I was curious to see this fan kit posted here because one of the things I spent a lot of time working on the cooling for my Blue Beast. Stop and go driving in LA Summer temps with a SC motor was just too much for the Zionsville fan. After a number of tries, the only way we could get close to 3000 CFM was using dual 11" Spal fans.
Take a look at the specs for an Extreme 16" Spal fan -

This monster only does 1950 CFM and draws almost 30 amps. My dual fans draw about 30 amps.
If you look at the gold standard of replacement fans, Ford Taurus fans -
Taurus fan CFM? - Ford Maverick / Mercury Comet Forums - these monsters are 18", so much bigger than this one and push 2500 CFM on low with a draw of 33amps! on high they push only about 4000 CFM.
So I don't want to rain on any parades, but I have a really hard time believing a single 16" fan can move 3600 CFM, and I sure have a problem believing that it can do so with only 11amp draw.
I suspect that you are publishing the m^3/h figure as CFM which is misleading. I would love to know how this fan can do better than the industry leaders like Spal's extreme performance series or the monster Taurus fans.
