ever heard of them?

 

a billit hairdyer that starts at $2995?? WOW

 

I would have saved this post for April fools.
Typical ricer bait

lightweight batteries...please

 

no way anything electric powered such as that could force air into a throttle body fast enough to build up boost

 

I don't know, if designed properly, there's really no reason you couldn't have a functional and effective supercharger powered electrically. For being designed only to give short 15 sec bursts, though, it is quite expensive. You could get a lot of NOS refills for that. Concerns include: what happens to your A/F mixture during these short bursts? How is extra fuel being delivered as well (or does i just blow hard and run lean for 15 sec? Yikes.)? And how restrictive is the thing to your intake path when not in use?

 

real blowers run off your crank. How in the world are you going to get enough current to force enough air in there to create boost? You would need to have a flux capacitor with lightning striking to do anything

 

Looks like it's got three starter motors hooked up to it, probably with some serious gearing. I don't doubt with that kind of torque you could get that much CFM, assuming it's got a centrigual fan design, but the problem as I see it is the power required.

If it draws 15,000 watts as specified in the advertisement. That's 1250 amps, being pulled instantly. You'd need some serious deep cell batteries, cables and charging system. Otherwise you're going to constantly be replacing damaged batteries and melted cables.

Also assuming it flows 5.5PSI at 405CFM it's only going to flow around 4.8 PSI at max RPM for our engine assuming a volumetric efficiency of around 80%.

The boost curve is going to be opposite what we see with higher boost levels seen at lower RPM's and less boost at higher RPM's because it's a constant speed fan. You could do a lot better by just getting a standard SC or TC FI system.

 

Yeah, I agree. 15000W = 20hp which is on the low side of what you would need to drive a compressor but it is still possible. It does look like they have 3 motors and some serious gearing. It is possible to get some boost (5 psi) out of that thing but it would never be practical. The motors are heavy. Batteries that can provide that kind of juice are also heavy not to mention the strain put on your alternator to charge those suckers. Because of the high draw you will also need some major hardware to make everything work=more weight. On top of that, if you think about it, this system is highly inefficient compare to TC or even SC. You need to convert mechanical power into electrical (juice for batteries), store that electrical power, convert it back to mechanical (batteries to motor), convert it again (step up motor speed to get enough CFM) and finally do the actual compressing of air. On the second thought maybe 15000 watts is not enough?

All that for a 15 sec burst??? Forget SC or TC. You can do a lot better with a nitrous bottle!

On the plus side, you can almost claim that you have the first 350z hybrid!!!

Personally, the only battery that goes in my car is the one that I need to start the sucker.

This is the perfect tie-in with the other electric supercharger thread:

https://my350z.com/forum/showthread....threadid=11625

This shows how far you have to go to make the electric supercharger concept (marginally) viable. By the time you get to the point where you are making a useful amount of boost, you only get 15 seconds of it, and now the thing is "starting at" (we all know what that means) three grand instead of $600. Notice that it's a pump and not a fan in case you missed that point in the other thread.

So now you've got your $3k electric supercharger. You need a better battery, beefier cables, etc. just to spool the thing up ($$$). Oh wait, you've got to get extra fuel to your engine as well ($$$). Plus, now you're at a compression level such that you really should have an intercooler to squeeze more efficiency out of the system ($$$$). Now you've got 4k in a system that is inefficient, useful only in bursts, and only gives you marginal boost anyway. Oh, and does your air have to flow through this thing when it's not on???

The whole point to people posting about these electric superchargers was the (sadly flawed) idea that you could get a bit of added hp for CHEAP. What's the point now?

Get a friggin' regular supercharger or a turbo setup. There is no choice. If you want short bursts only, get a bottle.

I hate to have to be the one to say this, but after 15 years of trying to make cars faster I know one thing and one thing for sure. You can't make significant power gains without spending a proportional amount of money!!!!

 

I have heard of this thomas kight before. Let's say I did not hear anything good about him.
