they actually do work a little.. i worked on an altima for some retard a few years ago that had 1 of these.. he picked up quite a bit of acceleration from a standstill and rolling at 25.. would i use 1 personally? no, i prefer the real thing with a blowoff valve ;)

I'd have to see dyno results before I'd believe that any of those "electric turbochargers" make even a single horsepower on any automotive engine. I'd bet, in fact, that since one of those silly little bilge blowers can not possibly move as much air as a car engine would require at anything other than idle (and would certainly not be able to produce boost with any significant airflow) that they would actually create a restriction and reduce power.

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.

lol, I just looked at the ad :rollin: Says it draws 3 amps. To generate 3 PSI of boost at the say, 500+ CFM of air that an engine would suck in at WOT and near redline would probably require 300 amps...

The dyno sheet also says a 2002 focus 2.0 ztec has 240+ hp and over 200lbs of torque. I don't see how that could be con-strewed into a subjective example of a gain on a stock motor dyno'd.

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.

i'm half tempted to buy 1 and put it on my sonoma with a boost gauge, just to see if there is in-fact any increase in pressure.. i know my leaf blower makes a difference, ask me how i know LOL
