"real" electric turbo
 

ok. My father works at a heating and air conditioning place and I was lokking at blower motor assebly. It's a beefed up plastic compressor with a huge electric motor. I have seen those plastic supercharger peices of ---- on ebay and I know they don't work for ----. The difference here is that furnace exhaust blowers push some serious cfm's.I have a 86 civic si hatch i picked up for a hundred bucks. The only problem is that the electric motor on a furnace runs on 110volts and a car runs on 12volts. I would love to here any comments or suggestions on which route i should go.. this is after all homemadeturbo.com!!

Re:"real" electric turbo
 

did u say electrtic turbo? OH NO Jeff is gunna go bezerk!!! J/K (maybe)

Re:"real" electric turbo
 

why would he go berserk....
try it out, lol.

run a extension cord into your car and turn it on. just have a boost gauge hooked up and see if it makes any pressure. its easy to move air. but can it build pressure without the air coming back the wrong way through the fan?

Re:"real" electric turbo
 

This has been tested so many times its pathetic and it always ends the same way. I'd hate to feed your fire, but you could run it with an inverter. It converts 12vdc to 120vac. Good luck with it man. ::)

I know we are talking about two different blowers but still he's gunna hear "electric turbo" and you wont be able to shut him up.

Re:"real" electric turbo
 

Lol, whatever works guys, I dont care if its electric or not, if it makes the car go faster, more power to you.. Me and PMP, had a discussion about a leaf blower hooked up to a Ford Escort.. Its just going to be tough to find something to give it a good constant power source.

Re:"real" electric turbo
 

you see, this is sad. you think I haven't seen those garbage fans they sell at the army navy store. This is a heavy duty blower motor that is from a furnace. It actually costs about $150 but was donated by my father. this blower purpose is to take the ehaust fumes out of your house after the natural gas in your furnace ignites. It will seriously move some air. I don't know what to do because a: the motor is residential use that runs on 110volts and b: the motor only turns at peak of 3300rpm. I any more comments would be appreciated as long as you don't talk ---- and tell me it's already been done and failed.

Re:"real" electric turbo
 

All I know is that if I could get my hands on a bunch of electric turbochargers for a good price and sell them all on ebay I would be a millionare by next week.

Re:"real" electric turbo
 

look man, it wont work...
you cant make power from nothing which is essentially what your trying to do.
Lets pretend the 12Vdc to 110Vac conversion with enough amps was enough to power the fan and the fan needs 100amps and thats what your alternator makes but only makes that much power when it is under full load... so your taking 100% of engine power to run the alternator to power the blower. Do you see how it wont work?
Im having trouble explaining this but if you ever do anything engineering related you will understand.
Basically the same way as how you cannot lift yourself up by grabbing your feet and pulling upwards like people in cartoons do.

Re:"real" electric turbo
 

Yeah, you probably would be a millionare because people like my dumbass neighbor will buy them!!! This kid put it on his Ford Probe. It only goes one speed and it didn't do crap for him. haha, but an exhaust blower, that might work. I don't know is it only one speed? You might have too much air at idle if it's one speed. But I say go for it, I want to know what happens too. :)

Re:"real" electric turbo
 

dude it takes power to make power and exhaust gas is wasted power, think about it its gonna take power to turn that thing.

try it out and dyno it, would be sweet if it works. but i doubt you gain anything and it will sound like a squirrel under the hood, the real ones i have seen are 700cfm and claim 3-7 hp. and thats for $300...

ill take the 55 shot for $500 pat

Re:"real" electric turbo
 

i am trying to find a motor that is not rated at 100 amp draw, and besides they do wind alternator to 150 amps and so on.i understand the engineering part of this and this is why i ask questions so that others could possibly help me and not ridicule.

Re:"real" electric turbo
 

I think it sounds like it'd be great if it worked out! I agree with Jeff that if it makes your car go faster, go for it. Even if for just like 20 HP, it's better than nothing. It's not totally power out of nothing... wouldn't that be what a supercharger does too? it takes a bit of power from the crank and converts it into forced air into your intake. Who says that can't be done electrically? (I may be way off, my alternator knowledge is limited)

Also, wouldn't you need a way to set up the wiring so that it only turns on full blast at wide open throttle? Then you would have to wait for it to get going.... "electric turbo lag" hahaha.... maybe keep it at a low speed and then at WOT have it kick into serious motion, or with an RPM switch like ghetto VTEC setups. And as far as the air backing up into the fan when you gt off the throttle, would a basic blow off valve upstream of the turbo do the trick?

Re:"real" electric turbo
 

I can't believe this conversation is even happening............ :'(

Re:"real" electric turbo
 

Well I've heard that BMW has a electric blower in a car...don't know which though..maybe a prototype. ::)

Re:"real" electric turbo
 

actually ran into a guy te other night at car show, had a 1.5HP leaf blower hooked up, and run off a toggle switch on the dash. he said it puled pretty good, but admitted it wasnt as good as a real turbo. BUT, he said he picked it up at a garage sale for like $25, and bought a 12V to 120V converter at wally-world. at least he hooked it up decently, and it flowed pretty good with it turned off, so he said. give it a shot, what's the worst that'll happen, you'll end up breaking it up with a bat in your driveway.
;)

Re:"real" electric turbo
 

First off I have a 99 Integra GSR (Stock), a 2001 4 Door LS (Stock), and a 91 CRX Si (Stock).

I called a high-end dealer of these electric turbos. I told them that before I buy the item I wanted to see Dyno proof. Well after finding out this guy was a friend of a friend of mine, we took their E-RAM electric turbo and I went to my local shops Dyno. After three pulls on each car the results showed that there was a change... But not in peak HP! It actually decreased the peak HP but on all three cars it did smooth out the curve.

These pulls were performed the same way and the E-RAM was turned on at WOT. (Which was the whole pull!)

So in the end... These things are just not worth it! They give you little to no HP gains and actually act as a restrictor on your intake.

Hope this helps.
flipsoft

P.S. I spent nothing to do this above. I even got the E-RAM guy to pay for the Dyno pulls.

Re:"real" electric turbo
 

thank all of for your help unless you have been ignorant at telling me it will not work. i am going to try this with a fmu and see if anything happens. if it blows up, it was on a 86 civic si that I purchased for $100. i am currently searching for 2nd gen dsm turbo parts for my 98 ex. i already have everything except for the bov, and oil and coolent flanges,and 02 sensor. i realize the electric turbo or blower isn't going to give me gains like a real turbo would, but i am just tinkering.

Re:"real" electric turbo
 

I'm not being ignorant, just stating the obvious. Go ahead and try it. It won't affect me in any way. I won't be out any money and I won't care if you are. I will just sit back and laugh. Good luck with it. At least you are planning on getting an actual turbo. I'll give you a round of applause for that. I'm just not a believer in the electric turbo. Sorry if I sound ignorant about it. If you prove me wrong, then I will be shocked as will everybody else here. :)

Re:"real" electric turbo
 

Actually they should not even classify them as a "turbo" because it is only a fan. Like a leaf blower. It does no compression of the air. It just sucks (pun intended) and it blows. (pun intended)

And after all the testing in the world it made no HP gains. So please do not waste your hard earned money on these cheap gadgets.

Re:"real" electric turbo
 

The Eram appeared to be the only one that may add HP as well, guess that's bullshit too.. Oh well

Jeff

Re:"real" electric turbo
 

maybe if you tried hooking up one of those hybrids,
with the constant recharging half electric engine, or whatever... then use that constant recharging technology to power your POS electric turbo.


i dunoo... just brainstorming ::)

Re:"real" electric turbo
 

Jeff,

You had mentioned the idea about using a leaf blower at one time....did you even consider using a gas powered one? It may sound stupid but its a possibility to try. If it worked you could somehow rig the pullstart and controlls inside the car I'm sure lol it would be funny but hey much easier than a regular turbo setup :p Too bad I dont have one or I would try it

Re:"real" electric turbo
 

or you could hook a whipped cream can to the intake to use the nitrous or a squirrel in the exhaust pipe

wow lets keep thinking of great ways to waste money and not make horsepower

Re:"real" electric turbo
 

a purge fan is not going to work, especially if you mean one of the ones of a high eff unit. Realistically if you can fit a furnace fan to mate onto your intake sure, it will make lots of extra power, we have fans lying around at work that produce 2300 cfm at 10 psi, but with the squirrel cage assembly it would take up as much space as your passenger would. Just power it off an extra battery, and also many furnaces have DC fan options with pulse width modulation for quiet starts, 24vdc for most, just 2 batts.

If you want to try a small purge fan steal one off a powervent water heater, they are a bit bigger than a furnace fan and are easier to get a hold of, but I'm telling you it won't puch enough air, trust me HVAC has been my family's business since 1898.

Re:"real" electric turbo
 

If you think about the way a real turbo works, and the principle behind the electric turbo, you would understand why the electric turbo will not be efficient in any way. Real turbos spin much faster than your electric fan, sometimes greater than 10,000 rpm (can someone confirm this?). Also, CFM is only one attribute that a turbo needs to work. It also needs to be able to compress air, something that the electric turbo will be unable to do (unless it is industrial strength, and weighs as much as your car engine). Also, see how many amps it requires. Your car alternator usually pumps out less than 50 amps at full capacity. Also, that power has to be distributed to your radio, distributor, battery, lights, etc, etc... in addition to your electric turbo. Bottom line is, your car's electrical system would be unable to generate the power necessary to run your electric blower fast enough and with enough torque to compress air.

Also, someone else mentioned that exhaust energy is wasted power, and turbos work by being able to harness this wasted engergy and recycle it back into the engine. This is correct. By running an electric turbo, not only is your exhaust engergy being wasted, but you are spending additional energy trying to run the blower. Sounds like a waste of energy to me.

Re:"real" electric turbo
 

I thought it was about 60,000 rpm, but I'm not real sure.

Re:"real" electric turbo
 

http://www.mcmaster.com/catalog/109/...e/9960kp1l.gif

This is a regenerative blower (thanks to mcmastercarr for the pic). Its kind of an electronic turbo and I need one. The one I am looking for will be able to push 1000 CFM at different controlled PSIs buy using a 30HP motor pushing the fan and the thing weighs a ton, and carries a price tag of $3k.

I figure that after I get done using it for what I really need it for, maybe I could do something stupid with it. Rear engined, electronic turbo'd CRX or something. Since the charged air wouldn't have to deal with the exhaust, you could play with intakes. I'm still waiting for all the specs from the company that makes these things, but I'm sure I'll blow some motor up with it.

Re:"real" electric turbo
 

Granted that pump would probably work significantly well but how the hell are you going to power a 30hp electic motor?

Re:"real" electric turbo
 

Hey I have an Idea. Let me know if anyone has the materials to try it. Take a cheap turbo you have. Remove the turbine housing. Then mount a sproket on the shaft. Not sure how yet. maybe remove the wheel and place it on the shaft with spacers. Then use an electric motor. The an appropriately sized pulley to get about 65,000 rpm from the turbo. How big of an electric engine do you think it would take to spin the turbo? This would work assuming you had the right sized engine and you would have almost instant boost on demand without all the headaches of building the exhaust system. Now can anyone make it work???

Re:"real" electric turbo
 

I cant really tell if your being sarcastic or if your serious about that. Even if that was possible it would be much simpler and probably cheaper to just setup a turbo kit. Really its not rocket science... how fast you want to go is all going to come down to how much you want to spend. You may save some money but speed costs so just fork it out and do it right.

If anything I would suggest another gas engine to power an alternative air pump, never seen it done though.

Re:"real" electric turbo
 

I'm just pretty much joking around with ideas for this thing. I really don't think it is going to be a single phase motor, and I am going to bet that there is a huge draw to start it spinning (it probably uses a huge cap).

I mean if it was a simple single phase motor, I would just use an inverter and do what needed to be done to get it the juice. I guess that if you are adding a ton to a car with a regenerative blower, another 200 or so pounds of generator isn't going to bother you.

Re:"real" electric turbo
 

I was actually serious. Thats part of why I asked how big of an engine you would need. if it could be packaged in something about the size of a stock turbo woud work great. I admit that on a honda its pretty easy to do a turbo. There are alot of other cars out there that its not as easy. Not saying that it would be better but there are some good points too it. Less underhood heat. Less piping depending where you mount the unit. Things like that.

Re:"real" electric turbo
 

Todd are you suggesting getting a dremel and hook it up to the end of a compressor wheel and spinning the turbo up ;)
I dont know what kind of electric motor that can spin that many rpms, with low amps, and be so instant to make enough power. Its a neat thought, but I think I like using exhaust manifolds ;D

Jeff

Re:"real" electric turbo
 

Jeff.. yeah a dremel type tool/motor. but use pulleys or sprokets and a chain to increase the speed of the turbo. Gear it so if your tool spins 10k rpm the turbo will spin 60k. I'm just thinking here. Not that it would ever replace the way turbos work or anything. Mainly just thinking outloud. I like to play with junk like that and figured someone else on here might also. Have you guys ever seen the turbo jet engines? I always wanted to build one of them.
