Just another Eddy headed 410 sb mopar...

Air temp was cold, so getting oil and water temps up is more time consuming so I will lower the temp that we test just so we don't go through 20g of fuel!
From 140 to 165 in water temp I've only seen about 5HP but 10° in oil temp can be 10HP! It's not linear though so at higher temps it will start making less power like around 200° oil temp.
It takes quite a bit of time to get the oil hot from a pull, then changing things then another pull so to keep from using alot of fuel we try to test around 160° oil temp.

Yes the damn oil pressure was real high but a high flow racing filter and 5w20 oil will cure that, just didn't have the time to do that so there's a good 5-10Hp in lower oil pressure.
