Hey - Young vanner here

Ah, thanks to Bearleener's "back of the envelope" calculations I can see we're talking a bit more than 10% of 20% here, but not by much. The "wind tunnel" thread talks about how, at a constant 60 mph, a reduction in Cd of .01 is the equivalent of removing 220 pounds from the car. I would expect that figure to exceed 300 pounds at a constant 70 mph, and nothing I am doing to the interior is in that magnitude.

Alright, no one closed my thread so let's necro it. Thank you, incidentally, to all the amazing users on here: the time and effort the users put into this site have always seriously impressed me.

I still have the van (not to mention my login info). I can't bring myself to sell it - too much faulty "customization" anyway (did you know splicing starter wires together with electrical tape lasts you about a year?). Here's the short story:

High-top conversion van (7'7"). 305 V8 TBI with 3-speed automatic. 9/13 (EPA is 13/15), my record for a tank was 15.6 (all night through Missouri). Here's an emissions report (lol):

HC GPM (gallons per minute?) = 5.78, Limit = 3.5 (Unburned fuel)
CO GPM = 71.5, Limit = 30 (Air/fuel mixture too rich)
CO2 GPM = 527, Limit = None
NOx GPM = 1.4, Limit = 5.5 (High temperatures)

A replacement van on my budget is 18mpg, so 20 with my driving style. Surely for that kind of money I can do better. Within the next 6 months I'll be putting together a budget (~$5000) and strategy for tripling my gas mileage while still using this thing to move.
