have anyone of you guys ever come across this?
i found it while looking for info on my new project of supercharging my z.
i went through their sight and rmembered seeing their product at a sema show it does look halfway legit from what i see

please dont just call me stupid and claim it doesnt work before reading through their sight

http://www.electricsupercharger.com

i found the read quiet enterting and somewhat believeable.

let me know what you guys think

 

this has been discussed on here before. what does it claim? 4 lbs.? i wouldn't do it. it would throw off the MAF i bet.

 

no this specific one hasent which is why i brought it up
it "claims" 1.7psi at the manifold gaurenteed
which is alot for a bolt on producton a n/a motor with the compression ratio it has compared to the tt

 

ok i stand corrected i found the other thread on this.
but i think there more taking about the cheap 35 dollar ones
i have seen this blower personally and it really does blow a tremoundous 900cfm (i believe it was that or in that range).

 

its a sham! let it die. and theres been PLENTY of threads on this its crazy. also i cant read through there SIGHT. and i didn't know a thread could be QUIET interesting.



im just givin yah **** but those typo's are damn funny. and kinda bad. engineering student you say?


also as a student becoming a pilot we have to study airplane mechanics as well, and being a car enthusiast i can easily piece together how this could NEVER work the way they have it set up. all they have is a fan in the intake it might be able to flow that much air but think of the vacuum your engine makes as well as how a turbo/supercharger works. it uses COMPRESSED air. unless its a roots based super charger known as a blower then it blows air and a rate compressing it in the intake system which could be similar to this but nope... the roots is a vein based tube so air can only go one way on it completely air tight but can pass air when spinning but only one direction. this is just a fan blade it could never hold pressure not ever if it could flow enough air to actually beat the vacuum in an engine it wouldn't matter it would just do a primitive style compressor surge where the induction air being pressurized leaks backwards past the blades that created the pressure in the first place. airplane turbine engines defeated this with 1st and 2nd stage fan and compressor blades which basically create a check fan for the previous so the pressurized air cannot leak backwards since it has the back up, NORMALLY! sometimes even airplane turbine engines can experience compressor surge themselves which is loud as **** and can be very bad. thats why this e charger could possibly work with a crazy electronic setup for the power it needs and a series of compressor fans not just one of them.

 

what did that thread say? i don't even remember. i just remember that it was heavily bashed. ahhhhhhh. i guess i'll look it up

 

Wait... in the 10+ years that this electric supercharger has been produced, we've actually talked about it? It's still around because there's still suckers willing to buy it.

 

yeah like i said i found the product to be very interesting and it has the potential to work i get bored at work and look random **** up and came across this. and yes i see what you mean by the jet turbine engines it was a good point to bring it up as it is very simmilar in the concept. i wonder though is how it would do if you miultistaged them but im not going to buy them and find out. im just going to fab up a real supercharger for my z

 

better choice ^^^^ not the best but better. and if you go through with this project it will be very interesting to see. if i were to create one and had crazy fab skills id use a VERY large brushless outrunner motor because they create more torque best electric motor design out there and there could be no gear reduction because you will need all the RPMS from that thing to spin up and then real compressor styled metal blades in a series at least 5 rows of them. but even then the thing will need a heat sink or it will burn up take up alot of room be noisy need to have a speed controller synched to the TPS somehow. it will be VERY expensive and probably just as much as it would cost to just do it the right way. also the motor will probably burn out fairly quickly and need more maintenance than a conventional setup

 

a couple people have tried sticking leaf blowers in the intake of honda civics and have gotten good results. +40 hp but that's WAY more than 1.7psi. I don't think on a Turbo or N/A it would make a huge difference, perhaps 10 hp on the low end but it would quickly decrease as the RPM went up.





I apologize about the music ahead of time.

saw that before, i also saw something i thought might almost be pure genius. but i doubt the electric motor can spin this thing fast enough without gearing

http://www.youtube.com/watch?v=UolyXuUAJWU

 

I blame that video on snw.

 

so the electric superchargers, all the ones iv seen like this are gay looking but, a while back my buddy showed me one for sale, looked legit, mainly cuz it was a huge electric motor mounted to blower required an extra car battery and could only be used for XX amount of seconds, like twenty sec or something, anyone seen this? ill serch more for it
this sounds more reasonable and is used more like nos
its something like this

^^^ That setup makes no sense... Why would they put a BOV between the air filter & ESC? Or... if that is the positive pressure side... why would there be a huge cone filter to let the pressure escape before hitting the motor? And 3 starters making 7000RPM... Yeah... right. And 7000RPM would still be too low to produce any boost.

 

Read my words - ELECTRIC "SUPERCHARGERS" DO NOT WORK.

[/thread]

 

im going to buy one and prove u wrong.lol jk screw that. all im saying is its possible. these words do not say that this one works lol but its possible. and the inline fan that is probably like a comp cooling fan holy hell lol if u put that in with a tornado, especially on a fuel injected model. that would be like 175 extra horseys lol, and 75 mpg. btw did a tornado on a carb make any difference at all?like provin on the dyno any?????? sorry for updating this, dont think im trying to argue the 75 dollar el super charger deal lol

what kind of cfm is a 2.8L (280zx n/a) moving at like 4000rpms? any guesses???

 

No guesses, but some turbos spin at up to 250,000rpms (most are easily over 100,000rpms)... it's gonna take one HELL of an electric motor to mimic that (not likely one that'll fit in the engine bay easily with modern technology).

 

its possible witha very strong motor and proper gearing like in a supercharger because they only use engine speed which means 7k rotation tops on most cars but they make full boost pretty down low as well.

 

Superchargers spin at 30,000 to 65,000rpm... and they have the torque of the motor to keep them spinning. It'd still be one hell of an electric motor to have it spin 30,000rpms with a fan capable of forcing air into an engine (there's obviously more to this than the RPMs the motor can achieve - there's also the resistance the motor will encounter from trying to compress air).

 

obviously... also a motor that large spinning that hard such as a starter motor will probably have over heating problems. im just stating, theoretically, its possible. its just not worth it

 

ok i can get boast off a lil electric leaf blower on my sand rail i know cuz iv done it for ***** and giggles (vdub bug motor) just never had nearly big enough urge to get rid of the cord, and ur gonna sit there and tell me that u dont think u can get a spare battery and a big enough power converter to handle a leaf blower?????? please. i think the thing to argue is trying to run one constantly instead of like the knightly charger which is like nos the chargers cant run very long before it has to recharge and cool

and to your super charger rpms.. the super charger on my olds is boasting at easily at 3500 rpm's comparing crankshaft pulley diameter to super charger pulley diameter just guessing from looking at it and taking pie into consideration id say the super pulley is traveling 2 times as fast as crank pulley, so its boosting at 7000 rpms on the super pulley, redline on motor is close to six if i remember right and who knows how low of rpm it actually turns pos on boost, r u saying my stock olds supercharger has reduction gears in it???? or does snw sound pretty accurate in his guess^^^^^^^^??????

 

anyone understand a damn thing he just said ^^^ cuase it sounded kinda like a constant spew of **** from his keyboard, maybe its just me though....

 

my question for this is.. it shows what 1.5 pounds or so at the intake manifold? i assume when idleing or off?
well what happends when the engine is running..
you floor it, the engine is sucking 3x the air it would at idle.
the little fan cant keep up and it just is something blocking air flow.
the only way i see this working would be alot bigger electric engine thats capable of 20,000+ RPM (with the impeller on) and some sort of diode to control the RPM as the engine advances RPM. a supercharger advances RPM via the pully on the engine, and a turbo advances RPM via exhaust gas running through the turbine, faster the engine RPM the more gas coming out, the faster the turbine spins.. how would this electric turbo control its speed?

 

wow, you seriously think you have a supercharging spinning 65,000 RPM? wow buddy you must have turbo's and supers confused. rofl.
a supercharger spins a lil faster then engine rpm, depending on what stage the supercharger is (different pullys)

 

you should have researched before you spoke michanic. there are definitely super chargers capable of those numbers. i looked it up. still, significantly less then a turbo is capable of
