Heat and air conditioning can make the difference between a comfortable drive or a brutal one. A blower motor resistor is an adjustable resistor. The blower is a positive displacement air pump. The blower is used for moving air from either an outside source--referred to as vented air--or from cabin air past the heater core or air conditioning evaporator. Boost is the amount of air pressure created by the supercharger and is mainly the function of three factors: engine displacement, blower displacement, and blower drive speed. Centrifugal superchargers rely on an internal impeller to step up boost. Under the glove compartment door there is a soft panel that can be moved out of the way, exposing a brown wire which is the ground for the blower. On the low setting, 12 volts will go into the resistor and only 4 volts will come out to the blower. This site uses Akismet to reduce spam. The majority of the time, a failure will be found in the blower motor resistor or the motor. However, if your vehicle already produces good low-end power and torque, a centrifugal blower is the best choice for maximizing high-rpm power. Check the blower motor at its two-wire connector for power. In others it might be located inside the dash (e;g Mazda 5) which makes replacement difficult. How much horse power gainage does a supercharger, when installed.? The classic blower motor resistor is a block with various resistors inside it that will switch power to the blower through different resistors based on where the blower switch … DC car blower motor drawing too many amps, or what?! The speed at which the supercharger fills the cylinders depends on how quickly it is driven by a pulley and drive belt. However, Roots-type blowers produce a flatter torque curve with linear power across the rpm range, making it the ideal choice for adding throttle response and streetable low-end power. It still operates the same and is located in the same location. Using a Leaf Blower to Dry Your Car. The speed at which the supercharger fills the cylinders depends on how quickly it is driven by a pulley and drive belt. Thanks. The main drawback to Roots-style superchargers is the consistency of the air charge. Nothing could be further from the truth on both counts. By making some engine modifications you can assure yourself that your boost level will land on the high end of this scale. In part two of our Blower Basics series, we’ll provide some valuable information on how your static compression ratio relates to safe boost levels. This allows a smaller displacement engine produce similar horsepower and torque to a naturally-aspirated larger displacement engine. Some blower motors are easy to access, and others are buried under the dash. //
