1 guy, 1/4 mile at a time. The typical mine never broke story. No body will admit if theirs did. Not a good story..
How many cars have flex fans, how many cars don't. About a million to one ratio.
I had an aluminum flex fan on 2 cars for years until one broke. I didn't get hurt but my radiator sure did and I wasn't turning 2500 rpm.
No more for me, my mom didn't raise no fool.
Yep, do not run a flex fan, eventually they will fail and maim bodies and/or damage vehicles. Happened to me back in the 80’s on a SBC, that’s how I know, lucky it was just my hood that got damaged.
