Air pump- Stay or get shot?

[hawker182]

Anyone removed their airpump?

Mines decatted and there is no use for it but does it weigh enough to go through the hassle of removing it. Wont be a hard job and will free up some space in the engine bay, but if it only ways a few feathers will leave it be!

It takes 10 minutes max to remove it.....
 
 Get rid of it...........

I\'d say if you have a twin Alt pulley and a block off plate get rid but it makes absolutly no diffrence if fact my car ran worse when it was removerd (duno why may be an air leak or somthing).

The Pump its self is lighter than an Alt but at the same time it will help air movement around the turbo area.

It will make a difference, wether small or not, it will make a difference...  Anything less the engine has to drive is better all round!

 Can you embellish on this?

 The fact that you have a problem with removing yours is testament that YOu have done something wrong and should check yours first.

So i understand how to remove it without a hitch, i am right in sayin that i just need a new belt fitted yes?

[Grizzly]

LOL

Ok, Let me put this a diffrent way. That car was a pain in the rear from day one.

Try this one, i bought another t2 that had been done by a well known Rx Tuner. I drove this for a month before it started running badly, it turned out that it had blocked the cat. can you guess the Air pumps main purpose in life?

I would still say if you don\'t need to remove it don\'t.

But i have had an experiance with an FD where the air pump failed causing it to lock up and i lost the belt! This was bad as i was 100 miles from home but that and the sligtly better air flow is the only reason i can give you to remove it.

Don\'t take it from me do a bit of reading up on it. Dubble Pulley is a Min then you have the fact the stock EMS thinks its still there so it will run rich on idle.

DO NOT!!! remove the air pump and not put a twin belt pulley and extra belt on. The fan takes some turning and it is connected to the water pump. so the reduced belt to pulley will make it slip when you wot it.

This i have also seen first hand, v belts are rubbish, you look how much the water pump relise on the Air pump belt.

Right will look into it a bit further 1st, any interesting stuff i come up with will post here. cheers

"It will make a difference, wether small or not, it will make a difference... Anything less the engine has to drive is better all round! "

Buying an electric fan will have more of a diffrence!

Yes did think this also but will go down that route when i get a new rad and front mounted IC. Of course this is a long term plan. I was only really thinking of removing it for the fact that it will create more room, espeically when i\'m trying to fit a cold air box for my induction system, is pretty limited in there as we all know

[grinder]

makes some interesting reading to be honest

once im running a full decat im hoping to remove the air pump - i already have the dual alternator pulley - so that helps

and im getting some prices for some more to be made up

we could do with some instructions anyone on how to remove and what block off plates we would need

i have never heard that you need plates - all i was lead to believe is that you need a bung for the air box ( if you still have it )

not sure about the other end though

this is a good thread - and will provide good reading for all new comers

Ok found this but couldnt seem to link to it, hope it helps

2nd gen Airpump and ACV removal (turbo II shown)

 

On a Quest for more space under the hood, and maybe even a tiny bit of HP. Our eyes stare right at the airpump and ACV. These combine together to lower our emissions, but with no cats, don\'t do a dam thing (except open the 6 ports on the 89-91 N/As...)

**Note removing these items would be illegal for a car driven on the street....

 

Removing the air pump is very easy, just a belt, a few bolts, and 2 hoses.

First step pull the hose off between the airbox and airpump (of course by now you probably don\'t have an airbox, so you should\'ve had a small breather filter on the pump, remove that.) Remove the bolt where the arrow is, and loosen the one at the top of the airpump under the rad hose. Now the pump is loose and can move side to side. Push it towards the engine and now you can slide the belt off. Then you should be able to slip the belt over the fan (or cut it if you want...) Now remove that top bolt (pump will want to fall) and the other 3 that are circled for the air pump bracket.

It\'s a bit of a trick to get the pump out, it\'s pretty tight in there with the stock fan and rad hose in place. As you wiggle it around you need to get another hose off the back of it.

Air pump removed, look at all that space!

[hawker182]

At this time it would be very wise to spend a few bucks and do this mod while you are in there.

 

Now with the Airpump gone, the Air Control Valve (ACV) is useless, as that is where the air went to from the airpump.

**Note, before you start you will need an ACV and spilt air pipe block off plate. I got mine from //www.k2rd.com

You must ensure you have blocked the air bypass system into the inlet, otherwise the car will die as soon as it starts up. (assuming there is a sensible block off point like there is on the egi)

 I\'m running no air pump and an electric fan on my EGi (thats for sale by the way )but then I\'m also running a straight through system too.   If you\'re in any doubt dont touch.
