These are heavy beasts no Doubt and built considerably stronger than their Transit Counter Parts................These engines are at 277 HP which is a pretty mild setting: likely have much smaller injectors than what you would find in an MCI or an Eagle.
Of course you are moving a Brick.........so temperatures, terrain, weight and wind are all variables. So what kind of Mileage might you expect?
Fact of the matter is you never know till you try. Some questions relevant to this would be specifically to ask what the ratio is. I have learned that these have the MT644 Alison, but closer inspection appears to show that they may also have the Stone Bennet air shift............One of the questions not asked thus far is if these are DDEC 1 or 2 or if they are mechanical.
Really need to ask a lot of questions with regard these Coaches. Yes they will have underbelly storage. And yes they will have far better ground clearance than any Highway Coach. Are they air ride or are they Sprung? Another question not asked or answered.
I'm not particularly interested in owning a 40 foot Bus: If I were I would look very carefully at these as being a potential winner. California Coaches born and bred. Whether the engine is mechanical or electronic it surely offers tremendous potential for becoming fairly efficient. I see no reason, with sane driving that you shouldn't be able to pull 10 MPG from this engine. And as well for those not so concerned with thrift, this engine can fairly easily be "tuned" to 350 HP..........300 would probably be the max with the current transmission.........which can handle roughly 800 ft. lbs. torque......I know that the Super II used the HT740 coupled to their 6V92....so I'm not sure that the district saying these are the MT series is correct. The District was not responsible for the AD PS was, and they have done a lousy job. Photos loaded upside down and sideways, misleading and incomplete information. But
I look at this way: Of all the modern School buses out there especially for those looking to build out, You would be hard pressed to find another schoolie as stoutly built as these Phantoms.............
If I were looking for something to build out I would consider these very seriously. I would also make it my job to find out what is really going on with them. There are so many omissions that require answers. But this Auction for the one who takes the time to get to the bottom of it all, could get you a Bus far superior to any Bluebird or Thomas. My opinion. More importantly, because of the scarcity of information, and because of the lack of awareness, generally of these Phantoms, you might be able to steal one.
