Yes they do work. I run a Flex-lite fan(Plastic) That has a 1/4 Of it cut off and It still Out draws The Stock Fan By a Long shot. And I have been running this same fan for Over 20 yrs. I can take a shop Rag Folded in half and The Air Draw Will Keep it Pined to the Grill. I have ran The Metal flex Fan (Good?????? to 8000 rpms) and Broke/Cracked two After that i went to the Flex-lite fan and Never Looked.
I have read test that those Flex a light plastic fans rob the most HP like 20 HP or more.
They really beat the air into submission & can't keep on track.
Supposedly the best fan is a fixed clutch type fan for less HP loss.
The HD clutches with the little spring on the front of the clutch are the good ones.
With that type of clutch fan,,, it was within 2 HP of running no fan at all,,, IIRC???
A stock 4 blade steel fixed fan will blow a lot of air,but those to, take HP from your engine.
