A performance shop in new Braunfels texas blocked off the egr valve and removed the egr code from my computer last year. I just haven't had time since then to do anything else... They told me to delete the rest of the emissions crap from under my hood as well to clean things up.

Anyone else done this? What all can I delete?

He told me not to delete my A.I.R. pump because it is a very solid pulley... much better than the aftermarket junk. He said just to open it and break out the fins inside so there is no more drag on the pulley.

 

What do you consider the rest of the emissions crap?

Besides EGR and A.I.R everything else is essential for the engine to run efficiently. All other sensors lead to proper fuel management. If you remove MAT/MAF/O2 or whatever other controls are there it won't run. If it's legal in your area I'd leave everything else in place and remove the cats.

 

I should clarify...
There is more to the EGR valve system and and air pump than those components themselves.

I am not referring to Map sensor 02 sensors or things like that.

 

Catalytic converters, AIR solenoids and check valves, and then you will need a tune. Then you should be good.

 

Just hope they don't change any smog laws in the future.

 

Yeah, San Antonio doesn't have any and I am only 2 years away from completely not needing to worry.

But things could change. I will hold onto the parts just in case.

 

I have done the following on my 87 for same reasons, old and not required in Florida.

AIR Delete (TPIS KIT), EGR Delete, Cat Delete, new exhaust manifolds, ECM reprogram, and a lot of hours tuning. It does clean up the engine bay but again it isn't necessarily right or legal everywhere.

I personally don't like the idea of opening up the AIR and braking it, something just seems wrong with that concept. Especially when you might sell it to someone who needs one.

With ECM reprogram and tune I do not have any CEL and yes the bulb is in place and not burned out....

Best of Luck....

 

I vote rip that crap out

 

just for laughs even though you may not be checked in your stat it is still a fed penalty for tampering.

 

In 10-15 years all that stuff will be worth big bucks to collectors (because most people trashed it).

 

We had an expiration date on the smog checks in California…then they changed the laws. I'm still doing smog checks even though the car is over 25 years old.

You can remove the vanes inside the smog pump. There is no "breaking" involved. They float in slots in the impeller and just pull out.

 

I live in eastern Kern County. Even though my EGR has gone bad it still passes. It's a good way to see on paper how it's running with regard to HC. My 90 is running very clean right now. Not being in an "enhanced" area we don't dyno test here. If we did they'd discover the EGR problem. It's just the valve diaphram gone bad. I've been too lazy to replace it.

Also if I move 12 miles north to Inyo County I would have to test it at all except for resale.

 

The state sure pulled one on us. I had a 460 police interceptor ready to go in my 77 ford and just as the rolling 30 limit came up on it the A Holes changed the smog laws.

 

A few random thoughts...

Emissions from 1985 are, at best, crude. They served a purpose... but that is all moot now, because the hardware is breaking, losing functionality and simply, junk.

First off, EGR is not the enemy most people think it is. What EGR does is two fold, one, reduce NOX emissions, which is huge towards stopping acid rain. But the thing it does for us is reduces knock! What fixes NOX also fixes knock - re: detonation!

Cats on the 85 are a joke... you have one central unit which is nothing more than a large choke point.

If I had an 85, this is what I would do...

1. Ditch the air injection, all it does is light off the big cat faster.

2. Headers

3. GOOD bullet cats - they don't rob any power, help maintain back pressure and help improve scavenging by cleaning up the exhaust flow. Random Tech or Magnaflow, spend the extra coin and get the CA certified part, has a better warranty.

4. X-pipe... about where the cat was, give or take. There is a science to installing an xpipe. It has to do with finding the hot spot, which is where the turbulence is.

5. plumb out the back... the C4 cabin is a resonance chamber, so I wouldn't go with elims. Something quiet, but it will still sound stout.

6. Intake manifold... the TPI is a mess...

Do all of that and the car will run cleaner, get better MPG and get this - pick up 60 hp. Just by letting the damned thing breathe...

Also, a friend of mine came up with this kick-*** air pump eliminator. I don't know if he plans on make them, or what not, but...

Air Pump Eliminator

One final thought... and a little preaching... most people don't realize this, but federal highway funding is tied to your regional emissions output. They can come down on you real hard, regionally, if the area starts to stink, and there isn't any testing.

We, as gear heads, could get ourselves into a heap of trouble if we don't practice a little bit of due diligence. In short, if we all removed all emissions from our cars, and the pollution numbers shoot up, then we only have ourselves to blame for the impending anvil from the sky. A little self control beats the hell out of more government regulation.

 

Actually going to configure a smog pump on my 67 A body next yr just for laughs, small import pump oughta do it (polished of course! lol). Custom billet bracket and one stainless line running to one cyl on ea side;chris jones racing will set me up with the pulley
Theres a way to make it look clean. It is still a smog puking machine but Im always wary of CHP those are usually the ones who can take the car if the stuffs missing;they can and will check, good luck getting your car in one piece out of impound been there before!!
Technically it just has to be there not even working ie a pump held to the head by a bolt thats it.
Should be good for a laugh or off colored comment or two at the track/cruise night cant see any power loss .What 2, maybe 3 whoopee

Point is unless youre taking it off for seeing less stuff underhood you wont gain an ounce of power or any youd feel removing it. If only I had the setup I removed from it yrs ago, tossed it out. Irreplaceable!

 

Pre 1968 is totally exempt... Not even the EPA can touch you.

CA may have mandated it, but I don't think they can even enforce it... Namely, they can't prove the car was a California car from day one any more.

And CA regs didn't have the ***** they got later to over power the EPA regs. Meaning, pre-1975 or so, CA required more emissions, but they couldn't deny another car entry, like someone moving. They got that power later, but it is limited...

I will have to double check the regs...

I wouldn't worry about it.

 

Pretty sure they can check underhood refusal is a tow and impound.
Supposedly they CHP and po pos took classes on spotting it a few yrs back. Had heard they tightened up the laws after all this fast and furious bs was put out there.

what Id worry about is some badge that didnt really know the laws and took er away.

Id be curious to see what you find.

Last car I had impounded was a 70 Z/28 fresh frame off. When I got it back it cost over $1000, motor had a wrist pin knock (once I got it running again), rearend was blown, intake carb console valve covers etc were all missing. There is nothing you can do, I got laughed out of there and threatened by the law if I didnt have it out in 15 min they would arrest me. I had to push it down the street. Van Nuys circa 89/90 something like that. Car was destroyed; I was super po'd and made a scene
At least it had a smog pump on it

 

Wow, you guys got some harsh HP guys out there in CA...but there again I know the emissions laws out there are crazy too!

 

I say rip it out if it aint needed, the state/county don't require it and you have a great tuner. EGR delete, replaced manifolds w/ full length headers, no cats and even sometimes, no mufflers(electric cutouts lol)...Fortunately, I have a good tuner who was able to tune it and of course shut certain sensors off...
