Just reading some old posts, and I am wondering what size of track are you running on? How long is your straight, and is the infield technical or smooth flowing?
Our track is 30m * 12m, with a pretty technical infield. I run a considerably different rollout then you do. 78-82mm, with 20 endbell timing (novak 17.5), and 29 dynamic (everything on Max) with the 1S HW. I still feel like i am not in the cars sweet spot yet, the other cars are faster on the in field and the straight!
