Where do these NPK street outlaw guys get all their money

i believe merchandising money which is wholly the teams, is the real bread and butter.

add in the sponsorship deals that could be parts, machine work, clothing as well as the TV money, and possibly contingency money.

as mentioned a lot of them have successful businesses and with that they buy the haulers and cars, put their names on them and now they're a write off thru the business.

i don't know if any of them have any action in the production of the series: producer, created by, technical consultants but if they do, that's real big money.
