I have been in the autobody industry for over 30 years and have done a million and one modifications using all kinds of materal. That tee shirt idea is absolutely brilliant!

The plastic filler work seems like a bit much. I would make it smoother with the glass so you don't have to use the filler so much.

At the very least using a polyester primer would be a big help being you don't have to sand out all the spreader marks in the filler. Polyester primer will fill a LOT, you could tape a quarter on your fender and bury it with only a few coats!

Better design

So I was reading around and it said not to block off too much because it will just make the fan come on more often so I redesigned for a little bigger holes... I think this one would be easy with coroplast and some screws...

Whatcha think?

I'd definitely roll the edges, or add chunks of plastic drain pipe, to get the smoothness seen at the edges of the stock opening.

I was wondering if that actually would make a difference or not, thats why the fog light covers stopped at the top of the curve, so the other side of it isn't covered and can be used to flow the air smoother...

Just do it in cardboard or coroplast first like everyone else to see what it takes to come up with something that works.

(Frank's right, cardboard first to prove the mod)

I like it. It has a "look" I haven't really seen on Ecomodder yet. I messed with it a little for fun :

I think that you may hurt more than help in that final idea. Think about this, that ducting thru the middle of the bumper between where the fog lamps go is sort of, not a part of your frontal area. It allows the air to pass under the car, though most goes into the rad and thru the engine compartment. It is allowing "movement" where your design most definately ADDS to the frontal area.

Maybe take advantage of the original design and simply "help" the air to move under the car or thru a better path than it has now (if at all possible)?

MARTINSR -

Yeah, you may be right. Good catch. My (incorrect?) assumption is that what is behind the ducting (aka the radiator and engine parts) also counts as part of the frontal area. I'm just never sure when it comes to this aero-stuff.

I Don't understand because the designs are essentially the same, the top grill is blocked, the fake fog light holes and the middle of the lower grill block, please elaborate if possible

If I'm understanding you, THIS design would be better because it does not block off any part of the smooth design of airflow....

The upper grill block is a definant block and the fake bling light spots can be blocked off too, up to where the smooth design for intake comes in correct?

Ignore the bad picture art, you guys get the point...
