hey guys i was wondering whats with these cheap supercharger things they got on ebay do they actulaly work?any1 mind telling me.

If your talking about those electric superchargers thier claims are ridiculas do not buy it. they do make a super charger fo the 8th generation galant by ripp mod. I kno someone selling a stage 2 sds kit for 1,200 if your intrested. ill post up someone writing to the company about thier "super chargers. Yes this guy really knows what he is talking about (and hes also helping me build my motor with tech support)

Well, as soon as I saw another "Electronic Supercharger" post on a board I
frequent, I was, as usual, annoyed. Companies believing that they can sell off
these fake products by quoting blatantly false information and making
outrageous claims that attempt to con the less mechanically inclined members of
society is ridiculous. Most of the time, I stick to my typical arguments of
pressure vs. airflow with regards to displacement, compressor efficiency, and
turbine speed. I'm going to do something a little different with you this time,
though. I have a few questions and a few comments about some material on your
site (http://www.esuperchargers.com/index.html) concerning the Jet Stream
Electronic Supercharger.

1. Your first claim: "The Jet Stream™ Electric Supercharger is capable of boost
levels up to 2psi!!" That's great. I doubt it is, but even so, wonderful.
You've essentially done nothing but provide me with more ammunition for my
later arguments. In and of itself, this increase in boost pressure is
meaningless to the more educated members of the car tuning world. Get some real
statistics and I will be glad to even consider this as anything less than a
logical fallacy.

2. "...immediately be capable of delivering a 5-20% boost in horsepower
throughout the entire RPM band GUARANTEED or your money back!" So, a 20%
increase in horsepower throughout the entire RPM range? You're trying to tell
me that you've discovered a device that for $80, will increase power that
dramatically? If you believe that, I doubt you're even capable of reading a
dyno sheet. In your response, please attach dyno sheets, along with a link to a
video of the dynamometer metering your test car. You won't have either, because
you're making things up.

3. "Gain up to 2psi equivalent boost, from 750cfm airflow" Ok, now we're getting
some more numbers. The problem is, those numbers are all messed up! Silly you.
You must be strapping these electronic superchargers on some pretty massive
engines and have gigantic fans inside these things to be able to move
approximately 53lbs/min of air through a motor! Wait, after reviewing your
previous claims, I think you need to increase your claimed power increase
numbers. 53lbs/min is typically good for around 450hp on a decent motor. You
really should start talking about 150% increases in horsepower; you'd get a lot
more business that way. Your claims are extremely faulty, as is your mastery of
the English language. Tiny electronic fans do not flow 750cfm of air at 2psi
pressure. Boost pressure increases in and of themselves do not mean jack squat.
Your CFM numbers are all off. Next claim.

4. "Superchargers capable up to 24,000rpm" What? 24,000rpm? Shaft speeds of even the largest, most efficient compressors are around 95,000-100,000 at full
pressure. Again, let's go back and review your claims. 750cfm @ 2 psi @
24,000RPM shaft speed? Nuh-uh. Not working. So, seeing as you are a "respectable" company, I'll assume you mean engine speed, since that is the only thing even coming remotely close to making sense in this equation. At an engine speed of 24,000rpm, which is essentially impossible in a street engine, this fake supercharger of yours would choke the life out of the motor. Even if your fan could flow 750cfm, a low-displacement (3.0L) engine running 24,000RPM with an assumed volumetric efficiency of 100% and a 1.137pressure ratio (aka, 2psi) would require 1446.35cfm of air a minute. That's almost twice as much air as you claim you can flow. Oops, wrong on both counts. Next claim.

5. "Not harmfull to your car in any way" How about when the little fins break off your supercharger and go careening down your intake path, only to be shattered and sent into the cylinders or get crammed somewhere in the intake runners? Or how about when your supercharger fails or overruns itself, knocking the air/fuel ratio off, sending your car into a detonation or rich mixture cycle that will destroy it very quickly? Ah, that's what I thought. It's BS.

6. "Increases your cars gas mileage by up to 10%" Please tell me this is a joke. If your device increases airflow by as much as you claim, there is no way in hell you are going to see an INCREASE in gas mileage. When you make more power via increased MEP in the cylinders, you lose gas mileage. It's as easy as that. This is such a BS claim that it was hard to stop laughing long enough to write this email.

Anyway, in closing, I'm going to make sure that everyone on every board I go to sees this email and knows your company is full of ****. Your product is fake, your ideas are fake, and your knowledge of the general dynamics of forced induction systems is fake. Either revise your information so it is correct (and provide flow bench results and real dyno graphs, not the fake ones from your site)or I can guarantee you your company is going to see a major hit in whatever sales you are already putting up. Understand that these claims are false and making them without a shred of reality of evidence to support them is wrong. Please respond to this email so we can get things straightened out quickly. Thank you.

I concure. Can we sticky one of these? Not that even that may help all the questions.



engine running 24,000 rpm? I don' think that's what you meant. Not trying to be a ****, just trying to keep all the info good, and in one spot.


:amen:

This will at best, plug your intake path at performance RPMs. It will just not work as advertised, and most likely hurt your performance.

iv been looking at these recently and im undisided
the ones your talking about do look like rubbish but i have seen others that look a lot better

would like to know what you think

http://www.electronicturbosystems.com/1.htm

http://www.electricsupercharger.com/

both crap.

same deal, different shape. the funniest part is that an axial fan can't build boost. That one that looks like a tube with a filter on it is by far the most blatant attempt to f*ck up and skew dyno results I've ever seen.

NOTHING will give you that dyno curve that they showed. you just can't bolt something on and have it give you EXACTLY 5 hp across the entire rpm band. Unless you call a photoshopped dyno curve a modification.

There is no 14 volt electric motor that will make horsepower on a car by bolting it on infront of the mass airflow sensor. None. Nadda.

Yea,What he said :clap: ...must say though,very impressive websites,easily fool the ill informed

take a look at the dyno for the mr2 turbo....that is the worst looking dyno i have ever seen.

Hi i was just searching the net when i came across this post and just thought id add my story too it.....
I have been stupid enough to buy an Electronic Supercharger from http://www.electronicturbosystems.com/1.htm#
Basically all it is is an air filter connected to a metal pipe(sprayed with chrome effect paint) with a fan inside.
I couldnt wait to fit it and wire it up so i took a day off work to do it and try it out.....Well thats where my excitment ended.After spending hours trying to find a way to get the wires from the under the bonnet to the switch id put in the dashboard i was finally ready to test it.....
I found a nice quiet straight road, flicked the switch and........Nearly woke the dead with the rather loud noise the fan makes,so i turned up the stereo and put my foot to the floor, Now bare in mind my car will do 0-60mph in 6.5 seconds before i added the so called supercharger,I was expecting to feel a difference with the supercharger switched on......How wrong was i!....i must admit my first thoughts were WOW! it seemed to reach 60mph in no time so i put the car into 3rd expecting it to really take off but all i remember thinking was "funny!! the fan seems to have quietened down alot"(the cd was changing so the music had stopped)So i pulled over.popped the bonnet and, yep, it had gone quiet, in fact it had blown the 30amp in-line fuse.
Over the next week i went thru 5 other fuses.each time the fuse blew after only being on for between 10-15 seconds.Being rather disappointed at this i emailed ETS and told them the problem.First i was told to try a 35amp fuse as maybe my alternator was faulty and was generating too much power which was why the fuse kept blowing(Now im no whizz with cars or electrics but surely if that was happening every fuse in my car would blow...lol) i tried it anyway and the fuse lasted all of 5-10 seconds.
Anyway to cut the rest of the story short, Ive sent the fan back to ETS and they have said the impeller and motor are both un-repairable.It seems the impeller had melted and become mis-shaped. ETS have said the likely cause of this is over or constant use.........
I'll leave you all to decide if you think running for 20seconds max is considered over use, Personaly i dont and i would advise anyone thinking of buying one of these so called superchargers from either ETS or anywhere else that sells them NOT TO!!!!
ETS are sending me a new fan free of charge but dont think i'l be fitting it,I'l just connect it to a battery and use it in my room when it gets too hot in the summer...cos thats all its good for......
By the way if your wondering if it actually made my car any faster in the very short time it worked then no it didnt, Since driving around with just the air filter that came with it i've noticed thats the only thing that has given my car a slightly bit more power...The fan makes no difference what so ever.....

sorry to hear about your misfortune.



now thats just a load of crap. so they expect you not to use it? :lol:

well i dont know about you guys but i actually got one installed on my 2003 lancer oz and i like to dyno my car after every mod i do. but surprisingly the electric supercharger actually gave me a 12 hp difference at 5000 rpm, but through out the rest of the rpm range it wasn't really making that big a difference. But keep in mind that i had my ecu tuned to get real gains from my supercharger.

That dyno sheet for the MR2 looks like the '98 Dakota I dynoed...when the throttle cable snapped!

that guy 2 posts up.. so a little fan with a filter mad a difference?

i couldent agree more they have to be crap and even when your not using it its gota jam up air flow and if it dosent id be worried that the device isint constructed right. just for fun im a buy the plans and build it to see how much crap it really is, then sell it to the dumbest highest bidder i can find.

guys if u want cheap power theres a better way for "free power" and you proly seen them before.
leaf blowers thats right leaf blowers
im a landscaper so we use em alot and sum of the higher end ones "stihl" blower backpack blowers can whomp out upwards of 10psi or move air at right around 180mph depending on how u want to look at it.
we hooked 1 to my tempo and ran a throttle cable to the accelerator, started it up and blew 13.472 ON THE QUATER MILE IN A TEMPO A 2.3 8 VALVE INLINE 4 P.O.S. BOAT WITH 160K MILES :banana: we also toasted the valves but it was fun
heres the link to check em out

I found one that works I tink it dooes :blush-anim-cl:

http://www.boosthead.com/home.php

They said that SportCompact did a test and it worked fine in the 1/4 mile I might get one if it's easy on easy off :)

i think that it is hilarious when they take a electric radio controlled airplanes duct fan put it on a car and say, "there you go, you now have a electric turbo." this is what a E-ram supercharger is. then again there is my favorite e-bay supercharger that has the high flow air filter attached to it. this is a blower motor for a boat. you know, the part that blows the air conditioning or heat through the cabin of a yacht. the only horse power gain your going to get from this is from the high flow air filter. then another favorite thing about both of these types of electric superchargers is the fact that they don't actually use a compressor fan.

look at the way the intake side of a turbocharger is. the impeller blades form curves, almost scoops, scooping the air into the compressor. then once the air reaches the inner most part it. the air then sort of pushes or slides outwards towards the edge. reaching the 2nd section of impeller blades. which are like the primary impeller blades only backwards to force the air out of the compressor. this causing an effect of compression in a closed environment. this being the reason why when a turbo charger seizes your car will bog down and stop because the engine is then suffocated. when a turbocharger's waste gate is broken and completely open your turbo is still spinning enough for your vehicle to work, but if it seizes your car will stop running.

the same thing will happen with a supercharger. if it seizes not only will the belt snap off no longer running your alternator or what ever else its connected to but the engine will no longer have the air needed to function. because these systems are ran with parts moving so closely together it is unable to breath properly when they are stopped for whatever reason they do. if you see any electric superchargers out there claiming to actually work they are required to use a system that is nearly the same way. the Thomas Knight system works but is almost as expensive as a regular turbo system and has no extra part you can buy to give you more air displacement than what it comes with. plus you have to run three batteries in your car for it to work and it only works like a nos system you get to a certain speed and push a button, the only perk is you never have to refill a nos tank to use it again. these guys use a actual supercharger to run their system, here is the link to that.

http://www.turbomagazine.com/tech/0406tur_...rger/index.html


then there is another electric supercharger site called full on speed. they also have a product that works the same way like a nos system they have it with the intake side of a actual turbocharger, i think they use hyper conductors in their system so you don't have to buy extra batteries, heres the link.

http://www.fullonspeed.com/

both of these systems are within a regular turbo/supercharger system price range. so i would suggest you just go with the real thing or custom make your own electric turbo kit. if you have a engineering shop nearby its not as hard as everyone thinks that it is. you only need to go to a shop and ask them what you would need to build one. but if your not looking to go through the hassle buy a regular turbo kit and put it on yourself. either way it ends up being a lot of work, and takes patients.

if anyone ever tells you that they bought an electric turbo for less than what these 2 offer theirs for, then you should roll up a newspaper and smack them on the nose and say no, no, bad dog! its a sucker buy. don't fall into it.
