My 2006 F 150 which the Aerolid was on has a greater frontal area than your truck ("Spirit of Ecomodder").
Due to the small cross section of A2 and the large frontal area of my truck, I feel the delta Cd number may even be better than calibrated. I wish Ford would have shared the delta Cd with me back in August of 2007 when they tested my lid in their wind tunnel in Michigan. The cross section was cavernous!
Hopefully John will get some good mpg numbers with the Aerolid alone and with the combination of the large boat tail on his new F 150. Also, you did one fine job in crafting the "Spirit of Ecomodder". You are as good a craftsman/Engineer as anyone I know.

Hey Brett,thanks for the insight.Perhaps one day Ford will find it in the heart to declassify the data.We sure could benefit from it.
Regardless of the numbers,the smoke flow reveals an extremely healthy boundary layer over the Aerolid,and your eye-balling has produced a high bar in cap design.The tail too!
November won't get here soon enough! I'm like a kid waiting on Christmas!
Appreciate your comments on the T-100's build.I do aspire to do some OEM-appearing mods one day.Just like yours!
We're gonna get hit tonight with the storm.Keep your umbrella handy.
