I'm thinking about going to an electric fan and need to know if a 16" puller fan located inside my existing fan shroud flowing 2500 cfm will be enough air flow to sufficiently cool my 470 570 HP engine ? Or do I need a dual fan system flowing more ? Its in my 85 Regal and I'm using an American Eagle aluminum radiator dual core 2.5" in width. Thanks ahead of time for any info.

you will be close with what you have ,I have a four core rad with a dual 13 set-up and that keeps it under 190 .I have about the same hp
I have a dual core (1-1/4" cores) aluminum rad and a Ford Taurus/Lincoln Mark viii 2-speed electric fan and it keeps my 462 at 185-190 even on the hot Ohio summer days (95 is about the hottest I drive it in) without the high speed. I've not even wired in the high speed yet, but just with low speed I've never cleared 190 (that's running a 180 thermostat) . I swear by it, bang for the buck is unbeatable. I'm running no shroud, just the fan as a puller as it comes.
Thanks for the info guys I like anything that will keep me under 190. I'm running at 190 up to 200 when I idle for a long time but 180 running down the road using a 16" declutching fan. I don't like that extra heat. I need to change the fan system for sure. Roger On The 8th Day God Created Buick
