Anybody want to school me on stall speed?

There's an easy way to get the two stall speeds if it's in the car:
For the brake stall - hold the brakes on and push the gas in drive. Where the tach stops is the brake stall speed. That is the lower of the two.
For the flash stall - drive the car in drive to about 30mph. Let it go into 3rd gear. Once it's there, press the gas as far as you can without having it downshift. The rpms the engine reaches and holds for a sec is the flash stall. It will be higher than the brake stall.
