I’m sure for the guys that run a lot of 1/8 mile, they might have a good handle on what’s a decent slip value for 660’.

Most combos will have way way more slip at 660’ compared to the full 1320’.

Myself, I have no useful data for converter slip at the 660’.
I race 1/4 more than I do 1/8 and will setup the car for 1/4.
