Hi I am new to the forum

[Scott & Heather]

Everyone talks about how great the 6v92 is but my 32,000 lb 9 is slooooow. Turbo too. I need more power. I'm embarrassed how much little hills slow me down. Seriously.

Scott,

I just scaled my 4905 for the first time this summer, and it came in at 23,900.  The 8V71N manages to push it pretty well, but when I add the 4000lb toad, I can definitely tell it is back there.  The difference between my rig and yours is that I never have any place I need to be in a given time, so slooooooowwww is just fine!

400 hp Cummins ISM would resolve that problem - I know you're upgrading to your new bus with 8v92 so this doesn't really apply to you anymore

The 6v92ta I had in my bus before the Cummins was slow also, got poor fuel mileage, and always had to be watched for over heating in the summer.  No more!

You never heard me say how great a 6v92 was but they have their place it is a good engine for a 35 ft bus lol you should drive a 45 ft Eagle with a 6v92 then you would know what under power is   Scott what hp is your engine I don't recall MCI ever setting the 6v92 over 288 hp,330 hp was the Eagle setting and were ok in the 40 ft model 10's,15 and 20

My 6V92TA is a lot better now with a few improvements I have done over the last few years. 9G90 injectors timed at 1.46", TV7512 turbo, Ecco air filter 1200 cfm, straight exhaust with resonator, bigger squirrel cage fans with smaller pulley from an MC9. That is, in theory, 350 hp and 1020 ft/lb of torque. I take the covers off once a year and run the rack, and make sure everything is right. It pays off in the satisfaction of a good running machine. Even pulling the car on this trip, (guessing 31000 lbs), we go up the hills with the trucks, passing half of the loaded ones. Not all 6V92 engines are the same. If mine broke, I would probably just fix it. No room for a 4 stroke in a MC5.

That is true JC I have set a couple to the 400 hp fire truck settings they do good but the fuel mileage took a big hit 

[Barn Owl]

it is a good engine for a 35 ft bus/quote]

Yes it is. In a 4106 it makes it a different machine, even more so at 10,000 feet.

[lostagain]

My fuel mileage is not bad at about 7.5 m/USgal.

JC your gear change helped you a lot you set a 6v92 @ 400 hp with 3:73 they drop to around 5 I bet it would be less than 5 mpg with 4:10 gears

    Thanks to everyone for looking and welcoming us to the forum. This is the best conversion forum out there by far. The previous owner had over 30 copies of the bus conversion magazine in the bus. Also they left every thing except their personal items. The cupboards are full of dishes, pans, coffee pots, etc. Now the good things they left are cases of fuel, 4 new air filters, 2 cases oil filters, cartridge and spin on and a spin on oil adapter. Three new belts.Wheel chocks, ramps, 4 new 20 ton jacks, tow strap and all the parts that were stripped off the bus before the roof was raised. Numerous tools, stainless steel fittings, gauges, bar b q and stand. All the electrical cords with different amp connectors, water and sewer hoses. All the engine hoses were replaced with new ones, new stainless steel fittings and gauges. There is 2 new starter batteries and 2 new RV batteries. The previous owner had a leveling valve not working so he replaced all 4 and even bought a spare. This is an example of how the bus was maintained and was one selling points for us to have confidence driving down the road.
    There is also a manual for everything that that is on the bus including the bus, engine and transmission. The manuals stack  almost 2 feet high. I also have a photo album from the time the it was a tour bus, to the complete roof cutting, welding, interior work, the final painting and camping pictures. Things that we really like besides the raised roof there is a 26 foot awning and individual window awnings. The 2 air conditioners/heaters. A fresh air vent on the roof at the back of the bus for helping cool the engine. the large back up lights at the back and one on the side built in under the awning. Just cant wait for this snow to go away and start camping in the spring.

   Here is a couple more pictures of the inside. All the wood work is 1 inch teak.

[luvrbus]

How many of the MCI 2 were ever built anybody know for sure I thought it was just prototype,I did see 1 of the 26  MCI 1 that were built

[Ed Hackenbruch]

 From the MCI 1 to the MCI 4 they made a total of 196, all of which were sold in Canada.
