40000 lbs gross work truck build

[Powerstroked162]

Then take your care somewhere else the only ones that drive it with that load are my dad and pap who have driven tractor and trailor for a living for 22 years and over 50 years I can asure you we dont need lessons on how to drive.
Yes I should have just called mpd to begin with. But I have the info i need

Call Craig up. He will take care of you. Be sure to let me know if you need an EGR delete too!!

I think you and hillbilly have made your point. Either way the op doesn't care what you have to say anymore so stfu

:blah:


Also feel like I should throw it out there that the F550 is NOT rated for 33k with the ZF6. Your GCWR is 26k.

No doubt in my mind it will live at that weight, these trucks are built like a brick ****house. But, just because you can do something... doesn't mean you should.

That is a sh*tload of weight to pull single axle. Good luck is all I can say, better be lookin at trans internals and axle assemblies too.

He will be just fine, anyone wanna guess what mpd's rig weighs hooked to the f350 cuz I'm going to guess it's over 30k

Our dually has crossed the scales over 30k numerous times. Has no issues pulling or stopping (electronic trailer brakes and jake brake tune), and I've had to jump on the brakes pretty quick before. I'm guessing the people "complaining" haven't pulled heavy with their trucks before.

The trailer has electric brakes that are bigger than the truck brakes. The trailer alone could stop the load so please if you don't have mechanical advice for the engine of the truck dont post anything.

:whs: I'd echo the advice of bulletproofing, tow tune, and maybe a mildly built trans w/ deeper pan. What about cooling the engine? When mine tows anything over about 5k on a hot day, it seems to overheat somewhat quickly.

Same here on the heat. I was towing my dads camper through Oklahoma on a day it was 107 in the shade. We were grossing 24k and my coolant temp was at 225, oil pushing 240 and EGT 1100+. That was with stock tuning. I like the idea about the bulletproof oil cooler cause that will take a little heat off the cooling system and a aftermarket CAC to drop your air temp going into the engine which will drop your EGT on the exhaust side. Now if your stick with the stock tune on the Cab and chassis truck you'll probly run cooler anyway cause the engines arn't tuned but to 250hp.

Are there any benefits to an aftermarket intercooler or are the results minimal?

Well on a truck with that few of miles you probly won't notice a lot of difference. Maybe 15% on a hot day and pulling heavy. Problem is when you start racking the miles on that light duty aluminum center section and plastic end caps. The aluminum starts cracking and caps start leaking. When you hook to loads in excess of 30k that turbo will be kicking 25 psi and 300 to 400 degrees into the CAC almost 100% of the time your moving down the road. Having a solid unit that flows and cools even 10% will make a huge difference in the long run.

I'm a big fan of the Banks set up. Replaces everything from the turbo outlet all the way to the intake. Only one problem... $1300!

Yea lol that was a hell of a trip 3600 plus miles with the 62/68/.83 t4 it towed very nice and didn't ever get hot

Through all that I found something that wasn't mentioned. Current EGT's while towing weren't given. Are they high? I ask this because nobody threw out the idea of bypassing the crankcase vent and getting that oil out of your intercooler... I have had alittle experiance with aftermarket intercoolers. The cores are pretty much the same and as stated the plastic end caps on the factory one are plastic. Obvisouly, a bigger aftermarket CAC would give you more cooling cappacity if needed. If you only see high EGT's on long grades maybe water/meth would work???
I saw you said that you didn't want aftermarket exhaust raising eyebrows. If you keep the cat and muffler, and don't have to have one of those can you see me now crome tips, it's not noticable. A flow through exhaust (if not provided by factory) does make a big towing difference. I know there is at least one company out there that makes a kit that uses a faux kitty ;-). I run a 4" aluminized turbo back and after 6 months I don't think many can tell the difference between 3-1/2" and 4" from 20 feet away. Again, I don't think the 1/2" pipe is as important as the flow-thru muffler.

As far as the vehicle limit goes... Those numbers are just guaranteed numbers from the manufacture. They would be liable for ANY failure under that weight and because they give that weight or number they are now not held accountable for any failures over that weight. Same goes for tires. They give the number to protect their company. DOT oke: wanted a national standard so they asked the manufacures to help create one. Thus, we have regulation... Nobody wants to put anyone else in harms way and as you can see the guys who spoke up are using brakes on their trailers to help stop them. If someone wants to test the pulling strength let them do so forwarned. If you own a tow truck, these guys keep you in business and if you're like me, you just honk as you wiss by them...
I'm sure 90% of truck owners have over loaded their trucks at least once. Remember a 1/2 ton is 10 bags of cement, 40 block, 100 brick, 6" of dirt, or a half scope of fertilizer.
