I took some pics but can't get them out of the camera.

front surface of the visor is the exact angle or damn near exact as the windshield.

and from the looks the distance between the edge of the visor and the windshield is the same as the exit holes size.

Chaz -

Thought you might be interested in something "The Factory" did with a bus model in terms of a visor.  This is an MCI MC-6.  Have only found one pic that shows the roof above the windshield, and it's a poor photo, so I didn't scan it.  Anyway, look closely at the photo I have posted.  The dark spots on either side of the center "Michigan Marker" lights are the fleet number.  On the roof there are longitudinally-oriented slotted vents running from fleet number to fleet number, roughly corresponding to that little "hump" in the trim, to allow the air trapped by the visor to escape.

Did these contribute to increased fuel mileage??  As big as this monster was in it's day (1969 - 1970), and the thirsty 12V71 that powered it initially, it was probably a moot point!

FWIW & HTH. . .

Thanx Russ.
  That is probably a more functional visor as for the sun, as you noted. Looks pretty cool, but I think I am going to try to get some aero out of it by making it slant down more and a bit longer. Plus I think I can make it blend in a little better with the lines of the bus also.
  I'm not sure I will put openings at the rear where the visor meets the bus. I am looking more at possibly louvering it. But until I do up a sketch or two, I won't know. The louvers may take away from it.  ???
  Thanx again for digging around for a photo for me!!!!

I am surprised that someone has not posted a photo of the Eagle with an extended snout for your viewing pleasure. I do not have a photo of it, but I saw it while at Dallas's last get together. It extended out about ten feet I believe from where the normal front end of the Eagle was and as I recall you could not see the end of it from the drivers seat. Must really be a bitch trying to make a right hand turn into a two lane street. Maybe impossible. Hopefully Gary of someone will post a photo for you.

Richard,
   Are you talking about "Home Grown Diesel"?  I am familiar with that bus. He's a helluva nice guy and I want to pick his brain one of these days on WVO. I just have too many irons in the fire right now.
  I actually asked him to weigh in if he had any info he thought i could use.
  But I want it stay -maybe- a little more original.  ;)

This one? It's definitely different! There is another one that I am thinking of that is not so outrageous. I'll see if I can find a picture of it too.

Yep. Thats the one. Really a lot of work and thought went into this beauty.

There is another one that I am thinking of that retains more of the Eagle look. It has a fiberglass car type nose on it and the bus is smooth sided. The pictures I have seen are from a show and the bus is in primer.

Finally found that other picture I was looking for. It was right here on the forum in the photo topic.

Not really an airdam but more streamlined in the front anyway...

Hey Thanx Songman! Pretty sleek looking bus. But I think it could still use a damn. Opps, "air dam".  ;)   :D  lol
  I think the way the top is stair-stepped on a Buffalo makes it a bit more stream lined. Is it enough to make a difference? Only a wind tunnel can tell. But I still like the idea of a dam....even if its just for looks.
  Thanx again for looking up that pic.

    To air is human, to have a bus......... DIVINE!!!

the Step on a Buff is NOT aerodynamically efficient

If you want to Aero your Buff

Step One:  Put an Eagle cap on the front of it.
Step two: Take stuff off the roof
Step three: Don't put a cap on the back
Step four: Ground effects, but never drive the bus on anything but highway because you will rip them off
Step five:  Put that bullet train nose add on on the front
