in a circular race, MINT400, UTV WorldChapmionship, Parker 250 and a few others, the team sets up in a pit and stays there the whole race. Easy Peasey for you to try to pay someone to also help pit you BUT you have to remember if you and THEIR team guy are 10 seconds apart and both pull into the same pit and the same time, their guy will get priority and you will sit and wait.
in the point to point races like baja and V2R each team needs multiple vehicles to bunny hop ahead in order to stay ahead of the race car. for example
2 chase trucks minimum needed to chase V2R effectively. start of the race, chase1 truck heads up to pit 3 while chase2 stays back and watches the start of the race and makes sure the car makes it thru the first road crossing. At that time chase1 is pulling into pit 3. when the car runs thru the road crossing chase 2 heads north for pit 7. about the same time the chase2 passes pit 3, the race car is pulling into pit 3. Chase 2 continues north for their pit to get a parking spot and set up and tools and gear out for the race car. Race car leaves pit 3 and chase 1 cleans up their mess, loads up and heads to pit 10. by this time the race car is making great head way and as chase1 crosses thru the first town they need to fuel and grab drinks and more ice (its 115 out there remember) race car is already coming into pit 7 before chase 1 even gets to that point so they scramble to get up towards pit 10 as fast as possible.
This type of bunny-hop goes on for 20 hours. and the problem is, if you are with another group, once their car leaves pit 3 they have a limited window of how long they can wait, so if you are running behind, had a flat and lost a half hour in traffic, those dudes are checking out and cant wait all day on you no matter how much money you are paying them.
There are helpful guys like baja pits and checkers and with enough money you can pit at BFGpits i am sure. folks that you give fuel cans and fuel before the race and spare tires and they carry them to the respective pits with them. does that mean they know how to fix an electrical issue for you? no. can they change a tire? yes. but trying to race a point to point race with another crew as your pit strategy will end up leaving you empty handed at some point. what if you are having a great race, and their team got stuck at pit 9 with a blown front end. they will sit there and fix their car and you wont have anybody bunny-hopping ahead for you.
i think getting to know some teams, coming to a race or two, figuring out how it works and how stressful and hectic it can be will give you a new found respect for the teams and REALLY appreciate how awesome it is to win one of those races. its A LOT of work.
