My calculations are that a new bike fully aero will yield a time savings of 2.5 minutes!
My running pace in 2006 was 6:38 min/mi. If I run an average pace of 6:00, I will take 3:44 off my time.
My average Eppies finish time over the last 3 tries was 1:52:30. So if I take this 6.2 minutes off of my time, I will finish in 1:46:20. Wowsers, that's fast.
