Electric turbo
Discussion
domster said: The whole point of a turbo is 'something for nothing', anyway. ie all those exhaust gasses get put to good use. If you have to put energy in, might as well be with a supercharger belt driven off the engine.
Maybe an elastic band powered turbo would be good, or get a few hamsters in the back spinning up the turbineI can see it now, the Volvo S40 HamsterTurbo
Otherwise, what about a big bottle of compressed air? You know, diver's bottle. Assuming weight wasn't a problem it could give you A LOT of boost for a limited periodie the energy is put into the charge beforehand. If you're doing bottles, makes as much sense to go for NOs, though, eh?

Maybe what you could do then is to have a passenger continuously pumping up the air system (using a bicycle pump). This could be released under full throttle. MPV's would then be the fastest things around, as you could have say 6 passengers pumping away as you drive, which would generate massive boost & power. Although I'm not sure of the legal standing on having 6 people pumping away in your car while your driving....
You dont get something for nothing with a turbo.
You get increased backpressure as a result of impeding the flow out of the manifold.It takes boost to simply drive that extra gas out.
Come to think of it, i dont reckon you get anything anywhere for nothing... theres always some sort of trade off, whatever system you use.
The electric one is quite interesting tho, you get the chance to have turbo-like performance, and supercharger performance, without any of the drawbacks of either, ie; the heated intake charge etc... and the power losses associated with a belt driven supercharger.

Pelo said: Well it worked on my lawnmower
I got my sisters old hairdryer, removed the heating element, wired up a potentiometer to vary the hairdryers speed, took off the air filter assembly, put a pvc funnel onto the carburettor, and sat the hairdryer in it.
Start up the mower, flick the switch, turn the knob and BOOOOOST! Simply twisting the knob was like instant throttle. Imagine this on a gokart!
The motor was never the same again
The mains, unfortunately
As someone already aluded(sp?) to you need to increase the size of the alternator and run the cars electrics at a higher voltage. These are both things that are looking like they are going to happen soon anyway though, 42V cars and combined starter alternators are already in development. Electrically Assisted Turbocharging is deffo going to happen soon, I very nearly started doing a PhD in it last september but funding fell through.

What a load of horse poo. You can spot this rubbish a mile off by the riduculous terminology they use:
"The Turbo Jet. One of the greatest innovations in air velocity technology."
Air velocity technology? It rests in the same pile of excrement that molecular spin inducing magnets, and the turbulence creating air bleed valves belong. It never ceases to amaze me how many benefits these paperweights seem to achieve:
More power
Better "throttle response"
Lower emmisions
Better mileage
Less engine wear
You name it, our product does it...
What also makes me laugh is the zeal with which the guilible rush to the products' defense under the inevitable barage of scepticism by the cluefull. A zeal fuelled, no doubt, by the gradual dawning that they have been suckered in by the techno mumble.

I like the bit..."please note, We must say that this product will not give your engine hardly any BHP gains but will definitely assist you in accelerating from standstill to point to point quicker than before."
If it doesn't give any power gain then how can it propell your car any faster??

There is actually an electric turbo on the market.
Cant remember who its made by at the moment tho, but it fits most cars and gives a modest 15% power increase on a standard unmodded motor.
The test car was if i remember correctly a mitsubishi charisma...supposed to be a part replacement fitted in the airbox..talk bout stealth!
Would this be the one?
www.electricsupercharger.com/
Just been searching the topics here for electric superchargers and I am really intrigued by this thing, I can't work out whether there would be any gain whatsoever in the power of your engine.
If it only comes on at full throttle it could effectively run from the battery which would be recharged over the rest of the journey. So, the overall energy used might be more than it produces but you still get that little bit of extra performance at full throttle. Or do you? Confusing.
Anyone tried it? Antone properly understand it?
Electric turbo chargers do exist i believe garret and a few other companies already have at least prototypes.
Yes they will probably require a 42v system to work at their best.
but just think, the electric will only need to be on for a very short period of time i.e. from the point where your pedal hits the floor to the point where the engine is generating enough boost through exhaust gas, the electric will also amplify this effect. Think how long your starter motor runs for?!
Another advantage is you can use the motor as a generator and waste gate in one, apply load to the motor and this will restrict the rotation velocity of the turbo (hate to think of the forces but it theoretically could work). increasing flow capabilities and efficiency, you could use a smaller turbo to do the same job.

Think I'm confusing the issue here between superchargers and turbochargers. Ah, the topic title is for 'turbos', sorry I'm thinking about superchargers as described in the link in my prev post.
The supercharger unit works on the induction side of the engine only blowing more air into the carb without being driven by the exhaust gas like a turbo.
So giving initial pressure for a turbo aside, what about the claims for just using the electric supercharger on the inlet at full throttle?
Hmmm.

Tell you what works better ... Off topic, but more fun.
Get a Butane can, Tap a small nozle into the inlet manifold of the lawn mower ... turn on the gas and run the Mower ..... Its not Nitrous, but it doesnt half go !
Hmmm, this looks interesting, theory is sound and if its built how they say it would indeed give a reasonable amount of boost.

Only problem is you'll have trouble keeping up with it, bloody grass cutting gives me a sweat let alone at 40mph!

California Poly Pomona University had an electric supercharger on their 2000 Formula SAE car.
It was f*****g awesome!
