Simple. What would entail completely getting rid of that damned EGR, and setting up a system that won't throw a code?

Reprogramming the chip, or what?

Why? Well, the Sunshine State could care less about emissions, and I don't want that crap exhaust coming back into a newly cleaned intake, yanno?

 

well, you'll need to block off the EGR passages
and have a custom PROM written to delete the EGR

i'd keep the EGR, its not costing you any power
PLUS, your engine was design to use it
it keeps your NOx gasses to a minimum and helps provide the cylinders from overheating, thus preventing pinging, knocking, and desieling

in short- its not worth the trouble and its probably better to have it

 

Where ya live in FL, Doward? I'm in Brevard county..and yeah, Florida doesn't give a rat's *** about emissions...I've got a friend running side exhaust with glasspacks...no cat, no smog pump...nothing..cops don't even look twice. Got an open-headers 383 across the street...it's getting exhaust before it hits the street but I heard them fire it up for the first time with the new carb on it...guy at the END of the street built and tuned the carb and helped a LOT on the engine....that thing is a BEAST. Was shaking the ground beneath my feet. But besides that....EGR's GOTTA be a pain in the butt to do..it's kind of vital equipment. Not to mention it's got like 4 or 5 different operating modes, all of which operate differently...whewee.

 

Get the Feb 2003 issue of CORVETTE FEVER at your newsstand.
22 detailed pictures how to solve any EGR problem you have. Yes, it all correlates to our V-6 systems, also.
AND the article shows how to make a simple diagnostic tool to test while ya drive.
It's really easier to solve the EGR then work around.

 

I 2nd the motion .

 

Been down that road, made a plate to cover to egr, and all kind of crap. car idled better but thats about it.

its better off hooked up,

but but the PVC system is just as dirty, and it only needs to vent, that little hose that plugs in by the throtle body, I put a 5 buck fancy blue andioze filter on there.

 

psh. EGR, smee-GR. That crap is coming off. The PCV is also gonna be routed through a double filtration system. I mean, I need all the available intake space for AIR molecules. You know, O2 and all that to make some POWER.

I know, driveability wise, no diff. PITA to remove? Not when the engine is already out - and talk about cleaner compartment. Just looks like I need to tell teh computer to not turn on the EGR till 255 degrees, and it'll never know the difference

 

Gumby...you don't throw a code or anything or run odd with just a breather over the PCV thing? I'd rather get that out of the way..it's just a pain in the *** to work with when you're making a custom intake arm, etc. So you put a breather on the passenger side PCV connection...and was it one of the Autozone ***** breathers?...did you do anything special to the driver's side PCV setup, or just leave it?

 

nope, no codes, its just the PVC, only problem with that is on carbs, gotta make sure your not making a vacuum leak. sometimes the pvc circut runs throuhg it , but on ours, or mine, it rounts from one side of the engine to the other and right up into the intake. If I had two of them filter I would do each side.

just a crank case vent.



though on some things, sand drags, mud drags, they run sealed PVC through big stainless lines and they hook into the headers about 4 inches from the end. keeps the same pressure above and below but I guess its tricky and not needed.

------------------

back on the EGR, could you just let that vent???? so it still thinks it working but it dont. put a filter on it. cotton so it wont melt

 

Yeah...I didn't figure it would cause any problems...I've run with the PCV tube just hanging away from the intake tube before..no problems. Lol.. I assume you just twist and pry and the rubber grommet will come out on the passenger side..is the driver side just as easy or is there anything extra I need to know? I've got some spare money and am trying to beautify the engine bay...just found out my sister got me a brand new coolant overflow tank for Christmas (Yeah, I peeked..) and I got some bright blue silicone vacuum hose yesterday, and some blue spark plug wire separators...onto the breathers!

 

seams like every auto parts store has that new little **** section, of filters, coffe can size tail pipes, clear tail lights and hokey stickers. but I they they got some nice little filters.

I got scamed on mine, the pic was 50 times larger than actual size. I thought I found a steal [$5]. Till this silver dollar size filter showed up at my door.

 

thats fine in theory, but remember, more air+less fuel=lean
lean=pinging+knocking
EGR is there for a reason, it'd be wiser to leave it, unless you can have a custom PROM programmed a little bit richer at higher RPM's (when the EGR would be open)

 

The EGR is there strickly for smog reasons. By having it there only allows hot exhaust gases to re-enter the combustion chambers lowering the density of your fuel charge. The cooler your fuel, the more denseof a charge it is, the more power you have. Remove it and bump your fuel pressure a few #'s.

I just unhook my vacuum hose and plug it, then its still there to rehook for smog checks.

 

pic.

Think I should put a washer on that alt. bolt??? naaa

 

Ah... funny, but no. EGR is not open at idle, or WOT, IIRC.

Even if the fuel were an issure, would I go through the trouble of killing it via the prom, without adjusting my fuel tables? Hell, or the spark tables for crying out loud!

Also, the emissions is a moot point. We in Florida bask in the warmth of our power hungry engines...

 

That's the one truly great thing about Florida...only thing that makes me want to stay in this state!

 

i never said it was, now did i?

 

I'm not gonna be runnin a EGR valve. I am in FL also. Gettin ready to put headers on mine and i'm not gunna go cuttin/drilling holes in the new headers just so i can put the EGR back on! Gonna burn a chip so I can run without it.

I've seen several WOMEN from Florida that could convince me alot better than a noisy smelly engine!
I especially know a BEAUTIFUL former girlfriend (who just moved to a beach front cottage) that would.........

Where does Florida excess emissions move to?
CUBA?

 

Funny you say that, one reason I like NWO/ Toledo. with the lake right there, it either all blows down wind towards clevland or out into the lake and who knows where then.

emmsions what???? I don't reconize that term???

same goes for nasty weather and storms, The lake acts like a shield. Only 2 block away N. I send all my snow to clevland federal express great lakes division.

 

You know, I happen to live in the area of Florida that DOESN'T have too many beautiful women. I'm in the wrong area here.. I mean there are some that go to my school...but you go to a beach here..you're outta luck for the most part. I need to move to Orlando...........

 

Tampa, man! Or down south... try Wildwood, in Sumter County.

 

Exhaust pollutants
Smog

 

I know, no reason to get mad, I was just stating that EGR is nonfunctional @ 2 points, idle and WOT, if I'm recalling correctly.

 

emissions is a moot point? which part, the 'moot' means (as the Rock would say) 'It doesn't matter!'

Emissions is what the EPA wants none of. It's everything that they (being ***) figure is 'bad' for the planet.

 

Unfortunatly they are partially quite correct on the call of what are pollutants.
I do want my 25 Month Old Son to enjoy what is still around and be able to breathe ALOT of clear air.
