Tow rigs Pros and Cons

[mattzj98]

It's a simple build. 150 over injectors, full deletes, upgraded cooling, stage 3 heavy tow performance 68, better turbo, head studs, Fass fuel system custom H&S tune for engine+ trans, banks intercooler, a pretty intake horn, H&S cai, and few other goods I won't come up with while wrenching on the jeep currently. It's held up great, the torque converter is amazing, truck goes up Eisenhower in 6th gear, cruising at 75+

So Matt you have done full delete
As in no more EGR and no more after treatment? So no DPF?

Brandon-multi, the cummins with auto trans have more power!
The newer transmissions are getting really well built.
Converters are far stronger and lock up at much lower RPM.
The heat is an issue, trans coolers should never be run through the radiator.
Trans temp should stay lower than 195-210.
The hotter they get the sooner the blow up.
Thus why ours have larger external coolers.

I wonder if the fatories will ever figure that out.

If you can swing the $$ the new Chevy Colorado looks awesome and has a 4 cyl Duramax that can tow 7600 lbs and gets great mpg.

Not a cummins in the GM junk.
Its a VM matori engine. Comes from Italy and owned by Fiat.
They can't get the 3.0l v6 as dodge has contracted it.
Why it's a 2.8l they get the smaller less powerful 4 cylinder.
Yet it is still a great move for GM. As the Isuzu engine of the same displacment is a dog.
That and the contract is up.
If they get the 5.0l v8 cummins it could go into the mix sized truck, but I don't see that happening as the truck really can't deal with 350up and 550 lbft frame is not built for that engine...yet!

Full deletes, plates intake horns, turbo back, egr gone dpf gone the 19 cats that come from factory gone..

[dieseldoc]

Nice tossed a $15k Exhoust system.
Pea mandated restriction.

[mattzj98]

Who said I tossed it? Lol

[dieseldoc]

Lol....wouldn't put it back on that's for sure.
I so wish the EPA would leave well enough allows.

So example of the usless bull they are shoving down our engines

1980 Honda civic 1800c.f. that thing got 46mpg,
The new ones are still not cracking the upper 30's

My own experience
1991 dodge w250 cummins, this thing was 165up at the crank!
Built it with pump mods, fuel pin, rotated 180degrees
Injectors were 50 over
2nd gen impeller side (exhoust) housing this spoiled 42psi out of a 18psi factory turbo
So it was making 350up at the tires and getting 28 mpg.
Colorado made me turn it down to 170hp this then only getting 18mpg.
I had years of fuel economy and Dyno numbers.
This state is more concerned about choking the engine down then slowing it,to be efficient.
They didn't care one bit about the evidence to support the fact they made it less effective at doing its job.

What it comes down to is the Fed is forcing us to buy more fuel instead of getting all the power and efficiency out of our cars and trucks.
Hell the LSD they are making us use has less BTU in it to start with, then saddle the engine with a ton of restrictive exhaust parts that dodnt do ****.... Catalitic converter will do not a thing with diesel emmissins. Just along for the ride, thanks California
What it comes down to is an engine is nothing more than a air compressor
The harder to get air in and out the less efficient the engine is.

And now the EPA wants to make any aftermarket parts and running illegal
Wow talk about screw the industry.
My job will get harder and all of us will have to trailer our stuff to C.O.R.E as we won't be legal to run on public lands!

Dam it....3 government entities need to away....
EPA
OSHA
IRS

Don't forget the Bureau of All Things Fun and Exciting

Here's the funny part. With full factory exhaust I needed to use twice the throttle when pulling, while getting 8 mpg towing and 13 empty... passed emissions with a 4% opacity... did full deletes, added more powerr.. still passed opacity, and at 3%... so how the hell do they justify any of it

[dieseldoc]

ahh...my point exactly.

And here comes some new carp.
EPA is making any after market changes illegal.
With a $37,500 flat fine. WTF
So the Fed is trying to kill a multi million dollar industry.
More fleecing of America and more lean to the comunist/socialist agenda.

I had an 06 F250 6.0, loved the power and I was very lucky to only have one issue with that engine for the first 93k, then I sold it. Due to maintenance costs, I didn't think I would be in the market for another diesel again and would stick with a Ford V10 when it was time to get another 3/4 or 1 ton truck. But, here in CO, the elevation is a huge power drag. When I drive my gasser Expedition to Kansas, that thing is awesome and puts a smile on my face. When I come back to Denver, I notice the power loss and it's big. So, my next truck will be a diesel, just because of the elevation factor. Also, keep in mind that most owners manuals deduct towing capacity the higher up you are and most tow ratings are based at sea level.

And I'd recommend staying away from Ford diesels from 2003 up until this current generation. I believe it's the 6.0 and 6.4. Unless you like to work on them and spend lots of money.

'96 3/4 ton Dodge 12-valve Cummins 5-speed. One of my top 3 trucks ever owned. 21 mpg no matter what I did with it. And that was back before every other house on the block had one and shot diesel prices through the roof. Diesel was cheaper than gas back then, but holy smokes did I love that thing. 2nd best tow rig I had was a 91 F-250 SC long bed, 4x4, auto 460. 28ft fifth wheel and 18ft jet boat behind that, no problem. Luckily I got rid of that one while gas was still cheap. Other than higher maintenance and fuel costs, I'd go diesel again all day.

So the EGR crap we are forcing down the intake of the newer diesel engine is crap.
Spent gasses and suit are doing no good for the engines.

Water methonal is the way to go here.
A) it cools the cylinder temps, thus the get will never open
B) nice gains all around, better mpg, some hp, and it cleans the cylinders!

So what the he'll are we doing this DEF crap for.....oh ya the EPA has special interest groups who give big money for them to mandate there junk....so make money for them but not really do any good for the engine it's self.

Again I find myself calling B.S.
