How hard would it really be to make a super charger?

I suppose that the most difficult part would be to get the AFM to handle the boost so you'd need somekind of computer and fuel injector mods.

Also you would probably have to cool it down somehow.

But the way I see it, at its basic idea, is that you have a belt driven fan that simply shoves air and gas into the throttle body as opposed to the engine just sucking it in.

I also wonder that if you did supercharge it, inwhatever way, what type of exhaust mods you might need for the extra added output.

 

I think that hardest part about making a super charger is fabricating one, better yet, designing one that works well.

 

yeah I would agree. Don't the tolerances have to be super close in a s/c? It would take a lot of engineering that most of us do not have the ability to do ourselves. But I say that if you got it, then go for it. I would love to see how it turns out. I am a big fan of chargers and I am planning to put one in my GXL this year coming up. I would love to see what you come up with and I hope this wouldnt turn into another "tesla bladeless-disc s/c" thread haha

 

Maybe you could use a camaro supercharger and put it in the place where the air pump was/ is.

Only picture I found.

 

It would be pretty easy if you have a degree in mechanical engineering and a machine shop, just as long as you stick with a simple Roots-type design, or maybe a vane type. A Lysholm or Eaton type would be more difficult, as would a centrifugal or G-Lader supercharger, but these are all possible with a good machine shop and the proper skills. I wouldn't recommend trying a Tesla supercharger, lol.

The whole idea sounds difficult to me. FYI a turbocharger is a type of supercharger. Therefore, the cheap and easy method is to get a job at Burger King, and simply buy a TII once you save up $2,000-4,000.

 

A supercharger is basically just an air pump? What is different (basic concept here, not specifics) between a roots-blower and the air pump that is on nearly all FCs? Could the air pump not be used as a type of supercharger? Or maybe I have the concept of the air pump all wrong.

 

A Roots blower has two parallel lobed rotors that mesh with each other. I'm not sure about the FC air pump, but it has a cylindrical casing which could indicate a vane or centrifugal type of compressor.

The air pump on the FC will not flow enough air for the engine if used as a supercharger. It would almost be like trying to use the windshield wiper motor in place of the 13B motor because they are both basically "motors".

The FC air pump is a vane type. took one apart when I got bored. looked like it used carbon fibre fins.

 

Thanks for those links Evil,

Especially the one on the supercharger. After reading the airpump supercharger I am now going to put Nitrous on my lawnmower.

Anyway, I see why the difficulty is highly technical.

I thought that a belt drivben fan of somekind would be a possible starting point for something like this because It'll take me a while to save up for a Atkins SC.

But conceptually speaking if you want to actually provide boost you have to have a fan mechanism that basically compresses the air so that when it enters the intake duct and it then exits much much fast than when it came in. Therefore a puny fan would really not be suitable to build enough pressure......A fan might just kill HP.

However, going back to ghetto engineering. What if you designed a system that compressed air into a tank that then once at 120 psi or something, could be fed back into the intake duct?. Like the compressor for an air nailer that was electrically driven? You can buy seperate air tanks that just simply hold air. Then maybe you could put it back in the hatches behind the passenger seat. And the compressor motor in the drivers side one. Get a power inverter and supply the nec voltage to the compressor. But then again I have no idea how much PSI would be generated from the feed hose. A standard hose is like 1/4 inch ID. I suppose that you would need more than one. On the other hand you could also completely seal up the front of the intake duct so it could build pressure with the hose connected there. Again I have no idea how much actual PSI would be realized there if any.

I donno just ideas. I like to experiment with stuff even if its totally stupid.

Thanks for your time.

 

what if you replaced the A/C and the Power Steering with more FC air pumps, and routed them to the intake duct?... this is also a cheap ghetto engineering idea. Any takes?

 

Oh my, air pumps again as superchargers.

 

Oh my, air pumps again as superchargers.


No, this clearly isn't an option. Nor is a stupid fan.

To answer Neptunes Q, I think Evilaviator put it very well: An airpump as a supercharger is the equivalent of a windshield wiper motor as replacent for a 13b

So three or four or 50 windshield wiper motors aren't going to cut it either.

 

Again after thinking about it for a little bit longer I suppose the best place to start is to understand how much reverse PSI (uh, yeah reverse PSI) is generated by the motor sucking air through the intake.

Find out that figure and then I suppose you'd know what you would have to feed above that to get an extra 4-6 lbs for safe boost.

I mean lets say the motors sucks at X lbs of suction.
Then the pressure you'd need would have to equal that suction plus provide another 4-6 lbs in excess, continously and also be agregate according to the RPMs?

Right?

 

Well when you messure psi when boosting.. would be the same as messuring Vacuum + Psi..

Example... You super charge puts out 6 psi at 5000rpms, Say you have a boost gauge and the vacuum before super charger was .5 psi.. Your boost guage would read 5.5psi... so it's point less trying to figure out vacuum..


I could be wrong.. but I did get a A in physics.

 

When I said oh my air pumps as superchargers again i wasnt supporting the idea bud. You probably hadnt even registered by then, but there was a guy on here a while ago who thought this would be a brilliant idea. Everyone told him it would never work but he insisted on trying it. Nothing ever happened with it, maybe he tried it maybe he didnt.

 

It sounds like some of you bright young folks are attempting to re-invent the wheel, lol. I think you would understand things better if you had some education in the subject area.

Well worth the $25, even though it is written for piston engines:

Not quite as good, but it's free:

Those of you who actually like this sort of thing may want to consider a degree in mechanical engineering.

That was in one of the links I posted. There was no chance of it working because his design was not an enclosed system, and any small amount of pressure produced by the air pump would have equalized out through the intake. Fortunately, the air pump corroded before he had a chance to waste any more of his time with the project. BTW, if you read that link, you can see my great idea for a windshield washer supercharger, lol.

 

ok i dont know if any of my friends have tried this but i once heard them talking about taking an air pump off of a big pickup truck like an f250 or something and switching the pully with a really small on so that it would spin like crazy and using that as a supercharger. the friends that were talking about it i dont talk to much but they both have alot of car knowledge and experience so it might actually be worth a try

 

The Air pump will not work as a super charger.. but you might get a better throttle response.

 

I'd just go with something out there and then change what was needed(i.e. cs supercharger)

 

...When I said that I was just throwing out ideas... I didn't mean to get everyone fired up. I was just trying to say that they both do indeed push air one way or another, flow rate and volume being the difference... I suppose though, that if one could design a housing properly, a few of these air pumps (perhaps with extended blades, assuming they use blades) could be combined to create one supercharger. I don't know alot about it, but I guess what I mean is that it can't hurt to have extra air being placed inside your intake, even if you're not using it as supercharging... perhaps you're using it to help fight water suction or something.
