Little comparison for ya!

 

Basic answer is that the Cummins is just a tougher engine than the Powerstroke is, but also it's not smaller than the Powerstroke, yeah it has 6 cylinders, but the displacement of the two engines is nearly the same give or take a few cubic inches. In stock form they're basically all tuned to be within 10hp/10ftlbs of each other to stay competitive, but once you get tuning big, that's when the overdesigned internals of the Cummins really shine through in terms of potential power numbers.

Nice post.

 

ok, thanks that solves my question, and dont get me wrong because i have a ford but i love both cummins and powerstroke, i just wanted to know the difference

 

Looking back at the gassers a 300CI inline 6 cyl has more torque than a 302CI V8, the V8 claimed more HP. 99.9% of all class 8 trucks use an inline 6 cyl, more torque, longer lasting.

 

Thank god for the inline 6 cyl cummins!

 

So much misinformation, so little time.

 

I know that an inline motor will usually make better torque than a V configuration because you are not running multiple plains of torque, meaning the pistons are all on the same plain while in motion.

The fact still stands that the Cummins is a Med. duty where the Stroke is a lighter duty.

 

not true, scania a europeon truck company makes 600hp out of there 15 liter v8 as a factory option mack made a v8 cummins makes v8's too, its all in the application the way i see it.

 

....


One thing...

Injection system.

 

How about hte fact than an I-6 has 7 Main Bearings compared to a V-8's 5 main bearings? That makes a big difference...

Cummins does make a V-8... The 903. Its nothing to brag about, and anyone who has one wishes they could swap it for an 855 I-6. Trust me, I've run, and worked on both, and the 855 is a better engine all around. The 903 can really make some HP with a bit of tuning though... Shame a tractor doesn't need HP.
