5400 RPM in is what you reached but your speedo only reads somewhere lower. Go out and do 1800RPM in
5th. Record the speed. Say 50MPH. You can simply triple the speed and RPM to get 5400RPM and 150MPH.
This works only if you remain in the same gear and it also works because there is a linear
relationship between speed and RPM in a given gear. This method is FAAAARRRRRRRR more accurate than
the calculators.

i never said weight mattered, but what does matter is the frictional force between the tires and the ground, which will affect how fast you can go. Also, by calculating the speed at a certain RPM, u can not determine another speed by calculating another RPM, because although that relationship is linear, the wind resistance goes up dramatically when you begin to reach higher speeds, as well as all other forces acting on the car trying to slow it down....jsut my thoughts...im no rocket scientist but i am a mechanical engineer
although, if u got the power u got the power aint no wind gonna stop you
