Benefits of ant EGR delete ?

does anyone know any benefit's that deleting the egr valve would give you ?

None other than if you had an IC it would prevent your core fins from getting blocked. I have a plate for my EGR so in a matter of minutes I can block it right at the valve itself. When I was IC'd mine was blocked off. After going back to non-intercooling, I've swapped it in and out a few times looking for any benefit one way or another. I couldn't find any, to tell the truth.

The one thing I've noticed is that the s/c inlet gets a little deposit on it, However would it not be better to go into the intake and be burnt versus, potentially clogging the cat? I can't accurately guess as to the answer, but my feeling is yes.

You live near me you'll want that on your car.
 
I have found that my car is easier to tune, and gives a much tighter tune. Thus making my car run a bit smoother. And the tighter tune increased my mileage about 1 mpg.

EGR delete is best suited for IC cars. And a tuner is a must to retune the car correctly after it is removed, IMO anyway.
 
Cleaner intake runners overall, I think its worth removing IMO. If anything, DEFINATLY remove it if your ICed. It costs hardly nothing to pull off...

I assume he lives in STL and as a result will likely find it helpful to at least make it look like it's functional.

As far as intake runners, wouldn't the little amount of coating from the EGR smooth the rough texture and be the equivalent of low budget polishing?:th_laugh-lol2:

Seriously though, I would rather have less clean intake runners than a clogged cat.

How many clogged cat's have you seen from EGR deletes?

It's only a thought in print:rolleyes:. When I took my blower apart last week I noticed the slight oily film around the EGR port. It occured to me that if I still had my EGR blocked where would that stuff go?
 
yea i am from St. Louis i'm not sure if i am going to go with a EGR delete especially since i just got robbed for some money today the problem that everyone told me was my CPS ened up being my Fuel Pump, I was wondering why i was getting 17mpg on the highway, talk about a gas hog so that sucked about $900 bucks outta my bank to have my trusted shop do it for me because i didn't have the time to do it. Does $900 sound like a rip for a Fuel Pump + Relay replacement ?
 
After so research the pump runs at about $334 and the relay runs at about $21 here are the item numbers just incase anybody needs them at some point and time:
ACDELCO Fuel Pump item number #MU227
ACDELCO Fuel Pump Relay item number #15-50448
 
Well they don't have to drop the tank to put it in so I don't think the labor time would be that long. However we live in an area with the highest auto repair rates. Dealer 3 miles from my house charges $135 an hour. At those rates it doesn't take long for the money to get large on you.:(

Oh and they will have to mark up the parts too.

Looks like PRJ charges $210 for a Racetronix pump with wiring harness. This is supposed to be one of the best fuel pumps.
 


well they do know that i do have some mods done which i wouldn't complain if they did put something better in there but then i think to myslef what are the chances that they would do that for me ?
 
Who runs a cat? I lost mine a long time ago.

And deleting the EGR ain't going to kill the CAT (if you have one), thats a myth.
 
Also it cleans up te engine bay a bit I put a plug in the LIM and the rear mnfld I cut off the tube on # 6 weldedup the primary then had it jet hot coated.

How do you know this? No really? If it's a myth it's one I've never heard it before. I only mentioned it because it seems to makes sense that if the residue does make it to the intake then it has to go somewhere. Doesn't it?

Oh and I run a cat because you will not pass inspection here without one.

Running without an EGR isn't going to kill your cat. Many cars run without an EGR and have a cat, straight from the factory. Also, your EGR isn't recirculating exhaust gases all the time. Only part of the time. And at WOT, it is disabled. When do you think you make the most potent exhaust gases, when you are running rich. When do you run rich? WOT. So when you are running the richest, making exhaust gases with the most deposits in it, the EGR is disabled. So if the EGR was needed to prevent the cat from clogging, wouldn't the be operative at WOT?

Also, the CAT burns hot enough most of the time to burn out these deposits anyway. Running without and EGR isn't any harm to your cat, bottom line.

Do we not know that running too rich shortens the life of the cat?:th_scratchhead:

I've heard of that....and certain fuel additives etc etc can destroy a converter....I've just never heard of idling doing this. Not saying it won't, I"m just curious.
