Not sure what I am talking about? check out this link http://www.electricsupercharger.com/

I have done a little web-research and found about 70% of people think they are worthless and 30% think they are ok. I though I would see if anyone in the caddy arena have tried them or want to throw in there two cents.

I have no experience with this product, BUT it seems to me if it did work so well, you would see them on more cars. Not to say that rare things aren't as good as common things, but in this instance, I think my logic is sound. My advice to you (if you really want to upgrade performance) is take that $300 and upgrade (widen) the exhaust and get a K&N... that is if you haven't already. Why is it only sold on the net? If this item is as effective as they claim, wouldn't they have a contract with at least 1 speed shop? Take a look at the guarantee. You have to take the car to a dyno (if you know where to find one), send them the slips and the unit back (now you have paid to ship this turd twice). They'll reimburse you half up to $50 for the dyno time, so you're still out half your money from that. If the STS is one of those "rare cars" that this product doesn't work on, you will have paid $50 to find out, not to mention the time and inconvenience.

Good point(s). Which exhaust do you reccomend. I have a welder, pipe bender for up to 2 1/4 inch and could probably get a pipe expander for pretty cheap, so I can fabricate most things. However a bolt on exhaust is still ok with me. My biggest concern is noise. I want preformance but I want Quiet too. The Caddy is my power touring car. My first(and still in the stable) car is a 1975 camaro 4 spd with dual exhaust that dumps out under the car. This is what I used for all my first road trips so now I want my ride to be smooth and quiet---yet very quick.

O yeah it is easy to find the KandN filter for my car 96 STS? Or are there several options with varyign degrees of preformance?

I don't have time for a long response, but I have experience with these. Mediocre results, but there may be potential. I'll write more this evening.

the guarentee only claims 4-6% increase....something you can easily get with a k&n filter. This thing is a crock.......its a filter that lets more air in big whoop buy from someone you can trust.

I got the same car as you. Here's what I did: removed the cat, changed the Y to 2.5 inches all the way around, and changed the muffs to dynomax super turbos. I felt a noticable change of power, but it is also markedly louder. Kind of like a trans am. Pretty quiet at idle, but roars in acceleration. You still have to turn the radio up a little louder. Probably not what you want. Someone else here has to have other muffs on. I heard borlas and bassanis sound good? As for the filters, everything I have heard says stick with the stock airbox. K&N says they don't make a filter for the 96-97 seville, but just use the one for 93-95. It fits like a just slightly oversized glove :D. I've also heard good things about removing the honeycomb filter from the MAF. I did it on my car the same time I changed the filter, so I don't rightly know what power came from where, but that honeycomb sure looks like an aweful waste of space for what it's supposed to do. But who am I to 2nd guess GM :rolleyes:

Cool, so three questions,
1. Do you now have true dual exhaust now?
2. So are you are you or are you not reccomending a K&N filter change?
3. Where it this honeycomb filter? Dose MAF stand for MassAirFlowsensor?(sorry I am kinda new to hot rodding fuel injected cars)

1. I wish I had true duals. Mine is just dual from the Y back (which is stock), I just have an extra half inch on each side leading to the muffs.
2. I swear by K&N. I wouldn't use anything else. Every mechanic friend I have tells me they are the best.
3. Correct, Mass Airflow Sensor. There is tube that leads from the airbox to the MAF. Remove end that connects to the MAF and you will notice a white honeycomb looking filter in the MAF. This filter is plastic and comes out easily with a little prodding, BUT I would remove the MAF from the intake before you take it out. Reason being that if you accidentally push filter fragments into the intake, you're probably gonna have very expensive problems. Just take off the MAF remove the secondary (honeycomb) filter, wipe the MAF out real good and re-attach. Good luck.

Oh yeah, and welcome to the wonderful world of modding cadillacs! It ain't easy, but it's very rewarding. :welcome:

Ok, I will give that(plastic filter removal) a try and put a K&N on order soon as I have some extra cash.

Ok I like the remove the cat idea :D. I could make a test pipe pretty easily. Dose the computer have a preoblem with the cat being on a vacation? There are 02 sensors right before and behind the CAT.

Looks like you can make one hell of a leafblower, I wonder if I can use a rechargable battery? Just kidding

Hey all... Sorry I took so long to reply. Here's the info I have: For a while I was intrigued by the idea of electric supercharging. I believe it has the potential to offer boost on demand without the complexity or parasitic loss of a real supercharger or even a turbo. When I discovered these things I thought I'd give it a shot. I ordered the "super" version with the dual inline blowers. I'll start out by saying these are NOT the things you see on ebay going for 50 dollars. (if you haven't seen those, just go to ebay and search for electric supercharger). Those things are basically just bilge blowers for ventilating the bilge of a boat. They are incable of generating any usable boost. The E-ram blowers are MUCH more powerful. It's actually an impressive motor they have in there. If you hold it in your hand and turn it on it'll really pull your hand around a little. The volume and pressure really seems like it might be meangful. I honestly believe that if you put one of these things on your car, properly, under the right circumstances, you might experience measurable gains in power. Nothing like a real supercharger, but 5-10 percent. No K&N will give you that. So I think they have potential.

Here's where my story changes direction: First off, the quality was not nearly what I was led to believe. At the time I bought it, the ads showed a quality axial compressor in an aluminum housing. I ordered the dual inline system which was supposed to come with two of these, with rubber hose in between them and another rubber hose on each end. When it arrived I found two cheap plastic axial compressors in cheap plastic housings. One of the rubber tubes was missing altogether. I found that the housings were so flexible that when you tried to secure a tube to them using a hose-clamp, the housing distorted to the point where it made contact with the blades of the compressor. Cheap Cheap Cheap!!! On top of that the wiring looked like something that could have been thrown together in 3 minutes with parts from radio shack. The icing on the cake was the second motor. One motor worked fine (and it is based on this that I gave my above impressions of it's power). But the second one....was burnt out when I recieved it. It never once spun in my possession. I contacted the company repeatedly about this and NEVER got a response from them. All things considered I think they have a nice idea, and the potential to make some power in the right hands, but the product is critically flawed due to cheap components, poor assembly and horrible customer support. If anyone wants to try making their own electric supercharger, I don't want this post to discourage them. I really think it might work. But that company seems to be more interested in making some money than in helping people make power.

i know someone who tried to make one out of an electric toro leaf blower. he used a power convertert to make the 12V DC 120V AC and it ran fine.. except he didn't plan a way to turn it off at idle and it burned out a $400 power inverter, and alternator, and a batterey.... oops. but it wad a bad idea fromt he start cus the CFM on the leaf blower wasnt enough to handle a 4.6 SOHC Ford motor at WOT.

i think this electric supercharger is the same bad idea to catch people who dont know any better.

there is no such thing as a cheap replacement for the real thing... if there was a good cheap replacement, dont you think more people would use them?

Just curious of a couple things. Did you try this on your 02 Deville? Did you hook up the throttle position sensor as the trigger for turning on the blower or did you have a switch and just turn it on and off your self? Was it easy to fit in your engine compartment, were you using a K&N or the stock air filter? Also do you think the computer can compensate quick enough to change the air/fuel to make a real difference with the product, or dose the car just have more power due to the denser air?

No, I did it on a 94 intrepid. I had it hooked up with the throttle position switch, but after a while I just set it up so I could press the button manually. I think the computer should have been able to adjust fast enough. That car uses a speed density system, so it measures the air based on absolute pressure in the manifold. The sensor goes up to one atmosphere and it was running well below one atmosphere at full throttle due to the intake restrictions. It should have been able to sense the increase quite clearly and would react immediately. As for actual performance on the car, I didn't see much worth noting. As I said before, one of the motors was burnt out and the plastic housing and compressor really inhibited the performance. But I still think it could be made to work.

As for the "if it's so good why doesn't everyone do it" logic... Well turbos are good but very few people have them. Electronic fuel injection is good but it took decades for that to catch on after it was developed. There are lots of good things that people fail to use. Just because it's not in use doesn't mean that it doesn't hold potential. If we all thought that, we'd still be walking everywhere.

It is to control the air turbulance going across the MAF sensor and down
into the engine. I recommend you don't mess with it.

go to www.cargodzcc.com (http://www.cargodzcc.com) then to the shop section. you will find the e-turbo info there. theres a link for it. you will find these to beimpresive for an e-charger.

ScottThe honeycomb is to straighten out the air path over the maf and to maintain consistency of flow at rpms.
I would think that the electric supercharger idea would not have been very successful at least in the past because the motor to drive the charger would need to be powerful and compact (maybe a flat pack motor?) wich even if it could have been made before recent advances would be expensive. That pre- supposes it's possible even now.
That's not an expert opinion on my part, just an opinion!
