Will my car go as fast as the speedometer says it can can? I have a 1999 Jag XJ8 and the speedometer goes to 170 pmh. Can this car really go even close to that?

I had a POS Plymouth Colt Vista back in '95. It started buzzing like hell when it hit 80, but the speedo went to 140.
Only way that thing was going to see 140 was if you dropped it out of a cargo plane. |

I drive an 89 F150, speedometer goes to 85 and I know for fact it will do at least 87 because that's what the DPS troopers radar said.

I wanted to test this theory out, but when I put my speedometer on the road it just sat there and didn't move an inch.
So I think my car goes a lot faster then the speedometer does even with a big hole in the dash! |

No way. For some reason there are a lot of non-gearheads that believe that whatever the maximum is on the speedo, is what their vehicle will do.

My Civic's speedo goes to 150. That might be a tad... optimisitic.
I owned a Porsche 911 with a speedo that only went to 85. |
|
The car will go at the same speed as the speedometer unless you physically remove the speedometer from the vehicle.

Since the speedometer is physically attached to the car, it will go exactly as fast as the car does, no more, no less.

My BMW goes to 155. Both on the speedo and the actual speed.
Verified by GPS. |

A pet peeve of mine is unrealistic speedometers in non performance vehicles.
I'm not for .gov regulation on this matter (like it was with the 85 max), so what I'd like to see is a variable display. Since it's now 100% computer controlled anyway, why have multiple background options. 0-85, 0-110, 0-160, whatever... If there must be one by law, why not continually tighten the gradient as you go faster to allow for fine readings at the low end. The numbers and needle travel would modify accordingly. MPH/KPH could be handled in the same fashion, no double scales. My hooptie GMC has an 85 max, and the speedometer covers 180 degrees. It's a pleasure to deal with in the city or school zones. If I was to take it over 85, I'd be more worried about it turning into a bowling ball than I would about 'knowing' my speed. |

Of course it will. It's mounted in the vehicle, therefore they will always go the same speed.

My Jeep Cherokee Speedometer only went to 85. I had the needle past that a few times when I was young and stupid.

I knew before I posted the question this way I would get ridiculed. As I said earlier,...I'm in a dangerous environment and my concentration is not fully with ARFcom. |

A "Gentleman's Agreement" among the manufacturers to voluntarily limit top speeds so the government doesn't step in and mandate something ridiculous. |
|
The question is where does your car cut out at. I had my 4x4 over 100 by the speedometer. It was a bounce ride and felt like at any minute it would end badly so I slowed down. So I don't know where mine cuts out at but a high center of gravity on it won't let me try it any faster than that.

Does anyone remember the "good old days" of speedometers that only went to 85?
I know for a fact that a 1986 IROC will go over 85 indicated. I also know that a 198? Oldsmobile Delta 88 sedan will go over 85 indicated. I further know 1987 Cadillac Eldorado will go over 85 indicated, and the digital speedomotor begins to blink. Interestingly enough, I also know that a 1984 Cadillac Fleetwood sedan will also go over 85 indicated. I'm also pretty sure that GMC and Chevy Suburbans of that era (we had a few) will also exceed 85 indicated. Noticing a theme, here? |

My '88 Corvette had the bar graph analog equivalent that stopped at 85, plus a digital readout that went as high as the car was capable of going. |

Quoted: Newer cars, no. Restrictor plates... Restrictor plates? You for real? |

The first car I drove was a Ford Probe 4-cyl, 1986 I think.... The speedo went to 115. If you got it up to 105 or so, the transmission light would go on.
(I almost never jacked around in cars like that really, but I did do a straight-line speed test once) ~ |
|
Don't be a pussy, got find out for yourself.
My 95 Mustang GT would top out at about 125 on a 150 speedo My 96 Cobra with a little bit of work would hit the 160 on a 160 speedo. |
|
My P71 has a speedometer that goes to 140, but IIRC it also has a govenor that limits it to 130 or 135.
As long as I own it it will never see triple digit speeds, FWIW. |

GM must have thought it was uncivilized to speed in a Caddie, b/c it did just blink 85. We had a '90ish 'Vette that did what you describe. Good times... |

US gov limited to 155MPH There is no US government rule or regulation that limits top speeds. The 155 limit on some vehicles is the result of a gentlemen's agreement in Europe to preclude governments there mandating a limit. |

my 2007 1500 silverado got up to 115 on 460 a couple years ago!!!
all of the fuzz was at the Hokie game so I wanted to see how fast I could go... |
|
I've never gone over 100 in my Jag. I can't imagine the problems it would cause me if I got caught trying to do 170. I work for the Sheriffs Office.
Had my Cuda buried at 125 and climbing when I was 18 Bad idea when the windows are down and the carpet was pulled for replacement. It was like a wicked desert storm in there. |

All cars unless you mod it to not have one have a govenor. Like my lexus is300 stock goes 142 in my turbo IS i have been 160 and it will go higher.

Go out on the interstate and try it
Then check back with us, post pics too |

My 4cyl Accord has 160 on the speedo...riiiiiight. It's smooth sailing at 100mph though

My wife's Odyssey has 140 on the speedo.
It's optimistic, of course, but it does make me feel as though my attempt to reach 140 would be accurately documented at the point of failure. |

The first vehicle I ever bought was a 52 CJ3A with a Buick V6 and a Warn overdrive. The not-stock speedo went to 160! I don't know how fast it would go but 65 was scarey enough for me!
