Redundancy and Overkill time, (best reasonably priced thermostatic cooling fan)

mopowers said
You need to better explain what's going on. You have two pusher fans, but you want your buddy to build a shroud? Where would the shroud go?? On front for the pusher fans, or on the back for an additional mechanical fan?

If the cooling system is functioning properly, all you should need is a properly sized puller fan. If you need pushers, something is wrong - especially at <400 hp.

i Want to add a manual thermistatic fan with a shroud, to accompany the 2 electric pushers, hi vol water pump, and a/c pump pulley for more rpm's, already have the biggest rad i could fit. I have an ac condensor almost as big as the rad, because i have a loose converter which I will be driving on the street. I want to build the system ONCE, tune it and forget it !
