Haha i dont pay for alcohol...underage drinking is "bad"..i was jus trying to make the "electric turbo" big enough to make some power gain...like i said so many people told me yea good idea but can't make it big enough...in reference to the turbos on ebay...so i made a big one.. Now the atx should be able to handle the power..for example the escape.

I also plan on studyin something along the lines of which you did.

Yes you are off with your thinking of the required current draw to sustain any amount of boost pressure generated over the engine's natural CFM draw.

The "blower" motor on the car draws a small amount of current and pushes a handful of cfm and does it with no real resistance.
It should not really be compared to a fan that could generate boost on top of an engine that is naturally pulling in 300 cfm all by itself (meaning said fan needs to push more than 300cfm and do it under heavy load! Then be able to sustain that output!)


What type of power draw is required with a very efficient electric motor:

"If an electric fan pushes 750 cfm at 1 psi and runs on 14 volts at 50 amps, then it will use 700 watts of power." (ERAM's stats IIRC - the Ebay fans I've seen are beyond junk!)

At 100% efficiency this will generate roughly a 10-13HP increase at the crank on the SVT engine. (8-10 wheels) Then factor in the alternator will draw about 2HP back to supply the electricity. The battery takes the brunt of the "initial" current draw. Sustained draw comes directly from the alternator though!

So "technically" you could get a maximum gain of 6-9 wheel HP at 100% efficiency for ~$300. Not bad HP per dollar for our car really.
However make sure you have a good quality battery (optima for instance) to help with the added strain on the electrical system. Also alternator replacement interval may be sooner too.


The ERAM is not a "joke", though it is not as awesome as the information would make it look.
The EBAY junk is a joke. Plain & simple.

I'd honestly recommend not pushing the limits of your tranny. The rebuild on my ATX was well into the $3000 area. Save your money and your poor car's tranny and when you have the money, buy a cheap beater with a bit more displacement (an 88 5.0, for instance).

BTW, the more life you can get out of your alternator, the better; try replacing it in under 2 hours, and if you're still smiling afterwards and not missing any fingernails, by all means continue.

well the manager at my work said he would try it on his car, he has an old vw jetta(not daily driver, just toy) and has a lot of extra room in his engine, he was impressed enough by my contraption to be the test dummy. Since of course i dont want to relocate my battery to my trunk w/o seeing if it produces any gain what so ever.So that will be going on in the next week or so....we dont have real access to a dyno so this will be driving expereinces.

I planned on installing this in a manner to permit as much airflow as possible and have it activated by a switch. Possibly running it no more than 2minutes at a time so as not to draw power robbing current. I would accept a 10hp gain considering it only cost $40 to make. If you all are intersted i will post our experiences

the ebay stuff is a joke...its less powerful than a my moms blow drier.

I tried building an electric turbo that used an RC jet (electric ) engine that produced 8lbs of boost. The current draw was a lot! the only real way I got a performace gain was by running a seperate power supply at the track, not connected to the car, and could only be charged after each run. It was a huge pain and not worth it. It was a cool project since I had the parts laying around, but it is not something that will not last over time. I had it set to spin, and then a clutch would kick in to produce boost when turned on. It was a waste. I even had a friend who is an electrical engineer look at it and say it could not be done to produce a large amount of boost.

I say keep playing with your $40 idea, the odds are against you that it will work but that was probaly said about the first prototype turbo and super chargers. If you always do what you always did you will always get what you always got. Who knows maybe you will get lucky and come up with something new after a few tries and redesigns.

Huge wealth of practical experience and basic laws of physics say not.

If you want to increase horsepower on the cheap, start with an old 5.0 mustang (89 to 93). Contours are cool and handle fantastically - but significant horsepower increases come dear.

Incidentally, the first superchargers and turbochargers were developed for military aviation prior to WWII!

Keep us informed! A long time ago my dad put an electric turbo (is electrocharger the proper name? ) on a Fiat with much success. It would be nice to have confirmation that one of these suckers will successfully work with a tour. I was also wondering, if there is enough juice (extra battery?), would a yard blower work? Those things blow like 20 dollars in Vegas
