OK THIS MAY SOUND DUMB AND I PERSONALLY HAVE NEVER HEARD OF IT BUT IT SEEMS LIKE A GOOD IDEA.......WHY DONT SOMEBODY INVENT A SUPERCHARGER LIKE SETUP BUT INSTEAD OF RUNNING OFF PULLESY OR RUNNING OFF EXAUST LIKE A TURBO JUST RUN OFF OF AN ELECTRIC ENGINE? THE WAY I THOUGHT OF THIS IDEA WAS KINDA FUNNY. I WAS TRING TO THNIK OF A NEW CHEEP INTAKE MOD AND WAS THINKING OF HAVING A FUNNEL TYPE SETUP THAT STARTS OUT REAL LARGE UNDER THE CAR SAY 3 FEET BY 3 INCHES AND SHRINKS DOWN TO SEAL ON THE MAF, TUS FORCING AIR INTO THE ENGINE ... SUPER RAM AIR!!! THEN I SAID WELL HELL COULDENT I JUST USE A HIGH POWERED FAN TO TO THIS JOBOF THE FUNNEL AND JUST USE A SMALLER FUNNEL.... I KNOW ITS PROBALY BEEN TRIED SOMEWHERE BUT IT SEEMS LIKE A VAIBLE IDEA JUST THINK SAY A DUCT UNDER THE CAR LIKE THE SLP DUCK BUT JUST 2- 3 TIMES AS BIG ON THE END BY THE CAR AND AIR TIGHT ALL THE WAY TO THE TB AND A SMALL BUT VERRY HIGH POWERED FAN DEGSINED TO SPIN UP FASTER WITH RPMS... I GUESS IT MIGHT BE DOABLE BUT LESS EFFICENT???? I DUNNO JUST BORED AND THINKING OUTLAOUD ANY COMMENTS , FLAMES, ADDITIONS TO THI IDEA ???

 

First off, stop typing in ALL CAPS!!!!

Second, it has been tried. It is a very inefficient idea. It sucks way to much power from the battrey and the alternator has to work hard to compensate for this. Plus an electric blower can't force enough air to make any improvement.

 

Sell the sterio stuff and buy some parts, makes the car lighter as well!

 

It can take up to 100 hp to spin a blower (depending on boost level, etc). A 100 hp electric motor is "huge"! It is not practical to put a motor with enough power under the hood in the area that you have to work in. And, if you could get something in there, you'd never be able to power it correctly....

But, keep tossing ideas. YOu may invent something cool...or lear alot, or both.

 

a buddy of mine bought one of these things for his 00 mustang gt thinking he might be able to keep up with some of the ls1's if he had a lil extra power. basically all he got was a slightly glorified cold air intake. netted a gain of about 15 hp, and he had the car dynoed before and after as he was going to get a chip for it. and as the guys said before, the power source it needs is redik! If you can find the power source and keep it feeding the damn thing, 15hp is 15hp, take as you will, if your *** is sensative enough you might feel the net gain at the rear wheels, you probably wouldn't. id say, save teh cash, purchase a NX Nitrous kit. i haven't gotten myself my own LS1 yet but my day is coming, and the one im eyeballing now has a 100 shot and a very nice looking dyno sheet that comes with it.
just my .02 good luck.

Do a search [~Google]. I don't a have link now, ..wait, I did the search: there is a place called www.electricsupercharger.com. They sell it for ~$300. It's a compact sized powerfull electric motor ( 700w ~ 1hp), which quickly spins when you go WOT. Creates something like 0.5-1psi of pressure. The model they sell is advertised for <5l engines only, so it apparently doesn't have the capability to fill out huge 5.7l+ engines, but you could use 2...
It only works when you go WOT, and so it really doesn't drain that much power from your battery, think starter motor. The gains are like the guy above said ~10-15hp. It is what it is - nothing less, nothing more. It won't trasform your stock engine into a monster, but it is a credible compact poweradder.

 

I'm worried. The "electric supercharger" (as seen on EBAY) will not make enough HP to support stock power levels (you may lose HP with one). THe only benefit could be from other modifications to the intake that were made in an effort to install it. Lets consider .5 psi of boost.

Atmospheric pressure is 29.92 inches of mercury (at sea level on an 80ish degree day), this is about 15 psi.

If we consider that our engines make 310 hp (cough, cough) at the atmospheric 15 psi (slightly rounded pressure number, but it is close and will work for this discussion). Then, at 15 psi of boost we could make 620 hp (not allowing for heating of the intake air charge, etc). 2 times as much air and fuel, will be 2 times the power (again, not considering blower effeciency and heat...the numbers will actually be lower). So, if we divide 310 hp (the "gain") by 15 psi ("the pressure"), we get 20.6 hp per psi. So, if this thing was capable of making .5 psi, it would be capable of making about 10 hp. However, this will need to generate airflow in excess of the amount required by the motor to idle. Even a motor at idle will likely require more air than this little 3 watt electric motor can produce (it takes over 700 watts to equal 1 hp and it can take up to 100 hp to turn a blower, meaning, this little electric motor "isn't doing much"). I suspect (optimistically) that this little blower could at best, make 3 hp at idle and begin costing you hp as soon as you open the throttle. This is NOT considered a "credible" mod by anyone who has ever studied engine airflow and how it equates to horsepower production. I would run away from anyone selling these items (most of them are actually ventillation air pumps for boating applications, or used by road racers to pump cool air into the drivers area or to help cool brakes). An electric supercharger would require an electric motor that is nearly 1/2 the size of the motor that powers the vehicle....meaning, it wont fit.

I suspect the "dynoed" gains seen in the post above was due to modifications made to the intake to install this electric motor (think, cold air kit) and not by the motor it's self. Save your money and run away!!!!

 

Had a friend who thought this was a great idea, nothing could talk him out of it. Anyways, the turbine came apart and he destroyed a 3500 mi LS1. The general rule I use is, if it is not used in any racing applications anywhere, there is a reason. There is a also a reason a head unit is 2 grand.
