Has anyone checked this site oout or even tried it? Click on the video demonstration. Looks neat, little pricy.....what do you guys think?

 

[Sir Nuke]

we have run this one through the ringer here before...this thing is total BS.

 

[big_ben]

It's a piece of crap. I'm not saying it's not a good idea though. With the right R&D and the right engineers behind it, it could be made to work great. But not these garage mechanic rednecks.

LOL!

You know, I was thinking today...they have turbos that run off exhaust, superchargers that run off a pulley. Why not a magnetic type supercharger. Like power from the engine could run a series of powerful magnets that in turn spin a shaft that powers a turbine in a compressor (or a supercharger type mechanism) I'm sure there's ups and downs to this...but has anyone heard of it being done before? If so, please post a link or something.

Can you imagine how fast the turbine would be spinning if this was done right?

Sounds like a good idea keepOne, but in reality what you describe is a very basic elecric motor and i think to get it to work right you would have to go maybe 1/8 - 1/4HP which will spin around 3600rpms or higher. Practically its not such a great application, for the elec. motor at least. The high heat of the engine bay and the vibration of just driving would kill it. Most motors that spin up 3600 are known as two pole motors because of the design of the windings and can take very little to no vibration. I've got a prime example of this in the shop right now, one of the end-bells was cocked almost .005 of an inch and fried the bearings and tore the bearing bore up. If you could make it work in the enviroment I'd say go for it, but I think it'd be extremely difficult if not impossible to get one reliable. BTW if you want some info on electric motors check my company's site out www.emc-co.com and check out some of the links there, it's some good info to get you started.

I posted a link to an ebay listing about 2 weeks ago that had a centrifugal supercharger with a motor mounted to the back of it instead of a pulley. They claimed it got up to 4psi. If that's true it wasn't a bad deal. It was going for only $400. At that psi, there is no need for a intercooler or even piping. You could hook it up directly to your intake tube. It is an easy and cheap way to gain about 40hp. Cheaper and safer than nitrous. But this was the best idea I had seen in this area. In order to get any boost you need to get a motor that will turn at least 60,000 to 90,000 rpm. Most turbos spin at over 100,000rpm. You would also have to get a huge alternator. But if you had an FS-ZE motor,...ahem...linuxracer,.....this low boost setup would be perfect for you. There would be no restriction on the exhaust, you could turn on the boost when you wanted from the cabin, and still get the same gas mileage when you didn't want any boost.

I would like havin a real supercharger. That electric one, however isn't really anything other than a waste of money and time.

 

[Kooldino]

Actually, I believe it.
"5 to 15 more horsepower" is what it guarantees. FIVE TO FIFTEEN. That's not a lot guys...it's not like they are claiming a 30HP gain here. The replacement of your stock intake with this and the cone filter ALONE should get you at least 3HP...and 1psi of "boost" could add another 3. So that's 6HP for YOU.

Out of curiosity, how fast does a real supercharger spin if it is hooked up to the crank? I would think it can't spin faster than the engine, but I know nothing about superchargers. Can somebody confirm this or fill me in?

I don't raelly know, but I do know that it spins much faster than the engine. It all depends on what size pulley you have on the bottom end.(on the crank) If you have a 6" radius pulley at the bottom and a 1" radius pulley on the supercharger, just multiply your RPM by 6. So at 7000rpm you have 42,000rpm in the supercharger. It isn't as high rpm as a turbo but the centrifugal supercharger has different blades than a turbo. They push more air but require more torque.

Alright maybe it isn't such a great idea...but hey...you never know what'll happen in the future.

Duh, that makes sense. I can't believe I couldn't think of that myself. Big pully "chained" onto a small pulley rotates much faster.. Duh
