Ok I am working on a project that seems promising. Using the awesome mind of Rev hammer for assistance, but seriously looking into setting up an Electric Turbo Charge system for the 5.7 Hemi.
Using my car as the guinea pig naturally.
What is planned is installing up to 5 PSI electric system into the CAI.
Then, having a switch installed inside to turn it on or off when needed.
Most electric system, run from 6 volt through 25 volt.
Most come with a pellet chip that can installed to the A/F sensor.
Most claim they will not harm the engine. (Im thinking about the #1 piston exploding like when you run the GSM Supercharger) Yikes, that would be a bad thing as Martha Stewart might say if she ever got grease on her anti-bacterialized soap hands.
Most claim they can boost REALISTICALLY from 15hp up to 45hp. Though I have seen some claim as much as 200hp, im being real here.
I can see this working with a 5.7 if the P.S.I. stays under 5p.s.i. One unit made in England turbos at 25,000 rpm creating about that. Its mainly designed for engines UP TO 5.1 litres. So not sure about that one as Im in talks with the company.
Anyway, keep your fingers crossed, and put in your feedback for this project. Oh and I mean SERIOUS feedback as I want to eventually keep this thread sticky as a source of progress and maybe submittal to the How to section, if you guys dont mind.
I think it will take a big fan to pump air into a 5.7 at 5psi at full throttle.
Be interesting to see

From what I've read and seen tested, to create any type of actual boost, from an electric turbo, you'd need some heafty improvments in the electrical system to handle the amperage being drawn from the turbo. Otherwise the natural suction from the intake would be greater then the turbo produces, thus actually hindering performance. If you can get it to work and it not be a modified leaf blower, go for it.

I assume you've looked at Mark Kibort's electric supercharger? The e-ram? Its a hi quality unit but its effectiveness has been debated in other circles endlessly; notably the Rennlist (Porsche) discussion lists although i think the topic was banned eventually. Most discussions focus on all of the amps that you have to pump thru your electrical system to run your blower of choice. Kibort himself states the 5.7 hemi needs two of his units running inline to produce sufficient boost to achieve results.
I have a sneaking suspicion the Rev has something innovative and interesting to add to this subject.

I just wunna know why?!?!?!
Just answer why?!?!?
We can barely figure out the easy stuff.......and the stuff we have figured out, it just starting to pay off........now an electric turbo / blower?
I just don't get it......
Sorry........I wish you luck but I can't help with electric stuff.....
Ok I agree with PowerWagon that it will probably take about 500CFM to break even, so the goal is to exceed that much without going over 5 PCI so no pistons are blown.
I agree that amperage may need to be supplemented. An additional remote power source maybe?
The unit can be turned on and off so used only when needed.
I DONT think it will require two turbos to accomplish this.
Moms RT, because with a little here and a little there by many people, we can create a whole realm of options in a shorter span of time. Remember, we are playing catchup to the Mustangs, Vettes and Rice-A-Roni. They have had their codes broken, aftermarket parts created, etc. Chargers have few options as of now. Rather than wait until the 2009 model rolls out to finally have some decent aftermarket options, I would be more inclined like others, to accomplish this before next racing season. Which is about 6 months from now possibly sooner depending upon the winter.
Any debate over the amount of air to move is not important. The project is not about the supercharger itself, you can just use the one of your choice, novi, whipple, etc.
You still have handle the fuel managemnt just as with ay other forced induction system.
Therefore, the only new issue is powering the SC. A 1.5 HP electric motor will do that easily. You may need some extra batteries and you may need to run a 24 Volt system. You will also need some electronics to control the motor, but that is pretty much off the shelf stuff.
Thus, the question is not can it be done, as it can. The real question to address is why this is a better solution than the conventional SC or TC approach.
I would think electric vs. SC is not belts or other issues running full time.
With electric you can turn it on or off at will which in the long run would not be harmful to the engine.
Having done custom turbos myself, I would honestly have to say this undertaking is bigger then you guys think. Sure the idea has been around for ages, and it has even been "somewhat" accomplished. However- the sole premise behind your reasoning (to be able to turn it on and off), will be your biggest stumbling block.
Getting the +psi is the easy part. Computer and engine management is the tough part. We are barely able to tap into our computers now for mild tuning, Now- with your idea- you want to be able to not only tap into your computer to control things like a/f ratio's, map pressures, and voltage, but you have to somehow be able to tell the computer when to do this and when not to. If you don't do that- your will be running rich when the "turbo" is off, and could run lean when it is on. The dynamics of this tune would have to be perfectly set in order to pull it off. I just don't see it happening.
It can cost an arm and a leg to control your settings for a full time turbo/ s/c application. Now try to control it stock to turbo on the fly. For something like this, I would think you would need some serious financial backing and production resources in order to just see if it were possible.
I seriously back you guys for the desire to be innovative, but this is one project I wouldn't back personnally.
Good luck to you though.

You should try powering the fan with an aftermarket "flux-capacitor", that extra 1.21 jigawatts should turn just about any fan pretty nicely...
Seriously, electric fans don't work. You could spend your time, energy, and money on a much more proven technology, and actually see some results...
Was that too negative?? I am feeling a little cranky this evening....
There is no question that an electric moter can run a supercharger. That is just rpm's and power. Once you have that done then you still have to solve all of the problems you have with a belt driven supercharger.
Then you have to answer the question - Why is an electric drive a better solution?
I agree.There is no question that an electric moter can run a supercharger.
But is it a good solution for task at at hand ? No.
It would require the installation of a relatively high current, circuit and control system. The instantaneous current requirements would be higher than the engine starter. Unfortunately the speed at which the motor is turned would have to be very closely controlled, in order to keep the boost constant relative to engine speed. All of this is effectively handled by a belt driven supercharger since it is directly linked. The amount of electronics required to properly drive the electric motor powered supercharger would be staggering. The electronics would also generate an enormous amount of heat and generate a great deal of electrical noise. The resulting technology would be expensive and very dangerous to work on.
My previous comment on the electric supercharger not working was addressing a reoccuring thread that seems to keep getting restarted in all of the car boards about a crappy little electric motor with a fan in it
like this one:
They truly do not work....
I'll shut up now.
