    I'd be very interested in knowing how you got 600 plush and 2050 torque? I have a red top supposedly 525 in my winch truck. 18 &4 engine flat doesn't perform with my b model cat. I'd appreciate any useful suggestions?

    What's your CPL? I can tell you if Cummins re-rated it to 525 it yas the low box program and is not impressive.

    I got my dealer to put a 550 h.p. 1900 ft-lb program in my stock N14.

    It is a Cummins program for off road haul trucks. It pulls good but it does make some black smoke when you shift.

    When dealer called Cummins because upload kept failing, Cummins told me they wouldn't do it because my driveline wasn't rated for it. I told them "I own, I drive it, it's paid for and if it blows up I'll part it out."
    So then they gave it to me, LOL.

    Kudos to the original poster. For thinking outside the box. Water meth injection is cool despite the complainers. I find the 200 degree EGT drop on hills interesting. I’m seeing max 950 degrees on my setup with sensor post turbo.

    I started my driving career in N14s, off-road. Since have driven most of them. Cat, Detroit and Cummins of all vintage.

    To this day I’d take an m11, N14 or C15 over any. The N14... can idle for 3 weeks without shutting it off. It can pull heavy stuff through mud. It can run 20 years and not leak a drop.

    A genuine pollution emitter... no egr, filters or unneeded fluids. Just go.

    currently I’m owner operating a 98 M11 celect plus 370 hp. Day cab pulling containers. I’m gvw often.

    I might up it to 400hp maybe. I’m more concerned with making money day in day out, Than going fast. I’m finding slow is good. Getting the loads done is working.

    This 25 year old engine has 900,000 miles and doesn’t burn oil or leak a drop. She runs all day, every day.

    Take me back... To 1999. Celect plus

    I have a'98 M11 Celect+. What rear gear are you running? Mine is 4.33 with a 13 speed and LP 22.5's. I wouldn't want less. Had head gasket issues shortly after buying it in 2007 but after the sunken liner was fixed it's been reliable. Much better mileage than the 1995 N14 red top we had prior. Doesnt burn oil to speak of but it does leak it.... accessory drive cover.....oil pan....rear main. At least it won't rust. 1.2 million miles.

    It's in a T800 with a 62" studio. Paid $18,000 CDN in 2007 I bet I could get 2x that now.
