The stock turbo 335's wont run as strong as they do at sea level at this elevation, the same as the Willow event the only way for Hotrod to get some good clean data is to throw his 4 mods in and bring the car.
I mean what perfect time to do it open event 6 more modded 335's same conditions same strip everything the same. Really to be there as a spectator I can already tell you that you won't be able to refrain from your deductive reasoning of comparing your car to those at 1600 plus elevation which would be a biased comparison. Even comparing your run with Xtyper at sea level to his run at this event with other cars would be biased. But I'm sure you will do what you will do.
I think the best thing to do is come with the car the N20 is obviously not here yet to buy. I think this would be the first unbiased runs that you are able to run with multiple tuned cars.
You should bring the car
