I've heard this is good for gas mileage, and looks kinda cool, so I made an air dam.
Materials: - enough 1/8" aluminum sheet to make seven 1" x 2" L brackets
- fourteen 1/4"-20 stainless cap screws, washers and Nylok nuts
- one length of 4 1/2" x 1/8" vinyl conveyor belting, length ???
- Drill the lower edge of the fascia in the center and then 6 other spots fanning around toward the end of the fascia that the wheel.
- Install the brackets.
- Hold the belting up to the centre bracket and either mark or directly drill through the bracket through the belting. Pull the belting
tight toward the edges and make holes similarly for the other brackets.
- Mark a line at the end of the belting in the profile you want and trim the excess belt (clamping on a straight edge helps).
- Don't be afraid of curb scrapes, it's tough stuff and flexible.
- I rounded the corners with scissors after the picture was taken - looks awesome!

Looks cool.

Let us know of any MPG improvements.

Not everybody has a roll of conveyor belting in their back pocket, so you could probably replace it with plastic lawn edging or vinyl baseboard (my choice as it's sometimes referred to as Cove moulding) :lol:

I only ran one tankful before installing it, so I won't have much data as a baseline, but I will post some #'s. Also, most of my driving is city, so it won't make as big a difference as all highway driving.

i've had a short roll of smooth one side poly laminated industrial belting (60" width) standing in the corner of my garage for 14 years waiting to make a lower front air dam.

i'm a procrastinator. =)

2nd tankful of gas was 41.7 mpg, after lowering the car and installing the air dam. Enough data to be statistically significant? No, but I'm happy anyways.

What size gallon are you using in your calculations?

1 l = .2642 US fluid gallons
1 US fluid gallon = 3.785 l from www.onlineconversion.com

The factor I'm using in my spreadsheet is mpg = 235.22 / litres per 100 km

Fucking MPG newbie. Nobody here uses US gallon. That's almost 50 MPG in imperial, or 5.7 l/100 km. That is exceptional for what you're doing.

"Miles per gallon gasoline equivalent (MPGe or MPGge) is a measure of the average distance traveled per unit of energy consumed. MPGe is used by the U.S. Environmental Protection Agency (EPA) to compare energy consumption of alternative fuel vehicles, plug-in electric vehicles and other advanced technology vehicles with the fuel economy of conventional internal combustion vehicles expressed as miles per US gallon.[1][2]"

^ a b Paul Seredynski (2010-12-21). "Decoding Electric Car MPG: With Kilowatt-Hours, Small Is Beautiful". Edmunds.com. Retrieved 2011-02-17.
^ a b c d "Fuel Economy Label". U.S. Environmental Protection Agency. 2011-02-14 (last updated). Retrieved 2011-02-17.



Why would I use an MPG unit that does not allow me to directly compare what a new vehicle at the dealer will achieve?

Yes, I don't know why you would use a unit of measure never used, or sold in this county, and not the universally accepted method of L/100 km.

I see your point, but ask your dad what kind of mileage he was getting in his '70 1/2 LT1 Z/28, see what units he uses.
When you build a deck, what units do you build it in?

If you ask someone in Europe how far away somewhere is, they'll tell you its 5 km.
If you ask in 'merica, they'll tell you it's 3 miles.
Ask in Canada, and you'll get "It's about 10 minutes from here."

That's what I have to say about that.

Don't get me started now on how apprentices coming out of school with only metric instruction will be able to use lathes & millers graduated in imperial...

And the stainless screws I used to mount the air dam are 1/4"-20.

The Z28's fuel economy would be expressed in MPG. That would be miles per Imperial gallon. A unit of measure that was used in this country, like all the others you alluded to.

Thanks for coming out.

I stand corrected:

"Natural Resources Canada develops the Guide using data collected by Transport Canada's Fuel Consumption Program. The online and print versions list fuel consumption estimates in both litres/100 kilometres and miles/imperial (Canadian) gallon for most light-duty vehicles available for the new model year. A light-duty vehicle is one whose gross weight is less than 3,855 kg (8,500 lb), or a curb weight of less than 2722 kg (6000 lb.)."

From http://www.tc.gc.ca/eng/programs/enviro ... de-629.htm

Please excuse me while I adjourn to draft my post in the '50 mpg' Club thread. This only helps my Gregonomics.

I don't think Gregonomics is required on a sub $2000 car

Apology accepted :lol:
