No, I'm working on a program to predict 1/4 mi. ET and trap speed and 0-60
acceleration times and I need the data. Taylors book is an excellent source
of this type of info but no aero drag type stuff.
This program will be used to help choose the ALP2300 transmission and rear end
ratios and my Tiger rear end ratio. It will also help select shift points for
best performance, estimate top speeds, let you see what different
engine/gearing combos would do in the Alpine/Tiger body, etc.
It has a long way to go yet but I'll show you what I got on Sunday. Right now
it plots time to distance/speed from some basic chassis/engine inputs (like
torque curve, gear ratios, etc.) and includes corrections for drag but not yet
for powertrain efficieny, shift times, tire spin at launch. I don't think the
accuracy will ever be much better than about 5% absolute but it should give
good differential information for those what if scenarios.
Any thing you could pass along would be much appreciated, thanks!
