roger i've got a couple spal's here. various sizes. are you looking in from or behind radiator application? how much depth have you got for it to fit if behind?
i have slim line spal and a standard. think they are 14 or 16"?
i also have a NIB rapid cool i think it is.
Very few fan makers actually make good fans. Most all the numbers are complete BS as they are rated free air, that is no load from something such as a radiator in front of them. Spal is one of the few aftermarket compaanys that makes a fan that can draw air under a load. Another one is http://www.emp-corp.com/products/advanced/components/F11ElectricFan/ but the price is a little high. I do like that they are rated to be submerged.
Great link!..now THAT looks like a real fan.
How thick is the Taurus fan set up?
