Couple Detroit Series 50 Questions

Brian Diehl · January 05, 2016, 12:40:50 PM

Get the CPL for the engine. The CPL is the critical parts list. This is a number. It should be on the engine data plate. Call Cummins technical support with the CPL and they can tell you exactly how much the engine can be turned up without replacing interior parts. The CPL for my engine is good for 450 hp. I have it currently set at 400hp (what it came programmed at).

Thanks Brian, I will call him tomorrow and see if he can get me that number, Do you have any pictures of your install? Is it a 9?

Cummins ISL 8.9 liter is about the same length as the Series 50, but a lot shorter. ISL can be turned up to 450hp and 1250lb/ft torque and is available with Jake brake. Nice thing is the ISL is still in production, while the Series 50 is not. Good Luck, TomC

Plus the ISL is a heck of a lot smoother running than the S50 being that the ISL is a 6 cylinder while the S50 is a 4 and they tend to be rougher running by default.

Well if everything goes right Ill have a series 50 sitting in my driveway this weekend. Then the transplant begins. If any body that has done this into a MCI9 and have any pictures to share or tips I would really appreciate it. Jason

Now this I'm going to follow.. was thinking thinking about a D60 conversion in a bus with a 8v72 motor.

We have a D50 in another bus so if i can help at all (not sure how, but hey..) just holla.. only tibbit of advise is the fueling can be tricky on the D50, spent hours troubleshooting a problem and the problem was a stick return valve from the head..

Good luck!

I'm a little surprised that Jack Campbell ("Blue Goose") hasn't commented. There are a number of D50 conversions in the Southeast and Jack was involved with several of those. He is very familiar with many of the details (not sure which models of buses, tho).

Me also, I sent him a PM and a email to the one he has in his profile a few weeks ago

Jack has been sick, going to Dr again today.

I read that there were 5 MC-9's with S50's at Arcadia this year. The year I was down south I saw three or four of them. From what I saw putting the engine in there was pretty easy, getting the electronics to work was almost the hardest part. Throttle pedal sensors hooked up to electronic speed controls and all of that. I recall that one just used one of the stock MC-9 radiators for cooling. They all seemed to use a laptop computer as the dash gauges. I was mucho impressed and immediately started measuring to see if I could fit one in my MC-5.

Sorry to hear that, Jack. Hope you're 100% better real soon.

TomC · January 08, 2016, 03:30:54 AM

Maybe if you butt the S50 right up to the rear door, it would fit. Then how would you power the radiator blower? Plus the S50 is much taller than the 8V-71-and that barely clears the bus floor on a 5. Best conversion for a 5 is a 6V-92TA. Good Luck, TomC

Does anyone know how the N14 fits in.. I'm not convinced about a D50 (parts prices, balancing issues etc etc), and it looks my dream of the D60 is fast disappearing.
