The "usual" drive ratio of a SBC mechanical water pump is between 1:1 and 1.3:1, over driven. | The "usual" drive ratio of a SBC mechanical water pump is between 1:1 and 1.3:1, over driven. | ||
| − | + | The location of the pump is of great importance. Some vehicles have been built with high mounted water pumps which have been a disaster. In the case of a vehicle which has its engine mounted north-south, the water pump will often become the highest component in the cooling circuit when the vehicle is ascending a steep hill. Engine designers ought to study Steam Trapping and Air Venting as it is a very important topic even for things that do not run on steam. | |
With a transverse engined vehicle it is possible to have the water pump behind the engine block. With this arrangement steep hills will not starve the pump of water. AVOID any car that relies on venting screws in its cooling system. | With a transverse engined vehicle it is possible to have the water pump behind the engine block.
