No brainer that the inline engine produces more torque. Hp is derived by the RPM the engines can spin to...again no brainer that the V engines spin faster thus produce more HP.
Lets take a look at the spes.
Ram 6.7 385 hp @ 2800 rpm
900 ft/lbs @ 1700 rpm
Ford 6.7 440 hp @ 2800 rpm
925 ft/lbs @ 1800 rpm
Duramax 445 hp @2800 rpm
910 ft/lbs @1600 rpm.
Again... Horse Power is a calculation.
Torque in ft# X RPM /5252, thats it...this is the only way to calculate Horsepower
I also dont buy those numbers above. The V8 diesels red line almost 1k RPM above the I6. Do the math yourself.
Buy the numbers or not but they are the numbers published by the respective truck manufacturers.
Take The time to look them up at the respective truck websites.
Despite popular belief the chassis dynamometer measures horsepower directly and then the computer calculates the torque curve.
Look up how a chassis dynamometer works.
Who cares whether horsepower is measured with a scale, a ruler and a watch or a tach and torque transducer. Either way it is a meaningful value. Torque on the other hand has no time associated with it and is therefore almost useless on its own.
