Since pretty much the beginning of internal combustion engines. As long as it is at given power.
No. On a modern engine, the ECU adjusts the fuel to the amount of oxygen present. So it would increase performance. Hence the need to reduce throttle if performance is to be the same.
Head losses due to the basic geometry, i.e. at constant throttle.
Head loss is the official word for the effect of flow restrictions. (Which are most of the time differences in pressure, rather than velocity, as you seemed to think in an earlier post.)
Please read again all my original posts. The performance was to be held
*constant*. If you want to drive a given speed, performance (or to be precise, engine horsepower output) is given, not something to be optimized. Fuel consumption is then to be optimized, and that is a very different matter.In your original post you stated,
"Logic tells me that the intake would increase the fuel economy even more." and I asked "What logic?"
If you check the subthread you are responding to, you will find that this is the issue under discussion, not maximum horsepower that the engine can produce.
I did not make any personal remarks at your address. Why do you do it at mine?
