Been following the forums for along time but never posted. Very helpful website. I have a 96 (SC), and getting ready to spend money that I DO NOT have on it. First off, thanks guys for answering alot of questions for me(Recently how to turn the stinking calipers with channel-locks, because I bent 2 c-clamps!!), but here is something I found. [u]www.electricsupercharger.com , this is not the junk ones, this is patented. Was wondering if you guys think this would work???Expensive mod, but I do enjoy the look on a guys face when my "Grandma-like Buick" smokes his little souped-up foriegn job!!!!Let me know about the electric SC and if it would give us a little more UUMMPP!
Thanks guys, and again thanks for all the help!

just a quick question , you said up above that ur car was SC. so yuo already have a supercharger. i dont really want to sound like a smart ass but why would you spend 200 bucks on a vacuum engine for that price you could just get a smaller pulley and a FWI. and you would make way more power then a electric supercharger.

i hope this will help you out with ur power "surge", if you do them too you should really open up the exhaust too. IMO dont waste your money on that electric supercharger. thats just worthless crap.yes that is my opinion but i also know that a pulley intake and a tweaked exhaust will make way more power then some vacuum motor

good luck to you and welcome aboard this is a great fourm and a great place with great people that will try to help you out any way they can

it wouldnt help you TOOO much............. it might even restrict how much air you are pulling in (FROM THE SUPERCHARGER ALREADY ON THERE)............ IN fact DONT DO IT......... there is a much cheaper option to getting more power for less money.............. get a MPS 3.6 inch pulley and a FWI for UNDER 150$ you will be very satisfied.

Bad!

Corey and Travis are absolutely correct. This item is not for you. Here's why...

Your engine comes with the M90 supercharger already under the hood. From the factory, your M90 pushes about 6-8 lb of boost into the engine. The electric supercharger you found only makes 1 lb of boost. So, if you install one of these, at best you're getting 7-9 lb of boost PLUS a significant drain to your electrical system. At worst, this electric blower could (probably will) restrict the flow of air to your engine, so you could end up with even less boost than you started with.

Not to say electric superchargers don't work. On a naturally aspirated engine, particularly one with a restrictive intake, this unit would make a little bit of extra power in the same way a cold air intake system does, by providing more air to the engine. But with engines already using forced induction, adding a unit like this just isn't needed. The medium-sized M90 supercharger is so much more powerful than even the largest electric blower. To put into perspective, the M90 requires up to 50 hp just to operate at max levels. This is more than 3 times the hp increase the electric supercharger claims to create. Sounds backward until you consider the gains of the M90 are more than enough to offset the power required to drive it. If you were to remove your M90 blower from your engine right now, you'd likely lose close to 70 hp!

I thought the N/A cars made 220 hp?

If so, and the electric blower made only 10 hp (I've got no idea how much it would make), in terms of hp it would be very close to a M90.

Torque might be another story entirely.

I think this could be a great idea, if not with the current units. There are electric motors stronger than 50 hp, and the torque is phenomenol. You could be making 10 lbs of boost (or more) at 1 rpm. You could tune the daylights out of your boost, without swapping a pulley.

The question is, what would you need in terms of batteries and capacitors to run it? It doesn't really have to run for long. In normal use, less than 10 seconds at a time. 16 seconds max for the quarter mile.

The Series II N/A engine made 205 hp, and the Series III N/A used in the Lacrosse only specs 200 hp, even though both engines are basically identical.

But the N/A 3800 uses 9.4:1 cylinder compression to make its 200 hp, whereas the S/C version uses only 8.5:1 compression. It needs boost to make up for the lower ratio. Without the blower, it would make quite a bit less, maybe closer to 170 hp, imo.

The N/A 3800s are already torquey engines down low. Adding boost to the intake would only help, regardless of an electric or belt-driven blower. I agree an electric blower could be a great idea, but the price and power consumption of such a unit is concerning. Even more crucial would be overcoming the thermal problem of the blower being superheated by the compressed air being pushed through, combined with the heat of the electric motor coils. Sounds hot, hot, hot to me! Lots of R&D needs to be done on such an idea before it can reliably work. The electric units out now could not even come close to standing up to such intense heat, imo.

Ah, I forgot that they dropped the compression ratio on the SC motors.

I agree it would take research to develop a truly good electric SC. By the time it's all said and done, I'm sure it's much better to put the electric motor between the engine and the transmission and have it apply power directly into the drivetrain.

Probably right. Even if I do gain a little HP, it would be moot due to the restriction of when Im not WOT. Thanks guys.

BUT..........

I have always wondered what this would do to a naturally aspirated car?........ i wish i had a dyno

It wouldn't do anything. A little electric motor spinning a little fan that's sucking air through a huge cone filter wouldn't make any significant boost.

RICE-O-RAMA

I agree with IBX1. Seams like a waste of money like the "Tornado".

I would image it would restrict the performance on a SC Riv. If it pushes 1-2psi, I would assume any more airflow would hit the vanes of the electric SC turbine/fan like a wall. If your stock M90 produces 6-7psi the bottleneck would limit your M90 to the best performance of the electric SC at 1-2psi. Does this sound correct?

If anything the vacuum from the S/C would supercharge the electric fan thingy.

Agreed. It would and by doing so, the M90 would lose effeciency. Not only would it provide boost to the engine but it would have to use some of that boost to produce vacuum to get over the defiency of the electric SC.

I'm thinking of designing something useless so I can make some money too! My design of muffler bearings was already taken tho... (props to TType_Riviera) Maybe some square wheel bearings for more surface area for the grease to stick to!

So in essence it's like putting a block of foam in your intake, it just makes the S/C work harder, the engine work harder, using more gas and producing less power. If you have a n/a engine, it's an okay deal but it's very expensive. You'd be better off putting a turbo or something on. If I had an old Saturn or something I wouldn't rice it out with this, but I'd rather turbo it.

If you're already boosted or blown, forget about it.
