She has driven less than 5 times with me as a passenger in the car, always results in an argument about how she's too far over...or almost hit the guardrail...or changed lanes without looking....and she get's her skills from her parents.

up and putted around his neighborhood for a while and eventually swapped seats with him.

Could have also been fuel though, I was running higher test before I brought it back to Cali, threw on the 19s, and started pouring in the swill that passes for 91 octane out there.

Road Atlanta back straight - 158 (as apassenger in a GT3, w/ a Grand Am driver bud at the wheel)
Me personally: 149 w/ my old BMW E46 M3 (same place)
C.
265kmh on the 401 going east in Ajax at 7am on a Sunday morning. Sorry - not sure of mph conversion. The car still had room to go - I got nervous as the front end got a bit floaty.
161 mph at the start finish line going into T1 at Daytona. 154-155 going into T1 at Brainerd. Both were recorded on a GPS.
Chad, I'm guessing your 158 was on the speedo right? That's a fairly fast spot but 158 seems optimistic even for a GT3.
Jim
Yep...Same car, my Speed World Challenge driver friend (his car) got a touch over 160. Mind you the car is setup with Motons, etc. It is VERY well planted. In fact, I think he posted his findings on the GT3 forum. (look for Seth Thomas)
Scared the Be-jeebus out of me coming into T10A.

Considering that my 90-year-old grandmother could/would say the same about any of us that drive 80 mph on a freeway, I'll go with the term "ill-advised" in place of "retarded".
I'd be interested in knowing where the "retarded" cutoff IS...I'd bet my 996 that the majority of Rennlist members have taken their cars over 100 mph on public roads.
It's all a matter of training and conditions.
If you're not trained to handle a car at speed in the given conditions, then that falls into the retarded category, regardless of whether the speed is 100mph or 65 in a 55 zone.
There are days when driving 55mph in a 55mph zone is retarded.
Umm.. yes
All depends on the situation of course. I see cars FLYING by me, zigging in and out of traffic, heavy braking behind slower cars, etc.. those are the retards. Open road ahead with no interference, no problem there. I can stop faster from 100mph than an SUV can from 80mph, plus I can handle much better, so it's no big deal.
How much do you want to bet on that braking thing? You can even choose the SUV, provided it's a late-model vehicle.
Hell, my SO's daily driver SUV will outbrake my 996 from 60-0. I can't imagine the annihilation if you spotted the SUV 20 mph.
Most of the speeds posted here are probably just guesses anyway since the speedo on the car is VERY optimistic. I thought I was hitting about 160 at my fastest (back straight at VIR) according to my speedo but then my GPS data acquisition told the truth after I uploaded the session. 153 was the result and to date my top speed. That is in my GT3 with stock suspension. I'm looking forward to see what it will do once the new suspension is installed! Currently in the shop getting a total suspension upgrade from the ground up
Got talked out of it from several of my good friends that I run with at the track that have kids as well. They had the same thoughts in those early days like I did but when you realize that you CAN have a life and should outside the home then you quickly realize how much joy this hobby brings and keeps that whole equillibrium in check
Man, did I just try to pass off that line of bs??? I had myself believing it for a sec! Seriously though, there is nothing wrong with loving your child and still loving the hobbies you have. Mine just happens to be one where the family can be with me. My wife tracks the car (well she'll get back in the saddle when she recovers) as well and I have always seen lots of kids in the paddock. I just need to make sure I have all latest and greatest safety equipment and at the same time realize that I have a child that needs his father and not to do anything stupid on the track that would put me in a bad position. I pride myself in my skill and awareness on the track and would like to think I can continue this hobby without a worry in world.
I might want to take that bet myself. C&D tested a broken in 1999 C2 from 70-0 in 163 feet. A Range Rover Sport and an X5 will come within five feet of that, but not better. A Cayenne is, like, two feet better. But a Grand Cherokee needs 195, and that's typical of Detroit iron. And those are test numbers. Nice straight lines. Add in the fantastic modulation in these cars versus what it's really like to stomp on the binders in a panic situation in an SUV... and I even get to choose the SUV? Yeah, I'll take a piece of that action.
Motor Trend tested the heavier version (FX45) of my own SUV at 115 ft from 60-0, and an '03 C4S (I have a '99 C4) at 112 ft from 60-0, so I know there's plenty of SUVs out there that can keep up. A Ford Explorer is in the 130 ft range from 60-0.
So, yeah, it's not "all SUVs", but an awful lot of them (Cayenne, FX, SRT8, RR Sport, X5, probably anything from Mercedes, and a lot of bread-and-butter American iron) sure could do it. Also, we're not talking panic situations--we're talking straight testing. There's no doubt in my mind as to which vehicle I'd rather be in for a panic stop situation, but that wasn't the point.
I had my car flat out at 177 for a while on Rt. 17 upstate NY at 6 a.m....not a soul on the road...even the wildlife was sleeping. One of those several mile long dips where you can see downhill and uphill for miles. TOTALLY Kidding.
I did flirt with 150 for a milisecond when I first got the car, just to ensure stability and satisfy my curiosity...it got up there so fast, was really cool. Major adrenaline. I will never even come close to that again off the track, however, I do hit triple digits occaisionally when it's open ahead. It's amazing how going in the 90's in this car is so smooth and easy. My bimmer did the same thing no problem. Around here...if you aren't doing 80...you get rear ended.
No flaming please....I'm a grown adult with plenty of track experience and common sense.
Best,
J
Retarded is a bit much doncha think.
Figure this, a German regularly goes 250 kmh+ on the autobahn, in traffic, in a Peugot sedan.
So now a Rennlister goes out on a deserted stretch of highway, in a Porsche, and does the same. How is this retarded? OK maybe ill advised, maybe even risky..but retarded? Get a grip.
FWIW I did hit 163 (indicated 168, but radar-checked) at the last Silver State. There's not a lot of acceleration once you change up to 6th at 150-something
Germany = Better trained drivers on better quality roads, surrounded by better trained drivers.
Over here it's typically the case that even if you're a good driver you're surrounded by unpredictable idiots on poor quality roads - that's why it's retarded to do triple digits on populated public roads.
Open deserted roads is a different matter, as you're only putting yourself at risk.
Personally, I don't do early morning speeding, as you're likely to end up doing a high speed smooch with a seriously pissed off deer... but hey, it's all about personal decisions and responsibility. Whatever blows your socks off.
+1 with Wellard. While I don't necessarily think Europeans are better drivers than us...it is precisely the other "bad" and "unaware" drivers that always have me looking at the big picture when I drive. And when it comes to speeding...they are the reason why I don't "overspeed"...even if it's only one car in the right lane as I'm passing way left.
Most drivers are unpredictable and are often not paying attention. If most driver's were as astute as most of us here, then the accident rate would drop 90%. But that's not the case...nor will it ever be the case. And we all know who they are....my wife being one. She has driven less than 5 times with me as a passenger in the car, always results in an argument about how she's too far over...or almost hit the guardrail...or changed lanes without looking....and she get's her skills from her parents. She's just awful....that's why I have the best baby seats on the market. I just roll my eyes....I don't think she'll cause a big wreck or anything....she simply bangs up her car more than I could imagine. Last year...I just stopped fixing the van...it's got dings...dents...scratches on almost every panel. Never a new car for her again.
OK...enough ranting.
If there were better more aware drivers.....yadda yadda yadda.
J
Ouch! I feel your pain! I don't think I could be in the same car as your wife.
I have a colleague who is very similar - weaves like crazy in heavy traffic and doesn't look more than 1 car ahead. Every couple of years I make the mistake of letting him drive on a business trip and immediately remember why I don't normally let him drive. The only way to retain my sanity is to turn up the music, look out the side window and grit my teeth.
As for driver training - while it's the case that there are bad drivers everywhere, the quality of driver instruction and higher standard required to pass a driver's test in (most of) Europe (please discount France, Italy and Greece from this statement) does make for better and more considerate drivers. It's a night and day difference, as the lane discipline and predictability of drivers makes life a lot easier.
the one ton diesel stops more or less where i want it to. wouldn't want to be standing in front of it however. indicated speed whilst not really pushing it out of oak tree and on down the stretch was 139 at the entry to the braking zone of 14. i know there was much more available. just didn't have the cohnes to see what it really had. i was not in a p-car however. (ugly american plastic)
i may just go Cayman shopping one of these days.
+1 on driver training, in North America we need much higher standards.
As for a deserted stretch of road and planting the right foot or twisting the right wrist, yes, been there done it, guilty...
not often. It is amazing how these cars accelerate past 100MPH, and thats just in my over weight '03 C2, can only imagine what it's like in a very high powered exotic.
Having said all that it is stupid, any fool can plant the foot on a straight stretch.
Found out at my first DE it takes much skill and patience to go fast around a track and thats where it should be kept.
Kudos to those who have posted their top "track" speed.
Stay safe all.
Geoff
172mph on I-27 on my way to Sebring at 4 in the morning. Nothing to hit. No deer. Had cruise control set at 160mph and was curious to see how much faster the car could really go. It really starts to struggle past 167 or so.
190 (per the speedo) on 505 on the way to Thunderhill @ 6am earlier this year. Long straight divided highway with no traffic...except the two trucks hauling their cars to the track. (Didn't want to back off since I was losing a tailgater.) Talk about a wake-up call for them when I went by at ~triple their speed with my muffler bypass pipes!
Also done 180 there before with zero traffic early in the am on the way to the track.
My old '99 996 would feel a little loose at anything over 135 and get downright scary over 150 with the stock suspension, etc. Not the case with the GT3. It was rock solid and still pulling like a locomotive at 190. No issues whatsoever.
OK, now that it's safe:
150+ mph with a Pontiac GTO breathing up my C4 tailpipes on one of the rare lonely sections of I-80. I told myself that I'd let off when he did...
145 when in fifth gear, pulling away from friend's Boxster S, suddenly blowing my oil separator and creating a smoke screen behind me
I really thought my engine blew!!! My friends now call my 911 a BOND car and are wondering if next time I'll shoot rockets
P.S Thank god for extended warranties
>3 miles/minute gets your pulse up quickly. You become super sensitive to every feedback that the car is giving you (which is a lot in the GT3) knowing that any small issue may magnify immensely at that speed and could be fatal.
Tunnel-vision wasn't an issue. I'd gone near that speed before, so it wasn't new to me. It really hit me how quickly I was covering ground when I passed the trucks pulling the trailers. I had confidence they wouldn't suddenly do anything stupid since they're track vets and good drivers, but I don't think I'll be passing people at those speeds in the future...
I'm sure the speedo is optimistic (thank the lawyers), but it's a GT3 with 8,200 redline and peak HP @ 7,400. Top speed per Porsche is limited to 190 (they didn't want it to be higher than the more expensive Turbo, which is 191). I hadn't hit the limiter yet when it indicated 190.
it's funny i was searching for speedometer error and saw this. fastest GPS recorded speed was too high to post, speedo higher, but that GPS is no longer of this world. Is the there a consensus on the accepted speedo error +/- at stock rolling diameter? I feel like at 60mph it's about 3mph optimistic, by 100mph 5 or 6mph, but at higher speeds much moreso (+12 as per GPS). Obviously SIRF3 is not dead accurate either, no G-meters here.
that road has to be the fastest traveled in the US. F350s cruise over 100 all the time. It is also the most boring road. I will be driving it next week.
I did a true 160mph verified by GPS this past year in eastern Utah. My speedo said 167mph, and I was surprised I was still accelerating decently. I had recently installed ROW suspension and new wheels (not pictured) and it felt pretty good at that speed - but I won't be doing that again I don't think. It isn't often that you have a clear road ahead for miles and not a single exit/entrance ramp either - that stretch of interstate is one of the most desolate I've seen in the US.
Maybe my GPS is detuned! My speed to GPS error at that rate was +10. I am also rolling just a hair below stock diameter (still well within tolerances), which would definitely begin to show up there.
Comment about rear width vs drag, the car felt like it pulled a little faster at high speed on the stock 17s than on the 19X11s, but was much more fidgety than with big 315s. Could have also been fuel though, I was running higher test before I brought it back to Cali, threw on the 19s, and started pouring in the swill that passes for 91 octane out there.
Speedo is approx 5 mph optimistic on mine, compared to GPS
143 on I95 in AZ - going through the military proving grounds on a 10 mile straight
Had to back off - feared that wifey would damage the seats, she was gripping so hard! LOL
Isolated 4 lane high way goes nowhere to nowhere, 5 miles. Long story regarding court case 'cuz highway goes through breeding ground of protected pre-historic mosquito or something.
Anyway, after recon run one way, came back for the speed run. This was early in my car ownership soon after the break-in period at @2500 mies on odo. Redline 1st, redline 2nd, redline 3rd, redline 4th, chickened out and short-shifted 5th to 6th. Smooth, flat, planted at 168=170 MPH on speedo before this voice in my head yelled "Are you NUTS!!!!". Haven't done it since.
154 but it always reads 5 mph higher than the road side signs- no other car I have driven does this and it has the factory wheels and tires so myabe this is just a 996 thing? I dont remember my boxster doing this.
Yeah funny thing I noticed about the error in the speedo is that when I took my run at a radared and speed trapped 171 MPH my speedo read about exactly that speed, but at regular highway speeds (ie. 80 MPH) it is always a few MPH faster than reality. I actually took 3 runs that day that ranged from 169 to 171 and every time my speedo was pretty much right on with the official results. I'm wondering if the error actually gets to be less as you get going faster.
for me the error actually increased with speed, but I am a little smaller than stock diameter in the rear.
By the way I did check my notes and while I had remembered as a +10 mph error at 150-170 it was +6 to +7 mph speedo vs my GPS.
Without knowing the calibration of either instrument definitively, there's no real basis for comparison. I'm more of a mind to trust the radar trap
As the speed increases the diameter of the tires increase. At 170 you can get
2-3% more mph per rpm...
ps. I've had my 928 up to 190 on the GPS and hope to do a lot better this summer
with a 100 extra rwph
Just testing my2004 GT3 in Conn early AM RTE 84 no traffic saw 165MPH, and that was uphill. Stable as a rock and didn't want to end up in Jail so backed off at the top of the hill. Had plenty more RPM to Go !
Think I'll wait for track time in the future.
186 MPH, 993TT with 400hp : I-280 between San Jose and San Francisco
170 MPH, 996 C4S X51 with 400hp : I-85 between Mountain View and San Jose
Bottomed out at 170 on I-85.
Sudden loud sounds at 170 can change your driving habbits for a long, long time.
While living in Germany many years ago, had a Pontiac Firebird Formula 400 that I had up to an indicated 140mph on a downhill stretch of the autobahn. This was back in the '70's and it really impressed my German friends. Pontiac said the top end on that car was 135mph so maybe I was almost going that fast.
In Porsches my old 1970 911T used to top out around 125mph on the autobahn. All the other Porsches were in the US and I don't think I have ever had any of them over about 120mph. When I travel to Europe now, I usually end up with Audi A4's or equivalent BMW's or Mercedes which all seem to top out in the 120 to 130 range on the autobahn. I did get one of the new Audi TT's on a trip last year and got that up to about 135mph on one stretch of autobahn, but it felt a bit loose at that speed. One of these days I am going to splurge and rent a 911 from Avis. I always see them at the Frankfurt airport location, but they limit the mileage too much on them.
i did 285km/h at an empty highway with my 2003 C4, being followed...at a distance...by a friend with a 986S and further back someone dare to challenge and follow us with a 2006 SLK350. Both Porsche's were fully loaded (two persons with luggages). I must say i was VERY impressed with the stability of the car even at these speeds!!!My previous car was an Audi S3 with many modifications (even Porsche 993 Big-Red brakes, Bilstein PSS9) and i got it up to 265km/h but the C4 is a TOTALLY different experience!!!
Nikos.
In 1978 I got a new 911 Targa up to 145 mph on I-64 West of Richmond,Va.....scared the ______out of me. I was young and stupid!
In 2001 at Porsche Driving School I got up to 146 on the backstretch at Road Atlanta....that wasn't scary because I was on a race track and the 996 was very stable.
155 in 993 on highway between Annapolis and Baltimore with the top down which was a panic.....and 160 with C4S on Route 11 scenic Cherokee Foothills highway in the straights between Georgia and NC in SC...........regularly drive 90-100 around the perimeter in Atlanta where I live now....have to for the flow traffic.....crazy fast drivers in Atlanta....
Hi! Folks.
166 MPH on a highway near Madrid, Spain.
The car went absolutely stable and he could have gone beyond but the driver went a little frightened...
Not the fastest @ 125'ish but I bet the scariest...
The gentleman painting my vintage Mustang is a pretty good friend (we will refer to him as Jay Jr.). His 70 year old father (Jay Sr.) had just returned home from a stay in the hospital following a moderately serious heart attack. Jr. explains how Sr. had once worked for a gentleman who owned a P-car and that he had always wanted to drive one. I felt obligated to grant a life long wish for a man in his twi-light years.
Jay Sr. is a life-long old school hot rodder. He has built many a Ford small block V8 screamer (8000 rpm 300+ ci iron blocks) with power curves that felt like moon launches. I picked Jay Sr. up and putted around his neighborhood for a while and eventually swapped seats with him. I stupidly suggested he "put her on the highway" (I-675 SE Atlanta). Just after merging into the 70-80'ish flow a very red Corvette with a very loud open exhaust booms by...
Jay Sr. punches it! 90...100...110...120... His clutch work was club-footed at best and his steering inputs were vague. Evening Rush hour traffic was just getting warmed up (in Atlanta it starts around lunch time) and he seemed to be using the tires on the lane markers as a type of automotive braille to determine if he was actually in the lane. The Corvette driver either notice the sloppiness or the look of shear terror on the face of the P-car's passenger (that being my face) because he backed off and moved over to let us by. I mouthed thank you to him as we passed for I was certain Jay Sr. would follow suit. Actually, it wasn't until he decided that he really needed to consume the tablet in his shirt pocket and that it would be difficult to do at triple digit speeds so he backed out of it. A near death experience if ever there was one.
I've polited a race bike to 180+ on a public but deserted road and I know how irresponsible that was. I've done it many times but less and less as time goes by. I've sky dived, shot guns and made love to fast women. No death-bed full of regrets for me... I guess that's what was going through Jay Sr.'s mind, too.
Names have been changed to protect the innocent.
Don't have a pic, but I've redlined 6th several (15-20) times in my MY99 996. It is supercharged, so it gets there quickly enough. Redline is set to 6800 rpm. Digitally indicated 183 MPH (GPS shows my speedo is 5 mph fast across the range, so I guess I was only going 178 MPH). I understand the risks and I do see others' point in calling my actions "ill-advised;" however, my suspension is heavily modified, my aero package is effective, I do have significant track time and high-speed training, we have at least two 12 mile stretches of concrete barrier divided 4 lane concrete highway here in Arkansas on which to play, and I do not do so with other traffic present, so it is just my *** and my car on the line (heck, I don't even have a wife or kids). Flame if you will, I do not mind (else I would not have posted).
I do very much doubt the 203 mph unless the transmission gearing had been changed or the rev limiter moved on that car, as there is simply no way my MY99 will go any faster with its stock 6th gear and rev limiter at 6800 rpm.
OK,
So I was out on a Wyoming Interstate on my own, and I could see about 3 miles ahead, and I planted my right foot. I saw just under 170 MPH on the speedo before I backed off. There was at least a bit more left in the car, but I couldn't take it any more. I sure hope that my rear wing deployed! For sure that was the fastest I've ever gone on land. The previous record was on my 1993 CBR 900RR at a mere 145 MPH. Those were the days!
155MPH in an unmodified '02 996 C2, front felt very unstable. After installing front lip spoiler very easy reached to 165 MPH, felt very stable like it could go higher, but didn't try it.
250 kph (on sat nav) in a lightly mofified 1990 964 -- and it was slowly winding out but was getting a little "floaty" in the front.
Before that (78 years ago) 200 kph (indicated) for one hour non stop in the Northern Territory in a 1976 911 -- very much modified -- and nearly out of fuel at the end of it -- they did not have a speed limit then -- sadly now they have "throttled" us.
