    Wanting to supercharge the 5.9...

    Really considering putting a blower on my 5.9. I know it’s going to be a lot of work and money, and there are a few build threads on here. What I am looking to do is put together one thread that can be informative instead of having to search and sift through all the other threads. Also, a lot of the threads are not updated so some information I see posted those parts are no longer existing, or other alternatives are now available.


    Since this is not a DD for me, I am not afraid of being a test dummy to an extent. Not looking to blow my stuff up LOL.


    So anyway, this is what my 5.9 has and anything in orange is what I think I will need to support a supercharger.

    Your on the right path,,,,, not sure if you can get an adjustable fuel regulator for the stock basket, Just let the SCT take care of setting your injectors with the 42's.

    I run twin pumps with full return system, but this is not necessary.

    Look for a used Dodge Dakota System and make a battery relocate bracket to move to other side,,, All in my build threads

    Thank you for the post! So even when running a larger fuel pump and injectors the SCT can compensate for fuel pressure? I am used to my turbocharged systems that when you combine these two (without AFPR) you can overrun the stock FPR and end up with worse gas mileage and running pig rich all the time.

    Having a boost referenced regulator is nice but not required.
    Chrysler is speed density, there is no MAF.
    with SCT I can dial back the Pulsewidth for the big injectors. Not a big deal at all.

    I don't think it was mentioned, but you're probably going to want to stick with the Vortech blowers - I believe that's optimum for us.

    The problem is the Magnum motor Vortech kit has been discontinued.

    The real key to the kit is really the engine bracket and maybe some spacers. From there it could be pieced together - but most likely you'll just find a whole kit for sale.

    I'd start checking the Dodge forums for that.

    Procharger makes a kit for the 5.9 Durango/Dakota, still in production. It's about $6k, however. And we wouldn't be able to use most of the piping or the intercooler setup either. But it's an option to get a blower / bracket combo for the engine. I wonder if they'll sell just the bracket?

    Yea - I would hope with $6k I could piece something together myself lol. Even if that means getting that plate/bracket custom fabbed. Appreciate the info thus far, really helps sorting me out so I know what I definitely need.

    That one Logan posted looks like a good deal or at least close to what you should be looking for.

    You know this part, but besides the bracket - heart of the kit is the head unit and that one only has 2k miles on a rebuild.

    Bracket and everything else are non-wear parts so you should be good to go, so either pay a little more and get one with a newer or rebuilt HU, or buy an older kit and have the HU rebuilt for peace of mind - maybe even upgrade to a better HU.

    ....and note that it comes with a set of iron eq heads! If that's not what you'd want maybe he'd sell it cheaper without them?


    Hopefully someone else will chime in on this but from what I've been seeing over the years Vortech is pretty much what you want to stick with.

    You could maybe bounce that off Ryan (flyinryan) for confirmation.

    I may have located a Vortech V1. We will see how that turns out...for now I am just trying to build up what would be required, so whenever I am ready I can slap it on. Not sure if I will rebuild the heads haven't thought that far yet lol.

    I am more concerned with the transmission and bushings at this point. After I get the Energy Suspension CA bushings installed I am going to shoot for the IronMan4x4 MM and Trans Mount as the next "big upgrade". Then just make sure to go around and replace any gaskets that are looking worn.

    for a blower, all you NEED is....

    2 BAR MAP
    42# injectors
    255 LPH pump
    SCT (from ryan, obviously)
    blower (with brackets, air hat, and tubing)
    bypass valve (NOT blowoff valve - flange welded to charge tube)
    colder plugs (not NECESSARY, but....yeah....it is)

    when i put mine on, i went ahead and put a set of 1008 head gaskets with studs in - as im runnign 12#
    any exhaust upgrades will help a LOT

    Cool! So I have some stuff already with the step colder plugs, Thorley headers, and 3" exhaust. Finding the rest should hopefully be easy.

    So, you recommend going 2-steps colder for the spark plugs? Wanted to confirm the P/N for this as a few come up...

    NGK P/N: 4644
    NGK P/N: 2667 (Iridium IX Spark Plug)
    NGK P/N: 5791 (V-Power)

    Will do as you suggest since I will be reaching out to you for the tune!

    I have a question I'm also on my way to supercharging my jeep I have the blower bracket piping, most of the stuff, but I didn't get oil lines. Which ones would work?

    Are you referring to oil feed, oil return, or both? If you have a Vortech, the manual is online which includes a parts list. If you let me know which one you need I can look on my parts list to get you the measurements.

    Right - what actual supercharger do you have though? Not sure the compressor will be universal and use the same thread pitch for the fittings you would need for the feed and oil return. I have the bracket as well, but I am sure a blueprint would be helpful for others!

    Oil Drain Assembly:
    1/2" x 18" Oil Drain Hose
    3/8" NPT x 1/2" Straight Hose Barb
    #8 Stainless Steel Hose Clamps (2)
    3/8" NPT x 45* Street Elbow

    Oil Feed Assembly:
    1/4" x 33" Oil Feed Hose
    1/8" NPT -4 x 45* Male Elbows (2)
    #4 Swivel x 1/4" Hose Barb Fittings (2)
    .525 Crimp Ferrules (2)
    1/8" NPT x #4 90* Fitting
    1/8" NPT Female Tee
    1/8" NPT x 3" Nipple

    The oil feed T's off the stock oil pressure sending unit from my install booklet. Looking at the list I am wondering if it would be better to just do the adapter from NPT to AN for the fittings and lines.

    P.S. I Google'd "Vortech <part from above list>" and it seems like most of these are still available from Vortech.
