I=p/e

=900w/14v
=64.28A

I'm gonna say it's more like 64A because the battery will read 14v when the alternator is running.

I looked on a website and it claimed to draw 57A.
It also said you could not run it more than 30seconds at a time or you risk a failure condition.

Doubt this thing is good, I bet a 65 degree morning is better for performance!!!

 

I've seen articles on rear mounted turbos that spin a generator or an absorber that charges lithium ion batteries which in turn powers an electric supercharger. It's nothing new, transferring energy through electricity is more efficient than belts or air through piping (mechanical force). Look at the use of electric power steering and electric radiator fans in modern cars. The amount of btus or energy stored in a lb of gasoline vs the energy produced by the internal combustion engine is key. The exhaust is where you can recycle and reuse the the lost energy via mechanical and heat energy. And don't forget, superchargers have a multiplying effect on horse power. Don't know about this product though?

hey!

 

your humble about it though this dude is just a tool

It only engages at wot via micro switch on the throttle, like nitrous.
Ohms law states amp x volts = watts or work being done
So they have a 50 amp relay and the motor draws 65.916 amps?
791 watt motor divided by 12 volts equals 65.916 amps?

I wonder if they could get more gains with a slight tune?
A larger alternator, a couple more batteries (placed in the rear for weight distribution) and a stronger axial motor, and a retune. I could see 4 or 5 psi boost at wot for relatively cheap and simple setup.

 

Ok, 57 amps in "free air". A V8 at wot sucks roughly 400 cfm, the axial fan produces 800 cfm "free air". So with the discharge side of the fan in a negative pressure it's safe to assume the fan motor is working less hence the 50 amp relay.(I know I messed up in my previous post stating 12v, should have said 14.4v. Even though that still puts you at 54.9amps)

I would like to see if there is a temperature rise across the electric motor, calculate the physical work being done and subtract the amp daw, convert the answer to btus and add that to your intake temp. Then calculate how many more hp your alternator is robbing at wot and low rpm since alternator performance is limited by rpm or put it on the dyno http://www.electricsupercharger.com/...no-article.pdf

Hmmm interesting, ultimately your limited by injector and fuel flow restrictions as far as boost psi. But it's still cheaper and more reliable than say a stage 1 supercharger or turbo

 

All that and you're a douche. Amazing.

 

Now, who is willing to move forward and add 2 of those superchargers for 2*$200 = $400 on VQ35HR? Some dyno charts could be helpful

good luck

 

I mean really? Is it worth it when you consider the extra drain on the engine with the alternator working overtime? You would only gain about 5hp. I am just trying to figure out the benefits vs the loses here. IT is a nice concept, I just do not think it is worth anyone's time. I think there needs a company out there that is in place to keep dumb ideas off of the market. This is a waste of time and money....They want $200 for something that could potentially hurt my engine?

 

Dat shyt dont improve HP.. it decreases it..lmfao

 

 

Please keep your arguments to the subject matter, not the person.

 

 

Is the power needed to reach 1 PSI linear - so that 2 PSI is twice the required amount of energy? And would it stay linear?

That E-charger reaches 1 PSI @ 25,000 rpms with that fan. 5 PSI would require 125,000 rpms if the output is linear.

I see that its def possible but the gains don't quite look there.
