ok, thanks. how does it work exactly. If I want to start a team, is it like rally? you can buy a car and modify it? do teams change brands often? or are teams factory owned?
Engine wise the same, are they 'normal' engines tuned by a team or more like f1 and specially made and tuned by the manufacturer?
it depends on the team and the deal. as far as factory support goes, it's mostly money and maybe tech sharing with the teams but that's it. the teams are responsible for their own equiptment, but each manu has one or two key teams that they support and all the other teams buy stuff from....
for example with ford roush pretty much builds all the engines with ford support, and yates works on most all the chassis - and the other ford teams buy cars from them. Chevy supports both hendrick and RCR, and then the chevy teams buy from them - stewart/hass, hall of fame racing buy from hendrick, while Ganassi/DEI buy engines from RCR, but build their own chassis.
most of the small 1-2 car teams buy complete cars from the big guys and go from there, but there are some small teams that build their own engines and chassis, not many though. as far as the engines go, everyone does different stuff. they have to use the same block, but apart from that a Hendrick engine is completely different from a RCR engine - even though they are both running chevy blocks.
Toyota is really the only one that does it different, they pretty much sell the engines to the teams, like Red Bull and Waltrip - and then those teams modify it from there, but share their tech back with the factory who sends it to the other teams.
when you listen to the drivers talk, they are contractually obligated to mention which engines their runnning. so JPM for example will say " the power from these RCR engines was good today"
none of the teams are factory owned, it's not normal for teams to change brands often, but everytime a contract is about over, they all look at the other brands and see who's gunna give them the best deal - but manu's do offer extra to keep a team in their stable
