Ok you have a controller in your dash, you want some boost for a race. You select your boost and set it in the controller. The controller sends the info to a computer. The computer reads from your MAF sensor. As the MAF sensor tells the computer how much air is flowing, it knows it wants more so it spins a fan (lack of better term) put somewhere on the intake to your desired boost level . The computer compensates the MAF reading so the car computer doesn’t screw up and throw a code. The supercharger computer knows it’s throwing more air in, so it sends something to the car computer and says “richen up the fuel”. So you have more air, more fuel, and you just chose your boost.
Sounds like the perfect scenerio, it would be high tech, in the beginning it would be REALLY expensive, but all it would be is a Fan (better term) and computer. So eventualy it would be perfect and cheap. If some company could make this couldn’t it be the ideal supercharger?

Am I wrong?

You'd be pulling more air in, but what makes superchargers and turbochargers work is that the compress the air. It makes it more dense, so more oxygen is crammed into the engine, and oxygen is what the engine needs. Your idea is pretty cool. With some more knowledge and work, someone might be able to make something along those lines that would work. Keep thinking. Hot-rodding needs people to come up with new and craz ideas all the time.

 

That actually does sound like a feastible idea though. I'm sure he meant some sort of compressor though... It'll be tough to get the idea functional. But you better get a patent on that idea! [ ] Honestly!

It could be a regular belt driven blower, but rather than be turned off the crank pully, it would be an electric motor that would turn the blower faster depending on what the controller is telling it to do. That way it would still compress air, and it would be adjustable on the fly.

Interesting idea, but I'm sure it would cost a fortune to implement.

 

I'm not sure if I understand this correctly. All I can think of that would work is if their was a valve that opens/closes (after maf) on the intake side to redirect air around a supercharger(which would have to have a clutch so it wouldn't spin while not wanting boost) and when you want boost you would hit a button which would lock up the supercharger clutch and close the air valve so air would go through the supercharger. That's a lot of work which would be similar in power and milage to a turbo. This fan that you talk of would have to be pretty high tech, no electric motor would be capable of putting out that much power to make a fair amount of boost and cfm without taking tons of amp draw.

 

While the motor taking to much draw is not completely true.

the company i worked for was a magnetics company, and the founder had made some brushless elictric motors, that where 3hp, and the size of a quarter, and took almost no power to run. if you had the resources to build, and design a motor yourself, it could be done, but it wouldn't be cheap at all. it would be much cheaper to buy a SC than it would be take the time and money it would take to build your own motor for something like this.

 

If I could come up with a laid out plan of how it would work, it would be smart to patent something like this, but then some company is going to make the same thing but a little bit different and patent will be useless

 

they key to that is they way you get your patent, if you had the patent on say "electric forced induction" or something not very specific, it would be harder for someone to copy it.

 

OK this whole electric motor supercharger idea is going to make me puke!!! Being a VETERAN of this board I have seen these crazy ideas come and go...I fought them and proven them wrong time and time again...(bilge pump blower...as I recall.LOL) OK you can get an electric blower to move ALL THE CFM"S you want but the WONT create boost....Why well Its easy....Because the minute the pressure gets to where it will build BOOST it will BACKFLUSH through the motor...The electric motor is not sealed or built ot seal up agains pressure now if it were Would it be able to overcome the Pressure of the boost...So the motor would stall and burn up at best...Find the moron who was buying 100 dollar bilge pump blowers and bolting them to his car...Yeah he flows 9,000,000,000,000 cfms he told me...But HMM he only got a supposed .05PSi of boost...I found that even to be suspect because the autometer gauge is not that accurate to that degree...Last I heard was a reduction of like .01 in the quarter mile...Hell weather, psi in your tires, weather or not you ate before you got in the car can make that difference. Bottom like is if YOU COULD MAKE BOOST using little electric motors and the cheap plastic fans inside the housings then VORTECH, PAXTON, or ATI are all Are really stupidin making their kits, They must have just overengineered their blowers...From now on everyone should just take their hairdrier and a roll of duct tape and make their own blower...GEEZE

OK after that rambling all im saying is it wont HOLDboost anyway...Id hate for someone to read this and actuall go buy a 1.21 jiggawatt power inverter and an electric blower and try to build a supercharger..

But flame me if you want but Anyone with a grasp of the obvious should see all the flaws in this system....If not good luck with seat foam air filters and ceramic muffler bearings..

No, No, No I knew someone would take it that way. I do mean an electric (Fan?) but in actuality I do mean compressor, and hell, there are some VERY high torque electric fans/compressors whatever out there.

In this theory I didnt mean to make it myself. I would/could never do it. I mean something that someone like ATI, vortech, or paxton might someday develope

and you could use electric to spin a completely conventional quality s/c compressor, they have plenty of torque to hold boost, look at the torque your starter creates.

 

I've seen an electric supercharger. It used a turbocharger compressor and where the exaust part would normally be, a motor was attached. If you do some serches on www.google.com you might find it. There are a lot of BS ones on there use using computer fans and all kind of garbage.

Ok, this isnt a flame, Im not mad about your criticism to my idea, I understand what your saying

But how are you a VETERAN you have 29 posts, yeah you'v been around since July '99 but I'v been here since Jan 2001 and have 363 and Im not even around that much.

 

Kenwood has been around a long time. He has been posting here long before the site switched to the UBB format. I know hes been here at least as long as me, and I first started visiting around August '97. In more recent time he hasn't been as vocal as he used to be.

 

yup

 

its cool, it wasnt a flame. I know it sounded like one, it was really just an honest question. I understand.

Let's drop the electrical boost thing, that is no good.

If I understand your question that was not the main issue, it was to be able to turn boost on and off.

You can use a standard turbo setup and have a computer controlled wastegate to control boost. You can set it to low and high boost from the drivers seat.

What about a supercharger then ...
I have a Vortech supercharged Cross-Fire. I designed it myself, and I can select if I want to use the supercharger or not.

I can route the belt two differnt ways. Like this to drive the suprecharger pulley:


Or like this to run the engine without boost:


When I want boost I only have to pop the hood and reroute the belt. It is a 30 second job. When I run without boost I still draw air thru the supercharger. I have not noticed any performance loss compared to using the stock air-cleaner assembly because the centrifugal supercharger in an open design just like a turbo, so it is no problem drawing air thru it.

The only thing I need to be able to engage the supercharger electrically is a clutch on the pulley like any A/C pump has. The problem is that the supercharger needs much more power than the A/C pump, so the cluch have to be stronger.

This company actually has an automotive supercharger (ROTREX) that is available with an electrical clutch.
