hey gus theres work on a electronic supercharger...
that dilivers 3-6 psi...

whats the go/ word
its cheap and usless bita fun if u dun want to upgrade ny enginparts :D verry simple to install aswell i here..

whjat does every one think?

To good to be true me thinks. And i doubt it will be cheap...

If its good i want one :D

i'll take one of them aswell
where do i sign up ?

Where did you hear this?

hehe its probably just a fan attached to the intake or something :)

Yeah - I would be keeping away from it - I think electric S/C's have ben around for about 5 yrs - and no-one is keen to bolt on up!!

Manual

wouldn't you need a fair bit of power to run the electric motor to spin out 3-6 psi?. And didn't holden toy around with this idea years back?

it sounds like a good idea but could be tricky to do well.... power via electricity has very low loss so the power needed to drive a electric motor (with a blower attached) would most likely be more efficient than a belt driven one...
(hang on, no it wouldnt as there would need to be a belt driving the generator, doh, its already there, its called an alternator (slaps self in forehead) , doh, dont mind me... ](*,) ](*,) back to the story)

so if you got a decent motor (that didnt drain to much of the power returning to the battery) and hooked a blower to it there is no reason why such a beast wouldn't work!

we all know that normal super chargers take power to run anyway so having an electrical arrangement would be more efficient, the trick would be finding a motor that would have the torque spread across the rev range required for a direct drive to the blower! Unless you just had it running at maximum all the time! sounds like antilag turbo to me!

(hmm i wonder if they'ld let me do one of these for my final year project??)

hey gus theres work on a electronic supercharger... It's other feature's include an electronic Blow Me Valve and some fancy coloured stickers. it should add 200 horse power at the wheels



Widowmaker Quitely walks back out of room and pretends he never heard a Magna owner say such things

:badgrin: :lol: 8)

HAHA :lol:
you funny.. Widow :D

AFAIK these sit in the air intake.

The fan spins good at low rpm

But in high rpm the fan can't spin faster than the inflow of air and thus becomes and obstruction.

Also the MAS sensor cant have turbulent air.

If it's not one of those things then disregard my post

It's proberbly the same as those electronic zet turbochargers. Basically the reviews i've been say its a pc fan forcing air into the intake, and basically a waste of $500. They even made the twin turbo electronic zet.

Steer clear of this methinx. If it was effective/cheap and actually worked I think everyone would have heard of it - and have one :)

yeah i agree.... if its a piddly little 12v fan (out of a PC even) blowing air in, i would not even piss on it if there was a fire!!! it would need to be a elec motor hooked to a forced system akin to a turbo or supercharger thus providing a decent pressure difference!

You can get an elec turbo that works quite well so i dont see why this would be so different and useless

just a thought :?

There is one that works - it uses a proper turbocharger impellor and compressor housing, and a great big mofo of a motor using 4GA power cables - heatsoak is extreme in the motor, so it can only be used for short lengths of time.

That said, I once experimented with a blower fan out of a wreck (ie. heater dash fan) on an EFI car, put in about 0.5 psi (yeah woohoo) into the intake. Weird thing was it made a difference - was on an old pulsar, which was MAP sensed though... and a small engine.

Oh yeah additionally, I was thinking of using an old turbocharger I have in the shed off the saab with the motor out of an angle grinder (for RPM) hooked up to an inverter... hmmmm....

Cheers
Heath Young

that sounds like an interesting idea, just remember that you have to make sure the angle grinder motor doesn't spin to fast, i.e spins the turbo past it's efficiency limit(spins too fast creating very hot air and drops off effective boost) But then again turbos do spin very fast ;) . I recon give it a go, you got me thinking now, but I don't have spare turbos lying around :shock:

my first post...

The real advantage of a proper electronic supercharger is having full boost off idle... It can be hooked up to the cabin, and set electronically to pre adjust its fan speed to set rpm's etc. The device is cased at the front intake, possibly ocscuring air from entering into the engine.

My thoughts- these days so much has been done with engines, saab has mad a 'Variable Compression engine" (cool) which has forced induction capable of delivering 40psi... Obviously an electric supercharger could be developed... properly. Simply adjusting to the engine rpm to allow maximum power to develop, when ever.

Ive read in a book called "21st Century Performance" By Julian Edgar, he reckons that electronic sc's are a waste of time because the alternator would have to run all the time, i guess he felt the crappy efficiency of such a device would out-weigh its benefits. :oops:

P.S- Imagine what would happen to the torque curve jst after idle, maybe a huge lump >1000rpm?

:D

how long deos the magna MAS sensor take to adjust to new airflows?
- If the airflow varies all the time, wouldn't the ecu get confused???

or

is it maped out, like every 125rpm, then changed accordingly?

crazedmitsuboy: I agree with what the guy said in that book, but what if you ran 2 alternators?

whats the difference between an electric sc and a regular sc?

wouldnt you be better off with the power for the sc coming direct from the engine in some form of DYNO? that way you have power as soon as the engine turns over, and if you get one with a clutch, you can have a nice button on your steering wheel to switch it on and off, which i was under the impression is perfectly legal (on vic p's)

Cripes, a angle grinder and spare turbo,,,,,(me looks at grinder) :idea:

I think from memory most grinders run about 2000rpm to 3500rpm, cause the disc's cant handle anymore than that, but turbo's run upto 40,000rpm, so I dont think it would work too well at such low rpm?

And imagine the noise under the bonnet!!! :shock:

dremels can run at 10,000rpm which is nearly what turbo's run at .... but how long a dremel can run at that speed is questionable

Have a close look at the rpm on a grinder - I have one here that has on the motor info plate 18,000 RPM - they are geared down, so you would have to bolt the turbine to the motor shaft somehow.

I have a spare turbo if anyone wants to try :o)

Well if they are geared down then your problem is half solved, but as widowmaker said I think they would'nt last too long, there not meant for such a task, I reckon the grinder would be dead in about a months time tops.

I think someone mentioned something about a fan, that has me thinking, even if you got a small amount of pressure it would help but also if that air was colder and coming from an outside source and the whole lot was inclosed of course I think it would be easy enough to fabricate and impliment. I am thinking the fan unit could be hooked up to the accelerator cable thing on the throttle body with a resistor switch of some sort to increase the fan speed with acceleration therefore not running the fan at a constant speed at low rpm but increasing it with the rpm.
I probably made boo boo's in that statement so someone will correct me I am sure. ;)

If you want to use a Makita or a DeWalt grinder then you should get a decent amount of life out of it. Coz they're TOUGH.

Oh you could possibly hook it up to a switch in the car? Maybe so it's not on all the time?

I dunno..just dreamin..lol

I came accross a site a couple years back, that some guys made, It had info on some funny ass modification they did, the one that really cracked me up was, that they hooked up a weed blower(petrol powered) to the intake of a 240Z(olskool) and it was held in place by some rope and duct tape :lol: .When testing the 0-100 times, from memory they nocked off about 0.2secs off the original time. :roll:
