okay im debating on what to use here. ive always been an electric fan guy. have never used a flex fan mainly cuz ive been working on mustangs for the last 4 yrs and there is not to much room in that engine bay. but now i got a g body with a huge engine bay and space is not an issue here. it had one of those ss blade supposedly high performance one but i threw it away cuz it a few blades were kinked. and i like how the flex fan runs off the engine so it could pull alot more air i assume. so which is better the metal one or plastic? and i always know there is a chance it can break and cause alot of damage but im not to worried about that, they have been using them for years and still do so they are doing somethin right to keep using them. and i believe in murpheys law, if anything can go wrong it will. so who is to say my balancer wont fly off and do the same damage. plus i work at a shop and if i buy a flex fan from auto parts store and it flys off and destroys my radiator and hood and whatever else i can make a claim on it. but what are u guys running? what works better for mainly street use, im in tx and it gets real hot in tx traffic. does plastic pull less air than the metal one? i have a friend with a bu he runs the plastic fan with a 15" electric cuz his car heats in traffic. not to sure if its cuz the fan is to small or cuz the are just made for racin. but he says on the highway its good just in traffic it heats. and he doesnt use a fan shroud so im sure that has a lil sumthin to do with it..
