Aero My Accord??

Hey guys,

Hello! New here and eager to get started!

I'd like to do some aero mods on my 1994 Accord. So far I have some grill blocks. I used to have a partial undertray but i removed it to do some work. I'd be interested in mods that would give the best improvement in gas mileage. (So far 30 mpg is my record, and that's with trying to hypermile.)

Thanks,

Road Cyclist

Howdy,

Go ahead and introduce yourself on the Introductions page.

Start a Garage page for your Accord. Being able to track your results is huge.

My recommendation just for starters: put that belly pan back.

You should be able to include pix now that you have >5 posts.

Grille block looks pretty sharp. Any air damming going on, or did you skip that in favor of the belly pan? I can't tell because the picture is small, I'm old and my eyes have been crap since second grade.

Sorry for the pic... No air dam yet. I have pipe insulation on the bottom and cardboard on the top grill.

Seems like an air dam and an undertray can't be used at the same time... am i wrong?

They can, but they both address the same problem. A dam diverts are from a problem area, whereas a pan makes the area less problematic.

I recommend you start here: 65+ Vehicle modifications for better fuel economy - EcoModder.com

The tray is a lot more work but will offer greater returns. I have one on my car.

You can install an airdam in a few minutes for a few bucks that will make a positive difference on your fuel economy.

You can install a belly pan in a few hours for a lot more bucks that will make a bigger difference.

I read from someone else that you could get about 80% of a full belly pan's benefit with a well-executed air dam, for a fraction of the pan's cost. Seeing how I have neither, I have no actual experience to speak from, I'm only repeating the wisdom of others.

One thing I have wondered is whether there is a benefit to be had by doing both. In the case of a fully panned car, I strongly doubt you would need as much dam.
