hello,
i read some post here before regarding , after new clutch being installed, the cars becomes slower as the clutch needs to break in.
i had the same clutch exchange, and on the way from the workshop the car felt really slower, no kick in by the turbo at arroung 3k to 3,5k rpm.
tested it today again, kinda still the same felling.
is it really about the break in the clutch for like 500miles, and my car will behave the same way as before?
thank you

 

The clutch install itself should have had no impact on the car feeling slower. A lightweight flywheel might make a car shift better and rev faster. Breaking in the clutch is really for the flywheel, pressure plate, and friction disks to bed into each other evenly and prevent uneven wear, hot spotting, bad engagement feel, etc. I also believe heat cycling the materials a few times before shifting aggressively helps with longevity as well.

I suspect that one of the intercooler pipes or turbo vacuum lines may not have been reinstalled correctly after the clutch was installed. I'd start with a boost leak test to debug that as a potential problem.

 

so ,i have an update. there were somehow multiple thing little bit not ok. blow off was very weak and not holding, ECU, was faulty and not reading the map correctly, + throttle valve was opening to soon and not fully.
all got changed, car is back where is supposed to be and right now its even faster than accually before, as i guess it was fading allready before the clutch exchange.
thank you guys for all your inputs. thank you.
