In the past I researched the lectric fan thing pretty hard. I had to, because most of the manufacturers sell their fan according to horsepower and I was building a motor that was going to be higher than what they sold. I looked at all of the larger manufacturers and finally I talked to the guys at "Be Cool" and they convinced me that the "SPAL" fans were the best to deal with. It all stems from how the manufacuteres measure the airflow across the radiator when the fan runs. There is a static flow (air across the radiator and the fan only) and there is a dynamic flow (air across the radiator and fan with the backpressure of what an engine bay would have). SPAL measures their fans in the dynamic format, where most of the others use the static measurement, I even asked about this to the distrutors and they agreed, thus the limits on horsepower. I chose the SPAL 11" dual fans for my 84 GMC with the 383 stroker in it and I am not sorry. I am pushing some more Hp than compared to a factory truck, though.

I am here to tell you that when making the purchase, think out the process and don't just stick anything in there that might do the job. If it doesn't work the first time then you have to buy another set and that is where the cost starts to add up.
