Does that mean to run F at 11.0 times 299 for HP then add 170 pounds (- 80 lbs me)to get car weight? Any help will be appreciated!

What you posted looks like you have a handle on it. It's pretty simple. It's your NHRA HP factor multiplied by the weight break for the class. So, yes, 11x299+170. And you simply subtract the amount you weigh over 170 from the weight of the car.


Good luck and have fun!
