Please answer before you close. Do you guys think this is worth buying for start if im low on cash flow?

lmao, hell no. worthless.

*Closed* lol.

I think this is just one step up from the Turbonator, isn't it? Electric superchargers are a scam. I read somewhere that they actually restrict airflow once they're installed.

for the $400.00 you're going to drop on that crap, instead get a cat-back exhaust system. at least it'll do something for the $

got this off a Ebay Guide heh, this is actaully true.

There are some folks selling "electric superchargers" that are pulling a fast scam. There are others that are legitimate. Sure, it is absolutely possible for an electric supercharger to work. If an axial flow fan or centrifugal blower can far exceed the air flow that an engine normally requires. (such as 500cfm for a V8 or 250cfm on a 4 cylinder engine) , then yes, positive pressure can be generated. How much is determined by the POWER of the electric supercharger. A quick determination of the potential power of an electric supercharger is in its current draw and applied voltage (usually 12-14 volts). An eRAM electric supercharger for example runs at near 60amps, so its power draw is near 840watts. Its unrestricted air flow, is near 1000cfm. It has no restriction, vs a normally configured intake tube, which is usually between 2.5 and 3" in diameter, due to its 3.5" diameter and aerodynamically designed construction. In fact, on a flow bench, an eRAM flows as much as a 3" straight pipe! The actual measured positive pressure in stock air box configurations and in cold air intake tubes, is near .5psi. The negative pressure (vacuum) in all air boxes and even cold air intake tubes is also relieved giving a net pressure gain of near 1% (or near 5% gain in density) this translates to 5% gains to the rear wheels in HP.

Now, if you look at most all the electric superchargers, except the eRAM , you see the current ratings of them , falling in the 2-10amp range. This is because these fans are really boat engine bay vent blowers or automotive air conditioning and heating blowers. all of them are not designed for creating pressure and only have between 25 and 100watts of power. Forget simple math here, simple physics say it takes power to create pressure at a given flow rate. If you dont have any power to work with, you certainly cant expect any pressure to be created.

As far as the current capability of most automotive and motorcycle systems. Anywhere between 200 and 500amps are possible for short term duration. The charging system recharges the battery between bursts from a starter starting the car, or even the eRAM working on only full throttle operation for several seconds. charging systems respond by voltage drop on the battery. (the larger the voltage drop on a battery, the more the alternator trys to boost it back up with higher current flow) A quick test of the capabilities of the electrical system is shown on published eRAM tests. Since the voltage applied under running conditions still allows for charging of the battery at near 14volts, there is no issues. Even dual series eRAMs (two units), draw more than 120amps. charging from the alternator is maxed out at near 80amps for small cars, but the battery can handle quite a bit more. In this application with high current draw, the voltage drops to under 12volts for a short duration, but the applied power to generate pressure in the 1.5psi range is in the 1600watt range (thats near 2hp of applied power before losses are calculated)

I hope this clears up some of the misconceptions relating to the electric supercharger. They do work, IF you have a system that can produce pressure at a given flow rate. This means you need a system that draws more than a few watts. You need a system that draws near 800watts if you want it to produce any pressure at all.

Moving forward, there has been work done in the area of DC brushless motors that draw near 250amps and are much more efficient . These motors running axial flow blowers are known to create near 2-3psi. They are quite a bit more expensive, but it certainly shows the potential for electric superchargers in the near future.


I think we can end this discussion.

I dont know. I dont think they do that much if any. There was one of these RAM ones on ebay that was used and I thought about buying it to try it out cuz it was like 100 bucks but I never did.

I wouldnt pay the 300 or 400 for it tho.

again, its a scam. even the one that they say "works" is only for a short time under WOT. so the "5%" hp gain is for about 2 seconds, when your mashing on the gas. ABSOLUTELY POINTLESS.

If you even have to ask the question on if that is worth buying or not, you shouldn't even be touching your car.

What the hell are you talkin about kid im just asking some feedback on it wow grow up

Exactly I don't even know why you have to ask the question though when it's been around for so long everybody knows that they're a scam. Any money anyone spends on that might as well donate the money to charity, it'll do the same amount of good for your car.

But I didn't mean to come off so harsh, to me it's just a pointless question and I just forgot to take into account the fact that not everybody has heard of them and the scam that they are. So I do apologize for coming off so snippy, cause that was never my intention, I just got carried away.

its all good , thats why i posted on here cuz i didnt wanna get ripped off lol

HAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAAHAHAA

Send me ur email, il send you my account number and i want you to deposite that 399.99 there.

He was simply saying that:

If you question the value of a particular mod to your vehicle, you probably shouldn't buy it. And as a general rule, anything that is a short-cut to a larger mod (the turbonator, or this) is most likely a scam.

lol hey man these things are awsome...i have one on my 3g and it did jack shit lol...nah but on a serious note i didnt spend my hard earned money on that and u shouldnt eaither. go turbo you will be hella happier...remember the saying "you get what you pay for"...

tru dat man

man we're still on this subject?
