I have taken off my smoge pump and i had no problems at all. The computer won't post a code because it won't know it's gone.

Hope that helps you out,

Ditto, welcome to Thirdgen.org. I have taken out my AIR pump as well. Just plug the AIR tubes on the headers and your set. It would probably be a good idea to drop the cat too since without the AIR it clogs easier (AIR system helps cat break up Hydrocarbons). Email me if you have any other questions about it, I will try and help you as much as I can. It's pretty easy though, just make sure you have both Metric and SAE sockets. You need to buy two 1/2" pipe caps to replace the check valves on the headers.

 

thanks for the help guys. my cat is already gutted so that isnt a problem

What is the purpose of removing the smog pump? Will it increase my HP?
Thanks..

 

Removing the pump will do three things. First, it will reduce some weight in the front end of your already way too nose heavy F-body. Second, it will reduce parasitic loss on your engine because it doesn't have to spin the pump pulley any more. And third, it'll unclutter your engine bay. You probably won't feel a difference but you'll definitely gain a few horses, and they add up after a while. Every little bit helps . What you will notice though is much cleaner and more open engine bay which is well worth the time.

 

I have my cat removed already...If I'm done with the rest of the problem with my car I will try removing my smog pump also, just to clear my engine. I have learn so much from this forum and I enjoy learning new Ideas
thanks..

 

No sweat... thats what we're all here for.

After Removing the Smog pump, can I still use the original belt?

 

The part number for the belt is Gates #K060935 if you are using power pullies. I'm not sure of the number without pullies. Maybe someone else can help.

 

#2 is next to nothing. If you do it, you won't notice any difference in 1/4 mile ET, for instance. I know, I kept track of ET's before and after - zero difference.

Who cares about a power increase. The point on the entire assembly being gone in your engine bay is WELL worth it. I did away with my AC also. Check out a shot of my engine bay(in the signature).

Just like to add my 2 cents as one more guy that's happy with his decision to remove his smog pump.. goin on 4 months without it and no problems. I'm keeping an eye out for signs of a clogged cat, but plan to replace it soon anyway

 

Welcome to the group man! I tell you it is worth it to remove it just to be able to see the passenger side valve cover again!

Maybe this is a lame question, but can removing the smog pump decrease the life of the oxygen sensor?

 

Not likely. The A.I.R. only goes to the manifolds when the engine is cold. After that, it all goes to the cat.

 

I've heard that removing the air pump actually decreases power. Something about it helps evacuate the exhaust quicker?? Only heard that once before. Does it make sense?

 

i have never had emisions on my car... previous owner took them off. but i do have 1 question... the two connections to the smog pump... dont this hook inot the computer? if they do, why wouldnt the computer know theyr not their?

later

well i removed my pump...

No codes... so obviously it doesn't see it or doesn't care... or doesn't read it.... im still in the process... wating for some more answers


The coolant bypass has nothing to do with the smog pump RIGHT???

and i need a part number for the belt to use after removing the pully...

AIR pump and plumbing gone, no codes, the ECM does not check to see if the solenoids are hooked up. Take off the belt, and go to local parts store and ask for the same thing but 1" shorter.
Installed a hi flo cat too, muffler shop assures me that the newer designs will not clog as they are built to work either with or without AIR.

Next, on to the coolant bypass.

Cheers

The computer is clueless to the fact that the pump and air divert solenoid are gone. I've hooked it up to a scanner and watched it; the computer is just commanding away, completely oblivious to the fact that there is nothing to recieve it's commands. Very cool.

BIg question here guys, first, how do you remove the smog pump and second, will the car remain street legal and still pass inspection?? I live in Virginia, own a 305 TBI.

 

This is my engine minus AC and AIR . It still passes e check.

Correct me if Im wrong...

!st there should be a FAQ and/or a tech article. Second...

the smog pump/AIR system pump oxygen into the exhaust manifold to keep hydrocarbon of the exhaust ports

I thinks thats what it does...


am i right?

 

There is a tech article, but its very very lacking in detail. And confusing. I am researching this, becuase I think its something I may wish to do. It may be a month before I do it, cuase inspections are soon. But i will make notes, and take pictures and write a full article once I'm done and share my research.

 

good that will benfit us all and I would appreciate it... Thanks....

 

Sounds good man. I will look forward to a detailed tech article so I know what to do when I remove mine.
Later

I removed most of my air system also. I just kept the pump, but ran a hose from the pump outlet straight to the CAT air tube. This still lets you lose the bulky manifold tubes. You can also remove the air management valve. Just plug the vacuum lines and tape up the connectors. It's not ECM controlled, so no "Check Engine" light, and you're legal. Don't have to worry about clogging your CAT over time either.

hey unforgiven89,In virginia you will have a problem and never pass a underhood visual inspection unless you know someone.If your car is a sports car and older then 1994 the first thing they do is lift the hood.With this in mind Ill keep the pump and take the 1hp lost ,if that.I dont need to see my valve cover.
