really not sure where to post this, if it needs to be moved thats fine

2006 wrx wagon. vf39, 05 STI drivetrain swap.... plus much more of course

having major overheating issues on the track. Only able to run like 1-1.5 laps before the needle just soars to the red. I have upgraded to the mishimoto radiator and am running my heater already. thermostat has been drilled out, both caps are 1.3bar. I have a splitter/undertray on that extends back behind the oil pan, and I have the greddy air panel diffuser thing on the top that connects the bumper to the radiator. Running probably 1/4 dexcool, 3/4 water/water wetter. fans work as well. removed the grilles and took off my hella supertones to try and get even more air in.

really not sure what could be wrong still. Only runs hot on the track, not on the street. The A/C condensor is pretty ****ed up on the bottom half, but because i have air being forced through from the top and bottom, i dont see how it could be the problem still. Also because I really opened up the top half to air (which looks fine) it doesnt make sense.

what soultions should I be looking at here? any help is appreciated
