On eBay - 911/944/928/Boxster Supercharger - turbo

Hey all,

I found this Supercharger on ebay. Is this for real? will it really work?

Has anyone seen, heard or better yet, used one of these things?

Youll just throw away your $140 for a useless "Leaf Blower"...LOL...There are absolutely no benefits from installing this POS device.

If it sounds to good to be true.....

Appreciate the input. I like the part in the description that states that when you need it you "turn it on." Wouldn't I want it on all the time?

I think it was crazy talk, but I had to ask.

Interesting mix of feedback for this seller.

1. I always find it surprising that people will still buy from sellers with so much bad feedback (this guy's isn't as bad as many power sellers I've seen), but 32 people in the last 12 months did not have a good experience.

2. It seems he sells superchargers for many makes and models and surprisingly some folks felt a power increase. Suspiciously, all the item #s are "private" so perhaps it works for some cars. However, a good number of people left positive feedback before installing, another unexplainable phenomenon.

3. Got a good laugh out of this feedback:

"Pretty good product got more power with it switched off"

LOL!!!
Gota love the feedback
It should work how ever the key will be the blower. It has to spin up fast enough(not normaly a problem) most important have a high enough flow rate. I doubt that one could realy make 2psi of boost.
Just my 2 cents.

Hi,

Sorry, but it's mostly a waste of time. As one mentioned, it is a Leaf Blower.

There are no free lunches where making power is concerned, everything is a trade-off. If it were that easy, the Supercharger and Turbocharger would have been put to death years ago, in favor of an electric induction system.

Turbine (fan) design is a very intricate science. It would be very easy to have this 'Fan' cavitate long before it ever produced any appreciable boost. Also, for it to be effective, it would have to draw so much electrical power that every other system in the car would fail and your alternator would burn up in a block.

Just as an example, take the Supercharged Jaguar XKR. At full boost, it produces a net 390-400HP, but the parasitic draw of Crankshaft power by the Supercharger is 86HP. If you had an electric Fan which was more efficient, even twice as much, it would still need a 43HP motor, can you imagine the power draw of this thing?

I suspect most of the positive feedback was done either prior to installation of the device, or it's just a Placebo Effect, because the Science simply doesn't add up.

Happy Motoring!...JIm'99
