While on Dave Layers dyno several years ago we broke off the oil pump pickup. Had around 3 psi for the entire pull as it went unnoticed. Yes Dave was red faced about it. I always believed in Amsoil after that. As the bearings looked absolutely brand new afterwards. There was 4 to 5 difference in the previous pull and the one without the pump pulling against the engine .. So if your cutting it from 80 to 50'ish I don't know, but less that that ....,,,,

A very respected engine builder was making Dyno pulls on a customers 305 stocker motor. At the end of the day they drained all the oil out and made a pull. It was 8 HP better. The names are intentionally withheld to protect the innocent….
