Testing HP without dyno


#1

I want to know if it is possible to measure my horsepower without using a Dyno. I have a 91 Honda accord 2.2L sedan. I don’t know if it helps but I am capable of weighing the car accurately and measuring the time accurately from 0-60. Any way to make a formula to measure the HP from these measurements or any other way without spending $$$. we all know how tight cash can be these days.
