I saw that they sell a kit to block off the egr valve in my dodge neon. Since this was on a performance site what will this do? Will blocking off the valve give me more horsepower? Should I do it or not? Thanks
i own a repair shop,and it wont give you much more horse power if any,all it does is stop the egr valve from working ,the kit allows you to remove the valve and put a block off plate on it,some say it helps a little i haven't noticed much of a difference in the vehicles that have them on,they just don't recirculate the exhaust gases like they should,which causes any car to fail an emissions test,that's about it,good luck,i hope this help,s.
The EGR valve only opens when there is hard excelleration.That can cut down very slightly on your power.Your fuel system is compensated for the slightly lean affect it gives when open.If it's working correctly, you will gain very little performance by blocking it. But just blocking it off, will help a little, you probubly you won't notice though.
If your vehicle has to pass an emission test in the state where you live, it will fail due to high NOX emissions. Aside from that, it's illegal in all 50 states. Generally speaking, blocking off the EGR will result in poorer fuel economy, possible engine detonation or pinging and higher combustion temperatures.
