Car Nut said:I've "heard" that our speedos can be off as much as 20mph at 150, i.e. you're only doing 130 when the speedo says 150. Also heard that they start getting out of whack like around 90 or so and from there it is moreinaccurate. Maybe 20mph off is a stretch, but 10 to 15 mph off is easily acceptable.
Not saying that anyone didn't go a particular speed, just that I agree that the speedo cannot be trusted at all at high speeeds.
Car & Driver did the 0-150-0 tests and commented on several of the cars about how off the speedos were. None of them were real bad, but a couple cars "appeared" to be going 160, when in reality they were just hitting the 150 mark. Granted, magazines are not usually the optimum place for facts and what not, but it is a fact that when magazines, manufacturers, or anyone else wants to know the "actual" speed of a vehicle in speed tests, you always see a lot of equipment strapped to the car in order to get accurate measurements (or laser guns, etc.).
Sorry so long...........I'm bored at work right now and the fingers won't stop typing........No offense to anyone.
That's all internet heresay and speculation. Not flaming you at all though, just don't want to see the internet go far astray. In most cases your car is not going t obe 20mph off on the spedo. If it says you are doing 150mph you are probably real close. Now as to doing 150mph..that is ir-responsible especially with a passenger in the car who may or may not have a family or kids or even a dog that is home relying on him/her. Not to say no one has done it but it better be far and few times in between. Especially on a public rd
. everyone that does illegal things knows its "wrong", but no matter how much anyone says, it will not change anything. same goes for drugs, underage drinking, etc. its pointless to argue anymore.
