Topic: Electric Tubos/Superchargers

[DarkSlySol]

I need some info from some turbo or supercharger experts lol, I stumbled across these things called Electric Superchargers/Turbos. They claim 2psi boost and I believe a 20%HP increase which I ALREADY know wouldn't be possible for a blower running off of 6amps, no need to tell me that lol. But I do know the concept is doable with such force inductors such as the eRams. The eRams run off of 60amps and they claim a 5%HP increase but not sure on the boost tho, which seems more probable and has been proven to work. There's a couple things i would like to know:
1)To increase power, do u need to increase the volume, the pressure, or bo th?
2) And if you jus need to increase the volume would the product work?(not nessecarily how much they claim, but wouldnt it increase the volume?
2) What is the volume of air and/or pressure the does the stock air box produce?
3) How much volume of air and/or pressure would a 6amp blower produce?
4) So what is the  minimum amount of amps needed to achieve at least some sort of gain?

In answer to 1) & 2) - The goal is to increase the volume (more accurately the MASS) of air getting into the motor.
The sensors & ECU will mix in the right amount of fuel so the correct AFR is present.
More Air + More Fuel == More Power.

This can work, but most of the products you'll find are cr@p.

The only ones that really work are probably the one from Thomas Knight.  They are a supercharger that is run up to speed by something like 3 Heavy Duty electric motors.

Leaf blower will work, but the extension cord is a BEATCHE

Humm if we can come up with some technology to solve that problem we can share it with:

Don't forget that carrot on a stick or the parsnip that those Scott's had on Ebay a month ago.  That is definitely "going green."

I think I will develop the electric car that has no battery just a long extension cord.  I'll practical give the cars away but make it use a special cord and make my money selling the cord to people that want to drive like more then 50 ft. Maybe the oil companies will feel so threatened that they will give me vast sums of money to keep my corded car off the streets.  Anyone care to invest in this business plan?

That would suck up a lot of juice wouldn't it?

[DarkSlySol]

ok now bare with me lol, so based on the fact that more airflow and fuel  wud gain more power, wouldnt the little blower work in theory jus based on those facts? (not nessecairly the increases the seller claims)

interesting tech, good for track, not so good for a street car.
The motors draw serious power - they do not even attempt to run it off the alternator.
Works more like nitro than a supercharger.
Interesting read though:
Their website:
http://www.boosthead.com/product.php
and a review:
http://www.turbomagazine.com/tech/0406tur_knight_turbo_electric_supercharger/index.html
(which also contains some interesting history of the invention)

(I am probably getting close to the edge of my ability to explain this stuff - IANAE - not even close I do software)
The 'little blower' would have to be able to move sufficient air (CFM) against the pressure buildup (BOOST) in the intake manifold.

To make this work a carefully crafted fan blade (that can BOTH move the required CFM AND continue to push the air against the back-pressure generated as that volume of air gets compressed into the closed space of the intake manifold between intake strokes) is required along with enough power to turn the blades fast enough is required.
Being able to do that is what requires all the power.

One of the interesting tidbits in the second article I picked out was the fact that Thomas's first successful version was using a roots style supercharger. These are NOT fans, but instead is a "constant volume positive displacement air pump". When it turns 1 rev it WILL move a fixed volume of air against (almost) any back-pressure (if you have the power to turn it). I was surprised to see on their website that they are also selling centerfugal turbos (like the Redline/GXP have) too. A centerfugal turbo will just consume power and spin generating heat w/o increasing pressure when the back-pressure exceeds what it can handle.

I cannot figure out what the wiring on those batteries is doing. Follow the clear wires - two wires per terminal, three cables leaving?? WTF? Pulling off several voltages? Are there more wires  in that bundle than I think?

[tazz]

There's more to it than that just kinda posting that it does take alot of juice to power the supercharger.  Best bet is go to the website and do some reading which I thought most would do anyway.  Just google Thomas Knight electric supercharger and do some reading on the workings.  
Looks like you posted the link to the website it should have explained some of your ?'s.

I posted the links but did not have question about how much power it would take (already read the sites).
(If I misinterpreted you and you were referring to someone else - just ignore this  )

I think I have this one figured out.  A gas generator in the trunk should do the trick.

Its kind of hard to tell what they are doing with those batteries in the picture, it could be they have 3 separate circuits, one for each of the motors or it could be they have it set up so that a simple switch will give you three different voltages.

Centrifugal pump wheels can generate a lot of air flow and pressure.  Early turbine engines all used a centrifugal fan, there is a lot more pressure in one of those engines then you will ever see in the intake of a recip engine.

I was confused by the second wire at each terminal - just weird.
If we're going through all that trouble go straight to electric - more torque than you'll know what to do with then!

[Sol Asylum]

You will also need more then three batteries though.

Why not just bolt one of these babies to the intake?

http://www.husqvarna.com/us/landscape-and-groundcare/products/blowers/180bf/

I can vouch for the fact that it will move enough air.

The fact that it runs out of gas after about an hour of use might be a problem...

Hummm, I have one of those,.... hummmm.

No. That would be just wrong.
  

not to mention the other kappas at the dragon would make fun of me! 

[Bigblau]

This is too funny.

Nice concept, but IMO all this electric stuff is for the birds.  Just get on the bottle ...you could also have a few shots just for some laughs.

Hummm, with all that laughing you should check to ensure you don't have a leak in your nitrous bottle...

Or do what has proven time and time again to work:  a real crankshaft driven supercharger, or an exhaust gas driven turbocharger. 

I saw this exact same thread four years ago on the Mustang forums.  The consensus then was that its a gimmick -- like Billy Mays or the Shamwow guy.  But maybe the technology has advanced since then.

But even on a 2 liter motor, an electric powered fan would have to move and compress an assload of air to generate and maintain positive pressure to create boost.  Not sure it could be done with a stock electrical system.

The Knight system flagged by Nomead seems to be the most promising technology --

Electric H20 pumps and power steering pumps, on the other hand, really do work, but they do not have to do the work of forced induction, and a normal electrical system can handle the load they require without a lot of messing about.

There are no shortcuts or free lunches in life.  If it sounds too good to be true, it is.  My verdict -- Interesting, but not quite there yet. 

Call DDM and be done.

[kennysabarese]

what about compressed air? it would be cheaper than NOS

[Critterman]

  What the guy that doesn't exist said 

[nomead]

This started off serious, but I think we all reached that same conclusion several posts ago and were just continuing to laugh at the possibilities

I hope the original posters actual question was answered - which is IMHO yeah, this is possible, but not practical.
