I did my headers and never disconnected the power to my AIR pump(it makes that cool whistling noise and now it's even louder with all of the lines cut).

Is there any way to turn it on all the time and route some type of tubing to the air box and make this thing useful?

I know I know just pull the stupid pump but I was bored the other night and was just thinking of stupid ideas.

Does it put out enough air to do anything?

Well, still have mine - when I grab the air tube filter (when the pumps on) that originally went to the air box I'm not impressed with the flow. Plus it draws a lot of amps while running. Not worth messing with IMO.

That's good enough for me, thanks.

You can just pull the fuse or just pull the whole damn thing out too. Its really useless if you run an ORY. It takes off a few lbs. too! Just a thought for you.

err ok

Yes you could route, and NO it is of no use. You simply can not force more air into an engine in that mannor, what you need to do is COMPRESS the air, so you get greater mass for the same volume, i.e. fit 2 cubic litres of air into a space only 1 cubic litre big.

not true: roots type blowers don't compress air they simply move it, and while they aren't as efficient as twin screw designs you can't really argue that they don't work

OP, to give you an idea of why it wouldn't work, the biggest disadvantage of superchargers is that they rob horsepower to run, and I've heard as much as 40hp on a mildly modded engine. So your talking about a blower working so hard its taking 40hp to turn, or about 25hp less than a VW engine puts out altogether. Something tells me that little 1/10 HP air pump isn't going to do much

You can hear my air pump when it's on and shuts down and it makes people look at the car funny...what's hard to understand?

yea pple give u that "WTF was that" look...jus tell them nah man thats my mini PROCHARGER i have hiding in my FENDER behind my turn signal.....lol

A Roots style blower may not be a true compressor in the sames sense as a twin screw or centrifugal, but it does this compress by forcing the air out of a smaller outlet under force, this is why they tend to be less efficent.

by that definition anything that moves air could be a compressor if it encounters resistance, and the AIR pump would qualify

Yes it was not a technical definition of a Root's style superchrager. But the difference is it DOES compress, in contrast to blow. A pump most likely does compress, but the AIR pump does not have sufficent volume of flow.

But take a fan (office desk type of thing) these do not compress the merely move the air and increase it's velocity.

no, a roots style supercharger just moves air, it does not compress it in itself. Do some research if you don't believe me. The compression happens at the outlet port where the air stacks up against the engine inlet system, the blower itself (which is WHY they call it a blower) doesn't compress anything like a centrifugal or a twin screw supercharger does. If you had no intake system to stack up in, there would be no pressure period.

Try this for starters if you don't believe me:

screw that airpump.. mount a leaf blower in the spot and reroute it to the intake ... ***** to the wall..

did anyone see that streefirevid of the leaf blower on a dyno?

yeah that was pretty damn funny...scary that it was actually worth some HP

I believe I said something similar to begin with.

The roots is positive displacement. The faster you turn it the more air you force into the intake manifold=====>Boost that was my understanding.

Anyways. When is the 'Air' system operational. I always wondered since the o2 sensors are gonna see that additional oxygen in the exhaust. I would assume just when the car is running in open loop mode. Is this correct.
