Exclamation Adding an electric supercharger to a 2000 XK8 convertible - good idea?

http://www.superchargerswarehouse.co...Superchargers/

Seems like a fun mod, any idea what to expect from it? I.e. how many - if any - hp?

seems like so many other gimmicks I've seen for "fuel saving, performance enhancing". I would have my reservations....but if you DO give it a spin....post your findings...

There are so many reasons why this can't live up to it's claims. Send me the $199 instead. I promise to only spend it on something that will actually benefit a Jag.

if this really worked every car manufacturer would use it, all it is a little $5 electric fan that you would find inside of a computer. This might be able to produce .005 psi of boost, or something useless like that. This might gain you 1 or two horsepower, but certainly not 80, 80 horsepower is like the difference between the older XJ and XJR, and they got that 80 horsepower increase with the use of an actual positive displacement roots-type supercharger, that runs at 12 psi (maybe 11.5, something close to that) of boost. This is just a gimmick.

The Eaton M112 uses about 60HP to make 10 to 12 psi boost.

An electric motor moving that much air would need to draw an amazing amount of current.

Looked at the photos of said "supercharger" and it almost looks like the fan blades were cut with tin snips. The text says a 3 psi boost. Now, I admit I'm not all that familiar with superchargers, but I'm pretty sure this wouldn't create an extra 80 horse power. It also does not include that pretty chrome pipe. Of course, I've been wrong before, but, until someone proves otherwise, think I'll just stick with my xkr.

What ever tiny amount of horsepower it helped create would be consumed at a rate greater than 100% by having to drive the alternator to produce the electricity to run the electric fan motor. Very inefficient at best and bad science and myth at worst. Save your money.

Thanks, looked to good to be true, and you also have to manually activate it

Any cheap XK8 mods that are actually worthwhile though? Either improving fuel economy and/or performance?

hi fellas,
i fitted this to my XJ8:
http://i1106.photobucket.com/albums/...dja/turbo1.jpg

i can categorically state: a very noticable improvement. i didnt drive a lot of miles as the car was not primary transport but the acceleration was noticably faster and of course the sound? well, as i had a straight through stainless steel sports exhaust fitted from the cats back, i am sure you can imagine!
as far as i am concerned, i think its a great idea, easy to install and if anything can help with the fight against rising fuel costs - why not?
good luck and happy driving.......
dom.

THese are all crap - you can't beat the laws of physics.

Many horsepower are required to move enough air under pressure (this is what boost is) into the cylinders, this would require an electric motor about the size of a Prius's and more current than your battery and alternator combined could provide.

These things are simply marine blower fans being sold as 'turbos' - fans can NOT move air and pressurize it at the same time... there's a sucker born every minute, and anyone who feels an improvement is likely to feel the same after washing the car or changing oil, aka 'Clean Car Syndrome'.

Best power gainer for natural aspirated cars would probably be these boostbars, man just think about it, 1 solid boostbar per bank at 14.5 psi!

Avos i really like the brass ***** and the cross drilled brake hoses on the site. Maybe i should order 2 bars for the nissan and my boost will be up to 2.5 bar, ill be able to smoke a viper....er smoke something

These guys have some great genuine products, really well thought through. Once you understand the true magnitude of the specifics, you can understand why the established automotive industry is trying their best to ignore their existence. I am actually thinking of testing their improved Kuneutson valve, and the oil bypass kit sounds very temping aswell, don't know what to chose first

Do they have any left handed exhaust shifters? Ive only been able to find right handed ones
and i ordered some of their synthetic blinker fluid, that should stop the corrosion i have issues with..
and on that 3 psi electric blower, thats is probobly a dead head pressure, it needs to move more air than the engine can injest at any given time. guys, boost is created when there is an obstruction to flow in a roots application. take a 12 psi BLOWER SETUP off the engine and drive it to twice the rpm and without anything to impede the air flow no boost is created. lots of air flow which is what a roots blower does. it just forces more air into a engine than it can injest. only the twin screw design actually compresses air inside the blower case.

Lmao, don't start the Dino vs Synth here, but their claim sound to good so must be true. How they have been able to even increase the the dot specs tenfold, yet remain fully non-legal dot is admirable. Just saw it sold out (no wonder), can you share some left side fluid?

Bwahahaha!!!! :rofl: I really like kalecoauto.com's radiator insulator! Just think of the gas I'll save by preventing all of that heat energy from escaping!

It's a parody site. And a damn good one! The cross-drilled brake lines had me rolling!

LMAO!!! Check out their all wheel drive kit! http://kalecoauto.com/index.php?main...srp5glbmvi1u70

That website was a great find, avos. I spent 5 minutes looking at the boost bar trying to figure out how it worked! LOL
