Hi. Has anyone done an air pump delete and still passed the emissions test in Maryland?

I'm in the middle of an Intake/TB/WP refresh, and I'm thinking, boy wouldn't it be much cleaner looking in here if this air pump and associated crap was gone?

Just wondering.

LMAO! Not quite the "solution" I was hoping for.

My '85 passed just fine without the air pump hooked up, back in December. I'm not sure what the actual difference was from the first time through emissions since they changed the testing procedure from when I first had it tested in '07 so the numbers don't match up.

Now THATS the information I was hoping for! Thanks Jim!

Kiss that air pump GOODBYE!

Why remove something that is an integrated part of the overall induction system of the car? It helps your car run cleaner with almost no loss of hp.

Well mainly because I have to take most of the system apart to replace the passenger side cam cover and if I don't have to put it back it will save me some time and potential headaches. Also, one less system to maintain and/or break.

As long as it passes the emissions test, what's wrong with that?

Just as long as you don't get a tech who knows 928's:

(from MD state web site: http://www.mva.maryland.gov/AboutMVA...issionscontrol)

"Emissions control equipment

[Return to Question]
If the emissions control equipment is not present or has been disconnected the vehicle will not pass the inspection."

My brother's '89 S4 passed no problem with a disconnected pump belt.

If tail-pipe sniffer tech is that familiar with the 16V 928, he's probably an enthusiast or better yet a fellow owner. Either scenario will most likely work out in your favor.

Can we move past the “holier than thou “ BS that always seams to tag alone these threads?

As long as the tree-huggers are recommending everyone go buy oil burning scooters to save the world (ever see the blue plume pouring out of those?) or hybrids with batteries produced by a process that is far more mother earth damaging than my tail-pipe, I’m not going to worry about the emissions of my less than 5,000 mile per year vintage sports car.

My boat on any given Sunday does fare more damage to the environment than a non air-pump 928 could ever be. Funny part is my boat is 100% compliant!!!!!!

Ever see a fully loaded semi pulling away from a stop sign?? How many miles would I have to drive my 928 without cats, air pump and just for fun leaded fuel to equal the amount of crap spewing from that stack over the span of 100 feet? How many miles will that rig do in a year? 200,000? 300,000?

Wake me when the real problem of our dirty air is going to be addressed and leave my cars alone.

Someone pissed in Hacker's wheaties... wasn't me.

Hacker: I didn't write the law, but I happen to agree with it. If you've got a problem with diesel solids limits, or lack of enforcement for recreational vehicles, call you congressman.

FWIW, I have failed emissions in the past (in Colorado) because the check O2 sensor light didn't work, because I'd switched to an aftermarket speedo cable connector box after the stock VW one wore out. The O2 sensor itself was fine, the car's emissions were fine, but I failed because a little mileage-based reminder light was inop.

Some hippie in a VW Bus cut me off on the way to work this morning.

Why is it most of the "save the planet" bumper stickers are on the back of cars spewing out colors of the rainbow I never knew possible from an internal combustion engine?


I agree with the idea of clean air standards, I'm sure most people do. Problem is we are going at the problem backwards. Fact is we are spending 90% of our efforts going after 10% of the pollution.

Yea, I forsee anything changing for one of the largest unionized industries in the USA. Pipe dream.

I'll be having drinks with him this weekend. He's doing what he can but we both know the reality of the situation.


February 14, 2010 over 7,000 gallons of fuel was burned in Florida for entertainment purposes in less than four hours. It will take me over 10 years to consume that much fuel. So please wake me when Bob's 928 wthout a smog pump becomes even a measurable threat to the planet.

linderpat

I agree with Hacker. The "clean air" guys that rag on a low mileage vintage car's potential, theoretical emissions pollution due to the elimination of an air pump or cat ought to peddle that drivel over in the industrial sectors of India, China, Russia, or wherever there is real pollution. This is the same mentality that brings out the nut job bueracrats to declare that CO is a pollutant - so let's all stop breathing and kill all the plant life that emits CO during the day.
If you are really serious about pollutants, sell the shark and ride a bike (but don't exhale). Everything else just smacks of hypocrasy to me.

FWIW, my '87 passed Texas smog with flying colors. No smog pump, chips, high flow cats and headers. My understanding is these engines run very clean. I believe I heard there are some dallas folk passing tailpipe without cats. Go for it Bob!
