Is this a gimmic?
« on: October 06, 2007, 19:42:07 »
Saw this on ebay and wondered if it would make any performance or is it just a waste of money?

If it's anything like the ones I've seen before, it's basically a £5 PC cooling fan in a fancy package.  The only difference it will make to your truck is that your brain will tell you that because it's cost £140 the truck MUST be going faster.

However, if they HAVE actually managed to produce a small electric fan which can force similar amounts of air in as the considerable power of a mechanical supercharger, then I'll stand corrected.  But I doubt it.

snake oil, they are clearly trying for the muppet /boy racer market. there is no way a crappy little electric fan on 8 amp wire can make any difference. Turbos pressurise the charge this wont....utter BULL

A typical car alternator can develope in the region of 0.75KW of power.

Not found an acurate figure but from numbers I've heard quoted a typical supercharger will consume 5% of the engine power to work. So say superchaged car generating 200hp (apporx 150KW) would require 7.5KW of power or 10 times the output of the alternator to run the supercharger :roll:

There is one that REALLY works.

Its 2 starters attached to a roots supercharger and uses 2 truck batteries in the boot!


These are just garbage. I've had something working on smaller engines, but think of how much a 110cc engine produces in KW and we were using a 1.3Kw leaf blower.

Load of rubbish, it's not even got the right internal body shape for the job. Probably find any increase in performance is from the filter (if the fan doesn't restrict airflow)  and in the mind.

looks more likely to reduce the amount of air intake because of the restriction it causes then the fan could add. tThe fan is design to move not really produce any pressure

the graphs don't actually say what the other line is ..

"the black line is with the thing fitted"...  it doesn't actually say the red line is without it fitted, that could just be where a drunken ant widdled on the graph paper :D

Hadn't noticed the graph, I was laughing too hard by that point.  It's probably the power achieved with the engine switched off or something.

You can get a power gain by routing the air intake to the bottom of the bumper where the air is colder, but don't drive through any puddles :lol:

Do you reckon that the picture of the flames out the back of the car is produced when the Fan collapse's and goes through the induction system and cause's the engine to self distruct?? :lol:  :lol:  :lol:

Mabey but the idea of an electric supercharger is half right (the supercharger part)



Or If your greedy just have both turbo and supercharger bolted to a 1.8 liter engine to produce upwards of 470hp (claimed 600hp) :twisted: Its all in their somewhere

These DO work :



Note the difference in engineering (and price)
