For the next week, V8 Supercar drivers Todd and Rick Kelly want to be known as America's Team.

Just down the road from the NFL side which has made that moniker their own, the Dallas Cowboys, the Kellys head to the ground-breaking V8 race in Austin, Texas feeling like it's a home event.

Both their major backers - Jack Daniel's and Nissan - are based nearby.

The road version of the Nissan Altima car they drive is built in Tennessee - also the home base for their whiskey-maker sponsor.

The Kellys arrived in the United States early to catch up with their sponsors, tour their facilities, and spread the word for the three-day V8 Supercars event which starts on Saturday (Australian time) at the Circuit of the Americas.

"It certainly does feel a little bit like our home track," Rick Kelly told AAP.

"We've been with Jack Daniel's for so long - since the birth of our own race team. This is their home and we've been here before, and the Altima's made here too.

"We really feel we need to get a great result at this track in particular, because this is where the companies that are very loyal to us are from."

Jack Daniel's Racing's switch to Nissan this year has not been without its difficulties.

The Kellys had to build four brand new cars while racing for Holden last year and deal with the category changes through the new Car of the Future program - without the reference point existing teams had through keeping their associations with Holden and Ford.

Todd, who as both driver and team owner also carries much of the race team's technical load off-track, admitted there were times he didn't think their ambitious project would make the grid for the start of the V8 season.

Four rounds in and with a couple of top 10 finishes to buoy them, Todd doesn't believe a race win by the end of the year is out of the question.

"People forget the magnitude of what we've had to do - we're certainly punching above our weight," he said.

"We've had a few teething problems but, considering the size of the job we've had to do - build an engine from scratch - I think the results have been quite good.

"(Podiums and wins) can't be expected until we get the engine program a little bit further on, but the cars and our engineering group are fantastic."

He admits Jack Daniel's - which produces all 11 million cases of the whiskey made annually from one plant in a rural town of 400 people and one traffic light - provides inspiration for what his built-from-scratch team is trying to achieve.

So too does the incentive of American representatives from both backers at the Circuit of the Americas for Monday morning's (AEST) race having their first live glimpse of what their money is buying.

"No pressure on the weekend," joked Todd.

"We're going to have a lot of extra sets of eyes watching us than normal."
