I'm assuming that that would be way to low for the track, is their a similar process for the track or just kinda guess or use the 2/3 body-weight formula I saw on here somewhere or set and forget?
I would start at 100psi and go from there. I say this because you can really get away with much lower pressure on the road, and it also has to do with your tire pressure being a large part of what locks your bead onto the rim. On a 333m track, a 30km/h-ish cruise will keep you perpendicular to the bank. You are most likely to be riding much faster, and often, quite a bit slower. Track racing puts a lot more dynamic force onto a tire than road racing does, and it does it more often. You're more likely to roll a tire on the track than on the road. I would start at 100, see if that's too hard, then drop to 90. You will notice handling issues with lower pressures sooner when on a track.
Then again, the lighter you are, the lower pressure you can get away with.
