What is that object connected to the intake?

 

[RichAwesome]

I believe that is the electric supercharger.

 

[krotch]

Yep, that's the electric supercharge. It's awesome. It gives you all of 0 hp.

 

[Skidd]

Yep, that's the electric supercharge. It's awesome. It gives you all of -15 hp.

fixed

 

[krotch]

I have no idea how much it actually takes. The power gain is negated by it's power draw. But is the power drawn more than the power gain?

I think about the only way to make gains with an electric supercharger is to make it more like NOS. Have some capacitors that slowly pull power from the engine. During times like coasting along the highway. Then you can release all that power into a fast turbine to actually compress air and generate a good amount of hp increase. Of course, the capacitors would drain hella fast and you've be back to normal hp in a matter of seconds.

I think (after posting a thread dedicated to this topic) that the only way to get a true benefit from an electrical supercharger would be to only use it to keep the intake manifold from going in to the -psi.

I mean even +.124566 psi would have a small benefit, anything keeping the intake from going in to the negative pressure range is going to have a positive affect on performance.

Granted you wouldn't see 20hp but you might see 5.

Hooked up a variable speed motor with an impeller, controlled with a linear taper potentiometer and you have yourself something that might work. Worth your time? Maybe, worth the effort? If you're not busy, interesting and unique hell yes!

 

[krotch]

The problem is, the power it's drawing from the engine. If it can't make up for it, then it's pointless.

meh, it wouldn't take much to move more than 300cfm or is it 300fmhr?
But what you say is true, if you aren't going to get a decent gain why even do it.

 

[krotch]

I wonder if he got any gains from anything he even did to it.

 

[ballitch]

I have been tempted for years to buy one of these and make it work, just to say "HA, see, I told you it would work".

Then I snap back to the real world and continue on my way. I still would like to see someone do it successfully and make 20-30 hp, although I don't see that happening.

Small secondary motor to power the electric supercharger.

 

[Skidd]

The only successful electric supercharger

Thomas Knight Turbo Electric Supercharger - Tech Review - Turbo Magazine

 

[krotch]

So it's pretty much exactly what I was saying before. Instead of a capacitor, they just used multiple batteries to power it. Lower power gains with the batteries, but longer running time.

 

[thestory8]

I believe that is the electric supercharger.

AKA a fan

 

[ivonko]

i got one of these for free when i had my honda civic. i put it in for kicks to see what would happen. and i honestly believe i saw a 1-2 hp difference. going DOWN. lol my car had basic bolt on parts on it and after installing the "supercharger" i lost some throttle response and it sounds like a fan going off all the time in your engine compartment. i took it off the next day. its probably somewhere at my parents house to this day.

sum it up electric supercharger= WORTHLESS

 

[RotarFreak]

I've posted these before a few times. These are pictures I took at an auto show a few years ago.
The electric SC on Tiburons produce enough flow to generate around 6 psi. There is a kit name in the picture, so can do your own googling

Price for these sc was around $2,000... not $50 from ebay.



few unrelated pictures since i'm uploading anyway

 

[krotch]

I think they said the Thomas Knight one is around $4k or something. Too lazy to go back through the article.

As for the Tiburon one, probably no different than the Thomas Knight. You'll require more batteries to power the turbine, but the alternator can't charge the battery faster than it gets discharged. So time limited. There's always higher powered alternators, but that'll require more power to run, which will partially negate the effects of the electric supercharger. I think the electric supercharger is a great idea for 0-60 mph times, 1/4 mile runs, and short time attacks.

Edit:

Is that the international car show they have at the Coex Mall? I went to that back in 2010 and found it a huge waste of my money. If it wasn't for the fact that it was at the Coex Mall, it would have been a huge waste of time too.

A friend of mine had one on his Cavalier. Definite power loss. Not only does it lack the pressure to actually provide any benefit, it also restricts the air flow when the engine starts breathing heavy.
He also tried an electric leaf blower; same results, goofier looking installation.
