I've made a few posts here already, but I thought I should say Hi first!
I'm a college student in New York (no, not the city). I heard about hypermiling from the Grist.org online magazine I read. I found articles that made hypermilers sound like crazy fools and thought "hey, I should read more about that!" After finding out that the media just likes to make hypermilers sound like tailgating freaks, I realized I was already driving pretty well.
My Subaru was a hand-me-down originally getting 23mpg by my calculations. But that's when I was driving 15mph above the speed limit all the time. The past year I've been accelerating slower, doing a small amount of pulse and glide, and some EOC on major hills (some over 8 miles).
My plan for modifications is not to spend much money. As much as a ScanGauge would be great, I just don't drive often enough right now to justify a purchase like that. I'm currently working on a front air dam, and a boat tail. I hope to finish those soon and then work on rear wheel skirts.
I'm glad to have found a community of people just as crazy as me about this kind of stuff!
I've been taking lessons since late spring. It's a great sport. I think the hang gliding will make me aware of aerodynamics a lot more. The boat tail is coming together nicely (wood frame, held on similarly to those back bike racks, pictures to come someday soon)
I still own a 1991 Subie Wagon as well and it's great transportation. Especially in the winter snow. Gonna sell it later this year. I think I never got higher than 29 mpg with it which I thought was already good for a 4x4. Curious to see how far you can push it with your planned mods!
