  • Radiators: Aluminum vs. Brass

    There is an age-old debate about which material is better to make radiators from:  brass or aluminum. Most people focus on the radiator core design when choosing a radiator - how many tubes, tube size, how many fins per square inch, etc. - but the core is not the only part of the radiator that can cool. The sidetanks hold more of the cooling fluid than the core!

    Just about every high-performance vehicle you see in car magazines has an aluminum radiator. So you might assume that aluminum has the best cooling properties. That actually isn't true, and we'd like to share some facts and test data that compare aluminum to brass, and even to composite radiator sidetanks. Continue reading

  • Which is Better - an Electric or Belt-driven Fan?

    This debate is as old as the electric fan itself. We manufacture both, so we're pretty unbiased on this topic. In fact, we created the first high-performance belt-driven fan in 1962, and we were the first to introduce an aftermarket electric fan to the U.S. in 1978.

    We'll jump right into the heart of the matter: An electric fan is the better performance solution, freeing up maximum horsepower and mpg. But it's not always the better cooling solution. The full answer to this question is that both electric and belt-driven fans have their place. Which one is better depends largely on the specific application. Continue reading

  • The Truth About Airflow and Amperage

    When you're in the cooling-fan business for 49 years, you hear a lot of ideas and theories on what makes one fan better than another. You also run across some pretty interesting ways that people use to determine what fan they need to best fit their application.

    One of the assumptions we frequently hear is that the fans that draw the most amperage are better. We'd like to set the record straight with some facts and definitions, as well as some actual product-testing results.

    There are a lot of factors that determine the efficiency of an electric fan; the amount of amperage the motor requires is only one of these factors. Continue reading
