In the OTL F1 teams racing naturally aspirated engines (mainly variations of the Cosworth DFV) were left behind as turbocharged cars begin dominating at most tracks, the last NA win during the Turbo Era apparently being the 1983 Detroit GP.
It was only from the 1987 F1 season that the naturally aspirated cars received a capacity increase from 3-litre to 3.5-litre, intended as a temporary measure to tide smaller teams over until the turbos were banned at the end of the 1988 F1 season.
What if the ATL naturally aspirated cars instead received an earlier capacity increase to 3.5-litres from the 1984 F1 season?
