I only use my 2.1 ERST in the summer.. under normal driving the car keeps perfect temp.. BUT once it has afew good thrashes it does get very hot.. My intercooler pretty much blocks the rad and im sure this aint helping things
Could I run it will no stat to try keep temps down???
Removing the stat will not reduce the "operating temp"
All it will do is increase the time it takes for the engine to reach operating temp, theroetically increasing engine wear.
Have you looked into fitting an oil cooler?
