How close, is to close for rad fans to water pump pulley space

Well,... That didn't take long. I bought it from Mancini Racing. You are right. The description now says "Rated up to 10,000 RPM". I don't remember where I got the 8000 RPM rating off the top of my head. Maybe it was 10,000 RPM all along and I was just remembering wrong, or maybe I was thinking of another model. Mine is the 18" Heavy Duty Flex Fan, Part# 17018

I have used that fan on several cars over the years. Works great. Make sure you don't buy the reverse flow fan like my neighbor did. I made a shroud to fit the aftermarket radiator, since the stock shroud wouldn't work. Shrouds not only help cooling at low speeds, they are a safety device. All my cars have them. Get the biggest fan that will fit the area without hitting anything.
