battery charging between rounds?

Al, are you using 12 volt battery(s)? Mine with 2 16 volt batteries has a slightly higher voltage level going down the track as it did with 12 volts and the alternator charging. My FAST ECU & MSD box loves volts. Runs 15.0 to 15.3 on the data logger, depending on if I let the fans & water pump run in the staging lanes. On 12 volts it was a tick faster with the alternator charging. Did slow it down some with pulleys. Had to have it aligned well to keep belts on at 8500.
