This is off a basic OBD and the temp on the dash (oil generally from what I understand) runs halfway between the first tick and the 210F mark. So, given that I’ve replaced everything I’m aware can be replaced beyond the radiator and hoses, which all seem fine, I’m wondering what operating coolant/water temp should be. On the track I’m running no more than 180-190 coolant temp and 270 oil temp per the dash. Thanks for assist on this trouble shoot.

During normal operation its around 85C iirc. Yes the dash gauge is oil temp, not to be confused with coolant. Sounds like you have 75C ish there(?), which is not normal once the car is warmed up.
