Pretty cool car acceleration calculator

I stumbled across this car acceleration calculator the other day and I found it to be a pretty fascinating way to test how different variables will affect the acceleration of my car. Has inputs for pretty much all the important factors: weight, gear ratios, shift speeds, aero factors and most importantly it allows you to plot the exact rear wheel torque curve of your vehicle (just take your wheel dyno figures and plug them in by clicking and dragging the bubbles to the correct figures using say 200rpm increments).

I dont have access to a Vbox, nor do I really want to try testing say 60-120mph acceleration around where I live, so this is a great way to generate some theoretical numbers. I would think that if you input the data correctly the model comes pretty darn close because 60-120mph takes driver skill and launch technique out of the equation .....
