Front air dam

Has anyone tried a front air dam?? Seen any significant mileage increase?

Seems to me it could be made fairly cheaply

Time is of the essence to me, I am building a grill block and may not have time to construct a dam for a month or more. If I do I will post the increase or decrease which ever the case may be.

Need to spend time with my kids before they grow up, thats more important than gas mileage although I just CANT let go of increasing my mileage. (more money for kids college fund through fuel savings) :thumb

I've seen a few on the forum here, I think BB has one, I think there is also one made from edging material :dunno around here somewhere. Will have to search the links up later, if this isn't filled in by then :)

I was lucky. My kids used to enjoy helping me work on cars. Just little stuff like keeping the tools in order. My daughter used to have a little chair and a couple of rags and liked to clean tools and keep them in order. I used to have old primed pick up and in the summer they used to like to paint it with a brush and a bucket of water. The water would steam off and they thought that was fun. Last year I was welding a 4 inch pipe and my son asked if he could finish it. Sure, I said, if you can do it better. He did. :banana :banana :banana But you are very smart to spend time with your children. They go up very very fast

Please just call me; "Schultz"

I have one. I will post pics soon, snow all over here.
Made from the lower spoiler of a mid 90's Chevrolet Blazer S10.
Dam# near a perfect fit.
I am getting ready to pull it off for the winter. It keeps acting like a dozer blade in the snow. (we don't get snow here, got 8 inches last weekend, calling for more this weekend)
Mileage increase? maybe 5%. No true A-B-A-B testing to verify. Mileage log shows increase, but also some decrease as well.
I went to 13 inch wide tires from 12 inch skinny tires at the same time. I believe they balanced each other out.
Next summer it is coming off and I will replace it with a full under-body panel.
Hope this helps.

I got the edging material, 3 feet of 1"x3/16(?)" aluminum, something bendable (no vice), some bolts/round head screws and Nylock nuts/washers for maybe $20-$25 total. Made little "L" brackets, drilled a bunch of holes. I did not want to drill through the Le Bra and was not entirely sure this would work. Turns out it's break-away in snow and that's a good thing. ;) Well, I like the way it looks and I believe it contributes to better gas mileage. At least in theory, eh.

I was looking at ecomodder.com and the belly pan project, tho not perfect, netted ~2.5% or there abouts. The last post however noted that the various projects had each been under 3% but do 4 of them and I would conservatively say you got a 10% increase or maybe 5-6 mpg.

College? Start collecting Metros to give to them as graduation gifts? ^o)
One Crazy Summer is a silly movie with John Cusack and Demi Moore where 'Hoops' gets a surprise graduation gift. Rated 6.0/10.0 & is PG.

I had read about the belly pan on ecommoder also. The only scrap metal I could find to do this would probably add 50 pounds to the car which would likely offset the gain in aerodynamics. Who really knows? If I ever have time to try it I will.

Schultz i know what you mean about snow I am half way between Williamsburg and Richmond and we got hammered, almost a foot of snow. Hey the lawn tractor (mowing deck removed) and an old piece of plywood made one ripping cool "snowmobile" though :rocker :rocker You would have had to see it to believe it. Long as it falls on the weekends only BRING IT ON!!! My kids would back me up on that statement.
