Krisby1 I know mate was just saying it was a supercharger due to the end result i.e the output bhp figure when compared to a supercharged engine making the same output bhp figure. power is power regardless of how an engine is aspirated or how the power is generated so a 211bhp high rever will pull as fast as a 211 naturally aspirated and those two will also pull as fast as Supercharged engine making 211bhp when car weights tyres and gearing ratio are equal between the three..I know how forced inductions work and all they are doing is increasing air occupied in a smaller cubic capacity to match that of a bigger cubic capacity...end result will be the same with all things being equal between the three differently aspirated cars.. so yes a supercharged is not physically bolted to the engines but the power delivery and bhp generated will be equal to a supercharged engine which makes the same power.

so you now know why i have a supercharger without a supercharger right :winky: . all down to the volume i can cram in my bigger bore cylinders..

dont forget its not how power is made thats most important but its the end result(total power) thats most important... dont believe me?? a 2009 AUDI S4 Coupe is a 3 litre Supercharged engine making 330bhp now a 2009 INFINITI G37 Coupe is a 3.7litre naturally aspirated engine making 320 bhp...now where is the INFINITI getting its almost matching AUDI supercharged bhp figure from?? its from its bigger cc, cylinder bore size, cams, valves and compression ratio which are all working together to make Supercharged bhp figure. these two cars lined up side by side will peform similar on the road. there are two options to make the same kilowat of power have a bigger cc which sucks in huge amount of volume air and then compress it higher or have a smaller cc which will initially force the same volume of air as the bigger cc into the cylinder using the supercharger and then compress it higher... both cars are now generating roughly the same kilowatts of power at the crank.. the most important factor here is VOLUME i.e. amout of air in the cylinders and nothing else.

Krisby1 no need to apologies mate …!! matt I have a supercharger and no its not bolted to the side of my engine so don’t start moving your head from side to side looking for it when I pop my bonnet open because you wont find it…it hides in my engine block and they a big cylinders which can suck in 499.5 cubic centimetre of air which totals 2997cc when multiplied by 6 and each of my pistons can compress that air into a very small cylinder space at a high pressure of 10.5 :1 compression add fuel and a spark to it and just over 211 bhp is generated with 290NM of torque on tap. That is my supercharger made from a bigger sucking air pump (CC) and not from a bolt on. Oh and I also have ACIS to speed this process up when I hit 4300rpm… why is my bigger sucking cylinder all of a sudden a supercharger?? Because its sucking in as much air and compressing in as much air very hard to match that of any other Supercharged engine out there generating just over 211bhp.

I do agree its all about the petrol usage when its run on boost most of the time but driven normally i doubt it will consume more than any other 3.0 litre engine out there! nice cars tho shame emission laws are now fazing out these legendary machines from Japan. as you said IS300 gives you the comfort and Go for less than a price of a new ford KA :D

I think that would be money well spent lexus loon :D .. IS200 is good for what is it performance and handling wise dont forget it doesnt rev past 6500rpm so more power cannot be extracted from it. if you notice, any 2 litre petrol non aided engine making more than 155bhp needs to rev past 6500rpm to make more power so IS200 is good for what it has at its disposal. for more power and drivability(torque) IS300 answers your prayers...or if you want something which domestic and Supercar drivers fear on the road just get this.. http://www.autotrade...s/200?logcode=p This car and the Nissan skyline GTR are the only two cars which makes Porsche, BMW M3/M5 and and Audi RS drivers give right of way on the motorway without you having to ask for it (i.e.without you flashing your headlights or driving close to thier rear bumper) :winky:

Lexus autobox just doesnt break like that. box might show signs of shifting problems and if ignored by the owner it then gives up...since the car was bought only today i would have it towed back to who ever sold it to you and get your money back or if you want to keep it, might be worth taking it to an auto box specialist for dignosis it might be something small like drain and refill box oil or big bills..

I couldnt explain it myself when i experienced it in my Cougar and in my case it was normal Shell unleaed i used not V power 99RON during that time i was driving 'normal' i.e without putting my foot down unnecesarily or braking hard...I must admint i havent managed to replicate it again either it might be the fuel was really fresh at the fuel court when we filled up or there is a way of driving i.e the right speed, the right throttle pedal angle etc which causes this to happen!! but it sounds like one could extract excees fuel(mpg) from the same litres of fuel but dont know how it came about!!

Let me guess Chris!! Are you using Shell or any form of Top Tier fuel in your IS?? Although I haven’t experienced this spooky behaviour in my IS yet I did experience it in my previous Ford Cougar V6 when I filled up with Shell normal unleaded and the Cougar does have OBC fuel readout so filled up with if I remember £30 quids worth which normally sits at half tank on the fuel gauge when fuel is filled from close to E. after filling I switched to fuel readout on my screen and it showed 120miles. That is 120 miles left before another fill up is needed. drove daily to and from work and on the the third day I noticed although my computer fuel readout was counting down, the fuel gauge was moving but not a lot. I thought this cant be right but I ignored it. so come Friday my fuel readout showed 40 miles left to refill but my gauge had only moved a gauge was still getting baffled by this.. Finished work got in my car turned on my ignition to start and noticed my computer fuel readout has increased from 33miles when I got to work that Friday to 75miles . Was so surprised by this I thought someone or maybe my guardian Angel must have filled in petrol into my car. Normally I tend to fill up on Saturdays for the coming week but the fuel lasted me till Monday which means I got more miles from the same litres of fuel. This has happened twice the second allowed me to drive 15 miles when the fuel read out was showing 32miles after my 15 mile drive it had only gone down to 30miles but this was during heavy snow last year so was only limited to like 20mph maybe it was the weather or the fuel .. but havent experieced it in my IS tho :(

your IS will have tha mean look when approaching from a rear view mirror :winky: some sport yellow fogs will fit in nicely to make it look even meaner

I think its to do with the cars chasis and drive train. Lexus made it so good it made people think its a slow performer compared similar 2 litre 4 and 6 cylinder cars out there. but on the road i doubt a 2.0 litre Accord, Alpha 156, or BMW 320i will perform any better than the IS200 as on paper they all have roughly the same bhp figure and thier power to weight figures are similar so difference will be thier gearing. Others were also expecting a bit too much from the IS200 but they keep forgetting its not a 2.0 Civic Type R. A 2.0litre Toyota Altezza RS200 is a Civic Type R performance.

http://www.vredestein.co.uk/car-tyres/summer/ultrac-vorti/info/ I think its Italian like Pirelli's... as you can see there are lots of posts on here about different tyres to go for based on individual preference or brand loyalty but dont forget we all drive differently and prefer differnet levels of comfort in our cars. some wont mind how noisy or harsh a tire is to the car so long as it handles and grips like glue whilst others prefer more quieter ride and wont care about if it can stick doing 60mph round a bend without loosing grip or how fast it can stop from 100mph to 0 in heavy pooring rain.. if I were in your shoes I would either go with what Lexus fitted your car with from factory as there was a reason why that brand of tyre was used or go for ones you prefer and can afford from the bunch. dont forget there is nothing like the perfect tyre brand as they all differ in the way they grip, acceleration, cornering, noise level, wet handling etc is delivered to the car so .e.g. Continetals might suite Mercedes cars but stick the same on a Subaru Impreza and it will be a different story same as how say Yokohamas will suite the Subaru but Audi A4 wont like it.. tyre choice depends on how a car is setup aswell. Good luck .

I pesonally havent used it so will be more of 'suck and see' if it does what it says on the tin.. I think the main advatage of the valve is to improve trottle response and make acceleration more urgent and smooth as stated on thier website..Lexus IS uses electronic trottle control systems i.e based on how hard/soft one accelerates instant signals are sent to the ECU which then works out what the driver intends to do so this technology is already there in your car. http://www.lexus.com.bh/technology_explorer/electronic_throttle_control.asp?model=All They also mentined the valve helps cause turbulence in the inlet manifold to help fluctuations in operating efficiency and flat spots. this technology(variable length intake) is already there in your IS called ACIS. below is a copy and paste from wiki "There are two main effects of variable intake geometry: Swirl Variable geometry can create a beneficial air swirl pattern, or turbulence in the combustion chamber. The swirling helps distribute the fuel and form a homogeneous air-fuel mixture - this aids the initiation of the combustion process, helps minimise engine knocking, and helps facilitate complete combustion. At low revolutions per minute (rpm), the speed of the airflow is increased by directing the air through a longer path with limited capacity (i.e., cross-sectional area) - and this assists in improving low engine speed torque. At high rpms, the shorter and larger path opens when the load increases, so that a greater amount of air with least resistance can enter the chamber - this helps maximise 'top-end' power. Pressurisation A tuned intake path can have a light pressurising effect similar to a low-pressure supercharger - due to Helmholtz resonance. However, this effect occurs only over a narrow engine speed band. A variable intake can create two or more pressurized "hot spots", increasing engine output. When the intake air speed is higher, the dynamic pressure pushing the air (and/or mixture) inside the engine is increased. The dynamic pressure is proportional to the square of the inlet air speed, so by making the passage narrower or longer the speed/dynamic pressure is increased" this valve might or might not enhance the IS but hey its your car so if you want to give it a go feel free to did it and you can always reverse the process if it ends up not doing anything performance wise.

come on intricateweb its only 2 miles per gallon difference between the two cars.. i think RX400/450h fuel tank holds a total of 65 litres (14.3 gallons). if you average 30mpg in the RX450h you will travel a total of 426miles on a full tank... if you averaged 32mpg in the RX400 you will travel a total of 457miles from the same full tank. now thats a difference of 31 miles between the two cars which is roughly the miles the RX450h does to 1 gallon. petrol is sold at 1.34p per and 4.54 litres makes 1 gallon so this works out at £6 for the extra 31miles needed to travel in the RX450h to meet RX400's total of 457miles. I dont think an extra £6 for a full tank will break the bank although i agree it does add up over a year. worth checking your tire pressures as sometimes a lower tyre pressure cases the engine to work slightly more than it should to move the car I know some car owners drop thier tyre pressure for a bit more comfort but that could affect mpg slightly. you could also get rid of excess weight i.e stuffs in the boot you dot really need for your daily journeys and roof rack thats if you have one. I personally will chuck in the extra 6 quid and enjoy the car for what it is :) . hope this helps.

my IS came with Pirelli's P Zero rosso's when I got it and they are quiet good in thedry but wet doesn't grip as good... but again why would one want to drive like Hamilton in the wet anyway just take it easy on the throttle and you will be fine...noise depends on the tarmac I am driving on..its quiet on a freshly laid tarmac but slightly noisy on an old tarmac..then again they are 18" low profiles so will be inherently noisy... mine will be due changing in a few thousand miles and I'm torn between bridgestone potenzas, Toyo Proxes 4 or Yokohama Parada Spec 2 all are established Japanese Performance tires which comes in most performance Japanese cars..decisions decisions..... blackcircles seems to be cheaper than most i recon

+1 Bobi :D ... I mean 145mph arrives so quickly it feels like its got more than just 210bhp when in PWR M mode OK its no ISF when not boosted but it surprises a few cocky BMW/Audi drivers who think UK roads was built for them alone..I think Lexus made the trans so perfectly they knew a manual will not be needed when it was first launched into the market although manual was introduced to the US market from 2002 because customers complained BMW330i was offered in manual so Lexus wanted to shut them up but I for one are not missing manual trans yet.

as a test, i waited for my fuel light to come on and filled up £40 worth of Shell V power friday at 142.9p per litre which works out around 27.99 litres (6.1 gallons). reset my trip computer and drove a total of 185 miles before the light came on again. around 40 miles was town driving involving stop starts between car wash and grocery shops. 145 miles was done on the motorway with cruise control strictly set at 70mph on my speedo guage and 65mph showing on my GPS sat nav. during the motorway cruise my nav was showing and average of 33mpg I thought this cant be right as at one point i had to put my foot down to 100mph briefly but 98% of the drive was done by the car at cruise control.. got home, and trip computer was showing 185 miles i worked it out by dividing 185/6.1 i.e 185 miles against 6.1 gallons and got 30mpg not bad if you consider its a 3.0litre automatic 113,000 miles 10year old engine. which concludes driven sensibly, it can achieve IS200 manual/auto mpg figures even with more go under the bonnet...

auction or we buy any car .com but dont expect to get £3000 for it as they will need to sell it on to make some profit but you can get a quote online . maybe someone on here looking for a sportcross might be interested worth advertising it.

yeh i wasnt too sure about the auto when i was looking to replace my V6 ford Cougar but after driving manual boxes all my life i wanted Tiptronic auto for a change and i must say this autobox does not lag behind OK you dont get full control of the car like a manual box but the buttons on steering makes up for it and takes little practice to get the hang of especially when to time it for attacking tight corners etc .. good thing i like about them is it stops you from abusing the box i.e. you cannot start from 1st gear or over rev it as it will shift up at red line and wont allow down shifting to lower gears when travelling at high speeds.. and if one is into thier mods these boxes can handle power exceeding 300bhp in stock form and when the valve body is upgraded, over 500bhp can be chucked through it and it will hold..mind the gearbox is the same one in the GS430 /LS430 so are quite strong... IS300 is a totally different car to IS200

NICE... :winky: !! the newer IS looks bloated compared to gen1 IS but with over 200bhp dual exhaust, sport body kit, xenons, sport suspension which handles top class, why not?? bet you cant wait!!

they are lots of IS200' about for that price range so i would look for another which is not throwing codes. a car throwing codes might be a sign of big bills coming your way but thats not always the case. personally i would stay away from this one.

looks like you winning Steve maybe because it wears a Toyota emblem and not Lexus they dropped the insurance group with the perception of it being 'just a Toyota'. this shows how flawed the system of working out car insurance is in the UK even tho the Toyota Celsior has the same engine, gearbox and body shell as the Lexus LS400. I bet a Toyota Aristo V300 Twin turbo will be cheaper to insure than say a GS300/430 even though it makes more power and torque than both.. maybe i should start looking for one myself.

I know what you mean about being dissapointed when a new model comes out with all the newer '007' gadgets but will boil down to how long you looking to keep the car for.. gadgets are exciting to have but will wear off after like six months of owning the car ounce you have experienced it and most import will be how the car drives, makes you feel and how easy(reliable) it is to live with and if economy is top of your list aswell, will also be how economical it is...that BM looks nice Andy..and every one knows they can handle really good on the limit when pushed hard but the gen2 IS has caught up in that department but still lacks a lil bit..I will say drive the IS aswell for 24 hours and compare what you get for your £££ when you go for IS and what you get when you go for the BM.. and go for which ever gives you more for your buck..would also be worth asking Lexus what kind of gadgets the newer IS would have but my guess will be it would come with the same gadgets as the top line 2012 GS250 F sport so i doubt it would have anything newer than whats already in the GS250/GS450h F-sport. choice is yours really..

what are you waiting for Andy? if its the IS-F or BMW you want and currently have the funds for it just get it... yes when a new model of any car is released the current models do drop in prices but not much i.e. we are not talking about a 20K drop in price when say a new ISF is released by Lexus tomorrow. all cars be it luxury or non luxury devalue as the years go by some do devalue more than others but they all do either way. LS430 back in 2001 was around 70K before you can drive one and can now be picked up for around £4-£5000 after 11 years. C63 AMG Merc was 70K in 2008 and after 4 years they can be picked up for around £25000 so regardles of what you drive your car will certainly devalue. just go for what you like if you can afford it today.. I would.
