At around 150mph+ I get some sort of noise coming from the front of the car like wind is coming into the car from somewhere and when I first got the car evrytime I took a passenger upto that speed they said to me it sounds like wind is coming in through the window, would anyone know what this could be as it is really starting to pee me off!!!!!

Thanx,

Nick.

 

nick turn your radio up and close your sunroof............

 

LOL... It could very well be the seal on the upper part of your windshield, or a burnt out wheelbearing, is it an overpowering roaring sound as speed gradually goes higher?

 

It's God, telling you to slow down.

 

The sound starts happening at around 150mph and it is an overpowering humming sound that increases as speed gets higher!!!

 

Hmm weird, only at 150+.. Mine was from 60 on up, but my wheel bearing was shot i found out, could very well be the windshield, take it to a glass guy and see if there is a gap between the seal and windshield!

 

Sounds like it could be that!!!

 

I have never driven my car 150. Too fast for me. I will never hear that wind sound.

 

 

Ahh common, that's where the fun really start's

 

Now that's surprising to hear someone with a Turbo state they've never taken their car to 150mph... I could see perhaps on a sport bike being a bit timid of 150, but a 996 Turbo S like yours asks to be driven at those speeds.

 

Back to the subject at hand... I would have the windshield checked as well - that would be my step 1... You need to get that possibility out of the way.

 

I had it happen once at a little over 180, and it was the side window. Next time I opened the window slightly, and no problem. I never did figure out if it was internal pressure from the front vent letting air in the cabin (it was a dp935) or vacuum/low pressure effect from air traveling over the window. I know it was weird and startled the hell out of me. I have an old vhs video of it with my banker friend holding the camera.
