The guy is in NC and he built mine in fiberglass off of my original bumper. It probably weighs 3-4 lbs tops. I can get you hooked up if you need one.

Thanks David... Pm me his info and I'll look into it... At the moment, I'm looking into doing it myself, but it would be nice to see if it's worth the time to do it, or if I should just buy one...

Doug... Cool

I had lost the original link long ago but kinda remembered the name......Google to the rescue. Laughing

There might be an updated version of this out there by now. But my computer has enough trouble running the older V 1 & 2 on dial up so I never went looking for anything newer or "more gooder". It's simple but clunky. You don't get actual air speed numbers, just sliders to play with air speed, viscosity, etc, etc. It would be much easier to draw shapes with a pen vs the mouse.

Crap, if I had been thinking I would have also drawn the outline as if the bed wasn't covered and had a closed tailgate......damn brain fart. Mad

I like to fly low in the Desert, with an open bed, airflow is turbulent though predominately flowing towards the cab at speeds from about 60 to 125. Above that point air flow reversed, however the bed area was low pressure. The only laminar air I found was about 10 inches higher then the cab above the tail gate. Sheetmetal was mid 70's, low pressure in the bed area would start unloading the rear tires at about 130 and nobody wanted to go over 140. You might not notice the unload on pavement but in dirt, the rear tires would spin, you could see it in the Tach almost before you could feel it.
Do you actually get enough air flow, in the right direction at bed height to do anything? Is it the bed cover that you feel is necessary?

130 in dirt !!!!! Shocked

You are insane. You will fit in fine here. What a Face

With the bed at the top of the sides, and at the bed floor. Note that the air flow is going to the back wall of the cab, so if you are mounting coolers there aim the fans the right way...

Ever wonder what that bug deflector did to the aero...

ThndrChkn on September 29th 2009, 12:17 pm

That's very interesting... The bug deflector is kind of a shocker... I was always "told" they helped push airflow over the cab... scratch

Doug, the front bumper for my truck came from a man in NC. I went thru Wayne James to get it. It cost about $275 I think. I am very happy with it and the chassis man is going to shorten it 5" because factory Ford bumpers stick out past the fenders too far. If you need more info, let me know.

I'll call Wayne James and see if I can get a phone #. He has his name on the bumper, but no #.

very nice ride!!

David Cole on November 22nd 2009, 9:30 am

David,

Yesterday at ORSCA qualifying at Steele there was a truck similar to yours. Running the 5.0 class. He was straight as a string on every pass. Only had just a little lip on his bed cover. I know you will be faster than 5.0, but you might not NEED a wing.

very interesting on the wing deal building the my little ranger now want be very fast to start with hoping on high 6's in the 1/8 to start with but after some time on track going bigger and more hp just wondering if the wing will help later on don't think i will need one to start with but might go ahead and weld something to the back to hold one while i got it apart before painting the chassie
