yeah it sure helps but i wont increase the boost..0.3 is max, the pulley cant make the charger spin any faster than it already does. one more thing if you dont mind...when your car is running in idle and you close the bypassvalve by hand, can you hear a leaking/sucking sound ? i still have that sound in my intercooler

Your boostgauge is showing i little high i think...the standard pulley would not make any more than 0.3bar i think but if you reach that in first and second gear and i dont it must mean i still have a leak or my gauge is showing i little low i must try an other boostguage to be sure anyway thanks for looking it up :)

Hi Dimitris i have one question for you What boost du you have when you put your foot down in 1 and 2 gear ? on mine it is around 0.22 in 1 and 2 gear and 3 4 5 6 it peaks at 0.3 when going full throttle that is is this about right ?

My Intercooler had seen better days..3 small holes at the back near the pipeconnection right hand side. a friend of my welded it and voila 0.3bar of boost but not in first or second gear what i can see i have more boost now thats for sure but i dont know if everything is ok yet gonna take it for a spin at night when the tempratures is low to see if the problem appear again.

yepp it is connected to the right one i did a little check under the bonnet just a couple of minutes ago and i let the car run on idle,,i closed the bypass by hand and not with the throttle and a strange sucking noise appeared down at the intercooler just by the pipe connection.. the car would suck air through the whole pipesystem when i close the bypass by hand right ?? if so there must be a intercooler leak as the sound appeared there...i could make a clip of it if it would help.

Surely if its temp related then thats the most obvious culprit? there was another member a while ago who had issues with that. I dont know but for the last 4days 0.2bar boost is dissapearing at evening and night..in which way would the tempsensor affect the boost ?? it´s main purpose is to ease coldstarting and adjust revs when the engine is cold ?

Here is a pic of my Lex with the boot lip spoiler fitted, and yes i have raised the coilovers by an inch for comfort my boostproblem is still there,,any ideas please write in my tread http://www.lexusownersclub.co.uk/forum/index.php?showtopic=66856

No i dont think so...cant think of it to affect the boost did a quick check on the intercooler and the right side of it is dirty and the left is clean..possible airleak planning on doing a leaktest on the intercooler and the pipes that connect to it..wednesday or thursday maybe if we dont find any leak i dont know what it could be. Is there an email or something to contact TTE ? cant find anything on there site besides contacting local Toyota dealer

There is a sensor connected to the Airbox...is that the one you mean ?

It seems like the problem is tempraturerelated the car runs fine at day but loosing atleast 0.15bar at evening/night Maybe a small intercooler leak ?? metal expands when it gets hot and maybe that is enough to keep boost at daytime and at night when tempratures drop by atleast 10degrees the metal dont expand that much and therefore leaks planning on pressuretest the Intercooler or simply just replace it with a straight pipe and take a testdrive...if it keeps boost then the hunt for a new intercooler begins thoughts about this ??

My airfilter was very dirty so i replaced it with a new one,,the boost was almost 0.3 after that for the whole day the car run great BUT at evening/night the boost dropped to 0.1bar again ! if the temprature goes under 10 degrees celcius the boost drops it seems.....

Sorry i forgot to write that i checked the belt and i cant see or hear it slipping..it is a 790 belt and i also sprayed some belt-grip on it The T piece is tight and intact i assume that the throttlecable is working properly as the bypass valve closing and opening as it should Maybe there is some problem with the boostgauge but i feel the loss of power so the boost is too low

Maybe some of you have checked my project-tread but anyway i decided to start at topic about my little problem here goes For about 10days or so my boost began to have it´s own life..it never goes higher then 0.22bar usually around 0.19bar I cant figure this out so i hoping for some help yesterday and today my boost were at 0.22bar at day 0.1bar at evening and night.one time is was at 0 ! no boost whatsoever..I use a older Greddy electronic boost gauge Today i checked the bypass valve..it opens and closing as it should also checked every pipe and clamp ,,i tighten up some clamps, now everyone is as tight as it can be. tonight i checked all the pipes and connections with start-gas(dont know what you call it in UK) when the car was running at idle. the point is if there was a leak and the spray/gas hit it the revs would increase but they did not..there should not be a leak then, but who knows ? the car runs with low boost all the time but especially at evenings and nights it seems. Can the TTE Black box cause anything like this ??

No need to find one B) there is a 5PK790 fitted already Guess i have to wait for TDI to confirm my order for the siliconhoses,,but thesite seems to be down is there some other place that have siliconhose-kit ??

i could not see the belt slipping while looking under the hood when my friend gave it some revs. it seems ok but where do i find the 5PK790 belt ?? will the 5PK788 fit also ?? EDIT: is this the right belt ? http://www.amazon.com/Bando-5PK790-Quality-Serpentine-Belt/dp/B002EC9JW2 http://www.camskill.co.uk/products.php?plid=m28b805s2591p14337

A little update The M3 CSL lookalike wing is fitted and it suits the car very well..will be posting pics later on The boost problem appeared again..yesterday my gauge showed absolutely no boost at all, and the car felt slow today 0.2 bar as always and the car runs like it should ..very strange first step finding the problem resulted in an order from TDI, upgraded siliconhoses for the supercharger

today something strange happend i started an overtake and the car felt like a stock IS200,,the greedy gauge showed that there were boost but the car felt slow and almost had a hesitate feel...no ooommph at all over the powerband parked it for awhile and then went out for an spin again,,same old feeling and acceralation and no more stockish feel Any ideas what it could be ? the car runs great now

Atleast 18" dont have any suggestion but i would guess some deep dish alloys would look great if lowered properly and yeah ofcourse i love my wheels

Nothing much to dislike except three major things..slow even with TTE charger, thirsty !, and six gear is to short should have been longer ratio for motorway driving.

thanks ! that is great info :)

Just placed an order for a Blueflame exhaust later on i will figure out how to make my own intakekit as my is an LHD, cant buy an intakekit for a supercharged IS200 as everyone is for RHD and therefore the ABS unit is in the way for me anyone driving an supercharged lefthand drive IS200 with an custom-made intake fitted ?? please write as any idea how to make one is appreciated

I use Meguiers range of products the result speaks for it self

god i hope you not seriously thinking of fitting thoose wheels three spokes are the devils work...hideous

just bought two new 18" 245/40 tyres , my pirellis is slicks Federal SS-595

Thats nice to hear :-) might order the exhaust soon
