220cummins Posted September 6, 2015 Share Posted September 6, 2015 We are currently rerailing and legnthing our 82 Cruiseliner. I set it for a 176" factory wheelbase. It has a Formula 300 Cummins CPL 0471, Fuller RT-11609A, and 4.17 Mack 38k rears. Top speed with 24.5 tires should be 59.75 mph. I don't want to change the rears. I'm pulling the RT and doing a gear placement swap on the shafts to make a RTO with a overdrive of .73. Top speed should be over 75 which is more than fine for highway passing. I'd like to change the CPL to make the governed speed to 2100. I'd also like to get some more power, if possible, without changing injectors and the turbo. Eventually I'd like to squeeze as much out of the 855 even if that includes a out of frame rebuild, injector, turbo, timing change, and whatever else. So cummins guys what CPL do you recommend for now? Quote Link to comment https://www.bigmacktrucks.com/topic/41654-cruiseliner-cummins-question/ Share on other sites More sharing options...
Superdog Posted September 7, 2015 Share Posted September 7, 2015 All I did on my Cummins is change the button and spring in the pump,and adjust the aneroid screw. I'm pm you a phone # of a good old time Cummins guy ,he can tell you what button you will want to use.
