right guys before i start i have not considered this but came across it when looking into a cold air scoop system and thought it would be something to talk about. so dont rip me, comment on the product :thumbsup:

so the real superchargers that are on offer for the zeds cost thousands of pounds and give great increases,ELECTRIC WILL NEVER COMPARE:

http://www.electricsupercharger.com/products.html

right they don't offer much gains. say 5 hp and 10 torque but for £ 200 it ain't bad and coupled with a ram air scoop it might get a few more. the second reason this got my attention is the fact it can easily be removed within minutes. now ive read some posts on other forums and everyone says their crap but these ppl dont have them and will never have seen one so have no idea what they are talking about :x and the few that have got them were quite happy with what they got from what i read.

now i guess there might be other suppliers who offer better kit but this system seems to be the most well known
 
God, put these on a roadster and the tin-tops will insist its the obligatory hairdryer :roll:
 
Strikes me that if it were this easy, then every car would have a hairdryer on the inlet manifold as standard.

Just a guess but I'd imagine that the induction from the engine is far more powerful than this, so making this mod. an excuse for insurance companies not to pay out in the event of an accident.... :roll:
 
The motor is no way near powerful enough to generate any extra power from forced induction, I would stay well clear and save you £200 for other Z4 mods.

Yup, looking at it there's what, £3 for a 12v computer fan, £5 at most for a bit of fancy ducting and a few jubilee clips, so £10 invested here maximum.
I mean you'd think they'd at least throw in a whizzy sticker screaming 'Suuuuuper-charged powah!' so you could feel your £200... :wink:

If It could move enough air I don't see why it wouldn't work...... It would need to be powerful tho, I see positive boost at like 1k rpm
 
Just realised they are in the good old US of A where Trading Standards is probably something you do on Wall St...

Total snake oil IMHO.

As AndrewR says, it would need something seriously meaty to drive enough ADDITIONAL airflow into the engine at any sort of speed. Otherwise it creates more obstruction than it overcomes......

Just email them and ask to see their independently certified technical reports and evaluation before spending actual money.

But Georgio's idea for a sticker has got me going (reminds me of the infamous "Drums of Powah"on a certain website.....maybe I could sell a few to forum members if I had them made up? :rofl:
 
What does "Up to 27 more horsepower GUARANTEED!" mean. ?

That sentence doesn't seem to make sense.

An electric supercharger was discussed and ridiculed on another forum but not sure if its the same product.

The larger one looks like a Vaillant flu joined with gaffer tape.
 
a supercharger and a turbo are just fans at the end of the day so there is no reason it cant work in logic. hell a turbo runs of gas and that does the job. dont think the 12v battery ones would do much but the higher rated ones running from a few lithium ion battery packs must be able to do something. could have it set as a bypass and have a go fast switch :D

what about this http://www.youtube.com/watch?v=TPxfGKhXpDM
 
Yea except that a real turbo runs in excess 100k and 20psi pressure, that sort of makes that moot. The bottom line is that any device like this will not benefit the engine one iota unless it is positively forcing air into the cylinders and trust me, in this case the suction from the pistons more than blows this out of the water. :wink:
Regarding the Skyline video, unless you see the tests run back to back disabled/enabled (which you don't) those graphs are meaningless.
I did lol though as that looked more like a hair dryer than a hair dryer... :roll:

Back in the Eighties, I used to work for a small car accessory manufacturer and part of my job was dreaming up crap that people would pay money for to bolt/stick to their gleaming cars.
My all time best selling item was a little black box that sat on the rear parcel shelf with a microswitch running to the gas pedal that lit up with 'TURBO' everytime the pedal was pushed past a certain point.
It was actually conceived as a piss-take as I was fed up with all my good ideas being shelved by management.
God knows where all the units ended up as thankfully I've never seen one used in anger; I think I'd wet myself laughing. :D

think this is the only true system available and it can only work in short bursts due to the power requirements. said that its currently being tested on hybrid prototypes combined with a turbo to give low end power until the turbo kicks in
 
Surely you would still need to remap your ECU to take advantage of the increased force induction (supposing there is any increase). Without a remap, the engine wouldn't supply enough fuel for you to benefit from any increase in air flow.

Persaktly.

A supercharger is mechanically driven and therefore has all the torque it needs to provide the requisite increase in airflow - this POS cannot possibly deliver that kind of performance without something the size and weight of a starter motor inside it.....
 
The web page states that 5% gain is valid for engines with over 300bhp or more than 5.0 litre capacity.

Just having a think about. Provided that it doesn't cause any restrictions, at 1.7psi the gains on a 3.0i zed could be roughly 10bhp. However, you'd need to ensure no heat soak. It's an awful lot of cash for a gain that's not guaranteed.

For just a little more you could probably get your ECU remapped - which you would probably need for this anyway, and be likely to get your car closer to the stated manufacturer BHP in doing so (again with ECU remaps, I reckon you might restore factory BHP but am dubious if you would see a real gain).

If you do get one, would be good to hear your experience with it, bad or good
