Well folks, I decided in light of the wedding I have to go to in MN this weekend, and the lack of time I had to prepare, It's time to get down and dirty with the mods. For a while now I've been wanting to block off those fog lamp and tow hook holes. So a little black wrapping paper and some clear tape and we are in business. Going to take it for a test drive to work this evening to see if it's all going to stay on. Hopefully it will give me an idea if it's a mod worth the effort to make permanent. Oh, BTW the multi colored bumper is due to the fact that it was raining when I took the pics.

467.2miles on one tank at 25.09MPG's
I'm back from the wedding in Minnesota and boy was it a blast(The driving that is). Managed to hit my highest tank to date at 467.2miles and 25.09MPG's, that's 87.2miles farther than this baby should be able to go and I still had 1.4 gallons to left. I would say that covering over those tow hook and fog lamp holes is well worth the effort. I noticed an immediate reduction in wind noise and enjoyed watching the MPG's hit 50+ headed down hills.

Here's one leg of the trip from a rest stop to the south end of Minneapolis. The scan gauge in the end was reading a few % high so compensating for that it should read about 27.55MPG's.

Here is my unmodified Cherokee's fuel log: ecomodder.com/forum/em-fuel-log.php?vehicleid=2104

I try to drive as efficiently as possible.

Outstanding work man, I don't know if I would be brave enough to push my tank that far. I find it hard to squeeze more than 18.25 gallons in (which means I'm not draining it all the way and that's filling the filler neck too). I just moved to GA for a while and am hating having to run my AC all the time just to keep the interior tolerable. I've been walking/bicycling as much as I can to keep from using the gas pig, but it's been hard with the heat lately.

heck, depending on your job you could even jog to work and just carry a change of clothes in a small backpack

Ok, so I'm considering rear wheel deflectors and was wondering if the group found them to be useful and what design works best? I did some digging in the search and didn't really find the answer so I figured I would test everyones memory. The picture below is what I have to work with location wise, I listed a few of the designs that popped in to my head reguarding the configuration. Let me know what you think is best and please chime in if there is a better choice.

Ok, so I decided to go with option one and try to channel the air between the tires so they are angled in slightly. Figured it might reduce the wake behind the car a bit if you reduce the air being pushed out. Right now it looks kind of fugly, but I plan on trimming them up a bit to style them and give them a nice coat of paint to blend it in. Just figured I would get it installed and see what it does.
