Disabling EGR system

I've never argued that... my arguements is based on 2 rediculous statements:

1. More fuel is commanded by the PCM with an EGR (you stated this)- This is not true

2. Detonation is caused by A/F only- not true

3. "Dirty air" from the EGR causes lower combustion temps. Again, not true. The air coming from the exhaut gases is actually rather cool. The elements of the gases, create a chemical reaction (ionic bond) to lower NOX levels, therefore cooling combustion temps. It's not the dirty air doing a thing, it's the certain elements of combustion we strive to get.

Look at a smog pump/A.I.R system.

righto man... like i said back a long time ago they were used to prevent detonation but not anymore. they are pretty much for emissions and gas mileage. "cause detonation because this is not 1967 the world of carburated cars and fuel systems, thus your computer will compensate for more clean air on its own." that comment you left on the other thread was effing hilarious by the way haha

whatever i think we are both a little confused at this point as to what the other one is trying to say... because if i did say that its not how i intended to say it. i dont know.. im going to go driving around and stomp on some little ricers to ease the pain

ima stay out of this one, mainly because i know very little of EGR systems and probably less of the opertating temps/conditions of an engine.

but just to let you know...mark knows what he's talking about, i woudnt take his posts lightly

EDIT: as a side note, i havent heard of anyone ever gaining any power from removing the EGR. all that happens is that the RPMs dont hang as much anymore and you get rid of the bucking that mark was talking about (or so ive heard...i wanna keep my car smog legal so the EGR is staying on mine)

CobraBoy · 03-13-2007

yeah i know he does... but we got so far off topic that it doesnt matter lol. mainly i was just trying to figure out if disabling it would mess with the parameters of the timing and cause engine damage and all that stuff and if it would add power. thats all i was asking

reivaxtorres · 03-13-2007

oh. i would assume so, because the EGR works to prevent N0x (which is one reason its needed out here in cali to help it pass smog). logically speaking, if you remove the thing that will prevent N0x, it means that the car will now create N0x, right? and according to your post earlier, thats at around 1300*C. a car with an EGR, once again according to your post, will run around 600*C. and im sure those extra 700*C will hurt the engine, right?

LOL. a V8 engines runs well over 600*C

The LS2 (current corvette engine) runs well over 1000*C.

and yeah, i figured that. i was just refering to his quote for general information (remind me to mention that next time...) ok, leaving now

you better specify that 1000* is combustion temperature and not water temperature. we wouldnt want anyone to get confused now.

lol this whole thread is so far from anything relevant.. i think i will burn in hell at the mercy of the mustang gods for starting this

if its anything like the combustion temperatures of an engine without EGR, then that would suck.

hahahahahahahahahahahaha

lol so i take it everybodys opinion is basically the engine needs the EGR??? i guess i will trust you guys then and not eff with it haha
