Went on the highway today, outside temp was around 85-90*F. I did some normal speed limit crusing and the coolant temps were at 188*F, 8* above what the normal stock rad temps usually are. Oil temps were normal.
I then did a couple boosted runs, +16psi 3rd to 4th gear pulls and temps didnt change much at all, maybe +/- a few degrees.
I did see again a 200*F coolant temp when I was driving in a little traffic but the oil temps were normal.
Side note, the stock coolant temp gauge does not register the changes in coolant temps after it reaches a certain temp, i.e. the needle doesnt move when its 170*F or 200*F.
Im not worried onr bit running this rad. Like I said before its much better than bursting a stock plastic endtank. Ill report back if I observe anything odd that happens.
