution and fast enough response to fine tune and adjust the fuel tables with that in consideration?

Ignoring the atomization and spray pattern, say that they were both Siemens Deka injectors, is there anything to be gained by having three times the needed potential in a fuel injector?

Considering the amount of potential counterfits out there, I was looking at prices from what appeared to authorized/official Siemens retailers. They list them up to $80 each. Poweraddersolutions never came up in the search or in my reading on your site. If you vouch for them as selling legit products I am willing to give them a consideration. That said, I tried it and your discount code is not applicable for the EV6 version of the injector that I need, so still over $400 for a set.

PW is irrelevant. Injector size has abolutely no bearing on injector control. Your explanation is entirely flawed. Thats just like thinking youd be better off having $30 dollars in your bank account instead of $80 since your only spending $5 on a burger. The amount of headroom the injector has extra in your bank account is entirely irrelevant. The stock cobra jet engine still has to idle at 5hp perfectly and pass emissions. The 80s will have far better fuel control at low pulsewidths than the boschs.

The injectors are listed on the homepage aee the pre tune info page. PAS is the only legit vendor afaik. Even ford racing and summit all are supplied same as them. Siemens hasnt made any injectors recently so there is a bit of a shortage.

If the discount code doesnt work give them a shout and they can get you sorted.
