Are you having Challengerfest this year? If so, maybe have a Demon170 shootout.
I'm not sure. The track has gotten a little interesting to work with since Dallas passed. I looked at an alternative and was quoted a ridiculous daily rental rate. Think 5 digits!
For the Demon to run "well" it's also gonna take good radial prep, which is rare. I think a lot forget that variable. I'm expecting to have to pull a lot of power at Beech Bend.
My educated opinion is that if a team of engineers is told by their boss "I wanna sub 9 second pass" that team is gonna do whatever it takes to get there and have access to all manner of tools to do it. Woulda be nothing for them to play with the tune a bit, etc, I mean they have 100% access which not even aftermarket gets us. Make it believable enough and let folks chase it adding to the legend of the car, great marketing.
It's what I'd do.
A lot of people actually believed the demo car ran 8.91 at 151 at the Vegas reveal and didn't think about that just being programmed in to the timing boards for marketing.
