I'm working with an old school N/A small block Chevy street/strip car. Currently has a mechanical water pump, flex fan and externally regulated alternator running on a single v-belt. Trying to decide if it is worth the effort and expense to convert to a electric water pump and electric fan and not use the alternator at the track. The old girl does not make a ton of power to begin with so I'm trying to come up with ideas to improve her performance. Anyone have any real world experience with what kind of improvement could be expected making that change?
