Electric Supercharger!! Good or Bad?

MatyBMW · 03-25-2002, 10:08 PM

Has anyone actually TRIED the electric supercharger.

They claim a money back GAURENTEE for 4-15hp.

www.electricsupercharger.com

Its a fan that is mounted inside a hose that is fitted after your mass air flow sensor but before your K&N.

I hope somebody has some comments on this thing because I am definetly considering it.

that sounds like bullshit to my dude!
for one, the fan motor will get hot after while and increase hot air into the intake (

)
yer engine doesn't need that xtra air to lean out the mixture

and theres probably more stuff but I can't think of it right now,
so my point--

BUt my point is..

I'm sure they've taken the heat situation into consideration and they have probably done something about that. An engineer isn't going to put out a product like this without putting everything into perspective.

And how does a supercharger work? It runs off your timing belt so the fan spins in proportion to the motor. This works the same way, it has a wiring harness that allows it to spool up in sync with the motor. It runs at 1 PSI which should theoretically give you around 9hp, depending.

I also believe that it will work better with a performance chip. It will make a much better air/fuel mixture and add to the performance.

I think it sounds good until someone can prove other wise.

Thanks for the comments.

Yeah, but I bet there's more marketing than engineering involved here. U'd figure if it worked really well lots of more people would be using it. Superchargers have to be precisely tuned, I doubt this works.

i wouldnt do it if i were you, sounds like a farce,,,, but on the other hand maybe you should get it,, and give us updates on how its working for ya,,,

In theroy it may do a little bit, but isn't it like 200-300 bucks?
screw that

Joel_BMWracer · 03-28-2002, 04:34 PM

In theory it should work. Just like RAM air induction. But I'm not sure if it is worth the money. I have also seen them for V8's but they are from B&M and large companies that are known for quality.
These are some things you need to look at before spending the money. I am also looking at this type of upgrade :-)

Please let us know if you do get it.

Thanks,
Joel

Have you looked into this product any further? Sound really cool to me. Let me know, Im interested In the consept.

jacob.325is · 04-02-2002, 01:52 PM

Ohhh my, someone put one of those on their M3!

MY opinion, a huge waste of money.

theblue · 04-02-2002, 02:21 PM

it's a known scam... avoid it

Carlo · 04-04-2002, 12:15 PM

If you can double the amount of air you engine will intake (Increaseing your Volumetric efficiency), In therory you will double it's output power. So weather it be 10 psi, or the 1psi they claim, it should prouduce HP, wright? The only thing that puzzels me is how does it not create a restriction in the intake when its off or not a W.O.T.

Did you know Gas engines are only 10% efficient
and Diesel 15% the other 90-85% is lost through friction heat and other production imperfections...huh

theblue · 04-04-2002, 01:05 PM

ok, I'll give you credit that I'm jumping to conclusions a little. Do a search, its interesting that there are several places selling this type of product and I can't find one person outside of their websites that can show any gains at all, nobody has any dyno charts showing gains so I really don't think it will help.
I can't help but be sceptial when I've never heard of any cars that are modded and fast using this.

One of the issues with this electric superchargers is that they draw A LOT OF CURRENT. This puts stress on the alternator robbing you of the power that the "supercharger" makes. So the gains at 1PSI would be VERY marginal, and if you add OBD-II adaptation on top of that, you mostly like won't even see any gains at all. So for $300US or whatever it's totally useless.

This is a very good point!!!

Lonely TI makes a good point.

I personally know someone with a '97 M3 that has an electric supercharger installed. It does work and you can definately feel the difference. The unit spins up to 30,000rpm and does draw quite a bit of amperage from the alternator. It comes with a ON/OFF switch so you don't always have to run it. It produces 1 psi of boost (good for about 10 to 14hp) but robs the motor of a free flowing intake when it's switched off. You can hear it.... sounds pretty cool. This person I know doesn't live in Canada, so don't ask me anything else about it... this is all I know. I guess it all comes down to cost of the unit. Any way you look at it, 1-psi is 1-psi of boost.
