i was looking on ebay at superchargers and i found this

http://cgi.ebay.com/ebaymotors...=WDVW

its and eletrical supercharger and i think its a buncha of BS but does this actually work?

 

its a noisy POS, HMT did a test on it, it wasnt worth it.

 

It's not a supercharger.

Um, yes it is. The def. of a supercharger is an air compressor that compresses air which goes into the Intake of the engine. Thus raising your compression ratio about 5 (depending on your setup) atmospheres. A turbo charger is the same thing as a super charger, just it is powered by exaust from the engine, where as a super charger is powered separetly (which has no lag like a turbo). Now, usually a supercharger is powered by a belt (like ye olde alternator or AC compressor), but this one is powered by electricity i guess. Which would explain the noise, and lack of effectiveness. (imagine the power lost from belt to alternator, then from alternator to wire, then from wire to ANOTHER electric motor to compress......, easier to go from belt to spin compressor, less power loss)

In conclusion, this is a supercharger in terms that it will compress the air coming into your intake. It has an advantage over conventional expensive superchargers in that it is cheaper, and electric (so you can if you wish turn it off), but its disadvantages out weigh those advantages... noisy, alot of power loss, takes up space, looks ugly...

so make your own decision, i suggest getting a greddy turbo, even though you still have to deal with turbo lag (the time it takes the engine to produce the exaust to spin the compressor to compress the intake air)

 

well i dont know thats what it said but yeah it looked like a POS

 

This thing doesn't compress air, it pushes it.

 

ive heard of people having those little plastic fins breaking off and going into the intake manifold, and have also read that some people have lost power..wouldnt recommmend

*sigh*
THATS HOW TURBO/SUPER CHARGERS WORK!!!
Pushing something into a space where it dosnt have much room for it (the cylinders) does somethign called...ahem...say it with me now, "C.o.m.p.r.e.s.s.e.s" it.
If you like, ill speak in redneck language so you can understand me.

No... You don't understand.

It increases airflow in your intake.

It's a F-A-N. It doesn't compress anything. It helps to move air.

no, you dont understand...Increasing airflow RAISES COMPRESSION. which is the purpose of a super/turbo charger. they both do the same thing just w/ different powersources. increasing the airflow will put more air in the same amount of space, thus COMPRESSING the air. now, on the otherhand Turbochargers and Superchargers have an advantage on this that in high RPM they maintain the compression, where the compression on this goes down (due to no increase in speed of fan on high RPM b/c the DC power source)

 

Oh jesus... Your compression ratio will not change by installing this thing.

It does not compress at all.

Best case scenario, your engine won't be starving for air.

 

Just so you know, they have things exactly like this, same price, same results, but it's not powered by anything, has no moving parts... It's made to make the air "swirl", which is all this thing does, effectively.

 

I build the pieces of crap.

And I know exactly how superchargers and turbo chargers work.

wow. sounds like you don't like your job.

 

ha it sounds like a hir dryer on speed. best thing ive seen done was driving down the road at like 60 mph or more and holding it out the window to make a siren noise. then chucked into a tree

yes and no
no= it will be starved at higher rpm's cause it restricts it there

 

You would be correct sir, mr know it all doesnt comprehend that in order to move a considerate amount of air, this fan will have to be spinning at about the same speed the turbine in a turbocharger spins at. I dont know what the exact number is, but I will put my life in the line to say this fan DOES NOT spin as fast as a turbo. And the volume of air these "electric superchargers" move into your engine pales in comparison to that of a turbo or a belt driven supercharger. Not to mention, the 20 gauge wires that come with these kits cannot withstand the engine temps and these things are prone to melting and all other sorts of hazardous bullshit. I think it was even proven that these things hinder performance as opposed to helping it, definitely not worth it, and thats not an opinon, thats a fact.

in maggi's defense...actual turbo/superchargers compress the air BEFORE inducing it into the intake mani. ...so you're a bit wrong there, bud.

 

That's why it would be a best case scenario.

yeah. turbo/supercharger turbines spin at about 125,000 RPM or more-ish.

That's where the charger part of super/turbo charger comes from.

1. they acually compress it while they push it into the intake mani, otherwise they would release air in bursts which would be gay (air has to have something to be compressed in) so the compression takes place between the turbine in the turbo/super charger (which wont allow air to go backwards) and the cylinder (before it goes into the cylinder, when the intake valve(s) are closed).

2. This is a supercharger in the sense that it compresses air...now the level at which it does it does not help in performance one bit b/c it moves at a constant rate (which as stated cannot be compared to exaust or belt driven chargers) and it dosnt change its rate w/ moving RPM to maintain that compression rate. Now, it will hinder higher RPM b/c of this.

3. in response to Maginnovision again, the power loss is Greatly significant to that of a normal supercharger due to the stupidity of running it electrically

4. in conclusion, you are wrong b/c it is in a sense a "super charger", though it has absolutely nothing "super" about it

 

This thread reminds me of this....


Are we going to start a debate over an EBAY ELECTRIC SUPERCHARGER? We all know it has no proven performance gains, and they are hunks of ****, end of story. /thread now please.

take the fan off of your computer and put in in your intake tube. SAME THING

 

Please check out Mercedes for their work on electrical superchargers cause theres are good. Everyone do research on blowers, please. Yes this ebay one will increase HP, but if its "worth" it id say no, because ive heard they are noisy, and you know nothing about the credibility of the company, or this things reliability. At WOT at redline, will it increase airflow? Please look into this and get back to us.

 

I'll put it like this.
