Fastest you've ever gone in a car?

RE: 500 mph but......

I was in the Mark with a couple of my boys and had the cruise control set at 115 on the highway the other night, yeah, we were in a rush...Concord to Manchester in 4 minutes...

But The fastest I have ever been going while I was in control was 2 days ago in a Mooney M20J Bravo. We trued out at just over 210 mph.

I call BS!

You won't see those speeds out of a M20. Now a 252, well its self explanable. But theres no way you got it out of a M20, regardless if its a Bravo. I can see a 210mph groundspeed, but your true airspeed shouldn't have been over 180kts or so.

RE: 500 mph but......

close...

1 knot = 1.1516 mph
180kts * 1.1516 = 207.288mph

and at 11,500 I see that as being very hard to attain. The M20's are N/A and they are going to lose power. The HP and most, not all of the performance specs are taken at sea level. Must be a very strong M20.

Remember driving up the Jersey Turnpike back in spring of 1957 in a '51 Ford. Had the needle pegged...twas a Friday morning about 10 or 11. A New Jersey Turnpike cop pulled alongside and motioned me to "comeon"....I didn't have any more to go. He squalled the tires on that Chrysler 300!! Followed him into a rest stop just to look at this car. He already had the hood open and the car just sit there idling...looked like it idled very roughly....raw gas was dripping out tailpipes. Had whatever engine was in those 300's that year (Hemi?) and a full race cam. He just chuckled.....

One of my uncles "back in the day" hahaha... ran out of gas one night on the New York state thruway and got a ride from these NY state troopers... he said he was white knuckled to the seat in the back of the cruiser. It was one of those big Chryslers as well... he said they did around 140 to the gas station and then back to his car... the whole time they were just casually chatting with each other about their wives etc...

its a Bravo. I thought that the Bravo Package included the turbo. Well, it has a turbo....

Bill, seeing as how you're a plane guy, I was travelling West to East in a 727(?) and the commercial pilot came on the P.A. and announced that we were going the fastest he has ever travelled in a commercial plane. I (think) he said 660 mph and that we were in a 115 mph jet stream. I couldn't really tell the difference between 545 and 660. My facial skin was rippling like a sound waves at both speeds.:7

Can you beat that? 660 is right up there I think for commercial jet engines with a little tail wind. Do you agree?

If it has a turbo on it then there is no doubt that that plane can reach those numbers.

I call BS on this one as well. My reasons:

1) That would make the plane supersonic
2) You would have a "sonic boom" (big big fine that the airliners won't risk)
3) Supersonic flight over the continental US is prohibited. (With the exception to military aircraft and those of us who don't mind paying a hefty fine)
4) At those speeds they would be endangering the lives of those aboard the aircraft. Boeing (you said it was a 727) does not give plaque card ratings to their commercial use aircraft to push beyond M.85. The plane may be tested and be completly secure at higher speeds, but those aircraft are not supposed to go over that point.

Now let me back up a few steps before I get pounded into the ground. The aircraft had a true airspeed of 545mph. Which equivlates to 495kts. Thats putting the true airspeed of the aircraft right up at the M.85 number. It is very possible that the aircraft may have done this. But I find it extremlly hard to believe the pilots/flightcrew/controllers allowed this to happen. Why do I say that? Because the airfoil (wings, tails, etc.) on an aircraft actually fly faster than the rest of the body. The wings will have a greater velocity than the rest of the aircraft. This happens because of a pressure difference. At the speeds you mentioned above the oblique and expansion waves would be getting extermly tight (meaning the wing would be very close to going supersonic).

I believe that the aircraft was traveling at a high rate of speed, but I don't believe the numbers you threw up there. Sorry :(

RE: 500 mph but......

I had to edit myself, so I will digress and start over.

This is strickly from memory, about 10 years ago. I take approximately 40-50 flights/year. Doesn't make me an expert in aviation travel. As you are, help me out.

What is the maximum speed of a commercial jetliner travelling at 32,000 to 36,000 ft?

Like I said, it believe I was in a 727. Take the maximum speed and add the 115 mph jetstream, and that was the ground speed number. I do clearly remember the 115 number because the pilot just crowed about it. I'm not trying to make a point here. Was simply sharing an experience.

Personally, I thought Bill might find it of interest and make a comment one way or the other. Couldn't help but post the latest records, all in April of this year. Maybe I can find in the archives the record that was set that day that I experienced.

Newest Records added:

30 Apr 03 B737-400 485 kts
25 Apr 03 A340-300 617 kts
24 Apr 03 EMB 145 590 kts
22 Apr 03 B737-500 500 kts

Airbus A340 doing 617 kts. What exactly do you make of that!

Also, I said I believe[u/] it was a 727 with a question mark. That means that I was not sure of the type of craft I was on. After 400-500 flights, please excuse the fog covering the exact details.

RE: 500 mph but......

Ok Bryan, my fastest was over 20 years ago in a C-141A coming back from the Orient. In the winter, the jet stream can get over 200 knots in places depending on the atmospheric conditions. We had recently gotten INS units installed in the aircraft and it was pretty neat to play with and see your ground speeds in a LED read out instead of trying to mathematically compute it. Anyway, on a cold winter day up in the jet stream at about 36,000 feet we got up to a indicate 620 knots ground speed at one point. The C-141 was Mach limited to .825 or 350 knots indicated at low altitude.

Another time in 1979 at a RED FLAG Exercise in Nevada, we pulled the over-speed circuit breakers in the cockpit and were indicating between 370 and 380 knots trying to keep up with a B-52G “Buff”. He had all kinds of good “jamming” gear to keep the SAM sites and F-5 “MiG” simulators off our butts. It felt like we were running over 20 miles of rail road ties going 75 mph in a car. The "Buff" was traveling well over 400 knots and finally just walked off and left us as those little fighters jump on us like hungry piranhas. Considering they still had to “slow down” to jump us it was kind of pointless. Your only hope is to run them out of fuel by staying low and fast and hope you got more than they have (LOL).

Indicated air speed and actual speed over the ground are two very things for an aircraft at altitude. With a strong enough tail wind you can exceed Mach 1.0 as a ground speed but still only going through the air at altitude at Mach .80

RE: 500 mph but......

Bill...So was this a good number that we were travelling at on a commercial airliner? I posted some of the records for this year. Do my numbers make sense?

What is the maximum knot speed of a commercial plane at 36,000?
What would that compute to on the ground with a 115 mph tailwind? Jetstream was travelling west to east.

Thanks for any clarity you can provide.

RE: Fastest you've ever gone in a car?

I just don't have the balls I used to.

But in the past...

97 Continental - seemed to cut off at 125mph :) I loved that car.

93 Mark VIII (old one, not this one) - indicated 140mph. Bad ass old car.. Nice burgundy in color, the original first gen directional wheels.. I loved that car.. Swapped it for the above conti at about 100k miles.

79 Tbird - (My first real car :), that ran at all anyway) - indicated 130 but I bet thats optimistic even though it had a old Lincoln 460 in it.

89 VW Jetta GLI 16v - 115 was all she'd do, unless you had a tailwind or a good hill to go down then about 125 was about it :).

The all time coolest car was a 85 VW Jetta DIESEL with the injection pump cranked :) Smoked like hell but would run a solid 100 mph with a REALLY steap downhill stretch. Got 55mpg to.

I ran the little Esprit up to an indicated 150mph somewhat recently, pretty damn cool. It still had quite a bit of steam left and was just so smooth to drive at high speeds. That thing is a ball over 120.. just so cool :). Smokes my coworker' Mikes Porsche 928S pretty bad in the twisties and on the straights. (http://www.928s.org)

I chased a fraudulent check writer in my Excursion awhile back to, that was cool. The school bus will actually go 100mph! Damnest thing I've ever seen. Good for a laugh. It needs a blower bad :)
