Oil temp once again

[Ben]

Probably because with your Tiny turbo at 80mph you are boosting 10-20 psi. Putting more load on everything.

Only the turbo that's working harder, not everything else. Air temps will be hotter and so will the oil passing through the turbo but nothing which should raise the temp above the usual. Don't know what the usual oil temp is but I'd imagine its not too far off the coolant temp.
