Neff: With the throttle body being tied in to the EFI system, is it possible to use EFI settings to reduce power or does that open a big can of worms if you monkey with those settings?
Yates: At the end of the day, the way you control power is through reducing airflow to the engine. It is an air pump and the more air you give it, the more power you can make with it. If you reduce the airflow, just like we do at Daytona and Talladega through a restrictor plate, that is a way to get there. Somewhat controversial but, through the years, like when Bobby Allison went into the fence here in 1987, that was with an 830 carburetor. The first thing they did was make them go to a 390 carburetor at plate tracks, so it isn’t unprecedented. That reduced the air flow and that was the first step in going to the restrictor plates. It isn’t really that big of a deal; it is just a matter of what size throttle body do you want to start with?
