Well I'm finally almost done with putting a series 50 in my bus. The bus hasn't moved under its own power for almost 10 months and hopefully by the end of the weekend it will move under it's own power again :) I bought a 94 Gillig transite bus for the transplant and I still needed alot of plumbing material but having the donor bus is the only way to go. Here is a few pictures

That's pretty cool. Nice piece of work.
It should have adequate enough power and get good fuel mileage, and last a long time.
Looking good Jason almost as good as the cabinets you build ;D
This has been a long time in coming for you. Now you'll finally be able to just go out and drive and enjoy your coach....no worries

Thanks for the complements guys, I sure hope I can go with no worries ;) Not sure on the power part yet, I'm going to run it as is this summer then send the ecm to bluegoose and see what he can turn it up to ;D It really is a nice fit in a 9 just like it was made for there.
Jason
Careful with your HP rating Chad H is looking for another series 50 for his Eagle his 50 series didn't last 10,000 miles set at 425hp but he was warned ;D
From a guy that has done 4 of them, that looks great. You will have something to be proud of when that goes in your bus. There are at least 8 series 50 running in this area that have had the horse power raised. None have given any problems. One has had 70,000 miles sense it was raised. We can make the ECM say anything you want, 600 HP would be no problem. What we are trying to do is get the most power without smoke. It doesn't make any difference what the power setting is the engine will only do so much.

Blue-Goose what do you mean you can make the ECM any horsepower you want ?

ECM's can be set about any hp but if you don't have the ingredients in the engine it a short life.I am building my 12.7 series 60 to 650 hp and it is not cheap I can tell you.The guy doing my ECM made mine where I can adjust the perimeters driving from my I Pad neat $#!% all this electronic stuff
I think I would be happy around 350hp - 375hp something safe but willget me up the hills.
Two things that need to be addressed with the Series 50. The balance shafts should be replaced every 300,000mi-these should be done now (if you don't know how long it has been since last replacement). And make sure you use the special soft engine mounts since it is just a 4 cylinder and rough at idle. Suggest you set at 350hp-more than enough power and it will last a long time. You should get about 10mpg. In my opinion, the Series 50 is the perfect RV/bus engine. It is so efficient, when Greyhound switched some of their MCI-9's from the 6V-92TA to Series 50's, they were able to remove one of the radiators and use the open space for the air to air intercooler. As I remember, they got about 2 mpg better than the 6V-92's. Good Luck, TomC
I bet 600 hp series 50 would last as long as a snowball in hell.Chad's 50 did good at 400 hp for a long time 425 hp just pushed it over the top.FWIW you see MCI's with a 8v92 set at 335hp from MCI
425hp would be nice but that sounds like a lot out of a 4 cylinder ;)

Just what I said, there is a box that you put the HP in and it doesn't care what you put there. Doesn't mean a thing.

Just what I said, there is a box that you put the HP in and it doesn't do anything to the program. Someone my think that means something. You have to add fuel to the engine to make power. You can add all the fuel that you want and make lots of smoke but no more power. Takes two things to make power fuel and air. Then one more, The ability on the engine to use the fuel and air.
The best you can do is to put in as much as you can with the least smoke. None of us know how much power we are running unless we put it on a dyno. When ever anyone tells you something else (don't believe them). Remember that box that the HP goes in.
Jack
Frignn HP is for drag racing, on a diesel engine the torque is what you are after no more no less. I am after 1950 ft lbs on a long power curve and a dyno comes in real handy tweaking a engine for air to fuel ratio and fuel burn
When you consider that the Series 50 is a 12.7 liter Series 60 with 2 cylinders lopped off, the highest truck rating on the 12.7 was 575hp. That converts to 383hp in the 4 cylinder. Good Luck, TomC
Also 1850 torque was the highest in the S-60 which converts to 1233 torque in the S50
What was the torque rating of a 8V71T? just for comparison sake ;D
My 6V92 with 9G90 injectors is rated at 1050 ft/lb of torque. My bus weighs 27000 lbs, and it goes pretty good. But when I tow the car, which puts me up at 32000 lbs + or -, it doesn't feel so great any more. So I am thinking the same power in a MC9 or similar weight bus isn't very much... When I used to drive a 102D3 with pre egr 12.7 L Series 60, that went up the hills with the cars, blowing the doors off any truck, loaded or empty.
The only advantage of a S50 over a 2 stroke like the 6V92 is that it only puts out half the heat. Then the mechanical versus electronic factor is a debatable subject...

I think you are right on with your HP and Torque. Sure would love to get it on a dyno and see for sure what it has. But who cares, it sure runs great
Jack
The series 50 is a good but not a great engine IMO,they hang around for a while @ 370 hp the 11.1 series 60 most of those are 350 to 370 hp with 2 more cylinders.Chads was a true 425 hp series I watched it tested on a dyno, talking to him last night he going with a 12.7 series 60 this was his 2nd series 50

What kind of coach was this engine in? Was the dyno on the engine or at the wheels? Where is this dyno, i haven't been able to find one that I can put the coach on.
Jack
His engine is in a Eagle 10 the dyno is in Albuquerque at a friends place it was a engine dyno.If you are ever in my part of the world Mohave Valley AZ
I have another friend that has a chassis dyno but you have to take full responsibility for damages he doesn't like to dyno buses
We have life in the MCI 9 again ;D The 50 series is up and running, we had a few wiring glitches but she finally took off. We have a trip planned for Memorial day weekend for about six months now and I sure thought I was going to have to cancel but with a couple days to go we got her going. Just got to put the hitch and bumper back on and tie up some loose wires. I still have some cleaning up of the wiring mess but that can wait till we come back. took a short video and put it on face book, not sure how to do a video on here ???

Jason I couldn't get your link to work. Do we need to be friends with you on Facebook for it to work? Or did you make the video public?

The last build of the 8V-71TA by Detroit with N80 injectors was 400hp and 1200lb/ft torque.
Since I kept the high compression pistons (two piece pistons with tight transit bus rings) we kept the injector to a 7G75 and turbo boost to 15psi. I'm dynoe'd at 375hp and 1125lb/ft torque. A heck of an increase over an N65 natural engine at 304hp and 800lb/ft torque. And yes, torque gets you over the hill. Good Luck, TomC
Great job Jason ,sorry I could help lol but I did send you the books I found 1 for the B400 I am going ship you also when I get home
Scott, Not sure how the video thing works on FB, but send me a friend request if your on there.
Cliff, you did send me one on the B400 and it came in real handy ;) we referred to it quite a bit probably more than the DD book lol
Took it for a short ride last night and things seemed to be working pretty good.

Jason - I understand how you feel after getting out for your first successful run with the new engine in place. After I converted over to a Cummins ISM my first trip was very memorable. You'll enjoy the new found power, cruise control, and most of all satisfaction in your job well done. Enjoy the new found miles per gallon as well.
Thanks for all the encouraging words, Took it into town tonight and got some fuel for the weekend, it ran good, not a power house but not bad. This weekend will be about a 100 mile round trip so that will be a little more of a test.
Jason

Could you not put video on your photobucket account?
