Keeping Your Cool
|
GM Powertrain spends countless hours engineering pulleys to provide the best possible performance within an often very small area. As the drive pulley size is reduced, the rotation speed increases, but if the impeller turns too fast, there may be cooling losses. Coolant flow rate and pressure vary by impeller size as well. Most water pumps on modern GM cars are overdriven about 10 percent to 40 percent above crank speed, while the mechanical power consumed for operation is approximately 12 to 15 hp at 6,000 rpm.
