Talked to a guy today who has a kenworth with an N-14 with 1.4 mil no overhaul...BS? I'm partial to yellow myself it's a personal perference

I do like some of the innovations Volvo has built into the VED12/16, like the built-in exhaust brake that works in conjunction with the compression brake (making it super quiet) that also doubles as an engine warmer that restricts exhaust flow during idle to keep the combustion chamber temperatures up. This means the engine will keep sufficiently warm at a low idle, thereby saving fuel.

I have driven trucks with the ISX and the c15 cat and i prefer the c15 cat out of the three choices. Now i have a MBE 4000 and man that is the smoothest motor ive ever driven

I'd go with a 550 CAT. :P

I dont want anything cummin apart on ya. :lol: :lol: :P :P

I've never driven the new Volvo motor, so I can't tell you anything about it.

The vast majority of my miles have been in Freightliner Columbias with 14.0L 515hp Detroits. They don't seem to run up to the potential of their ratings, if you know what I mean. That 515 Detroit I have in my truck right now sure doesn't feel like 515. Of course it's also strangled to 1800rpm and 70mph... Currently a 6.0mph avg. I had a turbo replacement at 46,000 on my 2006 Columbia. My 2007 Columbia's 515 Detroit drinks a gallon of oil every couple of months.

The N-14 Cummins in the company Volvos we aucitoned off ran pretty well. The 430hp rating seemed a little low-balled. They would pull a load as well as the 515 Detroits seem to- but they also would rev out another grand. The last Volvo I drove told me 7.4mph average on the computer. We replaced a lot of fuel line T-fittings at the back of those N-14s, and you have to go in through the dash with the Volvo's set-back axle and subsequent engine placement.

I had a limited opportunity to drive a T600 with a 500 (?) C-15 Cat at Arrow. It's my favorite engine, but some drivers don't like them at all because the powerband is shifted so low on the scale. Progressive shifting soft-foot drivers LOVE them. If you try to rev them out they fall flat on their face, but they have all the torque in the world down low. The Arrow mileage champ averaged 7.4mpg pulling flatbed with a C-15 Cat.

-----------

All three are good engines, but if I were buying myself a new truck it'd be a large car with a 625 Cat. Unless that new truck was a Freightliner, then I'd have to go with a Mercedes MBE4000.

-p.

Very good observation! 8)
Except it won't "fall flat on their face" at high RPM, but it's gonna cost you! :wink:

MOTORS
 

I.. Think. Det 60. Series :)

I discovered a oil leak on my ISX the other day along the exhaust manifold. We'll see what the deal is after it goes in the shop (under warranty).
