http://www.electricsupercharger.com anybody ever seen one used on a car? If it really worked it wouldn't be that bad of a deal 1 psi of boost is better than none.

 

looks like a scam.

 

Why would it be a scam?

The concept is not all that far fetched.

All the fan has to do is blow air faster than the intake stroke can pull it in, and there you have it.... in stead of vacum, you have boost. And they aren't claiming all that much from it power from it.

Don't know if it would work. It all depends on the fan (ok, the fan's motor...). I'll admit that I wouldn't by it until I see some data, facts, and figures proving its performance, but the concept isn't all that far fetched.

its crap

it puts a load on the alternator which in turns puts a load on the engine. It also creates turblent air which is bad for performance, so any gains that it might give by producing 1psi of boost would be squechled by the poor airflow quality.

 

I give the E-Ram 2 of these--> . In other words, I wouldn't buy it

 

but at 6000rpm its not gonna let enough air into the engine

scam

 

Put a nozzle on it to blow up balloon's...it'd probably be more effective.

 

For 299.00!!!! - Rip Off!!!

 

it takes a ton of horsepower to drive a supercharger; like 20+ hp at high rpms. that is called "parasitic loss".

for this thing to be effective, it must pressurize high volumes of air into the intake tract....

have you ever seen a 20 hp electric motor? we use them here at work all the time to power large water pumps. a 20 hp motor is huge, and heavy.

i doubt that the e-ram has a very powerful electric motor (or it would be very difficult to fit into the engine bay) and i doubt it will do much.

sounds like another "tornado" to me.

good luck

Tell ya what...I'll take a **** in your intake, and you can give me 150 bucks.

It'll do the same amount of good for your car, and it'll cost you $150 less than that piece of crap.

 

i would save the money for something else...

 

LMAO It looks like the bilge fan in a boat. I can't see it doing much performance wise.

 

This has been discussed before, way back when... final word was, it's a fan, not a compressor. Superchargers typically compress the air by moving it from one place to another, as in a Roots blower, but this doesn't have any capabilities for compression.

 

It will become a restriction
at high engine speeds.

its poopoo

 

i would seriously like to see someone buy that thing and do dyno tests with it.........just to prove that it does or doesnt work........

 

Do the math. If you have a 2.0l engine, it consumes about 2.0l per cycle, * rpm / 2. So at 6000rpm, you need at least 2.0l * 3000 = 6000l per minute. And that's for exactly zero boost. Does it do that? Now double it to get any sort of boost. Does it do that?

There you go.

 

if you do decide to get one dont get that e-ram POS get one of the ones off ebay, and not the cheap *** white ones, there are some that are selling for like 50-100 buks that look just like mini turbos ( the gray ones). i got one just to see if it would realy help and it improved my average track E.T. by about .5, dont know the exact hp gain, never did a dyno test, and if you get one make shure you get a good high flow filter, like one that is designed for a real turbo.

 

get your car dyno'd with it off and then with it on and post the results that should end the speculation over wether or not this thing actually works. If there were gains across the power band then i would consider buying one
