Super cool seeing someone else who swapped in a 392 intake manifold! I'm really impressed that you did all the work yourself. I had initially started in on it solo, but wound up running out of time for a variety of dumb reasons and just had the performance shop do the heavy lifting for me. I'm glad that I did, given my total inexperience with wiring. Your project turned out great!

Thanks! I’m a true DIYer plus knowing what a shop would charge me would be crazy. Plus the less hands that touch her the better!

I was watching Richard Holdener doing dyno testing of gen 3 hemi's and he mentioned that 2017 and up 5.7's also got a dual runner intake, it came on Ram trucks. I checked and it's true! I've been trying to buy a 6.4 intake for almost a year now but it's either not available or too much $$$. Well, we have another source and it's cheap. I quickly checked eBay and got complete one that included TB injectors and the switching solenoid for the runners for $320 shipped. I've since found them for around $200. I got motivated by this thread and will be installing it as soon as I get some time. Just need to order new gaskets.
Will probably also do some light clean up on the ports, since it's all open now.
Only thing is I'll have to redo my cold air again, since on Ram TB is pointing up instead of forward. Not a big deal.
Also, I'll check out that controller posted earlier but I did see an option for short runner solenoid when looking through OBDAlfa options, so may looks at that as well. I have HPTuners ECU, so I should be able to adjust switching through there in theory.

All reports so far indicate the Ram intake manifold does not fit on the Durango or JGC due to the height..it won't fit under the cowl...so will be interesting if you can confirm fitment. There is also the 6.4L Ram intake too.

Ram 6.4 intake manifold snout turns the opposite direction of the Dodge/Jeep 6.4 intake manifolds (towards the passenger side). RAM 5.7 intake manifold snout turns up and will contact the hood. Maybe the 6.4 would fit with some intake tube routing?!?

The ram intake does point up but I'm sure I'll be able to make it work, will measure things up this weekend if I get a chance.

Do you have a tuner?

Don't have a tuner yet, still looking for someone who can tune HPTuners without leaving the car there for 2 weeks.
I may just have to do all myself (as I've done in the past with other projects) if I can't fine anyone to just do a dynotune as usual, 1-2 hours and done.

Ok, gotta show this to anyone doing this. It's only available from Modern Muscle Xtreme.

So, I measured up the RAM intake and there is indeed very little rom on top, not with stock hood anyway. I'm going to investigate rotating or even cutting off the elbow and gluing or hot-welding the throttle body flange to the intake directly.

Well I got rid of the MSD Window Switch setup in favor of using my unlocked PCM and HPTuners to control the SRV. Used all factory plugs and terminals. Fully integrated without any aftermarket parts! BTW MUCH cheaper than any aftermarket setup if you have a tuned PCM.

Details:

SRV connector clip facing up L to R front rear (1-2-3-4)

Pin 1-Red
*Fused ASD Relay Output BN/YE (PDC C3in 7) 16 gauge 20A inline fuse

Pin 2-Black
*Ground BK (PCM ground strap)
16 gauge

Pin 3-Green
*SRV Actuator Control Signal DB/GN (PCM C2in 53)
18 gauge

Pin 4-Blue
*SRV Sense Output DB/YE (PCM C2in 60)
18 gauge

Routed the wires following the yellow line. Through the black plastic cover at the front of the engine, under the engine cover between the fuel injectors and coil packs then behind the intake manifold to the SRV.

How is that working out? Looking forward to a follow up on this

Does the pcm need to be unlocked for this to work? If you're just splicing into existing wires, can't it work with the oem pcm?

It works [emoji846]

Yes, need an unlocked PCM to enable the SRV.

I used the correct female terminals for the PCM connector and the correct SRV connector/female terminals. Also used correct gauge wiring as the power/ground is 16ga and the two signal wires are 18ga. Only splice I did was to add the 12VDC wire to the Fused ASD Relay Output from the PDC. You could just use any switched power from the PDC with a tap-a-fuse but in the SRT wiring the SRV is getting it’s constant power from the ASD relay. Wanted to integrate it as close to factory as possible [emoji16]

Just a little update. I think I've found a more "simple way to do the RAM intake under Durango hood. I was going to cut the elbow and glue the flange like our stock. However last weekend I was able to do some more measuring and thinking about the issue and I've come up with an idea of making an elbow with a flange that will bolt up to the intake instead of the throttle body and will move throttle body to a better position. This leaves plenty of clearance to close the hood and also has the effect of increasing the plenum volume. I have the 4" elbow and pipe left over from when made the cold air for the larger throttle body, so just need to order some aluminum plates for the flanges. If I get the parts by this weekend, I should be able to tig something together next week.

Able email call me like know how did half covers so I know how do them my self cuz I’m just putting covers on

 

[Elijah2017Durango]

So you went with custom fuel rail and vacuum lines? You've outdone yourself once again. Great looking work. What's the part numbers for those?

I’m asking 2 that have done half cover to message me so I can install mine that are coming in

If you reread what you posted before you will see that it made no sense. Just follow that thread and you will see the places he had to cut. If you aren't making any other mods to your motor then chances are that you won't need to make any cuts to the covers but you won't know until you test fit them. It's when you add parts from SRT motors or add an oil catch can that you might have to make some cuts. Keep in mind that the thread you referenced was for a motor with a 392 intake manifold, not a stock manifold.
