Has anybody seen an electric supercharger on a 350z?
I found one on ebay http://cgi.ebay.com/ebaymotors/ws/eB...tem=2459571294

and at
www.electricsupercharger.com

Do you guys think that it worth it?

 

Watch out here come the replies !!!!

 

here come the replies is right. are you actually serious? if you want home depot is having a sale on leaf blowers. i plea to the gods of superchargers do not get that. i have seen the e-charger before and um yeah it did absolutly jack s$#@ for the guys car.


ha wait a minute was'nt this same thing on the board about two months ago. yeah it was, i still have puke on my key board.


ha seriously thow, dont waste the money ,bank it for the real deal. the so called e-charger is crap.


my .02

 

hell no, do it right, spend twice that amount and get nitrous..........the only electric supercharger i have ever seen that even makes alittle sense cost almost ($3,000.00) as much as a real supercharger. You get what you pay for. HP is not cheap and never will be unless of couse you get nitrous oxide. Best bang for the buck by far.

 

I know that it's not a replacement for a turbo, supercharger or nitro but as a nice add on to a CAI.

 

It's true they are quite expensive from what I've read on them.

 

It's just an electric ram air not a "supercharger". Good idea,not bad price, might be worth a try.

 

I know that it's not a replacement for a turbo, supercharger or nitro but as a nice add on to a CAI.

 

The most expensive product is the eRAM-S-3.0-KN for $629.
I was thinking about the one for$299 to add to my CAI.

 

Save your money. That stuff DOES NOT work. Its a rip off. Go on google and type in electric supercharger and just see for yourself.

 

Well, I checked google and I found just as much good info as bad info for the electric "supercharger".
Reminds me of the CAI debate: "CAI's only gives you 3 to 4 more hp. It doesn't work. Save your money. Its not worth it".

 

On the positive side, electric motor powered turbos are on the horizon, cars are about ready to switch over to a 24v system, with that we will see the end of hydrolic brakes, introduce drive by wire.

Ive read cool things about AMG puting out an electric turbo for thier cars, talk about true FREE horsepower!!

 

I've heard rumors about the us spec skyline gtr using this type of device to aid turbos in spooling. Only time will tell...

 

There is no such thing as free horsepower.

Where do you think the f-ing electricity comes from to run this thing???

Some turbocharged engines do have electric motors to spool the turbo up when the engine is at low RPM, reducing turbo lag. This is the only feasible/effective use of this application. It is an electric motor spinning a proper turbocharger as well, not a little fan like this product has.

 

I just had to go back and dig out my old electric supercharger posts:

On the general concept:
In response to the major agrument, "what is a supercharger but a big fan": a supercharger is indeed not a fan. It is a PUMP. A pump is used to transport a fluid (yes, air is a fluid) with a significant pressure differential across the device. Think about it this way: you wouldn't try to fill the tank on your air compressor with a fan -- you'd never get squat for pressure because it would (basically) just blow back through the fan. Pressure is force divided by area (psi=pounds/square inch). That is, the maximum pressure you could achieve in the tank would be equal to the force the fan puts out times the cross-sectional area of the orifice you're blowing through. In laymen's terms, for a fan this ain't much.

Don't pay so much attention to the cfm's these fans can flow -- cfm is volume per unit of time (cubic feet per minute). Pressure is not in the equation at all. It is possible to move huge volumes at low pressure (ever heard of HVLP automotive paint systems?).

Another little point is that there is no such thing as energy for free. Why don't you run your power steering pump, a/c, water pump, etc. electrically instead of robbing all that precious power from your crankshaft? Because you'd need such a big-a$$ alternator to do it all that your overall system would be less efficient than when you started. In use, alternators don't just free spin like when they're in your hand. There is mechanical drag as you convert mechanical energy into electrical energy. There are also losses associated with this transformation, as well as with the subsequent transformation back to mechanical energy (via an electric motor). It robs more horsepower from your engine to generate enough electricity to run your accessories electrically than it would to just run them directly.


And for the $3000 one:
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!!!!

 

ok, thanks for the rude reply , guess you need a tiny lesson on paracitic loss. Every device on your car; ac, alternator, belt driven supercharger, ect... sucks precious horsepower away from the motor. Example, car has 250 RWHP, you bolt on a supercharger, it costs you 20hp to turn the turbine on the supercharge, your down to 230 rwhp but the supercharger adds 100hp, for a net hp rating of 330. Turbos have been called free hp before but the exhaust backpressure and less than ideal headers still put a small penalty on them.

When I said free horsepower I wasnt talking about money, I was talking about FREE of paracitic loss. In 10 years we will have cars that just thru materials and technology alone will need less power to outperform/accelrate our current beloved Z. Its the exact reason why nissan went with a carbon fiber drive shaft instead of another material ect..

Now if they change the charging system to 24V there will be enough power to run an electric turbo, then without adding any more parasitic loss (ie gear drivien superchargers, extra resistance from the alternator, exhaust backpressure from turbo) then the horsepower gain in fact is free. The advent of 24v is just over the horizon, the benz has already commited to this and all car makers are soon to follow with all the incar electronic goodness that is being packed in all cars.

 

I apologize if I sounded rude -- I didn't mean to. I just get aggrivated by all of the "miracle products" that so many people fall for and get taken by some scam artist.

Yes, I understand parasitic loss. That's what half my post was about. I know you didn't mean free money-wise as well.

I too am looking forward to the widespread adoption of higher-voltage electrical systems. They will revolutionize the way our cars work. I'm still skeptical that you'll be able to run an electrical supercharger with less losses than running it mechanically though. I'll have to run some numbers...and I may be just big enough of a dork to do it.

 

Well I just happend to see a cool concept from mercedes at a dealer trade show, this sucker had electric turbos (I think it would be more aptly named supercharger the way they work /shrug) electric brake calipers (new sl has that backed up by hydrolic lines) for WAY more traction control, electric drive by wire. The head on the car had an electric actuator to change the compression on the motor on the fly (they since sold the patent to saab I think it is that is planing on using it on an upcoming car.

Basicly the turbos looked like your run of the mill turbos but instead of an exhaust intake a motor was attached to the turbine itself, the reason for the concept was to highlight the possiblities of 24v systems, the car was passed off as a working prototype also. Ahhh the future is bright for car nuts

 

That's freakin' sweet sounding. I think it was indeed a Saab that had the helper motor on the turbocharger as well. Who woulda thunk that GM would be savvy to such things.

 

Has anyone actually tried this?

It is still on Ebay: http://cgi.ebay.com/ebaymotors/ws/eB...spagename=WDVW

How long of an extension cord do you need?
