Turbo/Injector upgrade (Heavy Towing) Shoutout to Me78569

Your ultimate power goal dictates your path.  A single at 500 hp can still tow very nice.  

 

 

Exactly.

I don't like towing with wiretap personally.  I would leave it on lvl3 towing.

 

A killer tow setup with be 7 x .010's and that 57.   66lb/min is a good 400 hp worth of towing air.  that is a CONSIDERABLE upgrade over what you have now.   

 

All diesel guys love the idea of 500+ hp, but more often than not a 350 hp setup is more than enough to make you smile. We all suffer from the hp drive.

 

 

Not to downplay the 62/68/12 setup as that is a tried and true 500 hp DD / tow setup but I would personally be looking at the 57 if I was towing a lot and mulling over the idea of twins down the road.

 

 

either choice will work, the 62 will have more power up top the 57 will outspool the 62.   if the truck is more of a toy then 62 if it is more of a work horse then 57 :2cents:

 

 

x100.  

 

I just went through the same quest as you OP but I have no desire to run compounds.   I built a HX40 hybrid that is a billet wheel 60/64/12 for about $600 all in.  The turbo is amazing and does the job perfectly IMO in the towing application.

 

I just finished a 7 hour round trip towing a 14k 5th wheel and the turbo performed fantastic.

 

Agree with above... towing above level 3 (wire tap)  is kind of crappy because wire tap is not conrolled very well and tends to be abrupt/jerky.

 

The one mistake i made was buying 7x0085 injectors as an early mod when i bought this truck.  I should have gone 7x10s from the start and my truck would now be done being modded.

True,  some peak HP loss.  It depends on the primary and secondary goals of use for the truck.

 Primary is Daily Driver secondary is all towing. Truck doesnt get raced I dont think I've went past 3000 rpm since I've owned it the 5 inch exhaust and drone gets loud at 2800 lol. Here in Florida I'm 49 feet of elevation , where I tow to in New York 3-4 times a year is 1400 feet elevation if that helps any. Also dont plan on any weight over 26000 combined I dont want to gave to get a cdl for a hobby lol.

both turbos will do the job,  would you prefer faster spool at the cost of 100 hp worth of air or do you want that extra air with a little slower spooling turbo?

With the 62 I'd have to look at some valvetrain upgrades? Pushrod,valve springs. You promote the he351 turbo pretty good seems like the GXE 57 is a high dollar one of those which if Its a direct replacement seems to be the better option for me. Only thing that sticks out to me with the 62 is the 500hp and that would be the easier turbo to get rid of if I didnt like it. The faster spooling will help me on the hills up north since it will spool faster. I doubt I'll be in 6th gear going 75 up the hills but 60 in 5th seems more like a thing. The 57 GXE will most likely be the one I go with.

If you arent spinning high rpms and dont have an exhaust brake then no valvetrain stuff is needed.  The 62 can flow enough air to get into the area of springs being a good idea, but again not really %100 needed.

HE351 would have to be modifed to address the small turbine wheel and housing to = the flow of the 57GXE.  Call in when you are ready and state you are a MOPAR1973MAN forum member and we will get you a discount.  Happy to support the forum and its members!

If that's the case I'll probably go 62 dont really see the concern for exhaust brake unless I'm up north with the grades but plan on upgrading to 3rd gen brakes if that's a option for my truck. I baby the truck for rpms always shift between 25-2800 Thanks for all the help!

I wouldn't go any smaller than a 62 unless you are definitely going compounds.  The 62 will tow very well (especially with the manual trans) and make the kinda of power you're talking about.  Won't spool quite as fast as a 57 but won't run out of guts as fast either.  The spool difference is much closer together than the power difference is.  My 62 spools almost exactly like the hy35 I replaced...and way more air/power in comparison.

Has anyone had experience with Fenley precision inductions cam across there Facebook page for a hx 35 60/67/12 how would this compare to a 62 besides the price difference?

Modified HX35 and HE351 have their place, but its not =  an s300.  bearings are smaller, compressor housing is small.  It all depends on the application.  Always keep in mind the time to rebuild, and the loss of a core or good turbo to make the hybrid.  If one is in love with a project and it fits thier needs then go for it.  The SXE is such a good value.  Custom $2000 dollar turbos from a few years ago wish they could have been SXE turbos.

62 65 14 turned my truck into a towing machine.

I'll agree 350horse tows well and runs cool. I regularly tow 18k plus with cool temps. It definitely moves some air.

I think it spools fast. Fast enough to surprise many here. 

In 5 years itl be mandatory to have 62 almost like it seems the truck wont run without a quad now. Lol

Settled on the 62/68/12 150 hp injectors ordering through DAP and there throwing in a turbo blanket that should make up the 200 rpm spool diff between the gxe and ther sxe thanks guys

Should run great! Just got back from a camping trip at the coast. First trip with my hybrid. Pulled a 7% grade with the cruise control set at 57mph.   My trailer loaded weighs in at about 7,500 lbs.  truck ran great!  Couldn’t be happier.

When you get it installed please post back what your thoughts are.

Got everything installed huge power difference. Trucks alot of fun. Purchased a couple tunes  from mopar man and me, and also from a reputable guy off Facebook. Having a little egt issues with the towing tunes but useable. Going to try and turn the egts down some but so far enjoy it very much. It's a different type of animal together used to as the stock setup full throttle in the stock setup would get me in the 1350 area for egts,but the new setup about 1/2 throttle for 4-5 seconds will pop me up there. Plan on getting a gauge pillar and looking for recommendations on what 3 gauges to go with I already figured another pyro gauge.

Isspro is my go to for gauges.  The Quadzilla Adrenaline already has 20+ parameters to monitor and data log.  Would be cheaper to buy a second phone (or a used donor ) to keep it connected to the truck instead of using the one you receive calls on.

Are you running wire tapped.

 

I hit 1100 quick then that's about the roof.  I can run grades with my foot on the floor t about 2000 rpm feels and sound like it hold the trajectory with no asphalt needed.  :)

 

If your hot and the quads running my thiughtvwould be to shut it off . Tune from factory base line then bring in just quad timming then maybe alittle fuel if it stays cool
