I am seriously considering purchasing an Electric Supercharger. Is it worth it?

[itsbudda]

I'm not here to start trouble or anything, but I really want to know. Has anyone actually tried the Electric supercharger, and if so, Is it worth the $99? I'm actually considering purchasing one and would like your input. If the supercharger doesn't work, it looks to be a better intake either way than stock.

please dont.

[itsbudda]

Any particular reason? It seems like something worth trying, but maybe the battery weight would neutralize any power gains.

[moparfwdsleeper]

Spend the $100 on something that is a power adder ESs are just a waste of install time and cash.

[itsbudda]

alright. To heck with this idea. It sounds like they're crap. Some guy with a Maxima blew the engine with one. They sound dangerous.

[Ondonti]

Probably blew the engine because it broke and sent parts into the engine while it was busy restricting air into the intake manifold. The restriction removed itself but it hurt the motor

I have never seen and true results anywhere from what they claim.

Anyways it is just trying to add cfm and with not way to restrict backpressure back thru the fan assembly it is not doing anything. Only true way to add cfm and power is with a turbo or supercharger since the levels are high enough and design of the system provides positive pressure to the motor.

$100 could get many a decent upgrade to help boost power.

Who would want to drive a Maxima now a days anyways?

[itsbudda]

But that's what everyone's telling me. I just mostly wanted to know why it doesn't work. Thanks. I'll put my $100 to better use. And the E-ram claims to make 1 psi. $300 for 1psi? you could buy a whole car with a turbo for that if you wanna do some work. Another one says it makes about 8 psi at launch, but it goes down to like, 3 or so while accelerating. They're crap.

nobody.

For an electric turbocharger to work it would have to use motors that are the size of starters and turn faster (or are geared up)!

Here is an article that does the research:

I got a question about these things. now... forgive me if this sounds silly, but for the most part, these things are just giant souped up fans. la de dah. they suck a buttload of juice to BLOW AIR AT YOUR INTAKE. hell. if I didn't care about the weight problems, I could duct me an old squirrel cage fan into my engine, and run it off a power inverter. hmmm.... y'know theres a lotta room under the hood of this old truck I got...
Now if you really want power for cheap, you gotta go for the weird and wacky. Some buddies of mine started up Stupid Fast Inc., where we believe that just because you spent more money on food and beer last week than you did when you bought your car, doesn't mean that you can't turn in acceptable quarter mile times. We call the following the LHIS (Liquid Hate Injection System).
1. Get an old washer fluid tank & pump. Caravans work good cause a lot of them have low fluid sensors. Also get some small hose and the washer fluid nozzle off an old chevy truck. They're just a bit of metal tube with the end crimped.
2. Rig the chevy washer nozzle (injector) into your intake somewhere pointing at the throttle plate. Don't let it get near rubber though, Liquid Hate hates everything and will eat your hoses. (out of sheer spite)
3. Acquire some Liquid Hate. I suggest at least 10% nitromethane or you're just burning alcohol like a pussy. If the engine is good and hot before you do this, the fuel will all evaporate before it gets into the cylinders.

Before anybody laughs too hard, we did something similar to this with an old uhaul truck named The Beast about 6 or 7 months ago when the boss wasn't around. The tire marks are still there. It also works great in gas powered lawnmowers if the grass is too tall.

If you think about how they work and the source of the energy used to power them, the answer is self-explanatory.

A supercharger is powered directly by mechanical rotational of the crankshaft, which saps some power (about 30hp for every 100hp created through boost) due to parasitic losses (more load on the crank shaft, belt losses, bearing losses and gear losses through the blower drive.

And electric supercharger is going to have all of those losses PLUS the losses associated from the conversion of mechanical rotational energy (the crank) to electrical energy (the alternator) and then back to mechanical rotational energy (the compressor wheel). The electricity is not free, it comes from further loading of the alternator or battery.

One might be able to get a quick burst of boost from pulling on the battery, but there is no way in hell you could pull enough to support a decent amount of boost. To put in 30hp worth of compressor power (typical for the boost needed for a 100hp gain in the engine), the electric motor would draw 22.37kW. At 12volts, that’s like 1,860amps!

if you want an idea of something with a strong enough fan to increase horsepower, watch the Youtubes with the kids with the gas leaf blower hooked to the s10 and the civic, that produced enough forced air to produce i think it was 15 eextra hp

[itsbudda]

Thats one of the best ideas i've ever heard. I heard it knocked a second off of some dude's 1/4 time.

[t3rse]

15 hp knocks off a second??

[big_P]

yes, not even in a Civic.
