Fitted my 16row mocal oil cooler with stat on friday, fitted above gearbox, but below brake servo.

And done a Trackday yesterday, and on 18psi boost, and 15-20min's hard sesions (with no easing off) oil temp was 110-115oC at hottest.

Along with water temps of 94+oC, but i removed stat, and didn't change.
So time for coolant mod's.
