Not sure if this went out so I'll post again (Digest mode).

This is correct, 2800 CFM. Some members are using Hayden fans
rated at around 1900 CFM, so you know the Flex-a-lite duals
(2500CFM) or the Black Magic has enough cooling power.
IMPORTANT!! I've measured the distance between radiator and
fan stud (98 Dak), there is only a little over 4 1/2 inches
clearence, so the Black Magic fan will be very close at 4 1/4".
I mounted the dual 220 (2 1/2" clearence) and no problems. The
black magic may be an easier install IF clearence is ok.
