3.7 Forced induction

If we can get all the parts together he plans to use MPT for tuning. I was trying to save him some money by giving him the old 72 lbs injectors and my boost-a-pump.

I can't find a straight answer on if they will fit. I found a good deal on some and I passed it up because I didn't know. Give them a try and let us know if they fit.

I will definitely find out. Thanks!

Well, we know all newer mustang years (2011 and up) all utilize an EV14 injector style. While the sizes can vary (lb/hr), the fit to the fuel rail is consistent across the board from the 4 cylinders to the 5.0, but the EV14 also comes in different body styles like @Patrick eluded too above.

Body styles of the EV14 (USCAR) used in Mustangs:

2011-2017 V6 (compact body)
2011-2017 GT (standard body)
2007-2014 GT500 (Standard)

The compact body style is what the V6 uses, but nothing says the standard won't fit...and actually the 52lb Ford Performance Fuel Injectors that are standard on the 2013-2014 GT500 have been used and fit the 3.7L just fine. You get 56lb//hr @ 4 bar fuel pressure when using the 52lb. So I think you will be just as good using the upgraded 72lb for the GT500. Only thing I would be worried about is if the tuner will use them, because many require a flow rate report or only trust certain brands i.e. how MPT tuning won't tune a procharger unless you use DeatschWerks Fuel Injectors.

Are you 100% sure standard body injectors will fit under the intake manifold? I have read some places they will and others they won't, I could never get a definitive answer. It certainly looks very tight. I haven't taken my intake off yet, but the fuel rail looks like it's almost touching it with the shorties on there. There is a layer of insulation, do you have to loose that to fit the standard?

MPT Tuning won't tune a procharger unless you use DeatschWerks Fuel Injectors.

The 17U-00-0072-8 he has are DeatschWerks injectors. The injector calibration data is right on their website, it's a simple cut & paste for the tuner. MPT has been less than excited to work on V6's lately from what I've heard and they might give you a hard time anyway.

What's funny is that DeatschWerks claims to have injector calibration data for all their injectors on the website and as far as I can tell they do... except for the 16U-00-0065-6 lol. I emailed them about it and they sent me pre-release data and asked me for input on it.

I know what he has is the DeatschWerks. And yeah, your correct from just reading around no one seems to have the definitive answer on if they fit or not. I mean we are saying the same thing just in different ways...but, I know factually the Ford Performance 52lb injectors (the standard 13-14 GT500 set) have been used in a 3.7L application. Do I know if the 72lbs DeatschWerks GT500 variant will fit, no, but they aren't anything bigger dimensionally speaking then the 52lb. So by that comparison I am saying I don't see the issue. I haven't personally done this so I can't 100% say anything, but since the OP isn't talking about spending money on parts and just trying this out I am advising based on what I am know that this should work out. Maybe it won't, but I think they will be fine even if it requires some minor modification.

As far as the injector calibration data or flow rate report goes...well, not every fuel injector you get will produce an official report (lots of re-bored and cheap knock off chinese crap). Sure, the major manufactures do, but having tested and verified data is important to a tuner. My tuner won't tune remotely or otherwise unless I buy my injectors from him period. He only will go with what he has bench marked and trusts. BUT, your so, so right about MPT...they are finicky about how they tune for us.

Do you know how much if any modifications were needed? American Muscle advertises a standard hight injector for our cars so I figured they must fit, but man if you look at the fuel rail it's practically touching the bottom of the intake manifold with the shorties in there, and I could never find anyone who had actually done it.

This 100%. Really even most manufacturers don't. The way ford does the calibration data is very different than other manufacturers. It's not something that a tuner can just figure out like other brands. You have to get the data either by reading a tune from a vehicle that uses them stock or from the manufacturer. That's why they will only tune with injectors they know they can get data for. That's why I'm sort of annoyed that DeatschWerks does not list any data for the 16U-00-0065-6 on their website. If procharger uses them for their kits then they must have the data in their tune. DeatschWerks sells the same injector for GM in a set of 8 and has the GM data on the website, but Ford uses a completely different method. I'm not sure what I'm going to do yet, I was going to try the "pre-release" data they sent me, but if the standard size injector body will fit, that opens the door to injectors with known data available.

No modifications were needed, but as a disclaimer it was on the S197 3.7L and not our S550 (though this shouldn't matter).

Yea that's where I'm at too, I can't find anyone who has done it in the s550 and I think the upper intake manifolds are different.

 

[Patrick]

Made some progress this week at least. Haven't had much time lately.

I already had an intake spacer so I drilled and tapped it for vacuum references to the recirc(BOV) valves.

I put the new upper grille and lower grille delete on.

And the drivers side turbo is now attached to the engine. Have about 1/4" clearance with the steering shaft.

 

[Patrick]

Got some more work done. Injectors, plugs, thermostat, drivers side charge pipe. I'm going to refill the coolant, pull the fuel pump fuse and crank it a couple times to check for leaks tonight or tomorrow.

 

[Patrick]

Little tip for disconnecting the fuel line. After you pull the red clip out, you still need to use a fuel line tool to disconnect the line. I watched a couple different videos on removing the manifolds and none of them explained this. One guy said he broke his clip, this is probably why. I already had the tool and it was fairly obvious to me, but figured I'd mention it.

Nice, nice, nice, nice....progress looking good. Seems for went the stock eco charge piping. What T-Stat you go with? A guy over on the Facebook forums blew his number three piston with the kit cause his tuner was running 15 psi on non-modified stock turbos using pump gas...I was like what were you thinking.

15psi on pump gas? WTF maybe with meth injection idk. No. Very different than the stock ecoboost pipes. I went with the Mishimoto 160 degree thermostat.
