Hi Neil, I dont remember criticising, but maybe I did. Anyways your setup
works, thats all that matters.
Keep us updated with the turbo install. Tis fun to tinker, but more so to
fly.

Pulled my oil filter & adapter plate off this arvo, realised the temp
sensor that is reading high is not completely in the oil flow, just the
very tip is, with rest of sensor in contact with adapter plate, so maybe
I=E2=80=99m sensing the rear iron temp rather than oil temp. would explain =
a lot,
and be a bugger, as I may not have had oil cooling issues at all for all
this time.
