What is needed to block off EGR?

TrippiGT · Mar 14, 2008

I put on some MAC LT's last week and when I was trying to get the EGR tube off the headers, I twisted the tube. This put a nice little hole in my egr tube. I tried to used an exhaust patch on it but it didn't work. I have a plug for the header and my friend is making me a plate for the throttle body. What vacuum hoses do I need to block off. And do I need a tuner to turn off the egr from the computer? It's on a 99 GT. I know alot of people have done this but I couldn't find anything that answered my questions. Any input would be helpful.

Randy Stinchcomb at Liberty Ford sells a kit that deletes the egr. Just look up the number online. There was a thread not long ago about the egr delete you could find in a search. The egr gives better gas mileage and allows more part throttle timing, which means you have more power at part throttle. There are no power gains other than less heat in the intake and a cleaner engine bay, and yes it will need to be tuned for the egr delete.

so by deleting the egr,it would have more power and or run better???

no gains whatsoever, just fail emissions testing. people dont like the look of the EGR valve on the motor so it cleans up the engine bay a little bit.

My mustang came without an egr valve when I got it and I wondered the same thing.

It's good to read an intelligent post once in a while... Good job!

Too add to what you said above:

At idle and WOT (80% and over in the TPS range), the EGR is not in play.

EGR's major function was to reduce NOX emissions by introducing an inert gas into the combustion chamber which in turn, keeps com temps below the 2500 threshold.

The only reason I want to delete it is because of the hole in the egr tube. I'm pretty sure having an exhaust leak is hurting me slightly. Instead of trying to replace or patch the tube I decided to delete it. I already have a plug for the headers and a plate, so I figure it would be cheaper and easier to do that. And it would clean up my engine bay a little.

Keep in mind that you MPG is going to take a hit, and you do need to be able to turn it off in the computer, so figure that into the cost. I've got mine deleted because stock tube won't work with my supercharger. If I can find a way to replace it I'm going to put mine back on.

Get yourself a new factory ford tube or have it brazed. I know with stainless it is recommended that you use silver... with the cost of precious metals, you're probably better off buying a new tube.

I ended up fabbing my own delete plate, and taking a cutting wheel to the tube on the header and shoving a bunch of of quick steel in there. Since its still a few inches away from the exhaust flow, it doesn't get hot enough to melt the epoxy. The stuff is good to like 500F. No leaks thus far.
