I looked for it... dident find it... so i ask you...
What are the Pro's and Con's of removing the AirPump..

 

Weight savings, less clutter, and your in FL so no Emissions

You need a double alternator pully.

 

or a yoohoo belt

 

why do i need a Double?
do i need to seal off the pipe left behind'? and um yeah.. duz it do anything els?

 

On www.1300cc.com I think he stated that there is a 5$ belt you could buy at a hardware store.

 

you will need a double belt because the water pump belt will slip at high rpm's , i had to find that out the hard way

 

Your exhaust will smell like ****. If you like that great. I didn't, neither did my wife. i had the airpump off with a cat still on until I ordered my replacement pipe (not a daily driver so the cat won't get a chance clog), I came in the house and my wife says 'your car smells funny', she was inside the whole time.

Lots less clutter though, and the yoohoo belt thing works.

 

If you remove the airpump on an S5 doesnt that kill your 5&6th ports?

 

I posted this awhile back. If you are interested in getting the second belt:

yeah, I wouldn't recommend using the Yoohoo belt.. as I think it was RETed who pointed out, there is no tensioner or anything, and it's either going to be really loose, or put weird pressures on your water pump and/or eccentric shaft....

 

That it does. The S5 ports are air pump driven, the S4 ports are backpressure driven.

Also, if you keep the cats & run without the air pump, supposedly they burn themselves up fairly quickly. I wouldn't suggest running cats without the smog pump, personally.

Really, if the air pump is working, there's no advantage to removing it, other than saving a few pounds & getting some crap out of the engine bay. It doesn't draw much power, and it avoids having to dig up a dual alt. pulley for the water pump.

On a S4 or S5 turbo, if you're removing emissions, go ahead & take it out. The smell keeps the tailgaters away (and if that doesn't work, a quick blast of flames does the trick). On a S5 NA, you need to keep it (or find another way to open the 6th ports).
