Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Reported cause · Original poster
The noise sounds like it is coming from the windshield area, and is caused by the higher velocity of the air moving over the car when driving over 85mph.

I think it could be coming as a result of the spoiler changing the air flow over the front hood.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Are there any other 911 Cab owners that have had to deal with a "whistling noise" when driving above 85mph? If so, could you please let me know what was causing this noise, and how you were able to fix it. If not, do any of you know what might be causing it? Thanks in advance for your assistance. The noise sounds like it is coming from the windshield area, and is caused by the higher velocity of the air moving over the car when driving over 85mph. The whistling noise occurs regardless of whether the top is UP or DOWN. The only modification to the front of the car is a TechArt front spoiler lip, but the whistling noise does not sound like it is coming from that low on the car.

POST 2Original post

I think it could be coming as a result of the spoiler changing the air flow over the front hood. The front hood can be adjusted to sit flatter (when you click it down) so you may want to try that first. Think of the gap between the hood and the bumper as creating 'lips' that can whistle. I used to have this problem on my Boxster S and the problem was resolved very quickly by the service tech as I stood watching. Now mind you, I did have an OEM bumper but I can't imagine that TechArt isn't super good quality so this shouldn't be an issue.

POST 3Original post

Isn't 85 mph over the speed limit?

POST 4Original post

the whistling sound could be coming from the Highway Patrol.

POST 5Original post

I also had the "hood whistle" on my Boxster that nycebo mentions. Eliminated by adjusting the leading edge of the hood lower than the adjacent bumper cover elevation. About 1/8" to 3/16".

POST 6Original post

Mine whistles too but it is my wife simulating police sirens from the passenger seat...usually happens around 90mph. I would fix the problem but it would be too expensive!

POST 7Original post

Might just be people on the side of the road whistling "WOW" as your car goes by....
