Whistling noise at 120mph

Well i just got some new tires,Michalin pilot super sport, Wow what a difference. So much smoother at speed. Anyways I get a whistling type noise at speeds over 100mph. Almost sounds like an arodynamic effect or it could be tranny, 99 coupe with 70k. Any body else experience something like this? Or ways to narrow down where it's coming from? Thanks Fred

Wind noise at window seals?

Cops?

That would be my guess as well... Push out slightly on the windows and see if the noise changes... That will give you an indication if it is the window seals. Though you probably should have a passenger do it, as you'll be going 100+ mph ;-) You could also pull that front license plate and see if that is making noise.

On my car it was misaligned hood -

Mine makes noise on the driver side. I chalk it off as the price of a $5000 996

Thanks for the input, hard to do much but drive at 120, but will let my partner lend a ear, really got yours for 5k, Prob old news but I'm new to forum, well anything possible in Canada, Land of the free

You need more data points. What kind of noise do you hear at 170mph?

with these new tires I would be comfortable going that speed,I think, just to find the road that is long enough

No thumping noise at 170 mph? That would be my heart. My fear is going directly to jail on public roads at that speed.

My bet is on window seals too. If it only happens at high speeds, maybe have someone tape the window seal area with painters tape after you get in and go for a drive. It's amazing how little of a deformity you need on the window seals at those speeds for air to leak in.

You're that good? Hopefully not on public roads.

At 150, I heard the sound of my water pump bearing failing. Bummer, as I had one more gear. Unless you spend a great deal of time at 120, I'd probably let it go. But that's just me.

I would leave it as is. That way the whistling noise will indicate to you that you are speeding. It could be a window adjustment or any small thing. If you had your window open then it might be the wind passing over your left ear like when you blow across the top of an empty bottle . So pull you bob cap over your ears.haha

They just impounded my Porsche for 7 Days. 360$ ticket, for excessive speeding, 155 in a 80 zone These are kilometers. I guess a whistling noise is the least of my worries. Yes I'm a fuc*in idiot. well time to slow down.

The whistling sound was sirens chasing you the last time as well?

"But officer, I have this whistling noise at 120..." I really laughed hard when I read the last post on page 1. Feel bad for you man, but seriously funny.

Well, if it only whistles once every seven days, it's probably not worth tracking down.

Worst part of the story is,I was going to take the Porsche to Vancouver airport today, pic up my girlfriend and head to the ski resort Whistler, 1.5 hours of beautiful curvy roads and spend the night in the Hilton, Using her Hilton points. Right now im in the ferry lineup sitting in a Ford explorer

You can still drive fast... just go to the track! I've gotten to the point that I no longer use my radar detector in my 996 and I rarely exceed the speed limit by more than 10 mph. Porsches attract too much attention from the police.

best. thread. ever.

When I hit 100mph or there about, I hear what can only be described as a piercing shrill type scream noise. Around 150mph there is a very strange smell and I am damned if I know where that is coming from. Stranger still is it only seems to happen when the wife is with me.

Lol on the wife but the piercing shrill is probably the Porsche emblem you have back there. The 996 model was never aerodynamically designed to have more than a 3 letter emblem back there.

...and the smell is likely the combination of adhesives curing on the vast collection of numbers and letters stuck to the decklid.

That last post on Page 1 by OP was one of the funniest I have read in a long time, but then again, I wasn't the one with my car impounded. I feel sorry for you man. I believe that speed converts to about 96 MPH in a 50 zone in the US. While obviously pretty fast, that speed would not be considered that unusual on US Interstates although those speed limits on those roads are usually 65 MPH or higher. That said, it appears you guys north of the border take speeding pretty seriously. I have to believe there are very few states that would impound your car in CONUS. Good luck man.

96MPH in 50MPH zone would be criminal speeding in any state in US. Doing nearly double the speedlimit can warrant wreckless driving charge and license suspension as well. In the context of this thread, it is just too funny though. SM: Officer, I was trying to replicate that whistling noise I got last night at 120MPH so I can better describe it on the forum. Officer: *slowly pulls out the big black baton and hands SM a jar of vaseline*.

The speeds are in kph? Because I had very little whistling noise at 120 mph. Of course the roof was open and the windows were down. One bright spot in a day trapped doing lawyer stuff.

OP needs to move to Utah or Montana.

Ha ha. all these replies make me laugh, its good and entertaining. I usually know when to show and when to fold, this time i showed at the wrong time, first ticket in two years but i have ripped my sport bike in the same spot at the same speed many times. I don't really live in a conservative manner I am lucky i got no license suspension and only 3 points against my license, 6 points in a year and you get a 300$ fine here in BC, I could have gotten more chargers I'm sure, but the cop became my fest friend very quickly, One good thing, the tow truck driver, he brought truck at first, then flat deck after, also has a 996, a 2000 left to him from his dad, same color etc, so we chatted about the cars and he showed much consideration setting my car up for tow. no i don't have the tow screw thingie. Im sure we have the only 996's in a 100 mile radius. gotta look at he bright side at least i didn't crash the car or kill myself

Not in Pennsylvania. There is no charge of "criminal speeding" in PA. That speed would result in a very high fine and undoubtedly a suspension of your driver's license, but not reckless driving nor impoundment of your vehicle. I have to believe some other states are similar to PA.

They impounded the car but didn't suspend your license? That's weird. I used to heavily abuse the insanely low speed limits around these parts but a combination of experience, fear of cops, and been there done that keeps me below 160 pretty much all the time now. In my car anyway. I'm still pushing it on the bike now and again. What road were you on by the way?

Yes, glad they didn't suspend my license. Not sure what the laws are regarding license suspension I live in Gibsons, 40min ferry ride from Horseshoe Bay, I was on the only passing lane between here and Sechelt, the other small town 40 mins away, Finally got a chance to pass that minivan that was holding me up. I always get stuck behind minivans There are some great twisty roads farther up the coast, a good hours worth

For me the whistling started at 135-140 up the back straight at Watkins Glen. I suddenly realized that the bus stop was coming up and I was whistling Dixie!

So you're driving/riding in BC in a known spot for impounds - with our stupid impound rules - pls tell me you were bright enough to have a radar detector on???

All of BC has the same impound laws for excessive speed, 40k over the limit. I do have Radar, but was far too late, going around a corner at 96mph into oncoming police car.

I run that fast or faster and my detector picks them up every time??

Nothing can pickup instant on if there are no cars ahead of you or roads are sparse. Not saying that was the situation with OP but the one thing detectors will fail at.

Radar works like a flash lite . Detector will detect the beam but not if you are around behind or coming around a corner. Van island highway has some great straight stretches I'm sure but I usually only push it in the corners with the 996.

RCMP only run KX and KA in their cruisers. Good Escort (Solo III or 9500i) will pick them up every time. No excuse for the OP to make this mistake in this province when we are allowed to run these systems legally!! BTW I only run on the B roads with the 911 and my R1 and Duc - mounties never get close the detector always chirps and one touch of the brake lever and I'm at the limit. You've got to know how to speed in this provice - like not on the S2S etc!!

This is too funny

Is your neighbor missing their parakeet?

I believe that there is on the market a head light darkener which reflects the detector back to the cops at a slower pace, giving the driver more time to react in braking. By the time the cops get their reading you should be warned by your own detector of their presence and have come down in speed considerably. The cops train their beam on your head light reflectors from all accounts. I try to follow close to the car in front if I am speeding hoping he gets done before I do haha. You have to have your own police radar on board obviously. God only knows if this really works. I guess we will never know.
