Update on the air-pump supercharger.
Well I found out how to get the frigging thing apart today and I found that I can make it pump much more air by using a couple well placed cuts. I'm going to mod the inake and output on the air pump, ue some bigger hose to match and see if this baby will work. Wish me luck and please don't bash me for having *****.
Peace out,
Charles

peacekeeper: How did you manage to finally get it apart? What are you planning to do, port it all out and update the fan(or whatever is inside of there) or does it have a pretty sufficient flow already just needing to be opened more? Come on man, spill some details here!

It doesn't have the flow to creat boost right now but it will soon. There is this cilydrical thing that spins in the middle of the air pump. It has these metal peices coming off of it that make the compression. I have found that by increasing the size of these "trenches on the air intake side of the metal pieces, that more air can be pushed/pulled in to creat more presure. I have some tools that I will be using to machine these new trenches. And yes there will be some porting and matching done for better flow. I couldn't get it apart because the back cover and the pulley connector were pressed together by a press so I got a puller and removed it. Oh jesus it was a B-i-t-c-h. to get off. I will be fabricating hoses that I will run fom the pump to the intake,and from the pump to the exhaust. The exhaust side may have to have a regulator atached to work the 6 ports properly. Don't know yet. I will take some before, during and after pics as soon as I can. But I will take awhile to post them cause I don't have a digi cam. Haveing the extra psi come through the 6 port actuator thingy or what evr you want to call it wont hurt anything will it? What am I missing here. I don't think I will need to mess with fuel will I? I don't think I'll be running that much boost. I need your feedback. I hope this works. I'm gonna get the car dynoed before I try the mod and after I get it done so we can see if it works or not.

I would really like to know your thesis for this project. For example, how you propose to feed the air into the intake, what modifications you are making to the pump (ie "well placed cuts"?), mathematical equations which estimate the required mods and expected performance output, etc.?

okw ell it may be a fun endveavor(sp) but you cant just put presiruzed air into an open intake, it will just blow out the other end. Turbos work becose the entire intake is pressurized, your jsut blowing air into the intake, so instead of say 12 CFM of air going into the intake, it only sucks 10....
its not going to pressurize anything, but goodluck with yoru project

Jesus christ, you guys just can't leave him try something out. Who cares if it doesn't work, at least he's doing something more than sitting here being an ***.

What the hell, he lives in America, our school systems will just make him stupider. Also, your intelligence doesn't seem very far reaching, considering you couldn't comprehend the "please don't bash me for having *****" part of his post.

im hoping it works for him (even though i really doubt it will) i need to make some money, and if modifying my airpump to be a supercharger is the ticket, then so be it.

*shrug* ignorance pays off sometimes And it still doesn't change what I said any less, but anyway, he didn't post this thread to start a flame war so I won't try to pour gas on it. I personally don't think it's possible either, but that doesn't mean I'm going to be an *** about it

I am on the same side as everyone else here apparently. I highly doubt it will work either. But, it may work in some fashion. Just because it doesn't kick up 8 or 10 psi like a true supercharger and it doesn't give a full 35% increase in power, what if it gives 4 psi and he gains say 10 hp.
Wouldn't that be worth doing to your old air pump, to gain 10 hp out of a thing that has the reputation of being the first thing to be yanked out of the system? Hell, for 10 hp (or even 5 hp) I would mod mine in a heartbeat. The thing is useless to me (no cats left), but could make me a little more horses under the hood.
I am extremely proud to know a forum member like this is willing to try something totally new. I hope to god that this works just to kill some of the negative comments.
Good luck to you man and keep me updated on your progress b/c I am truly intrigued by what you are trying.

It won't work. There will be no gain in power. If I were you, I wouldn't waste my time with this. An air pump will move enough air to supercharge a single cylinder 3.5HP lawnmower engine. If you put it on a 5HP engine, it becomes a restriction in the intake. I did this on my go-kart. If the pump cannot support a 5HP piston engine, it will not even come close to boosting an engine that moves air like the rotary. It's like blowing into a wind-tunnel.

Well I've never opened up a Air Pump
But if you can get it to create positive manifold pressure@ at least 4 PSI/550cc sec Injectors
You could gain 20+HP
The 1st Gen guys had this Idea too hehe

well I cant bash you for trying I dont think it will work but good luck, what about amming the air pump line into the intake b4 the throttle body?? but that would put stress on the TB but just a dumb thought

However...
A little thinking never hurt.
How about flow rate of the pump?
Do you know how fast it would have to spin to get 1 psi boost? That RPM would be catastrophic.
And what about the heat build up?
How about the flow restriction of having all combustion air squeezed into that air pump tube diameter?
How can common sense be so easily abandoned?
He gets none of my respect for putting mouth in motion without putting brain in gear.

Why dont you just let him be- ****
It's stuff like this that starts from little ideas, that make people rich! Just let him be, encourage, not discourage. Now why dont you take all that negative energy and go lay some rubber
