I was wondering if anyone has actually tried an electric turbo before.. i mean literally.. has anyone actualy tried it?? i believe all it would be doing is giving a huge amount of air intake action.. i am considering doing this.. because hell, if it does give off "650 cfm" thats like 3-5 lbs.... still a nice boost.. and you can control it.. so.. who knows..

That brings up a rediculous idea I had once. Most turbos spool up at around 3500 RPM because the exhaust gasses are only strong enough to fully spool up the turbo at that RPM. That's where turbo lag comes from. Why not modify a turbo to have a electric motor of some sort start spooling as soon as the accelerator is pressed and the throttle opens and let the exhaust gasses take over at 3500 RPM and elimate turbo lag.

Forgive me if this makes no sense, because it probably doesn't.

I posted a similar question in the turbo area just a few days ago. There is a way overpriced electric supercharger you can buy that makes a whopping 1 psi. and promises 5-15hp gains, woo hoo!

Well actually.. i found at a hardware store, a turbine compressor for piping, and its 20 bucks.. it runs on 12V so i am thinking its 3" diamater.. i got an idea.. but i need time to plan...

Now for $20 that's another story. If you can make 1 psi and get 5-15 hp gain from it then that'd something. Let us know how it goes. I'd be willing to use my car as a guinea pig if you can find out who makes that turbine compressor, is the hardware store a chain? What are of the store did you find it in? I'll give it a try as well. Does it say what flows at, how many CFM? It'd have to be a lot since that electric supercharger flows 750 cfm and only makes 1psi boost.

hmmmm.. there mus..

hmm.. there must be a scam goin on then.. cause on EBay they have "electronic supercharger" blah blah, and they claim that it pushes out 600CFM.. and a T-3 turbo "they say" pushes only 650 cm.. so prepare for 40 hp gains!!!!!

It goes on EGay for like 250... and it is at home depot.

Check it out.. i will on my next day off.. i could be mistaken about the price though...

Flow is not everything though. It has to maintain that flow while pressurizing. A T-3 will flow at high cfm while pressurizing. So you say this turbine compressor is at Home Depot eh? It's for piping, as in like I'd find it in the plumbing or HVAC sections? (assuming it's used for plumbing vents or for inducing draft) I have tuesday and wednesday off so I'm likely to go take a look at it. Even if it only pressurizes to 1 psi if you can get even 5hp out of it, it would be worth doing.

where exactly would this elecrtic turbo be connecting to the engine?

I'm guessing it'd be before the MAF and before your filter box if you still have the OEM intake. Or after your cone filter and before your MAF on a CAI. If you have a WAI you might hook it right up to the MAF and then hook your filter to the fan. If we were to base this on typical turbo setups, we'd put it after the MAF but I don't think it's going to build enough pressure that the MAF wouldn't perform correctly, so putting it before the MAF shouldn't be an issue. But this is more like a supercharger than a turbo since the exhaust isn't doing the work. If the fan is only $20, I'll buy several and see if that makes a difference. If it doesn't do a damn thing, I'll return them.

I'm inclined to think it's going to help some, simply because it's like a forced ram intake. If ram air works, this will work also. How well it'll work is the more pertinent question. Controlling the fans will be easy, on the Electric $upercharger setup that you can buy, they say the fans only turn on at full throttle. So it'd be easy to make that happen. Either using your TPS or go the safer route and just mount a normally open switch that will only operate when your pedal is floored. I looked at those motors that guy is selling on e-bay. It's funny, he's got the same motor for sale for a bunch of different cars and the prices vary! Smart guy, wish I'd a thought of it.

hhaha yea..

hahah, well they told me it was an exaust fume fan, and its used for like.. ventalation.. so i am thinking of getting on right before the MAF, and after the cone filter... maybe making a little CAI action even?...

Im just going to get a variable switch.. like a toggle twisty switch.. turn the switc knob and it will go faster, and turn the switch on the power the fan... thats my idea.

I think that i will do nothing.

The idea is realy good and I was thinking about to build one some time ago. But you will need a large turbine and a strong electric motor and a second alternator to deliver that amount off current you will need. Then you will need a PWM amplifire and a rev meter to control the turbine speed(boost). I failed on the turbine.

Think logically now, these pieces of junk have been out there forever, and nobody has them, why you ask? Because they don't work! It's not worth even discussing.

haha.. i agree..

ahha, i agree..sadly itwould take toomuch $ for a ghetto Turbo.. compared to just gettin a damn turbo

u will cause so much drain on your alternator and battery this wont help u at all

Maybe that's why they engineer forced indution solutions specifically for cars. Probably because hardware store parts don't work. What a concept.

I actually thought of trying that with this electric leaf blower that the previous owner of my house left in the garage.

LOL!

Yeah, just like making your own CAI out of things you can buy at the hardware store is stupid, it only works the same and saves you $150. What a concept indeed.

I think you know where you can stick your damn cynicism. Fact remains, the only reason that this idea is likely to fail, isn't because it doesn't come from an auto aftermarket company with a sticker in the box so you can stick it on your car like a fucking tool. It's because, as I mentioned, although the electric motor might flow enough, it likely won't pressurize enough to make it worth it. We run into shitty attitudes like yours all the time over at the sr20deforum. People crap on someones idea and then when it works, they're humping the guy's leg, begging to know how to do it, or throwing money his way to make one for them. I wouldn't expect it to work wonders, but that doesn't mean someone shouldn't try it. It might work enough that it was worth doing, it might not. But trying it would be worth far more than bad mouthing it and not having learned anything.

I don't understand why you're comparing making a CAI to a turbo/supercharger system with a hardware store electric motor. By the same token, why not make your own wheels? Or tires?

sorry, I'm going to have to go with Scott on this one, you're comparing apples to oranges.

the electric turbo won't work that well, if you manage to gain anything, you won't accomplish more than the "electric supercharger".

Back to the basics, a turbo works off of the engine's wasted power, making a turbo an efficient boosting application. The concept of using an electric turbo it means taking energy FROM the engine (the alternator) and applying it to give the engine such minimal boost, that it's not worth it. Besides we're talking about an electric motor about 3" in diameter (the blades) pumping air into an engine off of 12volts.

The leaf blower is a neat thing, but you would need a pretty long extention cord. and don't say power inverter, b/c once again, thet robs the engine of power.
