Supercharger intake fan?

Geno325is · #1 (**permalink**) 05-02-2002, 08:16 AM

I ran across this on Ebay, http://cgi.ebay.com/ebaymotors/ws/eb...727610&r=0&t=0

Has anyone tried it or know anybody that has one installed?

Heres another one with an internal Fan http://cgi.ebay.com/ebaymotors/ws/eB...tem=1825936066 Is this a ripoff?

it's a scam. don't waste your money. calling it a supercharger is a joke.

If your going to get Electric supercharger the Only good one is Eram ( www.electricsupercharger.com )

BTW- its not a scam, it really does work, dont talk crap about something you havent even tried.

Well in general E-ram Dont work that well. Turbodyne made some heavy duty decently large electric suspercharges that still did not turn enough to produce noticeable results. They are used on turbo desiel busses to get a little more kick at low rpm, but on normal cars (gas) and the intake air's veloicty, it doesn't help much. A kid here designed and built an electric supercharger that spun twice as fast as the e-ram (his spun at 80000 i believe) and the calculated speed to produce any more velocity that the engine needed was something like 110000. But anyways, if you have dynoed proof thats a CONTROLLED dyno, as in you have a BASE STOCK engine dyno, thats consistent avg, and you have a dyno with ERAM ONLY, nothing else, and it says you improved, than thats cool, but in general it was a lousy design that needs much refining. Butt dyno is not sufficient for good proof, haha.

Yes it produces gains, obviously your a pesimist. Its not just the RPM of the fan. Shape of fan, diameter and everything play a big part. Oh by the way someone with Eram at bimmer forums go 16 HP DYNOED, so theres your proof, it work, sorry but your wrong.

I know of one guy that dynoed and got 16+, but it wasn't controlled at all. Different weather, different dyno, and he did other mods at the same time. Where is this dyno, and who is it, i would lke to speak to him and find out some stuff. And you should just read my reply a little further maybe you missed some sentences. But ask most people who are engineers, and who know about them, how they work, and how to make one that does work, the eram was not a good design as far as optimum power goes. And its certainely not cheap at $300+

If you have proof show it, but from experience, and seeing my friends design, which would theroetically produce more then twice the flow (psi) as the eram, and even it did not work well enough, I think the eram produces HALF a PSI, and I dont know about your physics, but look at your normal flow, and half a PSI, considering it only runs at Wide open throttle, unless the engine was seriously deprived and resticted of air before it should not privde more then maybe 2 hp. I know someone at caltech who has one, and he swore it work, but could not get dyno evidence, he now has a 275whp VR6 with a custom h20/methonal injection he deisgned, which gave him 40whp! So thats the only real reason... But hes the only one out of maybe 30 people I have spoken to who had it before selling it on ebay to a civic owner...

i don't need to smoke crack to know it's a bad idea.

what i do know:
1. i would not buy anything from someone who writes this in their ad: "Many hace these already and are completely." informative and convincing.
2. i worked in the automotive industry for 7 years. i have seen just about everything you can imagine. people who advertise 20hp gains for an air filter, 20hp for a chip, and 20hp for an exhuast (on a stock na engine) are lying.
3. if this product worked, our regular aftermarket suppliers would be selling it to us and we would be hearing testimonials about how great it is.
4. the guy posting this ad has not bothered to proofread his ad, let alone post dyno charts or support his claims in any way.
5. people have been working on electric superchargers and hybrid superchargers for a long time. those people would not want to be associated with this dumb*ss on e-bay who is selling a computer fan that fits in your intake. this guy on e-bay is scamming people, plain and simple.

i don't know if you have some kind of connection with this guy on e-bay or what your deal is, but i would really like to see you buy that piece of crap and put it on your engine. get real.

TRue dat!

supabimma · #10 (**permalink**) 05-02-2002, 08:03 PM

hey man, whatever helps you go to sleep at night, believe it. but you havent tried it so your opinion means absolutely nothing. thats the bottom line.

LITEWAITM3 · #11 (**permalink**) 05-02-2002, 08:12 PM

Do you have it?

i sleep better when i don't give my money away.
by all means, buy it and dyno it. if you are so willing to stand up for this product don't you think you should get it? are you the one selling it?

supabimma · #13 (**permalink**) 05-02-2002, 08:27 PM

Of course i have the Eram, why else would we be having this discussion. I have AA chip, AA gen 3 exhaust, and an intake and i can honestly say the Eram helped out the most. I honestly believe it helps ALOT. but people out there always bash me for it, oh well. everyone who has one likes it.

I am not selling those ghetto computer fans fake E-SC off ebayn (i would never sell mine), the only one i would trust is Eram, powerdyne and those others look like crap.

anyways just my 2 cents

didn't you accuse me of "talking crap" when i said the one on e-bay was a scam? but now you are calling it a ghetto computer fan? i hope you don't drive like you argue, because you are all over the place.

Your car is also on an Auto... harder to feel true gains with it.

But if you have ever studied any engineering, and the physics behyind it, at 1psi, it would need to have incredibly designed flow characteristics/properties. They basicly took a very high speed, high-powered, electronically commutated electric motors, and stuck it in a tube. It only makes ONE PSI! The turbodyne turbopac and turbocharger can be made to get to 5.5psi+, thats close to a normal supercharger without anylose from extra power it takes to push the supercharger, which is normally 30% taken to power the normal supercharger, so it would have to make enough power to make that 30% up plus. And since those s/c are at say 8psi, think about what one psi would do, not much, if anything at all. Its a good idea, but the e-ram was not designed as well as some others. Maybe for $300 you might feel its worth it, considering the real electric suspercharger are close to $1000, but provide much greater gains, close to some stage I normal superchargers.
Just to clarify the motor type is an axial compressor Brushless dc motor...

And the ebay sellers description says, "besides the added advantage of forcing more cold air into the motor it also adds motion to the air making sure the maximum amount of air enters your cars intake." Now thats engineering technology at its finest! haha
