I upgraded to a t66 recently and was wondering what the maximum I could clock it to? Cant seem to find any solid answers online, I currently have it at about a 25 degree angle

Garrett says +/- 15° maximum allowed angle of CHRA oil drain.

That’s a great link. When I went looking for info on a Turbonetics of yesteryear, there was nothing.

well that's a bummer just checked and I'm at a 23 degree angle, anyone have any ideas. I've tried a 90 and a straight and both seem to hit the manifold or end or it ends up being past the recommended 15 clock. Currently I have a 90 going out and the turbo is at a angle that allows it to clear the manifold.
