Going the VNT route..

[AH64ID 603]

Well I bought a 6.7 Turbo today, it should be here in a week or so. I got the turbo, manifold, and stock coolant lines. Now to save for the controller.. I will want to do studs first, so it will probably be some time before the VNT goes on, but it was a good deal.Fleece makes the controller and its pretty sweet. Its fully automatic, and include an exhaust brake function. You can custom tune the program to run the VNT like you want, and to limit max boost. Then there is a cab mounted dial for fine tuning the nozzle if you want, so on hwy trips you can open the vanes up to drop boost/DP and increase mileage, or towing heavy you can tighten the vanes a little for faster spool up. The compressor/turbine are the same size at my HE351CW, 60/60 but the housing is 3-26, so when its dialed in I should be able to have a little lower DP while towing which should lead to slightly lower EGT, but the bottom end while towing should be nice. I can't wait!

Oh now this sounds neat! Get pics of the whole swap, showing differences between the 2 turbos! Sounds like it will be worth it.

[AH64ID 603]

I plan to do a good write-up. I think in the sub 400 rwhp range this will be a good setup. I only plan about 350rwhp at most. I also don't think the 5.9 will have the DP issues the 6.7 has due to the lower displacement.

[dorkweed 298]

You should be 350-400rwhp right now with just the Smarty Jr. and your present set up. Stock rwhp is usually around 280-290.

[AH64ID 603]

The way I normally run it is 330/675, and that was without any of the bolt-ons*. I have been trying SW2 for a couple of tanks, and will tow with it for the first time tomorrow. I have yet to tow my TT with anything by SW1 or stock (only once to storage, wow I like Smarty EGTs!)..

I figure that with the airflow improvements and turbo mod it will probably be more like 330/700 since the boost will come on sooner and the ECM will fuel harder sooner. If I decide I like SW2 it should be about 360/725 or so..

Once I get the turbo on I'll re-dyno to see where I am at. But honestly the SW1 has been great, never short on power for towing around here.

SW3 gave me 428/807.

*I don't expect any hp gains from the bolt-ons, but I expect a little tq since the turbo lights sooner.

Okay, so those were corrected numbers..

UNCORR

Stock 285/520

SW1 TM4 290/610

SW1 TM2 290/589** Normal setting

SW1 TM3 293/544

SW3 TM4 380/704

SW3 TM2 385/708

SW3 TM3 386/712

(Subscribing) Sound interesting...

[ISX 58]

Stock 285/520 SW1 TM4 290/610 SW1 TM2 290/589** Normal setting SW1 TM3 293/544 SW3 TM4 380/704 SW3 TM2 385/708 SW3 TM3 386/712

Alright I am not up on all this chip stuff so what does SW and TM mean?

[AH64ID 603]

SW is software. SW1 is economy +40hp timing only; SW2 is towing, +70hp timing/duration; SW3 is performance, +100hp timing/duration. TM is timing in the adjustable "revo" options. Order of least to most TM1, TM3, TM2, TM4 (TM1 is stock, TM2 is default).

AH64ID could you get so good pics of that turbo and maybe do a write up of the turbo install I'm sure there is more people that would love to read up on this...

Read Mike! I have never seen one up close so I think it will be neat as ever. Tell the UPS man to hurry up.

[AH64ID 603]

It will be quite a while before its bolted up, but I will get some good pics when it gets here. I haven't played with one yet either..And for you guys with older trucks, Fleece has controllers for the 98.5-07 trucks right now, and will have the 12V model soon (TPS and MAP will need to be installed on the truck)

Lalala...

So I missed the first post... I really curious too... I bet he's dying to see the Brown Truck show up...

[AH64ID 603]

It arrived on Thursday, but was damaged in shipping :mad:The compressor housing cam loose and damaged the compressor fins, and the fins damaged the housing. It was insured, so going that route with UPS right now. The guy I bought it from has a line on another one, so well see what happens.The turbine housing on this thing is HUGE, considering it holds the VNT I am not surprised. I do like the design of the 6.7 manifold thou, all 6 cylinders dump into one collector, instead of being separated like a 5.9, and especially a 3rd gen 5.9 that is 4/2 on the collectors. That alone should help flow/tone.

[Mopar1973Man 3,593]

That's sad... Well at least its insured and a new one is coming soon...

[AH64ID 603]

I need to get some pics off to UPS to finish the claim..But UPS brought me a new comp housing and comp wheel today :hyper: I haven't seen it yet to see if they damaged this one yet, but knowing Richard at GDP UPS could do anything they wanted at it would arrive unscathed!More to follow....

[Mopar1973Man 3,593]

You know I might have to run down to Kuna and play with your toyz with you...

[AH64ID 603]

That would be fun! I figure the install will be in April.. gives me some time to fund and install the studs, and to fund the controller, manifold/turbo blankets, and anything else I may need. So the new wheel and housing are here, and in perfect shape!!

[ISX 58]

What is the word on this thing? You got it mounted in the showroom and scared to put it on? I know it is nice lol

[AH64ID 603]

Its in the garage displayed proudly on my bookshelf, awaiting the rest of the funding!

[ISX 58]

Guess I shoulda reread the last thread. Didn't know it took soo much stuff. I'll send you a lottery ticket so you can get that thing on there before Armageddon hits lol.

[AH64ID 603]

Well as some of you know I sold the VNT turbo. I wasn't happy with some of the programming restrictions of the controller. The biggest issue, the deal-breaker, was that the exhaust brake couldn't be left turned on while cruise was being used. The EB doesn't use the EB lead from the ECM, but TPS and in cruise the TPS is at 0, so the EB would be on while trying to maintain speed... So.. it looks like I am going to $$ up and run a Garrett Ball-Bearing 3788 in their Stage 3 powermax kit!A little more cash, but a LOT more turbo!

i have one of these apart on the workbench right now. they have a very unique way to control the vanes. i'd get a pic, but i'm sure it won't come out, the cool part is inside the bearing housing where it's all dark.

figured i'd rebuild the turbo before i used it.

what downpipe were you planning on using? you have a third gen, so either the 6.7 or hx40 would work for you. i'm leaning toward a 6.7 full 4" after i crawled under a truck at the dealer yesterday. i had been wanting a 6.7 full 5", but that would probably mean modifing my 5" exhuast a little bit, but the 4" looks like it will slide right in place.

[AH64ID 603]

Any 3rd gen downpipe will work, 5.9 or 6.7, so my stock one would bolt up to the OE 6.7 elbow. I am not sure a HX40 would clamp on without mod.
