[T3] Thoughts on overheating

Originally I used the ISP manifold with both the pressure and temp senders in it. However, the temp readings were never useful. They took too long to move at all, then shot up and stayed warm without changing even as I changed the load on the motor. I concluded there was not enough flow past the sensor to register properly.
That’s when I read about the inline fitting for the filter lines. That made it responsive, but the inboard location has spoiled the high temp readings. I’ll move it outboard right at the filter housing, and I bet I find that solves the issue.
The filter was reading about the same temp as the sump, so it would be a good reading of pre-cooler temps. This would be higher than what the bearings actually see, but it would be (1) responsive and (2) consistent, which is all I really want from the gauge. That way I know when it is warmed up, and I will know when I get an “out of family” reading that indicated a change to be investigated.
I’m in no hurry on this now, believing it is not overheating… a few weeks at least, but when I move it, I’ll report my results.
Thanks for the ideas.
