Your Top Speed

buried speedo on my sold 01' hayabusa more than a few times...
same thing on my sold 01' gsxr 1000 (painted it spicy and sold it the same day)
165 in my sold 91' tt300z,a few times
150 in my sold 89' saleen, several occasions
142 or so in my sold 89' vette
130 something, until my msp shut down, a few times
I know, alot of cars, I am older and not much has changed...still like going fast, but I keep the speed anyway, haha
theres more but you get the idea...

I agree with the other person that commented on the verification with some sort of timing equipment.
I guess the percent error in the speedos is fairly high once you get up to the 120+ speeds. I can't imagine a '01 Camaro SS or even a '94 Camaro getting up to 165. Given that I think all the auto rags I read said they topped out at ~ 150. Granted their equipment is more accurate than the speedometer in these cars. Just goes to show that people will believe whatever their speedo tells 'em.

Ah well... that's life.

My WRX 155mph. Me driving, By speedometer, it only goes to 140 but was between the M and P in MPH which looks to be about 155. Modded Audi S4 beside me said I was pulling away and he was doing 150.
Friends 95 M3 160,friend driving, by speedometer.
02 Boxter 150 me driving, by speedomer
My old MP3 120mph

Fastest I've ever been is 155 in my friends Mercedes E320. That's a stupid fast little car for a 3.2 v6.
Actually, I take that back. That's the fastest I've ever driven. The fastest I've ever been is in my friends roomates 350Z, about 167

Well you have a point, but according to those same magazines, the P5 tops out at 112.
My stock P5 has a Georgia State Highway Patrol rated top speed of 122. And that's after I had let off.
Not to push the point further, but this is an interesting excerpt from the third link I posted:
Systematic corrections that are not eliminated during calibration or applied as a correction, will contribute with opposite sign to the results of speed measurement by a police pursuit vehicle. For example, consider a police car tested at 100 km/h with a reported error with new tyres of +1.5 km/h (that is, the true speed is 1.5 km/h lower than the indicated speed) and which eventually has tyres at half wear equating to 1km/h. A motorists vehicle is then perceived to be travelling 2.5 km/h faster than actual. If the motorist has a speedometer error of -1.5 km/h and is travelling at an indicated speed of 100 km/h we can see that it has been measured to exceed the speed by 4 km/h, enough to be considered a breach of traffic rules. These errors created by, (a) tyre wear, (b) not applying calibration corrections, and/or (c) the roller-to-road anomaly, are critical to the overall picture, since the accumulative affect can be as much as 4 km/h.
To calculate the uncertainty associated with a drivers knowledge of the true speed of his or her vehicle, a review of the components of uncertainty arising from interpretation of speedometer indication, vehicle load, engine power management and tyre behaviour was undertaken by the author.
The drivers ability to accurately determine the vehicle speed using an ordinary speedometer is affected by:
*The intrinsic accuracy of the instrument (the residual systematic error after calibration).
*Parallax error.
*Size of minor graduations (normally 5 or 10 km/h).
*Readability (usually one fifth of one minor graduation).
Based on these factors uncertainty (expressed as 95% confidence intervals) for a speedometer read to 2 km/h was as follows:
60 km/h is 8 km/h
80 km/h is 10 km/h
110 km/h is 13 km/h.
What's my point? You guys aren't going as fast as you think you are, your speedo may indicate, or the cop tells you. In most instances you will be going slower. Keep in mind that the article above doesn't directly address issues with different sized rims/tires, but it does discuss speedometer calibration.
