    I don't drive a big rig at the moment, but I do have an '01 Dodge Cummins that I haul cattle with. I've installed a Bully Dog product and have sign a 2 to 3 MPG improvement over stock. I've heard that they have developed something similar for the big rig market similar to what Pittsburgh Power has.

    Well said Brick!

    Here's mine

    2003 W900L, C-15 CAT propably over 1000hp at the engine, 18 speed, 3.55s, 290"wb with a 48' spread axle reefer. Always 80,000lbs if not more, with about 4 feet in between sleeper and trailer, yes very un-aerodynamic.

    Last trip from west coast and back i got 5.7mpg, with a very hot pyro reading do to turbo not pushing enough air for new ecm. With new turbo i bet ill be around 6mpg. This is pulling a very non aerodynamic reefer 4500 mile round trip

    Are you absolutely certain about your claims I've highlighted in bold??????




    Now I'm not a rocket scientist, I'm not even a college grad but my hick town high school edumacation tells me that your numbers on a volvo are WORSE than mine with a large car with a CAT.



    I'm feeding MORE horses, hauling more weight and running a lot harder. CATs can get good MPGs. It depends a lot on the driver and some luck like I'm currently having.


    and


    This rig is pulling more weight than I usually do, but I don't think I would see much different MPGs if I was running this sort of route.

    People who bag on CATs have to realize that most of your "bad" millage with a CAT is achieved with large cars, sine 80% of your long nose trucks are CAT powered and you're vacum cleaners are detroit, vulva, whatever. You stick a 550hp CAT in a vacum cleaner century and it will get 7mpg......... If spec'd right ofcourse :biggrin_25523:

    Oh and when i was pulling trains in MI grossing 160K+lbs i would get 5mpg out of my 550 stock CAT. Guys with detroits, who were always complaining about lack of power with the weight, would get 3.5-4mpg.

    A century radiator is going to have a hard time keeping the power house that is a CAT cool enough. A C12 or C13 maybe, but certainly not a C15 pounding the ground.

    Nah ive seen some, they got those high-flo radiators, they can handle them. Just like the older 387s half of the grill opening was the rad half was the intercooler.
