The BIG DZL Project: 500hp...1000tq...20mpg
Picked up this 2015 Ford F350 Platinum 6.7 Power Stroke from Texas a few weeks ago. BIG DZL was built in Kentucky on 1/15, arrived to the Texas dealer in February and was in Florida by March.
The truck will have to work hard; towing a 12,000lb boat, hauling palettes of pavers, stone and other materials, working on construction sites around the country, traveling long highway miles and performing off-road from Florida swamps to the Colorado Rockies. BIG DZL serves as the foundation for a 500/1000/20 project build. We'll be working to get up to 500hp, 1000 ft-lb of torque and over 20mpg overall. The objective is to create the ideal balance of beauty, performance, efficiency and utility...to upgrade the truck and still achieve these milestone numbers...all without sacrificing any of the Super Duty's significant capabilities, including reliability. As configured today, we should be at ~450hp/900tq (will be running real Titan dyno numbers soon)...we averaged 15 mpg calculated at 75-80 mph traveling from Texas to Florida and we've gotten 17 mpg over 90 minutes on cruise at 70 mph speed limit. Truck has 1940 miles as of 4/8/15. Welcome any and all suggestions, recommendations and advice to help reach our objectives from the many experts on this forum. As well as any other comments anyone might have for that matter. Starting stock configuration: 2015 Ford F350 SRW 4x4 Crew Cab Platinum 172" Longbed, 6.7 Power Stroke V8 Diesel Ruby Red Metallic over Black Leather Preferred Equipment Package 618A with 20-inch wheels 3.55 Electronic Locking Axle 11,500 GVWR Engine Block Heater Roof Clearance Lights Upfitter Switches Spray-in Bedliner The mavens at Texas Truxx kicked off the modifications and added the following as of 3/2/15: Suspension and Steering:
Once back in Florida, we added these bits (3/9/15):

None of the stuff you have done til now, tho pretty nice looking, contributes toward the goal you mentioned.
at 440/880 (stock hp/torque), you should be able to get the 500/1000 easily with any of the tuners. Might have to do a delete.. that 20mpg (average) will be a challenge, unless you are going to drive 55. also, that lift pushes you in the opposite direction.. more lift, more wind effect, less mileage. you are driving a big flat front sail. same for the larger tires. I got 16.7 hand calculated on my 2012 f250, highway over 13,000 miles.. some short spikes to 17.. never higher.. with the 3.31 rear. Once saw the dash say 20, but only for a few miles, and was running in slow traffic. if you get it, I want it. my 2012 dually usually gets 14.. I don't need any more power. |
Definitely possible. My ol tuned hot rod has been making these kinds of numbers for a few years now with no issues
20ish mpg would be easier to achieve with stock height/tires though, lol. I used to be around there driving on the highway before I added bigger tires, etc |
Also, many of us tow FW trailers well over the 12,000 lb weight with the stock setup and don't consider this 'hard' work on the truck. My FW weighs 12,000 dry and you would hardly know it is there except for startup from stop. Mileage drops to 10, but it also is a big sail.

Thanks much for the perspective...forgive if I didn't explain the objective clearly enough. Keep in mind...the goal is not just mpg, that is just one (though important and very challenging) aspect of the overall objective...which to reiterate is "...to create the ideal balance of beauty, performance, efficiency and utility...to upgrade the truck and still achieve these milestone numbers...all without sacrificing any of the Super Duty's significant capabilities, including reliability." All the candy improves aesthetics and some of it various aspects of performance, the CAI and exhaust improve power, performance and mpg, the flush bed cover improves mpg, etc. The point of this build is to prove that you can have it all...what we are doing is attempting to find the right combination to get us there...something very few have been able to do, which is what creates a worthwhile challenge. Of course, the easy way out would be to just leave everything stock and drive 55...and that's all well and good, but it's done all the time. We want to prove that you can upgrade your truck, including lift/tires and still achieve these milestone numbers (500/1000/20). It would have been just as easy to go the other way too, say 10" Fabtech on 40's and No Limit the whole truck...but that sacrifices balance, efficiency, utility...etc. By finding just the right balance of mods, we might (and that's a big might, especially on the mpg-front) just be able to have a great looking, lifted truck that performs and gets great mpg. Hope this helps clarify... |
Welcome to the forum... As others have stated, you'll have no problem towing 12k stock. I just picked up my new RV that was 16k dry and it towed like an arrow. I'm all stock. I also agree that your mileage goal is the toughest to achieve. The rest, many have done. I'd be doing it too if I didn't live in a state that checks for emission equipment every year at inspection. Enjoy your project. Looks like you're having fun so far!

Based on long participation here, watching others. I don't think for this breed of engine, CAI or exhaust size make one difference, til you get WAY up in power.. 7-800hp.. but as noted that is way outside the balance point.
the headlights, if they actually improved vision, might be something I am interested in, but most of the rest is just fluff. It doesn't improve or detract from the trucks effectiveness or utility. it does empty someones pocket pretty well tho. I have an led light bar on my dually, cause the headlight mods haven't helped practical vision. I'm interested, tho skeptical, in one primary goal, mileage. I would have set out to get the 3 goals, and saved the rest til it was achieved. but to each their own.. I throw money into customizing old trucks, and the FW. |

Towing capacity for this particular 3:55 truck as configured is 14,000lb, so consistent work at 12,000 will prove hard work enough... Here is Ford's SD towing chart...which I'm sure has been posted countless times, but is still useful as reference... 2015 Ford Super Duty | View Towing Specifications | Ford.com |

Absolutely and thanks much for the welcome...the possibilities are truly endless with these rigs!

This might be helpful regarding intakes and exhaust...The legend that is bigrpowr sent these dyno numbers recently to illustrate the difference a good CAI can make...the numbers speak for themselves, especially when looking at the lower register... "I dynoed my truck this past saturday. I am still waiting on the dyno graphs which I will post up later but I wanted to fill everyone in with the results. For the dyno testing we felt that to get the most accurate results we would dyno mikes intake, the afe intake, and then the stock intake. Here are the peak hp and tq of each intake: Peak Hp Stock-442 Afe-444 No Limit-451 Peak Tq Stock-1027 Afe-1044 No Limit-1058 As you can see the no limit has a pretty good gain over the afe. But what was really impressive was when we started breaking the tq numbers at a given rpm. At 1600 rpm (Tq) Stock-386 Afe-448 No Limit-512 At 1700 rpm (Tq) Stock-515 Afe-571 No Limit-663 At 1800 rpm (Tq) Stock-693 Afe-748 No Limit-825 At 1900 rpm (Tq) Stock-872 Afe-931 No Limit-942" |

I think I've read something about them there limits... ;) Haven't seemed to be able to take them to heart...
this is mostly a tire & conventional hitch location limit.. the dually, with the same engine and trans can go to 23500, 19000 if you use the conventional hitch. so the guts are good.. engine/trans/chassis. and the surrounding stuff is the issue.. tires, wheels, springs, and hitch location. I've seen some cool wheels and tires, but a lot of times they reduce the weight capacity. One of our other members, PaintedHorse, with a newly arrived 15, had to select specific wheels to keep capacity up on his 350 SRW. |
Welcome to FTE Big! I hope I can call you Big?
Anyway, it sounds like quite an interesting project. Like some of the others, I'm a bit skeptical on the fuel economy, but won't say never... When you select your place to do the dyno testing, see if they will give you the graphs exported to Excel spreadsheet (they are literally all capable of doing this now) and they should include the IAT, Coolant Temp and BFSC figures through the range of the pulls. The headlights are of key importance to me as well.. Mileage not so much. My camper weighs roughly 18k and the truck never breaks a sweat dragging it.. The Ford 6.7 is a mature and very capable engine... |
Truck looks great so far, few minor things id change but i think you've sold me on ruby red for the color of my 6.7... curious to see how you get 20mpg though

The Ford 6.7 is a mature and very capable engine... Certainly will do regarding the dyno runs...Titan has all the toys and data. Going to have to get creative to increase mpg further...could use all the advice we can get (even reached out the to the hyper-milers...no, we're not doing a monster-dam or fastback tonneau!). Might have to dive into gearing and aero...tunes might help as well. At the end of the day, the best solution on this one might just be to trade in on the lighter/leaner aluminum 2017!! :-X04 acf6--loving the throw-back candy-apple red. Ford calls it RR, but it's really just ol-school candy in the sun. Everyone has their preferences...but please feel free to send along any ideas you might have. We've already made several tweaks based on feedback we've gotten along the way... |
The mpg is going to be hard unless you do some wind tunnel treatments. I contend that without some aero work under the truck and some kind of fastback treatment behind the cab/above front of bed you'll be fighting much too much low pressure drag to get consistent numbers in all kinds of wind conditions.
Good luck, I truly hope you find a wind tunnel somewhere to work some things out. I've been thinking very hard about some way to negate the drag behind the back windows. I have the back flip too and at 72 mph the back flip cover is actually pulled up from the bed 12-26" behind the rear windows. I'm not a good engineer so I don't know how to work the numbers but there has to be a good 20hp drag right there. |
