Riddle Me This, Turbophiles
Let's say that in 2010, the IndyCar Series does switch to turbo engines. What engine formula could they use? We know that with out the governance Champ Car gave after Honda and Toyota left, the Ford-Cosworth engines would have been putting out well over 900 horsepower. 900 is not going to cut at oval tracks anymore. And when (God willing) an engine war breaks out, the 2.65 liter engines are not going to stay at 700-750 horsepower.
It seems logical to me that if turbos came back, the engines would have to be downsized. 2-2.3 liters would probably be ideal with turbos, but it seems silly to build a V8 that small. An inline 6 would probably be the better choice. So I have to ask, would you want your series to have a tiny six-cylinder when all other major series run big(ger) V8s?
