How is a top fuel car weighed at the scales?

[TF CREW]

The scale question i have for today, is how do you weigh a FC for example that shed the body in the lights? Many times, the FC that blows the body sky high, and 16 qts of oil, and etc and etc, will get the win light. How do they weigh that???? They have no idea what it weighed before it turned into confetti. Densham @ Sears Point for example. (NOT saying he is/was/ever has been light), but how do you know he wasn't 30#s light?

Just a question that has been bouncing around my head for a few years, and i've never found an appropriate answer.

they are usually waived.... for multiable reasons

And it's not like they haven't been weighed all weekend. I think they just give them the benefit of the doubt.

cars are weighed first Qualifing round and then only again if position is improved on. On race day only if they advance rounds.

Precisely my point. They've been weighed before that weekend.

They make scales that go under each wheel ! Remember the pro stocks have to carry X amount of weight on the rear and front.
Weighing NHRA is an exact science !
In fact you can get penalized if your wrist pin keepers are off a couple grams the wrong way ! Ask Jim Yates !

The dot weighs a truck and trailer by weighing the steering tires and then the drive tires and then the trailer tires and adding the weights together for a gross weight. That is the same way a Top fuel car is done on a short scale except they only have 2 numbers to add up.
