Hi Guys, I have seen ... and no doubt so have you, the advert for the new astra VXR. My question is.. what is Overboost? the advert for this VXR says it has an 'overboost' feature. from reading posts my understanding what this is a fault not feature?! however after a bit of googling found that its a point when the turbo can momenteraly force more oxygen into the chaimbers thus giving an 'overboost' above its normal operating spec?! another question regarding the turbo on the S3.. i have read a post saying that the boost dies off around 3000rpm and this is an 'issue' my car has always been like this. i guessed it was the lag while the turbo spooled up - learning to drive the car poperly you can always be in the 'boost' is this the case or does it need looking at. ta dudes.
