Aerohead, any areas you are going to change as a result of the testing?

I've thought of:
*the custom,plan-tapered bed
*detail the belly
*Get the wheel fairings on
*Do something about the mirrors
*Do an active diffuser which I can lower on the highway
*Close up the gaps along the boat tail sides
*Maybe ventilated MOONs
*New stinger and boat tail to fit the custom bed
*Play around under the hood with respect to ductwork downstream of the radiator
I sure need to work on my house.Any of the members who've been there will probably agree.

At Bonneville they let the guys delete the mirrors entirely.
If things go right nobody is overtaking you from the rear.

It wasn't the testing that did in the front skirt. Here's what we talked anout at the Salt Flats Cafe. At least what I got done before Wings3D locked up. It replaces the top hinge with a 4-bar arrangement.

That was funnier that most content on humor sites. Also, more believable.

The way the streamline hugs the side, around the bumper and passing the front wheel skirt, is cool. The movement over the hood, windshield, and roof was striking--the flow just hugs the surface of the body. And it loved your lingering use of the wand to "see" the wake at the aft end of the truck. Seejng the separation line and that stagnation point of sorts under the aft end was fun too. Fully worth it. Every penny.

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.

First thing that popped into my head after knowing that the test was over and read some of the results was: How did it match your predictions? What did you think the CD would be? Based on what? Does the measured number match your predictions based on fuel economy? Coastdown testing? Tuft testing? Don't know that you had any specific predictions for this exact configuration, but you still must have had a number in your head that you thought it would do, right?

Your list of improvements seems to go after small stuff. Are there any BIG things that you can't really go after? Plan taper on the bed may be larger than I'm thinking? Maybe ride height? Lots of little stuff adding up?

I selfishly vote for a large vehicle to the wind tunnel next. Some sort of RV or box truck. Love to copy the Dryden van and try a few different tails.

I'd be in for a no-drag sticker and maybe a magnet if there are any extras. $$$

Video's great! Thanks for posting. I see there are also a couple new images to crop for wallpapers.

Looks to me like you'd need a bigger tunnel for that.
