    Cummins 8.3 (6CTA)

    I heard back from Cummins Customer Support today. Thought I would share this with you and for any searches in the future. Thank you for that ESN. I was able to pull up the information. It actually looks like the best RPMs for you would be about 1500-1700 RPMs. Here is what that will give you...

    Cummins 8.3 (6CTA)

    That's interesting, everything I found regarding the two newer engines (ISC, ISL, 24 valve head) said they didn't spin as fast as the 6CTA engines. The explanation was because of the fuel system and 24 valve head.

    Cummins 8.3 (6CTA)

    I saw that in my searches but nothing is listed for the 210hp engine. It sure does look promising for figuring out the cruising RPM. According to the email I got back from Cummins the best RPMs for the engine is around 200 RPMs more than the Peak Torque specs. He asked for a serial number and I...

    Cummins 8.3 (6CTA)

    You are theorizing the same questions that have been running through my mind. I can see where in some cases these engines would need to run the higher RPM’s. Perhaps, industrial generators, Marine applications, Farm equipment to name a few or if my truck was under a constant load, but what I am...

    Cummins 8.3 (6CTA)

    The tag on the timing gear cover shows a CPL 2101 and I also found a place where it showed advertised horsepower rating 210 @ 2200 RPM. I had a chance to drive it again this morning. Seems like the power starts pulling about 11 to 1200 RPM and than hits a wall at 21 to 2200 RPM. Don't know if...

    Cummins 8.3 (6CTA)

    I dont have any verifiable information or charts as if yet. Its a new truck to me and I have only driven it one time so far. I was trying to get factory info on it for a baseline. Its amazing that the information is so hard to find on the net. I have an email into Cummins but have not got a...

    Cummins 8.3 (6CTA)

    Looking for a little help from anybody that has the older Cummins 8.3 (6 CTA) mechanical fueled engine. I have a 1996 Freightliner FL70 with the Cummins 8.3, Eaton 6306A, 4.33 rear gears and 11R-22.4 tires. Its current setup is a 26’ flatbed and GVW is 34k. It buzzes along at 2100 rpm at 60...
