Bellypan materials

[MetroMPG]

When I had my undertray, I ran coro on the front, sides & rear, AL flashing over the exhaust. I did a cutout in the coro in the front section around the catalytic converter, about 1.5 inches gap. Same observation as Andrew: not a problem, no adverse heat effects.

"Belly pan off" was the "B" state of an A-B test (http://forum.ecomodder.com/showthread.php?t=79 ).

Honestly, I was disheartened by the results, and so not super motivated to reinstall it. Also, winter came. And went. And came again.

I still have all the pieces. It'll be going back on.

Do you have more pictures of that bellypan? What did you use to attach it? It looks very professional.

there is a link to pics in my sig. Its attached to an aluminum frame. The frame is screwed to the car using self tapping screws.

Excellent thanks! I've been looking for a cheap source of thin gauge aluminum for ages.

EDIT:
Is the aluminum sheet also attached to the frame with self taping screws? It almost looks like rivits from the pics but I'm not sure. Thats one of the best solutions I've ever seen.

EDIT 2:
Did you see an appreciable gain in fuel economy with the extra air dam over the belly pan alone or were those 2 separate setups at different times?
thanks

From those who have done belly pans, and wheel skirts on rear (& front) - I would like to ask for some Instructors, Assistants, Volunteers, or Helpers for my little event on April 10, 2011 - The First electricfly Event - "Electricfly Aero Mods" - Fuel Economy, Hypermiling, EcoModding News and Forum - EcoModder.com - Just a quick little idea recently put together to have a little gathering on a sunday afternoon!

With an OEM bellypan I'd be a bit more concerned. I'm sure the fit and finish would be a bit tighter, but look at the Lotus Elise bellypan (there's a thread and everything.) It has NACA ducts in it, no CO buildup there.

I think we all need access to a Z-Corp Hand Scanner type of device, so as to make a support structure that realy is flat - no matter if we use cloroplast, aluminum, or vinyl skins on our pan! It would allow modeling the actual underside of the car, and allow for structure to be designed to fit the actual car's high and low points but still give a straight line flat for the pan!

Scanner Video - in action!.

When used with a 3D Printer - we could get some very fine fitting results worked up, and even make pans and supports for sale to other ecomodders, even if just the scan files or CAD files were made available!

It would be nice to have an EcoModder Group Display - if not at this years EV Fest - then for Next years show! Aero Caps, Belly Pans, EV Conversions, Boat Tails, Front Skirts and Air Damns - to name a few exhibit ideas!
