Dude. This thread is full of so much awesome. I'm gonna have to show the kids tomorrow

How big of an exhaust pipe to flow for 3600hp?

Two of these.


The catalyst in this one broke free, and spun until enough of the top had been closed off that the engine wouldnt even idle. The top rubbed against the x that holds it in place.

For size reference, that's my size 13 boot next to it.

Underside of cab car that's been lifted about 6 feet in the air.

yeah 2 stroke detroits while not the most fuel efficient are STUPID reliable so long as you dont over heat them and burn up the water jacket/Cylinder liner seals at the bottom of the bore. They really hate coolant in the oil, it takes a very small amount in the oil pan to spin a bearing or 4. The nice thing is though they were made for so long they are very cheap to rebuild parts wise, and 8V92 (the last of the over the road and bus 2 strokes built into the mid 90's) are about 150-160 bucks a hole to rebuild, so long as your crank is not scored and shot to hell.....

That is one big ass Detroit, I didnt know they were still in service in Loco's even anymore dude to fuel consumption and emissions regs..

They don't manufacture then anymore, but still in use because of the good numbers and stupid reliability. I'll snap a photo of one of the block casting dates. I'm pretty sure they are all 30 years old or more now. The blocks that is, internals are obviously newer, and they redesigned the induction system to go to the turbo setup. Oh, and EFI helps too.

Honestly, even though these mp36c's are 2010 model year locomotive's, they are a mix mash of old parts updated with new technology. I had to replace a couple dynamic brake fans for a recall per say, the casting dates on the ones coming out and going back in were in the 1970 range.

Speaking of emissions, next photo idea. Biggest catalytic converter I've seen in person. They are about 2 feet in diameter each smack on top of the exhaust. We have to remove and clean them out on occasion. I'll snag a photo next time I'm playing around on the roof of one.

There ae 2 types of super charger roots and centralfugal both are supper chargers and both are referred to as blowers, but when you think of a blower you generally picture a roots type like 2 storke detroit diesles need to function properly.

[payney8]

Not a supercharger, it's a blower very different.

So much displacement, in the morning after being off all night, you have to open bleeder valves to push out condensation before running the engine. At least I had to on our switching loco. 2500 hp and in-measurable amounts of torque, all at your finger tips.

Still do, but we have the luxury of working with the Aston Martin of locos lol. Ours do the purging for us.

Just a 3 month service today. Change all of these out.

Came here for the turbos

Will not leave disappointed

Do all trains use the diesel engines to power electric motors?

yuppers unless they are hooked up to the power grid and are electric only via a 3rd rail power supply or over head lines with a pole and a glide surface kinda like a bumper car.


That is one big ass Detroit, I didnt know they were still in service in Loco's even anymore dude to fuel consumption and emissions regs. Fun fact, All detroit 2 strokes need a supper charger to operate and scavenge correctly.
