The weight you must be equal to or greater than , when you go across the scales is called the "minimum weight" . It is usually equal the min Class weight break times your factored horsepower , plus 170 . The exception to this is then you try to change classes up or down , you can only adjust the weight by 250 lbs. from your natural weight break , which is found in the NHRA Classification Guide .
