I know at high speeds the speedometer can by slighty un-reliable, but i was driving my car the other night (on a safe road- private road with no other cars on it-that is closed to the public )-((that's for the cops)) anyways so i was driving and i got the speedometer pinned at 160mph, but the car is suppose to be limited to 155mph??

(friend took the picture-sorry that its blurry (damn camera phone))

Speedos can be anything up to 10% in error. That's only 3%, and looking at your picture it's more like 159mph. But why is the discrepancy so important?
Things like tyre pressure/temperature and wear can also have an effect. An over inflated new tyre will have a larger rolling diameter than an under inflated worn one.

Not really that important, I'm just curious, the picture was taken a little early but I did have it pinned at 160.....let say I was going 165 would the needle push past 160 or just stop at 160

You would not be doing 165. The car does not do 165 in road spec. So it's academic.

A standard German spec SL500 clocks out at 250 klicks per hour (155 mph) - the speedo will give you something just shy of 160 mph. What you took a picture of doesn't look off to me, but my hat still goes off for trying in a country where this could mean going to the slammer ;-)
