I saw this in the Turbo magazine. I think, you guy might be interested.

It seems to be a cheap alternative to the real supercharger, with 1-1.7 psi of boost.

Here is a quote from the website :

"Finally, unlike any other manufacturer of "bolt-on" performance additions, we GUARANTEE you will see AT LEAST a 4% increase in horsepower by adding the e-RAM on your intake or we will give you your money back!*"

 

How much hp did they get. i dont wanna hear a 4% in theory bull.

 

Yeah, I wish I knew. Although, they didn't dyno the scion one, they did dyno many cars.

The thing with these is..........I have a feeling the engine can move the air faster on its own than this fan could push it.........................so the fan would actually be an inhibition to air flow.

Do I have scientific data to back this up? No........but it is what I believe pending scientific data to suggest otherwise.

4% increase in HP... WOW! Where can I throw my money away to get this! These units are really not very effective... The drain on the engine from the alternator which powers the unit negates MOST of the benefit. A turbo is much more efficient because it uses exhaust gases which is basically free power.

 

these do work but only get us about 5hp...

(the stock alternator is 80 amps...normal darw while car is running is 38 amps...it has plenty to sapre without inducing a load...)

these are about 1/10 the price of a turbo....

if you want to tune, go ahead and try it...but its a lot of work for little result. just get a regular intake for about the same performance (and a better look)

 

Guys, if you have a chance, read the article in the link below:

Those gains arent bad to me. but at around 300 , screw that .

 

It's crap.
Do some research into Bilge blowers.

 

if it's e-ram it is not a bilge blower. bilge type ones are completely fake but e-rams actually have some benefit.

 

They actually compare their product to other eletric blowers. Check this out:

seems convincing

This is what they mentioned :

Regarding other "Electric boost" offerings like cheap plastic "turbo" looking devices or squirrel-cage ("leaf-blower" style) fans driven by a cheap electric motor:
Again, the concept of using an electrically driven "compressor" for boost is a sound concept, and again, the problem is that compressors are horrible at providing unrestricted air-flow unless they are constantly running at speeds that will also generate pressure. The "electric turbo" will have to be on all the time in order to not create restriction when not energized. This means it will have to use a low powered electric motor that won't draw any significant electrical energy so it won't overheat if used in constant duty.... thus... it won't draw enough electrical energy to generate any boost and will ultimately just restrict air-flow. Also, small plastic squirrel-cage fans cannot rotate at a high enough rate of speed to generate any pressure. This is because the forces exerted on the unit if it were to rotate at a high enough speed to generate pressure would cause the unit to self-destruct. It doesn't matter how powerful a motor is used with this type of cheap plastic fan.

Summary:
There is no "free lunch."
Regardless of what PSI is claimed by ANY maker of electric boost technology, what hp gains are claimed, or at what rpms the "fan" is claimed to rotate, the laws of air-flow dynamics require a specific amount of power to generate psi at a given flow rate. Anyone claiming to do what we are doing [Axial-Flow (in-line) fan used to generate HP on an internal combustion engine] is IN VIOLATION OF OUR PATENT, and has no access to the motor technology required for this application.. Also, anyone else using any other style of "fan" based boost claiming ANY HP gains on a car engine without a power source of AT LEAST 680WATTS (48 amps at 13.88 Volts) is LYING, and just ripping people off. [/b]

 

Every amp drawn is a LOAD on the engine.. there is no free lunch... the exchange of power to run this device is not worth the output... better off with a better breathing intake and realize a 2hp increase instead.

 

Intakes are about 4...... whp.

 

In your dreams... 4 flywheel HP maybe... not to the wheels

 

It works only at full throttle (which is less than 1% of my driving time), so it is not worth buying for regular driver like me , costwise. At least, it is good to know that someone actually make it work.

also check out their video, it's kinda cool

5hp and $300 don't match. Waste of time, money and effort. Save up the money an buy a real supercharger.

 

Dude learn how to read dyno charts. Relax and let people do what they want.

 

Haha.. dynos ... they have an accuracy rate thats differs more than 5% for the SAME dyno between runs. Not to mention temp , baro, and other variables. I know, I used to have one in my shop. So you go ahead and believe the dyno charts and some advertisement... it will make you believe you have more power.

And don't worry, Im relaxed from all the laughing... Thanks!

 

I'm getting the about 4whp from reading multiple dyno chrats from different intakes and different sources independent and company given.
