So I experimented the weekend a bit with some of the advice I got from some of you... To solve my overheating problem...
I've seen some sills on the net to plug the holes between the FMIC and the radiator, this weekend I built my own temporary ones from cardboard to test if it really works... needless to say... It does!
it must have helped, during the weekends town driving and my drift practice my temperatures where quite stable... never really increased more than 3/4 of the gauge...
