at least its a 5th gen owner.

thats not the amazing e-turbo in action, is it ?

ur all wrong, its a leaf blower.

What the hell is that supposed to be??

And all this time I've been using it to dry my hair, boy am I a moron!

i saw that car on ebay. i almost lmao. if you look he also has a front mount intercooler not even connected to anything haha

i need to learn. whats bad about it? do u gain anything?

lol so whats the point of the thing?

It's debateable, but don't try it on this site. It's just like talking about abortion around here. This topic will be locked within a few days.

It's purpose is to push air into the intake manifold. It's debated if it's forced induction or not. I want to talk about this thing so badly, but I'm doing my best to keep my mouth shut. btw, some purpose built e-turboes are way different than leaf blowers. I suggest everyone do as much research as you can before posting. I've done a good bit of research on it, but I'll hold my veiw for a while.

Now all they need is the TORNADO and I say that car will be showing some serious hp gains.

doesnt the tornado atomize the air easier or something? i dunno

>

think about it for one second. its a little fan shaped thing... it dosnt do jack.

so ur saying the tornado or eturbo cant help me get my groceries faster?

It won't help me pick up the ladies?

Hahaha you clowns.

i cant beat them vettes?

>
The tornado won't. I'm serious guys, do little research before you flame. There are differences in quality of any part. Like those crappy ebay coilovers, compared to a set if Teins. It wouldn't be fair to say all coilovers are worthless just because the crappy ebay ones are. Would it?

i didnt know they made these. i was considering designing something along these lines for my senior project in mechanical engineering. to everybody making fun of this: this actual product might not be very effective, but there is NO reason it couldnt be. technically it could be done, and be just as effective as a traditional turbo. the compressor doesnt care if its driven mechanically(supercharger), exhaust gases(turbo), or an electric motor. not to mention the advantages this would have both installing and controlability. pressure sensors could be fitted to alter electric motor rpm to adjust boost accordingly (no more boost creep/turbo lag), could control desired boost easily and cheaply ( 5psi daily to 10psi runs?, no problem), and it would also be a convenient option to turn on/off. now with a large engine, this would be tougher to do because it would require a powerful (aka big) electric motor and a high discharge alternator to provide any significant boost. but with a 1.8/2.2 liter engine this is very doable, and actually has nothing but advantages compared to traditional supercharger/turbocharger setup. again though, it would need to be properly designed, and since it seems the ones produced are mainly marketed as a cheap alternative, i question there quality. of course with an eturbo providing significant boost, the other necessities would still be needed such as fuel injectors/pump, intercooler, fuel management, etc. the one disadvantage is efficiency (going to be less efficient than turbo, however id bet its similar to supercharger, if not more), but in my opinion the reliability and installation ease more than make up for it.

...i have an eTurbo, but i'm not going to comment due to the slack it gets here. I know i'll get "flamed" for having one, but i could care less...so save yourself the embarrassment

id LOVE to see some dyno sheets before and after from that thing man!!

Nice right up CelicaST. With adtvances in electronics, it's very possible. The problems I see is they are marketed as cheap alternitives. To make one work correctly it would have to have a fair amount of RD and money invested. There's so much info out there on superchargers and turboes, that it makes them as easier alternative for most. If the right guy felt like doing a e-turbo, I see no reason it couldn't work just as well. I like to compare it to carbs vs fuel injection. When FI came out, the car guys would switch it to carb right away. Some still do this. It's easier and everyone knew more about working with carbs. Besides that, there weren't many performance upgrades redily avalible for FI. But the problem with that comparision, is that race cars when to FI way before they went to street. And it was known that FI would be better for race cars. No race teams that I know of use e-turboes. This might be because there just hasn't been the desire to look into them yet. I think we'll switch to electric cars before e-turboes are popular. But the fact stands, it is very possible to make one work. Even the ones they sell will do something, just help to equilize pressure. That won't produce much of a gain, but you can't deny it's doing something.

I think this topic will actually stay open awhile. Everyone so far is presenting reasonable arguements and no one has jumped in to simply bash on anyone.

i would too, go do it snapshot! but i hightly doubt any significant increase because the eturbos ive seen for sale since i just started looking all arent high power enough to provide the air flow needed. however, manny, dont let that make you discount the idea. there is no reason this cant be done, and very effectively.

I take it the energy used to drive that fan is an electrical source. As such, how much air could possibly be pushed with a 12v fan? The concept is sound (engine management issues aside) but the mechanics given the capability of the components make this something that is not worthwhile.

Notice how I didn't say it was stupid despite my inclination to do so.

im going to say it impossible to even get ANY 12v motor to supply enough air to any combustion motor. no way no how. and lets pretend it does work lol. you still need to upgrade the fuel system and the timing and the sensors. its just not practical. and its only a fan. it can push air yes but it cant Pressurize a chamber.

now maybe a 10hp shop vac fan could do something

very nice ananogy with carbs v FI. but i disagree with you on one point. we dont need any advances in electronics to make this work. i could and will make one, granted i can get it approved as a senior project, with off the shelf parts. marketing is the only reason this hasnt taken off. its similar to the marketing of ev and hybrid cars. ev and hybrid cars have so much potential in terms of performance over a typical ICE car, but the demand isnt there so people get teh misconception that hybrid/ev technology is slow. similarly the demand for this product is from customers looking for a cheap alternative, and so they make them low power so as too not require intercooler, injectors, etc. again, i would very much like to see a dyno snapshot if you can find the time and place to do it

by the way, a bit off topic, but people doing engine swaps. motor swap>>>engine swap. i guarantee you a siemens 1pv5138-4ws24 electric motor paired with high power inverter and lightweight battery pack could outrun a 3sgte. "max" power 203hp, "max" tourqe 332 ftlb. ill post a new topic on it sometime to explain what goes into an electic swap.

*i missed your point about eturbos not being in race cars. thats simple. FI was implemented over carbs because of efficiency, and it was clearly advantageous to carbs. however, like i said before, an eturbo is NOT going to be as efficient as a turbocharger. energy must be converted from mechanical to electrical in the alternator, 12v dc electric to high voltage ac electric in the inverter, back from electric to mechanical in the motor. the engine is going to work harder to develop the same boost as a typical turbo. i said it might be similar to supercharger because of the friction in a roots blower and the mechanical drivetrain, however im just guessing.

im sorry, but you sound ignorant on this. what do you call a turbo compressor? its a fan, a highly specialized fan. its a radial fan as opposed to an axial fan your probably talking about, but still. now your right, a 12v motor isnt going to be powerful enough without very high amperage (but that will cause overheating issues) to supply the air needed, but thats why theres AC inverters and transformers by the way, "it can push air but it cant pressurize a chamber." i would like you to read that again to yourself. if you cut a hole in a box, put a room fan in the hole and turn it on, tada a pressurized chamber, although wouldnt be that much over atmosperic with a low power room fan. guys this is very practical, it just needs to be done correctly.

also, if i do get the chance to build this as a senior project, i would most likely use the compressor housing off of a turbo.

Or with a 12v electrical fan either. And pressurizing the positive boost system is what is needed. While I remain extremely sceptical (understatement) I say go for it and post your results.

>

well im only a freshman, and im not saying theres going to be some issues, but thats what engineering is about . main issue is power, highest amperage alternator ive seen is 300amp. at 12v output thats just around 4.8hp. im not sure whether or not that would be sufficient enough to run the compressor at desired boost. other ideas ive had would be a retro-fit system to install on a car to capture energy lost while braking. well see, its still a ways off. probably end up doing the sae race car or hpv.

im not saying electric isnt possible but no 12v fan contraption like this can possibly do anything.
ive seen REAL electric supercharges man. they have them already...... they cost close to 1k and you can only run them for 15 seconds. due to the motors heating up and not having enough current to power them.
and yes they use a compressor. like a pro charger setup just where the pully is they mount a high power motor.

heres the link of a real one http://www.turbomagazine.com/tech/0406tur_knight/

oh i agree with you that the eturbo on that 5g isnt doing much, if anything at all. and i remembr seeing that electric supercharger before, i dont know if a link to thomas knights page is in the article so electric supercharger. this setup is essentially the same thing im talking about except that it is not continuous. he calculated 450cfm at 8psi requires about 18-22hp. ill guestimate a 4-5 hp should be ok providing 3-5 psi on a 1.8engine whose cfm is around 191 cfm at 6000rpm. keep in mind it would provide a higher sustained boost at lower rpms until the compressor could no longer flow that much air.
