I was thinking today about if anyone had any thoughts or has read anything on tuning your intake for fuel economy? By intake, I'm talking about the piping and air filter in front of the throttle body. I think we all know that cold air intakes are good for power, and warm air intakes are good for fuel economy in gasoline engines. I'm not talking about that. I'm talking about designing an intake specifically for fuel economy. I'm talking about pipe diameter and pipe length, possibly a resonance chamber, or a bell-mouth on the inlet. I don't recall seeing any threads on this over the years, so I'm starting one.
