At some point I may have some A-B-A comparisons with a faired vs unfaired electric recumbent trike. Winter weather makes reliable comparisons difficult though.

Thanks to those people who have written to me.

If you haven't but are considering doing so, I'd encourage you to.

I think that this is a once in lifetime opportunity to see your work and car in a 'proper' book ie one that will be in libraries all around the world for perhaps the next 100+ years!

Have you heard from aerohead? He's only on the forum on the weekends. I will PM him if you don't. You two need to talk.

Jaguar has just told me that they are making an XE Jag available to me for on-road aero testing.

This is good news - it will be fascinating to see how the on-road testing stacks up against the excellent technical presentation Jaguar's chief aerodynamicist sent me (that, incidentally, includes lots of CFD).

I have many hrs of un edited video and stills of snow and tuft testing, of my Aero Tonto.

For truck mods ,I must retain the trucks ability to be a truck so function over form.



Ps metro its "flipping" the pictures "agen"

Cool project. There are lots of possibilities here at EM.

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.

Phil Knox(AKA Aerohead) 2nd that nomination.
As driven to Darco.



Without function form is void.

My 91.5 D250 Johna started at 18.6 avg mpg (16.xx low- 23.1high)
Added the Aero Tonto and it bumped to 24avg(16low towing - 29.3 high) .
When i drop to 22mpg I am looking for something broken on my truck or a low tire.
It must still be a truck ... I define a truck as a rig that can; 1 carrie a full size fridge standing up, 2 carrie 1 cord of green oak(3000lbs per National Forest Wood permits) , 3 tow a trailer of at least 10,000lbs a minimum of 1000mi , as daily driven(nothing to remove to preform the task)Other wise its just a glorified station wagon with limited seating.
The cap is also desined to act as a fairing when towing high profile trailers ( box, RV TT, or 5th wheel).
now that the wind tunnle data is in, and I have almost 100k mi of data with the Aero Tonto. I can start adding more of the total kit, to reach my ambitious goal of 40mpg.
Yes my fule log is out of date... odo broke Dec '16 but periodically check with GPS .

Thanks for the posts but if you want to be in the book, you need to:

1. Email me a couple of high res photos and a short description of what you've done, and how you tested the results. julianedgar1 at gmail.com

2. I'll get back to you to let you know if I am interested. (I hope I will be, but I might already have examples that cover the same ground, etc.)

3. I'll then ask you to write a more detailed description, or provide more pics, eg a step by step, or testing of different versions, etc

4. You will be mentioned by name in the book, as will EcoModder

Basically, I need to see in my in-box the contribution you want to make eg I cannot tell from photos posted on a web discussion group whether they'll be sharp enough and large enough to use in print.

I've just finished a book on home car workshops and I featured three home workshops from around the world, so I am certainly happy to include content that shows off what people have done.

Too late for your last book, and it sold off decades ago; but here is the garage I designed for my parent's geodesic dome on the Oregon coast in 1980:



It's an 18x22ft octagon that housed a hi-top camper van so it has a 9ft high single-wide door and ample workspace on either side of the vehicle. It's not a geodesic dome. Technically it is an expanded zonohedron.

edit:
By the way, built for the Oregon coast, that's a 100mph cruising speed garage.
