The most expensive PC fan ever!

Found this when searching on e-bay, described as a "mini turbo, electric supercharger system"! christ! its looks just like a PC fan in a little silver box to me!

Reduced from £179, they've only got 10 left! tempting [:o)]
Edit = Forgot to put link in!

And it only takes 12 watts!!!!
Woohoo!!!!-I think he's violated every known law of physics and invented perpetual motion into the bargain!!
Let me see,it consumes less power than the courtesy light, yet gives you a 15bhp boost??? I might email him and ask if two put together will give me an extra 30 bhp.......

I am now awaiting his reply.........

He also doesn't appear to know how a turbo works:
"Traditionally cars have enjoyed performance increases via a turbo (re-circulating unburned exhaust gases)"
Which is a complete load of tosh.

Isn't this a supercharger? A mechanically driven supercharger would be more efficient, it would have no electrical losses.
It also says that it will increase efficiency too, not on a petrol engine it won't. More boost means retarded ignition which means less efficiency.

As am I. I asked him if he is aware that he's claiming to have broken the laws of physics!

Lets face it, this does look an itsy bit iffy for that sort of money[8D] But the actual idea of putting some sort of electric fan in the air flow is something I've thought about before. I'm just not sure what sort of volume you'd have to pump in to make a noticeable difference. 179 quids worth?[:(]

OK,
If i may go onto some engineering theory.
Simply the more air you can stuff into an engine the more fuel it can burn and the more power it wil give you.
Piston driven aircraft untilise this very well, at about 300 mph the air being forced through ducting tinto the carb intake can be worth enough extra power to add 50hp.
On a similar note a dyane intake has a cowled intake that forces air into the filter box, thereby basically superchargin it. At the 70 odd mph a dyane can travel at this effect is worth at best maybe 1hp.
Back onto topic this fan unit cannot generate anything like a 70mph wind into your intake so its quite literally not worth a damn.
Anyone who buys one is being conned. But you all know this anyway

Well he hasn't replied yet!!!
Have a look on his website for more info
http://www.powerandeconomy.co.uk/power_booster.html
Theres a picture of one fitted to a golf and lots of brightly coloured graphs.....and while you're there, check out the other stuff!!! Its all patented in Germany after "years of development" by kamann autosport, whoever they are......
"But we cannae defy the laws of physics,captain....." Well they have, Scotty!!!!

If you really want to force air into your inlet ducting, you need something similar to this
http://cgi.ebay.co.uk/Kress-Jets-RK-709 ... dZViewItem
It produces a kilo of static thrust and should produce around 3-4psi in the duct, they are generally efficient to around 200mph airflow velocities, it willbe drawing around 30 amps but this is the sort of thing that stands a chance of making a difference to the engine power,
If anyone wants more details about these engines, let me know and i will dig some more info out, i used to fly electric ducted fan model aircraft and they are very powerful, capable of over 3 kilos of static thrust on some setups and 220mph top speeds (radar trap proven), thats a lot of air being moved !!

i love the following quote....
<blockquote id="quote">quote:<hr height="1" noshade id="quote">cooled air burns more efficiently because their is more oxygen in the air<hr height="1" noshade id="quote"></blockquote id="quote">
wow.... never knew cold air had more oxygen in it....
if only in 1932-1933 when Rolls-Royce was developing their "Merlin" engine for aircraft they had personal computers, they would have relised that their computer fans were more efficient[:o)][:o)][:o)]
imagine fitting this,

to this [:D][:0][:o)]

which was eventually developed to be a beast of a (about)27litre 2000HP [:D]

Apparently the supercharger on a Merlin needs 400bhp to run it, that's a bit more than 12 watts.

I did a search on the website for "Bullsh*t" but it said no matching items were found.
Must be genuine then.[:p]

demag · Post by **demag** » 25 Aug 2005, 04:22

Reading all of this has somehow reminded me of something that happened many many years ago. But being as this thread is quite interesting I wouldn't dare hijack it. I'll start a new one, "Water Injection" [:)]

That second question did make me chuckle!!!!
