We all know that fuel is made up of gasoline and air. More air + more gasoline = more power. However, in naturally aspirated form, our engines are only capable of ingesting a very specific volume of air. How does changing the stock plenum and TB add any more volume of air into engine? It’s not like a blower where air is being compressed into the engine with pressure.
It just doesn’t make any sense to me. Keep in mind that I am not disputing anybody’s claimed hp. gains, I just don’t understand what causes the gains over the stock plenum. How does more air end up inside the engine from an aftermarket plenum?
