Hey all,
I have a 1994 Ford Explorer, and I've recently been doing a lot of research on these forums and Google on aerodynamics. Considering my Explorer is essentially a "Brick-On-Wheels", I'm attempting to modify the aerodynamics with a shoe-string budget.
Yesterday I removed the roof rack bars (the tracks are still in place), and made a 'nose' for the front that essentially blocks the huge grill opening. I installed that tonight, along with a make-shift air diffuser thing on the back. I think that's the wrong term tho. It's basically a folded piece of duct tape that's taped onto the rear of the roof.
There are still openings in the bumper for air to get to the radiator (but I did tape one up to block it off).
When I get some time, I'm hoping to at least do a partial body pan to help get air around the front differential (which is huge), along with filling in all the gaps I can on the underside to help reduce drag.
I'm looking for help on all of this. I need ideas, constructive criticism, and help with figuring out angles etc. for the best nose design.
Currently, my 'nose' is made from an old poster, some wood for support, and duct tape.
Here's basically what my explorer looked like before (except I re-installed the stock air dam):
And this is what it looks like with the nose:
And this is what that "diffuser" on the rear looks like:
I took these on my phone, so they aren't that great... but they work.
