Hi guys,
Stumbled upon these 2 items for US' DIamante... Wonder if they are really useful and cheaper than changing engine... The 2 postings seem to claim that they are effective in boosting the power with better fuel consumption at the same time...

Comments please... :)
Thanks

seen those electronic supercharger before. NOt sure if theyre any good or not but its a nice idea. AS for that "CHIP" which remaps the ecu, thats so full of bs i dont know where to start. its like those ones they were selling before which was basically a resistor in the MAF sensor which otld the ECU less air was flowwing than actually was and hence the engine ran slightly lean. Does get more power but not in a healthy way. not bad really hey, $25 for a resistor :nuts:

The chip is BS just makes the car run lean which isn't cool. The electronic "supercharger" although it really should be called an electronic "turbocharger" sounds like it COULD work, as long as the electric fan spun quick enough to pull in the air alot faster. I can see how it CAN work, as long as it can pull air in faster than the TB than it'll provide SOME boost, how much would probably be VERY minimal. It's basically doing what a turbo does only its using battery power to spin the fan/turbine instead of exhaust gases.

The Electric fan idea got picked apart on one of the other forums. Basically the air required by the engine is substantially more than an electric fan can supply so the fan adds nothing

Hubcaps that actually swirl the air around your tyres so you get less wind resistance :bowrofl:

Maybe placing the electric turbo; pre-filter, for example: on a cai hose leading to the filter.
But would probably only be good for 1-3kw.

Assuming the electric turbo could pull in air faster than the stock vacumm, you'd get a power gain. Depending on how quick it could pull air in faster would determine boost, but i highly doubt that it could pull air in much faster, if faster at all.

It cant, hence why it becomes a disruption in air flow

i saw on drivetime tv - they had a segment on superchargers. they said that the electric superchargers are ok for a small increase in power - but are no where compared to the normal belt driven superchargers

if an electric supercharger were able to be powerful enough to force air in at enough pressure to make a difference, keep in mind it needs to draw power from the engine make it work.
Id say your probably gonna be losing power because its restricting air flow like killbilly and tr-envy said. And its gonna be using the engines power.
Much like losing power when your air-con is on.
if you didnt understand what i said cause its late and i dunno what im saying.
this electric sc will be no good.
if it were any good, and cheap. car manufacturers would be using them.

I wasn't thinking of it in use as a forced induction setup. Just more of a pump for the cai. It might come in handy at low speeds; where the cai doesn't get as much air forced in naturally.

Handy at low low revs and idle, possibly, but once you start booting it, it then becomes an obstruction. Overall it wont be worth it

Then the only way to overcome this obstruction would be variable intake pipes. Would that work?

So you're saying have a fan bypass pipe? I guess that'd work. The SOHC 12v and DOHC 24v already have VICS (Variable Intake Control System) in the intake plenum itself. This lets the air travel longer at lower revs for more low torque and then it changes to let the air travel shorter distance for more high torque.
I suppose a system like that again would work. But I don't really think it'd be worth the effort...

I looked into it a little and here is what I reckon...
In big motors eg. 2.6L, 3.0L etc the motors consume too much air and as someone stated before that it would be helpful at low rpm where the motor is not drawing so much air. My most generous guest is that this device will only maintain a steady 1 atmosphere (no boost - no vacuum) pressure into the engine at high rpm. When cars are near the redline the motor cannot suck air in fast enough and they start to pull a little vacuum. This would prevent this from happening. My best guess is that it would have the same power advantage as fitting a high flow air filter. Combine the two together to get the most out of it.
Now here is where it relly works...
1 Litre motors!!!
Strap it onto a 1 litre eg. Charade or something (sorry dude just an example :) ) A small motor like that would never pull more air than the electric turbo will push out, therefore boosting not much mind you but it would be over the whole rev range.
NOW, this is where it gets good
Its called electric turbo-ing your motorbike!!! You might have seen on the internet some turbocharged Suzuki R1's (Hayabusa's) getting around. They cost alot apparently. Especially fitted with a turbocharger.
So an even smaller motor eg. 600cc - 800cc with an E/Turbo fitted on to it would be quite beneficial me thinks. Even though they can rev alot more, in theory it would maintain pressure to the motor through the whole rev range.
BTW you would want a kickdown switch to turn it on under full load otherwise it would put a load on the alternator and sort of checkmate its purpose when you are just putting along.
That is all. I want to E/Turbo my lawnmower that would be mad NOT

really should be called an electronic "turbocharger"
turbocharger is a type of supercharger but a supercharger isn't a type of turbocharger
if you get what i mean :P

...or get an aftermarket alternator.
Your research raises a few more q's, what about twin e-turbo'ing?

do a search on these forums, they have been discussed before, you are better off getting a petrol leaf blower and attaching this, would work about the same lol

for a supercharger requires 5kw of power to provide enough compressed air to make an engine produce an aditional 50 kw of power. Now tell me where that tiny little thing has an electric motor capable of making 5kw of power?? isactly. These are both big fat scams

OOh I have one of them!!!
Imagine having to start the car, getting out..and then having to pull the cord as well hahahahah

Even if it did have a strong enough electric motor, them thin wires on it would never be able to handle the current that thing would need.

I like the way _x_Firesotrm_x_ thinks. Twins E/Turbo's. I would think that if volume of air is the issue, then I would not suggest twin sequential (one mounted after the other) E/Turbo's, eg. Toyota Soarer/Supra, but I would think having the two E/Turbos mounted in parallel (side by side) eg. Nissan 300ZX tt. They would be able to deliver subsantially more volume of air with them working together.
I'll do a good diagram when I get home.
And IMHO Power gains from this set up would not be anything fantastic, but it would be cheap and to some degree - effective
IMHO: In my humble opinion

How about QUAD E/Turbos running off a seperate battery to avoid any drop in voltage? I know i wont be doing it but it sounds interesting lol .

you would need a seriously big alternator for that kind of thing. i think twin would be the most practicle.
