I pulled my oil cooler off as it was not keeping pressure after the car sat off for a while. To be honest I dont think there is a need for them, ran plenty of track and drag days in mine without one with a Defi oil temp gauge and never seen any temps of concern.
Is it a remote filter set up on it? The height the filter is can play a part in all this apperently, not something I messed with at the time to see if it made any difference but read up on it.
