does one really to mod his car to go past 140? most will do it once to test the limits or whatever, been there down that, though it was not smart.
acceleration is one thinig but top speed!

 

Try the same run with a GPS on board. The GPS speed will be more accurate than your speedometer. If you don't have a GPS borrow one from a friend and just scare the $h1t out of him in exchange!

 

Formulagigi. You definitely have a point there. I would love to be able to be reach 155 mph whenever I'm on the highway. I guess since my first defeat on the highway (if you read my A6 vs Mystery Audi Coupe), I'm kinda head bent on trying to get faster. Accelaration is definitely another thing I have to look into. I received some great tips on launching but I haven't mastered that yet.
