partial boat-tail
(EDIT: preliminary results posted in thread below on Jul. 18.)
Come back, 95metro! Quote:
Constructive feedback welcome! https://images6.theimagehosting.com/a...-partial-8.jpg https://images6.theimagehosting.com/a...-partial-2.jpg https://images6.theimagehosting.com/a...rtial-3.th.jpg Above: what this crappy picture from my antique 1 MP camera intended to show was that Metro95 was right: it doesn't seriously obscure rear vision. The boat-tail cuts of 1/5 of the rear window view, and though you can't tell from this photo, the horizon on level ground is just below the "roof", so full visibility is retained of following traffic. https://images6.theimagehosting.com/a...rtial-4.th.jpg https://images6.theimagehosting.com/a...rtial-5.th.jpg https://images6.theimagehosting.com/a...rtial-6.th.jpg |
Be (very!) curious to see what mpg you get.

This boat tail for you 95metro:D. Metro you so inspired me with this post that I took the rest of my colorplast and put one on casper extending off the roofline. :). I don't know what it will do for aero but went for a test drive on my test loop and came in with 38.2 which is the best every for that loop:D and this was at night with the lights on. I'll be out of town this week but I'll try to get some testing and some pics this weekend. I could tell from my route that it coasts better, but only testing will tell for sure.:cool:

use clear plexiglass . . .

I would think about getting a hatch from a junk yard, and rebuilding fully, then dimple it.

I can visualize a nice row of vgs right in front of where the top drops down at the rear window. ;)
Then right above the taillights a sort of flat fin extending straight out maybe 1.5'. And a row of vgs on the sides...much like the airtabs? In theory...the top vgs would keep the flow more on the rear glass...while the fin would force a high pressure plume of air to the back....preventing the big disturbed vortexes from forming? The side vgs in front of the rounded corners would help to fill in the low pressure also. |
My thoughts while making this:
- compound curves are hard to get right (I got the "roof" of the tail eventually, but not the sides right). |
zpiloto: glad to hear that lunacy is infectious. Hope your immunization is up-to-date for unsolicited public comments.

I like the overall look of your shape. If you could live with the harder corners, you could build a prototype out of coroplast, possibly. If you wanted to do something out of fiberglass, you could get the rounded shape you are looking for.
