Make-shift Turbo charger.....ARE YOU KIDDING ME

[MotorWerkz]

senses can be false ...

if you were standing outside your house, can you sense how many temperature accurately? no

if you were to see a speeding car, can you sense how fast he is going accurately? no

that's why we have tools to measure these variables.

ask your friend to dyno his tiburon.

ps: i'm not a electric-supercharger owner, or affiliate, but I can't stand people badmouthing a product they haven't tried. at least try and if unsatisfied... then BASH!

[m3racer36]

your right we didnt dyno it but 15% would be somewhere around 20hp and you couldnt feel the difference, thats all i am saying. im bashing through experience not ignorance if a t25 wont build boost on most cars i doubt an electric charger will

[illegalprelude]

this almost reminds me of those Tornado Intakes they advertise on TV that they say gains oodles of power for u car.

[Josh ///M3]

Anyone realize that Foci, even when turbo, are slow as nuts?

[///M Jefey]

HOW BOUT i egt my friend to buy it and put it on his accord then why run it on the dyno...cuz obivously you guys are haters and believers..so this needs proof. But it might take a while, check out the video, the thing can propell its self in the air. but ONE (1) PSI is no comparison to a turbo pushing 15.

[Ghettoraid]

Jefey.. you sound like the kind of person who will buy things off of infomercials. LOL

So what if the thing can push a log, or suspend itself in the air? This does not mean it will work effectively as a "supercharger." Plusthefact.... do you really trust those plastic impellers? What happens if one of the blades snaps off? Seized engine, that's what.

eRam's are a complete waste of $3-600. Even if those dyno sheets are accurate...is this really the best use of $3-600 in terms of hp per dollar? No.

[MotorWerkz]

some people are selling expensive product and it does not increase as much HP as you think, for example, CAI(cold air intake)... this thing does not increase your HP and dinan one is damn fckking expensive. you'll see the pipe that goes down, it's a long pipe and it gets heated by engine.. even though it sucks cold air, it'll still get heated on its way to engine plus the long tube.. it takes more energy to suck with a long pipe vs with a short pipe.

CAI+chip "may" produce unnoticeably power increase

Those things do not work. Plain and simple.

An electric fan is something quite different from the centrifugal compressor found in a FI system.

Using one of those fans will not give performance gains, and in some conditions will RESTRICT airflow into the engine.

The air travelling into the engine will not be forced in at a faster rate with one of those fans due to some simple laws of physics.

Imagine we have an aperture, eg our intake, with our air flow going in. The rate of air flow in is a function of several things including incoming air velocity, size/shape of aperture, air temperature and other variables. We want maximum mass of O2 going into the engine at the maximum rate.
Now what a compressor does is increase the mass per volume ratio of the air coming into the engine. By pressurizing the incoming air, we are packing more O2 molecules into a smaller space, which is going to give us a bigger bang when we combust in our cylinder.
What that fan does, is attempt to increase the rate of O2 entering the engine with neglible compression effect; we are trying to force the same mass/volume ratio of air but at a higher speed basically. The problem is that the speed of air entering the engine is not going to be increased by the fan as it is already pretty much at a maximum for the given conditions.

Now people are going to argue this, but I think there are some vested interests among certain posters to this thread.. ive seen many similar threads on other car enthusiast sites with the objective to promote these devices to increase sales, created by individuals with direct links to distrubutors of these products.
Simply dont buy them, they dont do jack shit, they are poorly manufactured and not designed to be used in an engine environment.

"The air travelling into the engine will not be forced in at a faster rate with one of those fans due to some simple laws of physics."

I am wondering which law of physics it is that supports your claim...LOL

If the fan has the ability to push air *faster* than the engine is *pulling* air, then the Eram will work. And BTW a fan *is* a compressor.

FWIW, the eram probably does not add 15% extra HP "across the range", but I bet it does add something. One thing that I am sure of, people have spent more money on things that offer less performance

[GregD]

There is no way the fan will blow air faster into the engine than the effect of the immediate low pressure drop caused by combustion in the cylinder. We are talking a massive change in pressure in a very, very small amount of time, giving a very high entry velocity.

i don't have to smoke crack to know it would be bad for me.

this debate has been going on for a long time. i've yet to see a dyno sheet showing gains from someone i trust.

which physic law do you use to apply your theory? (bernman is asking the same question)

it obviously force air at a faster rate because it COMPRESS air at 1 PSI (read more at website) and it's bigger than naturally aspirated method.

again: read www.howstuffworks.com go to engine section, and go to question "how to increase horsepower" one of the answer will be : to let more air IN, and this technique has been applied by eRam electric supercharger. it LETS more air into the engine.

the system is different, but the goal is the same ... it's to compress more air into engine. this electric fan is OBVIOUSLY stands lower than F/I (turbo or super charger) because the pressure is only 1 PSI, while turbo/super charger can compress more than 15 PSI ( and the price is also different, eRam costs below $1000 and turbo/supercharger can cost up to $10,000)

bernman is correct, a FAN can be a compressor, as long as the FAN is able to compress air at certain PSI, it's called compressor.

There is no way the fan will blow air faster into the engine than the effect of the immediate low pressure drop caused by combustion in the cylinder. We are talking a massive change in pressure in a very, very small amount of time, giving a very high entry velocity.

have you measure the rate of engine sucking air? the number will not impress you, the fan has more power to force the air into the engine.

[MotorWerkz]

you don't need to buy this stuff... I just like debating some simple physic argument ...

dude your taking up for this peice of shit, you must have one or seomthing, and if you dont why dont you get one if you think there so great
