Testing vehicle Speed

[spike52]

Every vehicles' speedo will be off.

A couple of MPH or so, not the 20+MPH that he was describing. That is definitely not normal.

If you have a set of tires, other than what the original specs called for, it will affect the speedo. Look in your door jam and see what tires were original equipment. The best thing that I have found to check your speedo, is to run a measured mile at 60 mph and then calculate the actual. Of course, I am sure that the dealers would check it out, and give you a nice big bill!

Sounds like that pregnet roller skate is a brown paper bag handing out hall passes with his kodaik (decode that and you should a cookie)

Just a foot note for you, Divide 1 mile/x seconds * 3600 secs/hr = calculated miles per hour.

Set the cruise, and there you go. Do this 4-5 times and you'll have a fairly accurate reading.

Just an update it was 10-15 off and I think it was the rebuilt trans. It was prof. done so it shouldn't of done this but needless to say I'm not going to that repair shop again.

Do you have the original size tires on it or have they been changed to another size?

Since this thread was started I have finally fixed the problem, quit driving it. No seriously I had to take the tailhousing off and put in the speedo drive gear. Previous owner had tranny rebuilt and the gear was wrong. Problem fixed. Thanks
