Acceleration Detectors

[CSH-HQ]

For back to back testing they are at least fair.
Depends alot on car, and initial "launch".

I made my own time to distance timer.
Rewired a stop watch, and then the timer starts after two revolutions of the 
rear tires, and stops 100 revolutions later.  So it's about 600', plenty of 
time, for hook-up (checking for bog), and some decent MPH (mixture under 
load).  I used stuff out of radio shack, and Forrest Mimms book.  No I don't 
have a diagram, it was a real kludge, but 8 years later still works.
