We had an event on at the club last night, and as i approached the club there was a nice black Lexus IS200 Sport (Y reg). It had Lazerlight International stickers up the side so i knew it belonged to the company doing the event. Anyhow it was supercharged, and the chap reackons it was done by Lexus, apparently 1 of 6 in the country.
I think he mentioned it had been chipped etc too, not sure in the truth of any of this.
Full Version: Supercharged By Lexus?
Lexus GB do not officially sell the supercharger kit - in mainland europe you can walk into any toyota/lexus dealer and say " i want a supercharger" and they will be happy to oblidge. So If he is saying he officially ordered it and it was officially fitted by a Uk dealer - then i would be VERY sceptical - ( lying) but you never know ............................. 
Sorry about the double posting, it chucked up an error so i tried again.
other than tony getting his fitted at TTE, my car is the only UK car to have had a supercharger fitted at TTE.
all cars in Germany that wish to have the S/C fitted have to have it done at TTE
THERE WERE 5 CARS SUPERCHARGED BY LEXUS GB
only 2 are still around, these were built at TTE and shipped to the UK in 1998 and stored at Lexus Milton keynes, where they could be tested at the Milbrook proving ground.
none of these cars ever went to private buyers
the 2 that are still in use are at Lexus GB test unit in Redhill, Surrey
the other 3 have all been crashed by eager lexus executives
its not possible that he could have an officially S/C uk spec car, they were never procurred because of Homologation rulings .
Technically, my car was the only official UK car Officially supercharged by TTE.

Lexus were going to release 180 (ish) special edition Is200's but the warranty company would not warrant the engine so the idea was scrapped.

BUT - soon there'll be another ... hey Chris
Can i be 1/2 official ?? Huh Huh, please Mat, can i, can i, please, huh, hu, oh go on

Maybe I'm dizzy or just not thinking or something, but can someone please tell me what it means when the car is supercharged. Does it means that the car is fittet with boost like streetcars? 
similar to turbo mate... but it kicks in at all revs!.. permanent turbo
As turbo usually kicks in at say 4000 revs.

Thks a lot! Makes sense! Should be on all the IS200 as the car doesn't kick before 4000rpm anyway (Which is far to high) . 
actually not like a turbo really.
a supercharger is constant driven from the engine,(unless an electronic or centrifugal clutch is fitted) the compressor(and there are different types)compress's the air and forces it into the engine, compression can be by several means.....rotating lobes, rotating spiral vanes.
so, supercharger, mechanically driven pump basically
a turbo, is driven by exhaust gases leaving the engine, the gas passes through one half of the turbo and turns an impeller, before travelling down the exhaust pipe.........the turning impella is fixed to a shaft which in turn , turns another impeller, which draws air into the turbo unit, and compress's it ...forcing it into the engine

OK - Zee gets to do mechanicals ...
Harty gets the electrics ...
Uh Oh ... Run for your lives .... 999 ... which service ... FIRE ...

you all make me laugh!!!
I personally like the techy bits as its hard to find that sort of info for our motor!
Also, its good to see that we have some very technically competant people here who can help out - top dollar too you!
Anyone have any power/torque curves for the IS200?

Whilst youre in the mood, can you please explain what chipping is and what does it offer in terms of performance on say a standard IS200.

have just uploaded power/torqe curves to the gallery to try and get them to here but i have lost them lol HELP

"Chipping"...? That'll be Lexus' cr@ppy paintwork!
Sorry, couldn't resist that
Ok... the guys will be along in a mo to give a proper reply

still lost the pics 
could be gen thou i know where there r a lot of kits here in uk not sure of price thou? the chip could just be the ecu ext that comes with the kit

Hmm, let's see if i can help out here ....
Engine management computers decide how much fuel to inject into the engine and when to generate the spark to ignite it based on inputs from various sensors. These could be in areas such as exhaust gas, coolant temperature, inlet manifold pressure, turbo boost pressure, engine speed and so the list goes on.
It's like a big 'look up' table. So the ecu might say ...
Exhaust gas reading is 'A', Coolant temperature 'B', Engine running at 'C' rpm.
So according to my look up table i must ....
Open injectors for 'X' milliseconds + generate spark at 'Y' deg before piston reaches top of stroke.
This 'look up' table or 'map' is the heart of 'chipping'. The 'chipper' replaces the standard 'map' with a different one. Standard maps are normally a compromise of performance and economy / emissions. Chipping would generally aim to tilt the balance in favour of performance.
Some maps are on a memory chip and can be replaced with a custom one - hence 'chipping'. If this isn't possible, a supplementary computer (piggyback ecu) is used - such as the 'unichip'. These wrap around the stock ecu and alter it's inputs and outputs as required to achieve the required effect. Taking IS200 as an example, TDI use a unichip to achieve a modest power increase AND reduce fuel consumption ... Blimey
As for supercharger 'chips', the earlier kits contain a small black box. This intercepts the manifold pressure signal before it reaches the ecu which expects to see a vacuum as air is drawn in but would see positive pressure as the supercharger forces air through instead ...
Well wouldn't you be confused if expecting to suck but getting blown instead
Later kits have a larger silver box which does a similar job but provides additional protection from fuel cut off - to protect cat converters from meltdown apparently.
That's my rather simplistic view of things - hope it helps
There are much cleverer people here who can elaborate i'm sure
