How Fast Is Fast To You?

true that.

NO, don't think my math is off. I used the wrong numbers. By going 186 MPH in the opposite direction of the Earth's rotation ( to an observer in space), your'e still going 700-186=514 MPH in the same direction, which agrees with your statement. To be going backward to our observer you need to be going 700+186=886 MPH in the opposite direction of the Earth's rotation.

In addition, your statement about speed is correct. SPEED is only a magnitude, and VELOCITY has magnitude and direction. So if you use the word "velocity" while bragging about "speed" you need to include the "direction" (probably forward) to be correct. Ask any high-school physics student.

Airplanes- I've litterally seen one fly off the ground with NO groundspeed. There was a sudden windstorm with gusts to 80 MPH. I can even attest to your other example by a friend of mine who hovered over a runway in an airplane (60 kt crosswind).

thx

How fast is fast? is a relative question, but if your z can go 170mph (3.0l to 2.0l) you would set the land speed record at Bonneille Salt Flats. The record is 169, I would say that is fast.

all in good time and you will see my name as the new record holder!

That doesn't seem too unattainable? I once looked at buying a 240Z that did the old "diesel crank" trick to turn his 2.4litre into a 3.1litre - it was speed trialled (with documentation - which alone impressed me!) at 163mph. I'm sure if he'd lightened the car by taking out passenger seat and spare wheel, etc it might have made 170mph?

Vicky, when he said the targa top was out, he meant in the Ferrari, not in the airplane. Read it again

I know, I was just funnin' the guy. :laugh:

Where I work we have an old peice of $hit dump truck bought as surplus from the military. In that truck 35 MPH is fast to me. The thing starts to shake and the steering gets very loose and the front wheels start to shake so bad you can not even steer the truck.

nope,

weight is only i tiny factor in top speed. aerodynamic drag would be the biggest thing to work on to go any faster.
