finally tested a missing link that had been bothering me. i couldnt find where someone testing smooth hubcaps compared them to regular hubcaps, only to no hubcaps at all. tested at 65mph using SG2. 3.6mile test section each way. run 1 and possibly even #2 might need to be thrown out, coolant was up to regulating temps for a few miles before start of test, but im guessing not everything was sufficiently warmed up.
#1 taped south: 34.1 north: 39.7
#2 taped south: 34.1 north: 40.9
#3 none south: 34.4 north: 39.8
#4 none south: 34.4 north: 39.8
#5 taped south: 35.6 north: 40.8
#6 none south: 35.4 north: 39.8
#7 taped south: 35.6 north: 40.3
#8 none south: 35.6 north: 39.0
#9 standard south: 35.9 north: 40.3
#10 none south: 35.7 north: 39.7
#11 standard south: 36.3 north: 40.2
wind didnt seem to be a factor, but i recorded it anyway, readings from weatherbug. the road tested on runs dead straight, from nnw to sse

havent teased out results yet, and figured you guys like raw data better anyhow
