It will get you a check engine light, higher emissions, failure of any emission test inspection and a zero performance improvment. In other words, a waste of time and effort

That's what I was thinking, but just wanted to make sure...I love tinkering though, so more power to ya!

zero how do you know? it blows hot exhaust air into the manifold this would make the intake charge a lot cooler and you can disable the light with the diablo also the fact that the tube looks like it protrudes pretty far into the air flow with that removed it would even out the air flow

Darnice is correct (before going further i'm driveability {engine performance} and electrically certified with ford motor company and dcx). The egr is only flowing at one time and one time only. . . at 0% throttle. If there is even so much as 5% throttle egr system is deactive. It is for emissions and what else? anyone? Ding ding ding It also helps control spark knock. With plugs on one side of the head and not perfectally centered the flame front in the combustion chamber has to move. Basically once ignited the flame travels during the combustion through out the chamber it doesnt just ignite in the center.
Darnice was exactly right in what he said. Egr systems have always worked this way whether electric or vacuum. Throttle = no egr. The only benefit to removing it. . . weight. Or you could eat one less happy meal and accomplish the same thing

im sure he is making a plate for that as well.

so basically at idle is when it is on to move the flame where it needs to be? Thanks for your the reply makes sense. Now what if you cut the tube down to open up the intake flow in the throttle body. I know this is a free mod for the ls1 guys wonder if it would work. I would think the egr would still work the same right?

No it's also used on deceleration. When your off the throttle and cruising down hill for instance. The design of the tube could be for a reason. Either a/ it protrudes so far in as to aim the hotter air to a different portion of the manifold or b/ its the same tube for 4 or 5 other models and chrysler just reused it on chargers to save costs. there are a lot of stupid looking things on cars that some of us are like hmmmm what the hell did they do that for. I can tell you from going through tons of training with engineers and having engineers for friends they all have a reason and a purpose, other than the parts cost reasons. Some times they do just recycle parts for cost effictiveness.
For example89- 91 escorts came out with metal bumpers on manuals and fiberglass on auto's. Everyone thought this was stupid as you normally get the cheaper stuff on a 5 speed. Several engineers taught us it was because the idle vibration of the 1.9 was so bad that if the car had a metal bumper and a torque converter it sent so many vibrations into the cab that the driver nearly got shaken out of the car. Putting on the cheap fiberglass bumper on the a/t's dampened the vibration and hid it so well that on the a/t cars the driver only halfway shook out of the car. Ask anyone with a 90's or early 00's escort about how it shakes at idle.

Another instance. Anyone here own a 00 + neon???? If you've ever looked at your top motor mount it has a 2 inch wide piece of aluminum screwed to it. Looks stupid and i've been a neon builder and racer for years before an engineer finally told me what this little piece of aluminum was screwed to my motor mount. It was an engine scraper. Designed to , in a wreck, push the motor away from whatever it was hitting. I saw videos of this little 2 inch piece of aluminum actually doing its job. If the impact was just right, hahahaha, the entire engine tranny assembly would push to the side and basically do a 90 degree turn and end up on the ground in one piece but still in tact and useful. Hard to explain and show without the video. Damn

I've heard of this before, I didn't realize the neon had it. I guess next time get a chance to look under my sisters car, I'll take a look at that.

Wouldn't disabling EGR with the Diablo Predator be essentially the same as plugging this wire? As for performance gains, i did notice a substantial improvement in acceleration since installing this. My idle improved and acclerating off the line in everyday driving is much much smoother.

Yes using the Diablo to turn off the EGR would be the same, I was just looking at a way to remove the EGR completely since mine is already turned off. The intake side it plugged also - a plate will not work on the intake.

Had some time, figure I would make some plates and see what the reaction was on the board.

Sorry to correct you. But EGR is used during cruising conditions, not idle. I believe wikipedia provides a far better description that I can provide.

http://en.wikipedia.org/wiki/EGR

Removing the EGR valve is considered tampering with the emission controls. So it is illegal. But there is some benefit to those who do. The EGR valve contributes to all the soot build up on the throttle plate and intake valve. Stopping the soot build up means you won't need the throttle plate cleaned and fuel injector cleaner when the engine reaches high mileage. But your engine will run hotter during lean conditions (ie cruising). And that is bad.

The scrapper is on the top motor mount by the cam pulley.


The egr does run on idle on some vehicles. Wikipedia is not factual information in 100% of the circumstances. Wikipedia can be altered and changed by anyone who wants to and that has been posted on this forum a million times so people quoting wikipedia as fact is not a good thing. The charger does use about 25% egr at idle if no accesories (a/c, defrost) are being used. Plug in your diablo and check for youself.ALthough a star scan is far more accurate and reliable. However, not all cars are that way.


You've got people on here contridicting themselves. One says egr never activates on idle and the next says idle is a million times better with no egr so to anyone who cares, you'll have to decide for yourself.
