depends on thermostat..but remember the supercharger requires work from the motor to turn it and causes a parasitic drag slight though it may be ....it can cause temp rise but I'd make sure you have an adequate radiator for the task on hand....I have a 347 and a 180 stat and 2 core aluminum radiator and temp is right at 180 all the time
