when speedo says 140.....

[Daniel50]

i have 3.73's installed. i had 2.73's. didnt correct the speedo yet. just wondering when my speedo says 140 how fast am i really going? this is a hypothetical question

 

[Maryland Stang]

102 mph. Nope, you weren't going nearly as fast as you thought you were.

i will second the 100mph's

Simple ratios Daniel - (2.73/3.73)X140=102

It looks cool to passengers...but you are only going 102MPH

...and, you get REALLY good gas mileage now...
