do these work??? i wouldnt have personally thought that this sort of thing would work... but then again, if it is powerful enough why wouldnt it???

CONFUSED!!!

what do you guys think???

[phurn]

They work.... my understanding is that its just an electric motor that pressurizes the air intake.

[MarkyB]

If they work why don't they at least have a video of a car on a rolling road with and without one, to show what they can do?

[phurn]

They do work, several companies make them. Much less effective than belt driven, but no mechanical drag. They're nothin new, even if they are unusual.

[rayofleamington]

They work if they are correctly engineered. The ones that the big car companies are looking at for 500+ HP are serious bits of kit.

Some of the stuff found on ebay is however very questionable... ;-) To provide enough air flow & pressure for an engine at max rpm is not something a small wattage fan will achieve.

About as effective as rigging your heater blower up to the carb intake- i.e. they do not work, certainly the cheaper ones.

[phurn]

very true! id avoid cheap tat... but then thats hardly advice unique to super chargers. and from my understanding it wouldnt work on an a series as it needs a car with efi to function properly. it also needs a massive, massive alternator for its acumulators as a half decent one woudl consume something in the region of 900 amps!!

[phurn]

and ofcourse, theyre VERY inefficient, i mean when you think about the amount of times your moving power around on that system... the losses are gonna be incredible!

so they DO work... but do they work well enough to be worth the fuss? well thats debatable.

a quick bit of maths would see a 500bhp boost be a very serious bit of kit indeed!!!!!
500bhp = 373kw (roughly)
373kw = 12*I
I = 373kw/12
I = 31083.333A

3kA !!!!!!!!!!!!!!!! unless ive gone hideously wrong somewhere? thats a rediculous amount of current.

[chrisryder]

actually you have gone hideously wrong, 31083.333A is 31kA, not 3kA!

Picturing that made me chuckle

The one in the youtube vid also looks worryingly like a hair dryer from the 1940s...

[phurn]

Haha trust me to f**k the easy bit up =[ eitherway I saw a test of one online and it added 7bhp..... so they do work.... but why bother.

[rossrox]

what sort of car was that though???
obviously on a smaller engine it would be better than say a v6 or v12,
if only some one did a money back guarentee, i would try it then. if it was effecient with power it would be a pretty good upgrade i imagine.

[phurn]

Max power theorem means it can't be that efficient. It was an old 1.3 golf I beleive.....
