I just read the tech article. Is it talking about taking the whole thing out, or just re routing stuff so that it's non-functional. We just got rid of emissions testing in OK and I'd like to do whatever I can to free up space and horsepower. BTW, the smog pump is that thing right behind the AC right?

 

Its actually under the AC on serpentine belt equipped cars. One of the pics in the article is mine, the entire AIR system is missing from the car. You will need some plugs for the exhaust manifolds (if you have those), dont quote me on this but I think the size I used was 1/4"NPT. Its actually 3/8"UNC, a normal straight coarse thread, but the only sort of 'plug' you will find in that size that will reach all the way is a bolt, and since the inside edge is a taper seat the bolt wont seal it off too well. Use brass plugs and they will stay in and deform nicely to prevent any leaks from the manifold. You will also need to block off the air tube to the cat, I wouldnt remove it unless you feel like going through an exercise in frustration, as it does not really get in the way of anything. That will clean things up alot, and changing plugs will become much easier.

Important point to note:
I keep hearing and seeing people break off the bolts for the smog pump, the ones that hold it in the bracket. Lots of PB Blaster or WD-40 or whatever you use might not be a bad idea, and some patience to take them out properly. Giving some solid but not real hard taps with a hammer helps free up frozen bolts, you might try that too.

I just remove the hoses and reroute the belt with a shorter one, this way when Inspections come once a year I slap those hoses back and put the old belt on.

 

I just pulled the vanes out of the pump and put it back on. No short belt needed.

 

I removed mine completely, hoses and all. I couldn't keep the pump on the bracket or it'd be in the way of the belt.. took quite a bit of patience to get those bolts out of the pump, but it came out fairly easy. as for the hoses, I think I used a 3/4" heater hose cap on the AIR lines from the manifolds, and clamped them down good with the stock clamps that were on the hoses to begin with.. I also removed the line going into the cat, which wasn't too much trouble, since I have no A/C to get in the way. it's only held in by a couple bolts and then you can just clip it at the cat and seal it up. I actually bought a new cat and put it in, so I didnt' have to worry about sealing it off.

by the way, my car runs almost perfect emissions, even with no smog equipment.. not that that matters... I like being an inspector

atcually its under the a/c not behind it. Its the pulley thingy right under it. Its very easy to remove. And it frees up alot of space once you take it out.
