Glutenhauler Posted January 25, 2014 Share Posted January 25, 2014 VIN 1M1AK07Y87N023744 Can anyone tell me how much horsepower I have? It feels like the engine gives up going up a hill. There are a couple hills I go up several times a day that I end up in the low side of 6th before I stop losing speed. My boss gave me the ok to get a rerate. I found a thread on here with different options like the 460XT or the 427. I've got the Eaton 13spd but do not know the gear ratio of the rearends. I gross 86000 pulling a belt trailer. I would like to hear some opinions on what you guys think would ne the best option for the rerateThanks, Brent Quote Link to comment https://www.bigmacktrucks.com/topic/34385-looking-for-more-info/ Share on other sites More sharing options...

Macktech689 Posted January 25, 2014 Share Posted January 25, 2014 Check the decal on the valve cover, it will tell you what it is Quote Link to comment https://www.bigmacktrucks.com/topic/34385-looking-for-more-info/#findComment-228610 Share on other sites More sharing options...
Macktech689 Posted January 26, 2014 Share Posted January 26, 2014 If the VIN you gave is correct its a CXN613 with a ASET AC-460P engine. This engine should produce 485 HP if it is running correctly.

Glutenhauler Posted January 28, 2014 Author Share Posted January 28, 2014 Thanks macktech. The tag on the engine has the engine serial # and valve clearances but that's it. It's a Remack. I'll have to check with my boss to see when it was put in but I do know the local freightliner dealer rebuilt it 2 months ago. Hopefully I'll have time to get into Mack this week to get checked out Quote Link to comment https://www.bigmacktrucks.com/topic/34385-looking-for-more-info/#findComment-229177 Share on other sites More sharing options...
Mackpro Posted January 29, 2014 Share Posted January 29, 2014 As Macktech689 siad its a 460P, Back on 5/3/11 it was at a dealer and have the software and data files in the ECM's updated. Should pull pretty good when running correctly. Whats your turbo boost pressure under a load? We usually see around 33psi on one that runs as it should.

Glutenhauler Posted February 3, 2014 Author Share Posted February 3, 2014 No boost gauge. It's at mack right now. I'm guessing boost leak because I'm driving our 06 and there's a noticeable difference going up hills. Thanks again and I'll post results when I get it back Quote Link to comment https://www.bigmacktrucks.com/topic/34385-looking-for-more-info/#findComment-230252 Share on other sites More sharing options...
thomastractorsvc Posted February 11, 2014 Share Posted February 11, 2014 maybe it is because it was rebuilt at the freightliner shop?? 1 Quote Robert"I reject your reality and substitute my own."
