AeroRanger (brother to AeroJeep) boat-tail - Fuel Economy, Hypermiling, EcoModding News and Forum

Just put the boattail on yesterday. I haven't driven enough miles to get a decent fill-up yet, but it sure drives differently. I normally coast down a hill, between exact points, and go from 55 mph to 52/53 depending on the headwind (always a headwind there). Last night I hit the coast at 55 and came out at 57 mph. Today, the headwind was fierce and I came out at 55. Definitely a longer coast. I'll have to do a test run soon. The temps are dropping a bit here in Jackson, WY. I'm hoping that won't affect the results much.

Thanks Big Dave, I went to fill it up this morning to start with a clean slate and a ring of people surrounded me inquiring. People were actually stoked this time too, which was cool (I think because they think I'm racing it, looks like it should be fast but the engine is only 2.3L). A lot of people ask if it's electric too. Hoping for mid-50s hwy mpg. We'll see this weekend.

Looking GREAT!

Please do some testing and post up the data, I will add it to the wiki.
For the wiki I also would like cost and time for the mod

Thanks and keep up the good work!

Thanks Weather Spotter. In total, everything costs $600 (for everything on the truck, half that for the boattail). I probably only needed to spend 500 though. The screws, bolts, nuts, & washers really add up. The polycarbonate was like $120 too.
Time wise, my head was constantly working on it all day for weeks. The boattail took probably 12 hours of hands on time. The aerotopper twice that (no power tools then).

Thanks for that data, I will add it to the wiki once you get MPG results.

NICE!!

I am impressed.

I took the liberty of browsing through the other pictures in that gallery and the VW looks interesting. Is there another thread about it?
