Tjaba !

Någon mer här på forumet som råkat ut för detta ??.Klipper in en Eng. förklaring på syndromet.

”The surge appeared between approximately 3000-4000 rpm and from 4000 rpm onwards it disappeared. This was both extremely audiable from both inside and outside the car, which sounded very similar to you trying to breath in through your mouth nearly closed and then quickly moving your tongue backwards and forwards from the opening (sounds weird, but gives the same audio effect). While looking at the boost gauge as the car was being run on the rolling road, it showed the boost very rapidly fluctuating around the boost target through this same rev range and then settling from approximately 4000 rpm onwards.
Surge is not a good thing to have, as not only does it not sound very good, it hampers the boost stabilisation and can have a detrimental effect on Turbo life.
For background information, Surge is caused by the inability for the engine to consume the air produced by the Turbo at a given point. Normally (obviously dependant on amount of air and at what rpm the Surge happens) the engine can consume the increased air further up the rev range, as the engines cams and valve usage increases allowing more air to be consumed. When Surge occurs, the Turbo compressor produces more air than the engine can consume, which causes a backup of air at the intake which actually creates reverse-flowing pressure waves that can be very damaging to the turbo.”

Undrar därför att min GT ’nyser till’ i bland på de högre växlarna
Problemet uppstod sen jag monterade dit decat-sektionen på 3 ”systemet. Bilen rycker till lite och ’nyser’ och varvar sen snällt vidare.Bilen är Tek-3ad.

Någon som i så fall vet hur man kommer runt det ?
