Has anybody thought of making a supercharger with an elctric fan instead of belt drivin worm gears? What would be the problems with this? What would the air flow numbers have to be? Is this possible? If it is , I'm gonna do it. Any body else who wishes to do so can also. thanks-
 
I remember seeing some time ago a product just as you described. But realisticly it doesn't work. The power requirements to make such a electric blower work on a car would mean you'd need all and some more of the power output of your altenator! You can only get the power needed to blow air into the motor from either the exaust gas (turbo) or directly driven by the motor (supercharger) Just my 5 cents.

8) there used to be an electric supercharger on the market a couple of years back that was basically a paxton blower that used an electric motor to turn the impeller. it made about 3 psi boost. i havent heard anything about it since.
 
I remember those. My question is whatever happened to electric turbos? I haven't seen one in years, it's like they all vanished from the face of the earth.
 
how could a turbo be electrically powered?
tryin to visualize, but just can't...
........ maybe if i concentrate harder..........

:boom: :boom: :boom: :boom:
........... uh-oh

AAAAUUUUUGGGGGGHHHHHHHHHH!!!!!!!!



EDITOR'S NOTE:
I apologize for Asa67_stang's strange behavior, it is late at night (for him, remember, he is on night shift) besides, he has been hanging out with too many "crazy Kiwi's" the main perpetrator in the corruption of this fine young man being a Fordsix.com member going by the name of Xecute.
Once again, I apologize for his behavior, that will be all.
 
Well, it would just be half a regular turbo. An electric motor and gearbox driving a rotating single vane compressor. But the (serious) power for the electric motor has to be sourced from an extra alternator or something. Might work on a drag car.

you'd need something on the order of a 20 HP motor have enough power to make any boost. Its not going to fit under your hood. Also 20HP = 15kW and at 12v that's 1250 amps. :shock: You'd need one hell of an alternator
 
Most turbo compressors spin in the ballpark of 100,000 RPM at the point of peak effeciency. You would need some serious gearing and a really powerful motor to pull that off. Besides, even if you could get an electric turbo working it probably wouldn't be much more effecient than a conventional turbo, and it would be a lot more complicated (ie. more to go wrong).

If you really want to know how well it works ask the guy that forked out $250 for this: http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=2414119823&category=33742
 
i did some lookin around i i fugured out a half ways decent way of doin it.
it would require a 180 to 200 amp alt, a 2000watt (i think) power inverter, and two big electric leaf blowers. The blowers would have the cfm but i aint sure about the psi. when u look at them their design is like a turbo. goofy idea anyway
 
All points are valid but I have yet to find a turbo that was affordable, even from a wrecking yard. Could just be my area I guess. I would love to convert to turbo. I belive it would be the best of both worlds. When crawling(offroad) it wouldn't really change anything. But when I come across some mud just spool it up and away we go! And it just might give me that extra oomph to beat that guy with the 400 chev. :hmmm: I'm not worried about fuel delivery, the EFI system I plan on using uses a OX-sensor to monitor and adjust the air/fuel mix.
 
Superchargers eat a LOT of HP. It takes a whole lot more HP than a leaf blower can put out to make boost. A centrifugal blower draws something on the order of 20HP to make 6-8 PSI on a 5.0 engine, maybe a bit less on a 4.9. Leaf blowers put out a lot of CFM but their airflow would stall if you hooked them up to an engine.
 
now thats a thought how big a tank would you need to
supply 6# for 10 seconds
 
Well a 300 @ 5000 RPM uses 434 CFM at 100% VE. At 6 PSI that's going to be somewhere around 611 CFM, so 10 sec would require around 102 cu.ft. at 6 PSI. Assuming your tank is rated for 120 PSI, you could compress that by a factor of about 6.5 so you'd need a tank a bit larger than 15.7 cu.ft. Once you add in all the losses and inefficiencies, you're probably looking at something bigger than 18 cu.ft which is 134 gallons. I'd guess a 150 gallon tank would work nicely.

Now, if you want to look at using a high pressure air cylinder, you might be able to make it work IF you can find a regulator big enough.

Who are you going to get to drive this bomb????
 
Methinks StrangeRanger doth protest too much. Admit it, you wanna be the one to drive it. :twisted:
I like your thinking john, but I was actually thinking about a pair of high volume AC compressors like Yorx or something. But A tank would probably work better :hmmm:
Nope the tank would weigh too much. Oh well, back to turbos. How about on of the little ones off of a 4.7 litre John Deere diesel? Too small? How about one off the big diesels....... :hmmm: I'm gonna get in trouble again.
 
Nah, Ac compressors would be lighter. Besides my 300 has all the brackets I'd need to run multiple compressors.
 
8)

Jegs had an electric turbo in their catalog IIRC it was about $650 to make about 5hp.

There are alot cheaper and easier ways to pickup 5 hp.
 
so any thing that runs off the motor uses horspower
so how about adapting a ac clutch to the alternator with
a wot switch that would free up hp when you needed it
and not effect anything when you didnt
