Re power

[Beesme]

How much power would I gain in my 4106 by installing a re manufactured 6v92t in my bus from an awesome running 8v71? I'm really thinking of other busses because of unknown motor . Even though mine runs @ 60lbs of oil psi but slow on big hills...I do love my bus but the price of other busses today omg.... You know what I'm sayin ? And how bout right hand motors if I were to find the right deal is it worth changing to left hand rotation or wait for the right left hand rotation motor......

And does my v730 bolt right up to 6v92? Do I need attention to my radiators ? I may dump a lot of $ at this ole girl I am attached.....

If I get the time and dollars there will be a series 50 in the back of huggy.

Gets rid of the heating problems if you hop up the 6v92.

Gets better fuel mileage and about the same power.

The major problem is gearing the 04 and 06 coaches  as the 50 does not like to turn the rpm of a 2 stroke.

Bruce -

Your stock 8V71 in normal bus trim runs at about 275 hp and around 770 ft/lbs of torque.

The common 6V92TA swap frequently is tuned to 350 hp and about 1100 ft/lbs of torque.

I know of a 4106 owner who's got an 8V71TA in his coach, tuned for 375 hp and 1200 ft/lbs of torque.

If you want to go the S-50 route like Uncle Ned mentioned, you'd need to find a VR-730 or VR-731 to handle the RH rotation of the four-cycle engine.

FWIW & HTH. . .

There is a big mis understanding about RPM's of a 8V-71 and a Series 50. The stock 8V-71 with 55 or 60 injectors produced maximum torque at 1200rpm-so does the Series 50. 8V-71 is rated at 2100rpm with easily turning up to 2,300rpm-so does the Series 50. What the Series 50 will give you is nearly 10mpg. If you were trying for a million mile engine, I'd say running the Series 50 at a higher RPM (both engines are rated at 1,800rpm for continuous duty) won't make much difference with our type of running.
I hopped up my 8V-71 to 375hp and 1125lb/ft torque. But had to change the muffler, radiator, add the air to air intercooler, air cleaner, extra transmission cooler, add misters to the radiator, etc.
The Series 50 will run very cool. So cool, that when Greyhound changed their 8's from 6V-92TA to the Series 50, they eliminated one of the coolant radiators and replaced it with the air to air intercooler. Good Luck, TomC

Thanx so much for input everyone . I do like uncle Ned's s 50 suggestion . I was under the impression that it was unattainable . So what is next step and where is best place 2 start looking for pieces of puzzle . I would like to do while bus is down for winter . I really love my bus and if I could put today's technology it would be so great!!!

The last time I came through Lakeland Fl.   John Silvers bus repair had several transits there with series 50 in them.

That is where i would start, there or at Gene Russell's In NC.

On the West Coast, look up CCW (complete coach works) in Riverside Ca, ample supply of 50 series engines and B400 trannies.

There's a guy that put a Series 50 in a Silversides (can't remember who).

Bernie at Bernhards Bus Repair in PA did the S50 transplant in the Silverside.  The story is on his website, must have cost a fortune.  BTW, Greyhound did not repower MC8's or 9's with the S50, they bought MC12's with the S50 installed from the factory.

Will a 8.3 Cummings from a nova fit

[luvrbus]

Boomer, Stewart and Stevenson did do some re powers on MCI 9's and 12's I was at the shop visiting Cole while they doing those ,he said they 12's though, they had only did one 9 he told me

Will a 8.3 Cummings from a nova fit

     I looked at a particular installation in a Nova before I bought the donor Gillig that my Cummins 8.3 (ISC) with B400 is from.  That Nova has a sideways installation that would have been very difficult (my own take was completely impractical but if someone knows some details that would make it possible, please chime it - also, are there different engine layouts in Novas?) to move to a bus with a straight-down-the-middle drive line powertrain.  Certainly the diagonal drive rear axle would have been difficult/impossible to use.
     AFAIK, the sideways slant Novas are only models of Nova buses that the Charlotte NC transit has ever had.  Again, I don't know the full range of what Nova models are out there.

Bruce and Uncle Ned,

I've got just what you need: 1994 RTS with a low mileage Series 50 w/V731. Runs Great. I'll make you a deal on the whole bus and you'll have everything you need to complete the conversion.

The bus has 5 year old 12x22.5 tires under it and 4 new group 31 batteries....ready to drive home.

PM me if interested.

Bob
