Hey, someone else from scionlife!

I too am interested in seeing your bellypan. My last tank was 36mpg, and I know there are more gains to be had. I've been contemplating how to build one, and it would be handy to see how someone else did it.

in all honestly, i am thinking that when I finish the belly pan (between the rear bumper and rear tires) i will see a nice gain, because of the air that gets trapped under it at speeds, which really affects the cars COD

You're probably right. That's the part I'm the most concerned with. Even a partial pan only covering that part of the car would probably help a lot.

Nice. I find it amusing that scionlife is about the only make-specific enthusiast community I'm aware of with a contingent that genuinely cares about fuel efficiency. Besides that, it's a pretty helpful and informative forum.

I'm not in any clubs, though, because I live in the middle of nowhere (in the westernmost corner of NY), so I'll be damned if I'm driving 50 or 100 miles for meetups and whatnot. Still, there's at least a half dozen xB1s around here, and a handful of xB2s in my small town.

Come back from the trip, 38.9mpg due to heavy traffic jam when I go. Without the jam, I believe I can achieve 39+mpg with the upper grill blocked. Can I get 40+mpg? Will see on next Friday...

My average isn't so great because I don't always hypermile. I want a a scangauge though. I've gotten over 40 on one tank. My current tank will hopefully be 39 or 40mpg. I have an automatic and use neutral coasting a lot plus some EOC. I try to go under 70 mph on highways and keep the A/C off which is a little uncomfortable sometimes.

Here is my xB spec now:
mpg: 39 ~ 39.5 is achievable consistently
mod: upper grill blocked (both grill block will make the fan on all the time in city), 10W30 motor oil, 44psi tires
technique: I do whatever I can do already, like DWL, coasting in neutral (very hard for xB shape, it slows down too quick), engine off @ traffic lights, time the lights, etc.
Commute condition: 90% highway
Goal: 42mpg, 40+mpg consistently
Restriction: no EOC, which will scare away my carpool passengers
no heavy aero mod, I like original look
Any low cost suggestions? Scangauge is on my wish list. However, $150 is quite a lot. If it helps me having 42mpg consistently, it can break even in 8 months, which is reasonable. But, is it possible? It is another ~10% improvement!!
