I don’t think you’ll see any of the CMC cars hit 150 at Daytona. It’s not nec a gearing problem but an aero problem. Which ever car is the most streamline in the air is going to reach optimal TopSpeed regardless of gear assuming you’re not hitting the rev limit ha ha. Usually in Daytona they make you go through a small cut off halfway down the straight away to limit the top speed of the cars in the race but I don’t know how NASA will run it.
