Chi, I has the front end about 18" off the ground.
Boogie, this was happening not boosting at all. None. From a cold start up all the way up to that temp. And I'm only running 9psi as well, if that matters. It never got hot when in boost. Once it got hot and I pulled over and cooled off, I could drive it the rest of the 15 miles, with WOT pulls, and not get over 210*. It was like the tstat was sticking a little bit at first but once it opened and I slowed down, the cooling system caught up and everything was fine after that. Very odd.
I do have a block tester with me at work I wanna try just to see.

I think I'm all good now. I left work, warmed up to 198 and dropped down to 187 and stayed around 190 all the way home while driving like an ***. Raced a 240 from a roll and smoked him, and then got my *** handed to me by a SV1000 from a light.
Side note, does anyone know why my charge light comes on when I hit the rev limiter? I've tried adjusting the settings in the alternator options to make it less sensitive, but haven't been able to figure out how to make it stop doin that.

Since you say it gets hot quickly and then suddenly drops, you should check that the little bleed nipple in the thermostat housing is open. It tends to clog on older cars and causes this exact symptom. Basically, when Mazda moved the thermostat to the "front," they created a dead zone in the coolant that takes a long time to warmup, which means the t'stat will open really late. That nipple is there to eliminate the dead zone, but needs to be free of crud.
