Welcome to our Tech Question of the Week Series. Customer Bobby Hackel asks: Do you recommend running with an alternator or without for horsepower gains? Or is the voltage more important through the duration of the race?

To gain new perspective, we reached out to 3 engine builders:

Brad Hibbard from Race1

Don Blackshear from Pace Performance

Steve Hendren from Hendren Racing Engines
