RE: Block off plate
It's not really hostile in here, just this topic. It's not just in here too, it's on all boards with all makes. The EGR is a touchy subject no matter where you go.
Just read through the lines and make up your mind on which route you would like to take.
That reminds me...let's keep it civil in here guys, both sides are good arguements, but that's all they are...arguements.

RE: Block off plate
You are horrible at staying on track so I am going to requote your original post. First off, you obviously dont know enough about the internal combustion engine to know that higher combustion temps = more efficient engines. Like I already stated, EGRs are to reduce emissions, they are not put on cars to increase engine efficiency. Whether they have any kind of insignificant effect is NOT the reason they are used on cars. Lower combustion temps = lower NOx, period. That is its only purpose. You also missed the fact that I agreed with you in saying that you should just leave it alone, and dont block it off beacuse it has no noticable benefits and just increases emissions by removing it or blocking it off.
and it is in fact a fact that EGR valves DO increase the efficiency of internal combustion gas engines. Originally (1971, etc), they did not. The EGR couldnt be well controlled, and neither could the fuel/ignition timing. Today, its a totally different story.
They reduce throttling losses greatly. They bring combustion temps down so that you can prevent pinging (and obviously the NOX that occurs over 2500 degrees). they increase fuel efficiency. They allow increased ignition advance due to slower burning of the flame front. Any of those things by themselves are considered "increasing engine efficiency".
I didnt miss the fact that you said leave it alone. Im just pointing out facts about the EGR and silly myths people seem to have about them.
