good luck but i doubt youll be successful. prove me wrong.

 

ok .. I wana see this . It certainly would have some advantages if you can make it work. I ve always wondered why there are no electric superchargers. question can you make the boost man?

 

you won't be able to get enough CFM to boost

unless you run it with a dedicated battery and only for a short amount of time (like nitrous)

 

You'll need an enormous electric motor and an even bigger alternator to feed it. Every time you convert energy you lose power and create heat. Converting mechanical to electrical back to mechanical is not smart. Your EE buddy should understand this. There is a reason superchargers are driven with a belt. Belts lose very little power. All the power you take away from the crank goes straight to the supercharger. With an electric unit, you're taking power to drive the motor, and even more power away from the crank trying to drive that 300amp alternator that'll you'll need.

I dunno. Maybe you could use battery power and only use boost at full throttle so you don't have to use a huge alternator. But then you might as well just get a nice multi-port nitrous system if you don't want "always-on" power.

Sounds like a neat science experiment, but you're not going to compete with a belt driven unit like RIPPS on cost or performance.

I enlisted a couple of geek friends of mine to install a computer fan in my CAI, now I am running 3 second 1/4 miles, it rocks!!!!
I hope your project works out well too.

Is your name Chris and do you live in Canada?

 

hahahaha 3 seconds must be that chris guy settin more world records

 

I am glad the reference wasn't missed! :3_winkthu

 

Thomas Knight has been producing electric superchargers for quite some time. They run in 15 second intervals, or "bursts". Take a look at his website, I'm sure it would help out some.

Actually, I remeber reading VW/Audi has a working electrical turbo charger that it is
planning to add to it next gen Audi TT.

A little more info for the curios...
Electric motor is 24-28 volt 15 amp. Variable speed, constant torque under load to 8000 RPM. 12 to 14 volt input, constant 24 volt output transformer, 35 amp draw. Controller circuit monitors RPM's and adjusts motor speed according to the settings selected in car. Vortech Supercharger, it produces enough cfm and psi in belt driven applications, why not with an electric drive? The motor has enough push to make 15 psi static pressure. When the engine is drawing volume in at an increasing rate the limiting factor becomes vent size and length. I'm not an idiot/mad scientist/moron. I design 20,000 to 120,000 dollar artificial limbs for a living and I love cars. If this works as well as I hope I can place the charger in a convenient place in the engine bay and not be concerned with the belt or shaft driven limitations on location. To those of you that flamed me... See you in my mirrors. To any one else that is mildly supportive. Keep your mind open and your pedal floored.
Thanks

 

hmm im skeptical about this, but you obviously know what ur doing. good luck

 

ive been trying to design something similar for a while in my spare time, and have ALOT of thoughts on it, howvever the funds arent availble for prototyping, so PM me if you want to share some ideas to help make it work

it's been proven that this system is similar to nitrous in that it only delivers power for a bit and then it costs to recharge or whatever, and is far more expensive than nitrous. bottom line: NOT WORTH IT.

if you think a couple electrical engineering buddies can do something that a corporation full of them can't, you are mistaken.

Electrical, mechanical, & computer engineers have been talked to. 2 physics phd's and a bunch of gearheads that build dragsters and race cars. I don't discredit the work of others, I look at what they've done and try to improve on it. I' m not using a constant maximum boost but a variable/adjustable boost based on rpm's. Thomas Knight is using 3 small motors at huge voltage, low amperage. Mine will (hopefully) be one larger motor at a reasonble voltage, higher amperage draw.

I hope it works out for you. One thing to keep in mind is that the Vortech/RIPP systems use a gear drive system that enables the compressor to spin upwards of 60,000 rpm. How are you going to get an 8000 rpm motor to spin the compressor to 60,000 rpm?

 

The dude thinks he is really smart and is going to spend 6 months trying to do something that in the end gives him minimal HP increase but enough so that he will think he has a victory. The truth of the matter is it will be less efficient than any traditional SC setup and will give less power. However then he will be able to say that he did it, he isn't looking for power he is looking to feel good about himself for accomplishing something he did on his own. If he was really out for power he would realize this is not the way to go. But let him go out and make him feel good about himself for spending time and money on a minimally helpful gadget. Good luck with you little science project.

 

Stop ripping on him just for trying something different...sure with what we have seen in the past his future looks dim with this endeavor, but come on cut him some slack...let's just make sure that he doesn't fall off the face of the earth like so many other people that vow to do things...

I want to see where he ends up on this.

The exact same way you make a car turning 6500rpm make the same supercharger turn at 60,000! Gearing! Same thing Vortech does. The source of the power has nothing to do with it. You could have a handcrank or a gerbil wheel driving it, doesn't matter. You'll just need a very powerful electric motor to turn at 8000rpm to make a supercharger turn at 60,000rpm with gearing.

This is great and all, but I still don't see the point when you'll never get past the fact that eletrical power is not the way to turn a supercharger due to the lack of technology in converting mechanical power to electrical and back in an efficient manner. You'll never get past that unless someone designs an alternator or generator that is much more efficient than those available now. There are better methods for always-on power (turbo, centrifugals, roots), and better methods for temporary power (nitrous).

There are definitely major breakthroughs heading our way in battery and electric motors due to the industry push in that direction, but when you've got a perfect power plant and a nearly lossless way to power something (by a belt and/or driveshaft and/or exhaust turbine), why start 10 steps behind trying to convert energy to electrical and back again? I'm not trying to be discouraging or say it isn't possible, but there are so many better ways to go about compressing an intake charge.

High voltage low current vs. low voltage high current is completely irrelevent in the grand scheme. Higher voltage does have the advantage of not needing such large wiring, but then you need a whole new high voltage charging system separate from your normal 12v system. Voltage vs. current is going to be determined by what motors you can get that meet your needs. The real problem lies in efficiency of total power, not nit-picks of high vs. low current.

Exactly, you hit the nail on the head. Short of finding a way to break the laws of thermodynamics this kid will only be able to make a less efficient verson of a centrifugal supercharger, where as going with a standard belt driven setup will probably be cheaper, more efficient, more powerfull, and lighter. Like I said before, he is more concerned with cool factor than power, which is fine, as long as he is able to realize that.

 

The advantages of having a workable Electric Supercharger system are many. A belt driven Supercharger has a boost curve that ramps up with engine RPM. A exhaust driven supercharger (turbo) has to deal with lag and hi-heat.
The technology may not exist today to have a truly efficient electric setup, but when it does, watch out. Think about it. Unlimited mounting options, a boost curve that can me modified on the fly to match RPM or have instant full PSI off the line.

 

Yes, definitely. Once electrical systems have advanced, an electric driven charger has lots of advantages. Mainly active control. But you can also control boost on blowers and turbos with wastegates, blow-off valves, clutches, and by-pass valves. These can also be actively controlled by a computer and a few solenoids.

There is a lot of control that is rarely explored with belt and exhaust driven systems, but you are correct, you can do even more with an electric motor, pretty much custom tailoring a boost curve or certain behavior. But I think it is all moot until someone comes up with a better generator system. I see electric drivetrains taking over as or before that happens.

 

You can do alot more with the stuff we have than most people do, because of money. There are lots of ways to control boost levels, and by computer no less, but the average user can't afford the control units. Which would be the same problem with and electric unit. Also regardless of how much technology we advance you will always loose power going from mechanical to electric back to mechanical, it is just how the world works. A straight connection doesn't loose as much power, and it never will, thats how physics works. I just don't buy into the electric supercharger, you are welcome to, but I know that it just doesn't work as efficiently as a direct mechanical connection. That is my point, it is less efficient, that is what I have said all along, I never said it was unusable, just that it was a waste of power, those concerned with making the most power will know to stay away, it really is as simple as that.

 

I am kind of surprised by all the attention this is getting. I have been working on this for a while and I was just hoping to get some feedback. Mr. kwikblu from new york, I am not in need of a self esteem hug. I had an idea and said why not? Never seen anything like it yet, could it work? There are several details about the system I'm leaving out for good reason. I have no way to protect my investment from some guy with a LOT of cash sitting around to take my idea and burn me and my help in the process. Not that this is just about money. I am not in this alone and some of the points mentioned by others are legitimate and true. We have tackled them. We are currently trying to debug the control mechanism. The motor and charger are capable of 15 psi static pressure. active pressure can't currently go above that but I assure you that the cfm capabilities far exceed what my car can use.
Thanks for tuning in.
If you have specific questions about this, ask I might be happy to answer.
