Best guess is that they have/had about twice the rating of the bus 671N mill sooosssss....about 195 or 200 times 2 equals around 395 to 400 hp.
Or....they could have as much as 238 hp times 2 or 476 hp. Torque would also be between 1150 and 1200 foot pounds of axle snapping twist.
But....the neatest thing about the 12V71 is that they sound sooooossss cool with a deep distinct roar. Can one imagine a twin turbo 12V71TI......
.....with a factory rating of around 550 HP? Wonder how one could keep clutches and trannies alive? Good luck with your Canadian hotrod. Henry. |

Not enough?
Wait--that's the power rating of ALL engines!
12V71 in a coach sounds impressive. |

I think it's been posted here before but:

this is all the engine measurement, weights, and ratings. |

I think John is referring to the MC-6, which was built in 1969-1970, and only 100 were produced. They originally came from the factory with the 12V71 and the common four-speed Spicer.
Greyhound spent a fortune replacing clutches and drive shafts, because drivers couldn't (or wouldn't) be gentle with the tremendous torque output of the 12V (IIRC, it's about 1300 ft/lbs at 1300 rpm). Finally, the MC-6s that were assigned to the USA had the 12Vs pulled and 8V71TAs with the HT740 were installed. Only about 20 of the orignal 100 kept the 12Vs, and they were all in Canada. There are very few MC-6s floating around nowdays, most have been scrapped.
The MC-6 was the first 102", wide-body highway coach, but Greyhound wasn't successful lobbying the powers that be to allow it everywhere, so it's use was restricted. . . It was literally "slightly ahead of it's time".
I'm not aware of any late-model coaches using the 12V, most are using the S-60 nowdays.
