My motor has a stock 190* thermostat in it but if the weather temperature outside gets above 80* the motor over heats by 10*-15* at idle and stop and go driving (I have no problems on the high way). So my question is: how many people run auxillary fans and how big of one should I run? I bought a 14" fan that flows 1250 cfm with only 11 amps draw to run when I'm putting around. I was debating on running 2 of those fans and ditch the stock clutch fan. But I was wondering if 2500 cfms ( about 2100 cfms actually through the radiator) would be enough to cool the motor on it's own. Plus I might be able to pick up a few extra ponies. It's fixin to get warmer here in a few days so I'd lilke to get everything on there hopefully next weekend. Also, do I need my stock fan shroud? It's cracked and broke where the mounting bolts go and sort of just floating in there. I had a buddy that had that happen on a mustang and it bent one of his fan blades and shredding his radiator. So can I go without it? Especially if I ran dual auxillary fans and the stock clutch fan. Any thoughts or comments would be greatly appreciated.
