But to race I had to follow instructions.

That really makes no sense at all, considering that you are allowed to run an electric water pump, that has no provisions for a belt driven fan. I never ran a belt driven fan on my Mustang, even with the stock water pump and a Moroso electric belt drive. Considering how slow the water pump spins with such a drive, and 5.0 Mustangs used a reverse rotation fan, doubt it would do anything, anyhow. Larry, was this a NHRA Tech official?
