Quote: Others prevent max power from being produced like EGR valves
I call BS on that one, an EGR cools cylinder temp therefore making an engine run more cleaner and more efficient. Producing more power. As far as a charcoal cannister and the smog pump, they pull an engine down. Ditch them if ya can.
EGR cools down the combustion chamber temps, thereby lowering nox output. This has the same effect as lowering the compression ratio, ie cooler combustion chamber temps. Cooler combustion chamber temps = less power/efficiency, plain and simple.
