Hi,

since a few weeks, I am missing this hard kick when I go at full throttle in the first 2 gears...do you know what I mean? When I suddenly accelerate at 3000 revs in 2nd gear, I used to feel a real hard KICK...the transmission probably also felt it...:) It was always there when I did let the boost increase slowly and then fully stepped on the accelerator...it was really a hard KICK into my back!

What could have happened? Now there is no more kick....the kick was also there when changing gears, for example when changing from 1st into 2nd gear at 7000 revs and the very quickly going again on the throttle...now this is much smoother, but also very unspectacular.

Could it be the clutch which is slipping and not transferring all the power to the transmission?

I hope that you have understood my problem, even if it is quite difficult for me to explain it in english...

Thanks for every reply!

Maybe clutch slip or loss of boost pressure. Get a boost gauge on there !
Apart from being a cool accessory, it is also an important diagnostic tool.

6LX,
Cud b fuel quality , have u changed the type of petrol u use?

Loss of boost is most likely caused by the wastegate actuator failing or becoming weak , or the dump valve leaking , if u have a boost gauge this shud b obvious.

Check the easy stuff first tho , fuel then leaking dump valve.

thanks guys for answering!

I do not think that boost has decreased...it is only this sudden kick at the moment when stepping on the accelerator, this has gone....the acceleration itself is as usual...strange!?

So, it could be the clutch? Do you know how much they can demand for an new clutch at my Mitsu garage, approximately?

oh, another question:

what is a flywheel? I read this term in another topic dealing with clutch problems...probably this part is damaged...?

Is there someone who could tell me how a flywheel is called in GERMAN so that I can tell it to my mechanics at the garage?

Thank you very much for your help!

EvoLX,
A flywheel in german is either 'die Schwungschiebe' or 'das Schwungrad' and is the wheel that smooths out the power delivery from the engine. It is this wheel that the clutch joins with to get drive to the wheels.

Hope this helps

throttle stepper motor,if a long way out gives exactly these symptoms
the power is there,but delivery has changed,you have to work it to get the same grunt ...yes ??

@Andy:

Thanx for the translation! But, if this wheel is responsible for the smooth power delivery, then NOW it seems to be working and BEFORE, when I felt this HARD KICK, it was not working...strange...this part was never changed or even touched. Nevertheless, I miss this kick, this aggressive first moment of acceleration, even if it felt very unhealthy for the transmission...

@Mouton:

What should I work on? Sorry, I haven´t really understood what you meant...But you are right: power has not really changed subjectively, but the feeling of the power delivery has completely changed...i beleive that the clutch and this flywheel have some trouble. Next monday I am servicing the car at my garage and I would like to tell them something concrete, because the mechanics there have obviously never driven an EVO and have very bad knowledge about these cars.

Perhaps its just getting used to the car ,drive a really slow motor for a week and then get back in the Evo the kick comes back.and is exiting as ever.simple things cause more agro than the big ones.

6LX,
Try this 2 test 4 clutch slip ,
Drive along a long straight road that has an upward gradient , get in2 5th gear at about 130-140 kph steady speed , then floor the throttle.
If the engine revs increase suddenly without a proportional increase in road speed the clutch is slipping.
Because the clutch spins against the flywheel face , if it has been slipping 4 a long time the flywheel will probably also need replacement because it will b damaged by heat.
Personally I don't think it is the clutch.

EVOBOY: alright, I´ll try it tonight...

SHORTY: I now what you mean, but thats not the problem. I do not say that the car gets slower and the acceleration kick has gone...no no, I really mean the KICK or perhaps the word is wrong, I mean this JERK, JOLT, this ABRUPT STRIKE when the BOOST smashes on the transmission.

To illustrate it: I drive at 2500 revs in 2nd gear. Then I slowly increase revs up to 3000, I can feel boost coming. Then I take away my foot from the pedal and VERY VERY QUICKLY step again on the pedal. Then the boost is already high and the power is delivered abruptly to the transmission not as if I would have accelerated from 2000 revs upwards which would feel more smooth because boost increases continuously.

Try it once! Accelerate slowly, then foot away from the throttle and then really fast again on the throttle. It is only a moment of 1/100 second but feels brutal. Now its gone :(

drive with part throttle,
as the boost comes in,with quite a pronnounced hit,the car runs away with itself for want of a better description, with the same throttle position

is this what is now missing?
if so ,it is the throttle stepper motor,which can only be set up with the mut2 (a ralliart or mits garage)

MOUTON:

yeah, I think you got it! My problem would be solved if I could tell the mechanics how this motor is called in german...anyone any idea?

Evo6lx,

Blimey that is a problem ,get it straight to the mechanic and sod trying to explain it .Fk asking questions about whats wrong ,if you notice any difference and you can't do it yourself get it to a recommended Mitsi specialist.
SteveHill motor sport or MADevelpopments if your down south or RC develpments and Ralliart if your midlands and up north.
I don't ask questions I just get it sorted .

SHORTY:

hehe, u r funny! I am from Austria and THERE ARE NO EVO SPECIQALISTS IN THIS BEAUTIFUL COUNTRY! The mechanics at my Mitsu garage (which is by the way the general Importer for Ralli Art cars in Austria) HAVE NEVER DRIVEN AN EVO...last time one said to me: oh, what a funny lancer, how much did the spoiler cost?

I am really not a specialist and I have only little technical knowledge about cars, but the mechanics at this garage are worser than me! Unfortunately this is the only official Ralli Art dealer in Austria and I don´t know where I could get better service :(

Scoobymike: thanx! are u from germany?

Sorry for the country origin mistake ,perhaps you can organise your servicing around a holiday to the Uk?:)Trouble is you'll end up a uk resident .
Are there any Rally prep teams around your area?Most overhere tend to put their car with more knowledgable mechanics.If there is any one who does alot of turbo work they at least would understand the engine .
Like you I have neither the time or the inclination do work on the car .when I looked under the bonnet [hood]for the 1st time .I thought great the car has 2 radiators ,I guess because if one fails there is a back up:D
Good luck in the quest for a good mechanic/workshop.
Its easier to pay others for things we know bugger all about.

@shorty:

good idea, I will look for some rally teams here, they will probably know more about 2 litre turbo engines...u are really lucky to live in the UK, that´s EVOLAND!:) In Austria people are more into Audi S3 and the TDI stuff...Japaneese turbo cars are more rare than a Ferrari here. Could be a good business idea to start marketing those jap cars and tuning parts here, who knows...

Evo6lx.

Were just lucky we never gave up the right hand drive.I'm sure some where in Brussels they are scheeming to take over and make us drive on the left.
Good idea to sell jap spares in Austria .Have you thought about this seriously:) you'd sell most of the stock back to yourself :D.
Must be nice to drive up a windy mountain side ,Have you got a ski rack on the E6? Evo's have tow bars over here to tow the holiday caravan around.This is why alot think there cars too slow.
