Those people you know are right about the Duramax you know. How does +155 hp and +385 lb-ft of torque sound with a simple chip. I say your either driving a Duramax or you're behind one.

 

my father owns a landscaping company and just bought a 1 ton dually crewcab ford and gmc truck. We placed a fifth wheel trailer carring a large ag-tractor and tested both on about a 100 mile strech of interstate with a 7% climb in the middle. The duramax out pulled the powerstoke by about 5 mph average and got 1 mile per gallon better. I dont think the duramax is stronger but has a better tranny due to the allison. The duramax has a engine braking feature that made the truck really shine above the powerstroke. Comming back down the grade the duramax would hold speed where we had to ride the brakes pretty heavy on the ford. we had a gross vehicle weight of about 30,000 pounds. Yes, i know the legal weight is 26000 but we really wanted to worrk them hard. I think this is a fair comparrison due to the fact he owned both so it wasn't bias. i know after this i will be buying a duramax for myself!

 

I wonder why Chevy went with the Izusu Duramax when Izusu makes better inline 6's which is a superior design?

I hear the "Duracrax" won't hold up to high boost pressures though? I like Chevys but they are so small.

The chip upgrade is impressive, but real power still lies in the Cummins. They dominate diesel truck pulls. Not with the Dodge AUTO though! Manuals only.

 

around here htere are so many cars it is VERY limiteed classes
i was in the 327 no NOS no bullshyt class as we call it
i did major motor work n still havent broken it in yet but b4 i beat all the mustangs that where there (a guy wit a 68 camaro beat me)
i just bored .40 over n many ohter mods that ull just have to find out for urself [img]i/expressions/face-icon-small-wink.gif[/img]
oh n its a corvette engine by the way

the best car was a 67 mustang wit a chevy motor........

 

I had an 82 GT 5.0 (The best year!)
But I loved going to the track & seeing the Buick GN's hammer all the pretty boys in their 87-93 5.0's. That was always a good laugh.

 

You right, Dodge Cummins have real power and is only medium duty diesel engine available to public. Alumax and powerjoke are light duty truck.
And you can put lot of different chip upgrades in them too.
rnuts

 

Actually the IH motor is available in the Ford 450 & 550's right? That's like a lumberyard truck. Medium duty I think.
Think if Ford used the DT466 IH !!!!

 

CHEVY D/MAX W/ALLISON TRANNY!
