Auto Math Formulas

Hi, guys!

I'm sure most of you have one of your own (or similar), but for those of you who don't, or would like to have the formulas in a file, here they are.

I'm talking about the Auto Math Handbook from HP Books by John Lawlor, which contains the following formulas:

- DISPLACEMENT, STROKE & BORE
- COMPRESSION RATIO
- PISTON SPEED
- BRAKE HORSEPOWER & TORQUE
- INDICATED HORSWEPOWER & TORQUE
- AIR CAPACITY & VOLUMETRIC EFFICIENCY
- WEIGHT DISTRIBUTION
- CENTER OF GRAVITY
- g FORCE & WEIGHT TRANSFER
- SHIFT POINTS
- QUARTER - MILE ET & MPH
- INSTRUMENT ERROR
- MPH, RPM, GEARS & TIRES
- TIRE SIZES & THEIR EFFECTS
- AVERAGE MPH & MPG
- BLOOD ALCOHOL CONCENTRATION

One day I uploaded all the formulas into an Excel file, in which you need only to tab the input data and it will calculate the result. I find it convenient, even though it's just an approximation, it's fun to play with too!
