But that bird is 9 foot 8 inches wide.  Wider than any legal vehicle.  I wonder if you have to have a wide load caravan everytime you drive it?

SSshhh! That's a minor detail that if ya don't tell anyone they won't notice! Besides being what it is folks will be paying more attention to other things than to as how wide it is! Also being round it's only that wide in a small part of it so it don't count! OK, OK have I BS's that one thru? LOL !

Chaz,

If you are going to use some belting as an airdam, have you thought about installing it as a curve under the bus as opposed to a flat face across the front?  possibly even in a V? or something to the effect?  Just a thought.

Thanx Skihor!!!!! Good stuff!!
 
And you took the thoughts right out of my mind NewBee!!!!!!!!!!!!!! Grin I think there may be something to this. I think I still want to do an airdam, if for nothing else than the "cool factor".  Grin But I'm also thinking some wedge type design under the bus may have some impact.
 Oh to have a pocket full of money and a wind tunnel at my disposal!!  Wink Cheesy But then, when I get to that part, I may try the ribbons taped to the bus and and a car along side to see what happens. I just need to find the time.
 
  Thanx guys,
     Chaz

Chaz, if you get an accurate fuel meter, you can see the effect of drag changes directly in your fuel consumption.

The hard part is setting up your tests so that you get a fair comparison.

For what it's worth.

Good thought Tom. I'm not sure how they work, but it's my guess that it would be complicated. Especially since fuel goes back to the tank also. Maybe I can find something like that from a Semi boneyard.   Huh

  Fuelin around,

Chaz come on down to the bus bash! I can't guarantee a wind tunnel, but I can assure you of a lot of wind! (from all the bus lies stories being told!)

Yeah, Jerry has been tempting me!!! And it's killin me!!! Tongue  But I just had a weekend off last weekend so now I'm kinda behind the 8 ball. (I tend to work all the time to stay afloat) I need to try to afford my new hobby, even tho that means not being able to play with it.  Cry
  But hopefully we will be able to make one in the near future. I think the next big endeavor will be WVO so I can get a break on fuel costs.
 
  Easy on all that wind down there!

Chaz, the fuel flow meters for diesels use two sensors, one for the supply and one for the return. The meter deducts one from the other.

I don't think that they are very complicated, but they tend to be pricey.

You might look at used small airplane equipement because most use some kind of flow meter.

They are very useful in boats, as well, to set RPM for best fuel economy.

For what it's worth.
