G-Forces Felt??
I have a strange question for everyone. What are the g-forces felt during a Z06 launch? Standard Z06 will do. So using the Spec sheet 4.00 0-60Mph.
Could anyone provide the equation for this or know of a online calculator to figure this out?

So I figure, The Superman: Escape ride in Six Flags does 0-100mph in 7s. The g-forces felt during this ride is 4.5g. Our car according to Wiki go to 100 in 9.2 second so maybe around 2-3g's?
I know I am a nerd for asking but.... It is late and I am bored. LOL

V= U + at,
where:
V = final velocity = 60 mph (would need to change to feet per second to convert to g's later)
U = initial velocity = 0 in this case
a = acceleration
t = time = 4s
So, a = (V- U)/t
Therefore, a = (60mph*5280ft/m*1h/3600s - 0) / 4s = 22 ft/s^2
Since you're looking for a "G" value, we'll divide that value by 32 ft/s^2 (equal to 1x g), a = 22 ft/s^s / 32 ft/s^2 = .688g's
I think the constant acceleration assumption is "decent" considering a stock Z06 HP curve is relatively linear.
It's been a while since I've done any physics calcs. So, if anyone see's an issue with what I've posted, please let me know.

My Kenwood head unit has a G-meter built into it. Don't know how accurate it is, but on my relatively stock Z, the highest I have seen under acceleration is about .7

I have instrumented the car with real accelerometers and you will consistently see low to mid .6's in first gear. Numbers like .65 g are about it. That is WOT at the torque peak in first gear, hooked up and going straight. That is for a totally stock car with road racing tires on it. If you see more than that you are just seeing the effect of the flywheel when you are dropping the clutch.... That is, you can average .68 for four seconds, but you are doing better because the rpm's are up and you are using the energy from the flywheel to help you accelerate. Steady state numbers are a bit lower
