On the way home from work, I took note of some peak holds which I haven't cleared since the beginning of this year. We've also had our share of 100+ weather. BUT ... I've never tracked my car so I've never hit limp mode.
EGT = 1453 at the manifold
Oil T = 233
Coolant T = 222
For reference at idle, the EGT goes down to 700-750.
So yea, the turbos will not add much more heat to the oil but under boost, the higher EGT WILL. If I tracked my car, I'd add an oil cooler.
