Being a rally guy, drag racing is a different world to me. Just curious on another point...... anyone cut off the alternator (cut the field current) in a drag run to keep the alternator load off the engine for that time, and then turn it back on when the run is done to re-charge? Especially if running an electric pump.... that is just that much more load being run by the engine that could be just sourced from the battery. Or does the higher voltage keep the spark hotter and help?
