The derale/flex-a-lite shrouded fans are great. I have a ~3k cfm one on the v8 drift car, it almost never boils over. Itíll usually sit at 210-220 while it bounces off the rev limiter for 6 hours straight.

If you look at all the race cars that use Spal fans, the fan is usually 6+ inches from the core and with a fully sealed shroud. Just mounting one to the back of the rad doesnít do much.
