Hi guys!!!!!
today my dealer gave me my 997S with my Evoms SC!!!!!
When I gently accelerate from 2000 to 3000 rpms in 1St and 2Nd gear I hear from the turbine like a vibration a short one and then dissapears....
My local Porsche dealer install the kit with the instractions that comes!
they check and all was perfect but I dont know If the vibration is normal....
from 2000 to 3000 in 1st and 2nd gear....

I will appreciate your help....

 

What that sounds like to me is the top of the blower unit hitting the under side of the decklid. The dealer may have to do a slight modification to the decklid to give the blower more room so that it does not make contact with the decklid.

 

Thanks for your Help Nate.....
we drove with the hood open and the noise continue!!!
but when we open the hood...and accelerates the noise cames from the turbine!!!
is very strange!!!!
apart of that all is ok!
but I`m scared about that noise.......

 

Time to get a new motor....Jk

Thanks Nate...I will call you from my dealer....now here is 9:30AM and they are open up to 1:00PM.......
do you speak spanish?

Thanks!

 

its normal its the bearings..........or so i was told

 

Can you duplicate the noise with the hood open and in neutral? Maybe then you can better locate where the sound is coming from. Turbine noise is fine, but you should have no vibration. It may have nothing to do with the compressor.

 

so if the noise cames from the ball bearings all is OK!
the noise is when the car is in neutral (mine is manual) at 800rpm you car hear the vibration cooming from the charger and the in 1st and 2nd gear at 2000 or 2400 rpm and then dissapears!!!!

now i`m happy!!!!!!

Thanks for your help bro!!!!!!

 

You will hear a rattle at idle, but once under load, the sound should change to a whine which will progressively and linearly change as engine speed increases. There should be no hicup or other change in the whine while accelerating. The sound of the blower is very predictable as speed increases.

 

The bottom of the turbine can possibly hit the frame. Check the 6 o'clock position on the turbine. Take a 1 inch section of a rubber hose, like a radiator hose... cut a slit down the side so you can open it up and essentially make a rubber square out of it... slide it under the turbine... it will be tight... and you likely won't have a rattle any longer. Lemme know.

 

Oh, and by the way, Nate's right. You can relax. Just find the rattle. Nothing's wrong. Take care, JC... Oh, why don't you go ahead and tell us how it hauls *** now?
