Electric Intake? Is This Just Crap?

[dcanna]

has anyone ever heard of this thing

My Webpage

[johan.p.g]

if ur talkin about an electronic supercharger all it is is an electric fan that removes any negative pressure in the intake manifold and is apparently not as effective as they say although it will make some difference

its absolute rubbish, dont buy any sort of "power intake" or "power increaser" or "power chip" thing from ebay...

they theoretically sound good... but are far far from it

[fr0st]

There not even theoretically sound.

These things use a motor that has about 90% efficiency. Charging you battery is ~60% efficient (?). On top of that the alternator is 80-90% efficient and it takes power from the motor to start with. I'm just pulling numbers out of my ass but you get the idea.

ja matt i see your point, but this is when you start looking into practically... and the whole theoretically sound thing too deeply

they are "theoretically sound" as in that they are attempting (and quite badly i might add) to force more air into the intake...

they are theoretically sound otherwise idiots wouldnt be buying them would they?

we all on the same wavelength though.

1000 CFM at 2psi.

fairly restrictive warranty.

I could see it helping - if you have a 1.6L N/A econobox. A little more torque off the mark.

maybe it would help on a 1.8.... how much air does your engine suck at 2krpm? 3? 7?

waste of time on an engine that develops any sort of decent power, and as soon as you are moving, well, there is that extra load. don't forget electrical load is turned into mechanical resistence in the altenator.

Not saying I wouldn't buy one - I just don't happen to have an EFI 1.6 shopping trolley.

EDIT: spelling

I was reading an article on the popular science website where they tested a whole bunch of 'fuel saving' devices and they conluded that the best you can hope for is nothing will happen, one device even set the car on fire most just increased fuel consumption and decreased power.

i made one which worked... got 0.2 psi

literatly.. it worked..

hahahahahahaha if they were such a rip off i'd do the tests on a dyno on my daily shitta

Car catches fire, you stop driving it. You stop driving it, the engine stops burning fuel.

System works as advertised. No refunds.

haha, i have been meaning to look into these heard a bit about them iv seen 1 in someones engine b4 not much i know about them. apart from what u guys already know.

[blackprincegts]

guy at my work has one on a paseo 1.5. He said it definately does give more grunt but the fuel consumtion DID NOT get better, it got allot worse according to him. Apparently theres simlilar systems for motor bikes that iv heard some people rave about.but thats on a very small motor remember

my opinion on them is that they probably would add maybe 4 ish kw's of power at the wheels on a small motor NA car.Youd be able to only just feel the difference i rekn. I guess if your modding a small capacity NA with cheap bolt on uprgades for a little extra get up and go then it would be ok. On there website they do say that they " work best on smaller engines".
