stock or hv oil pump
Right, PLUS all the AIR in the line still pushing the OIL against the gauge! lol "WHOOPS"
Rusty there is some truth to the small diameter pick ups and HV pumps. There is published testing on it and the style of pump Chrysler uses makes tube diameter all the more critical.
That said, most of the testing I can find was done in the late 1970's and maybe the early 1980's. You and I both know that back then, 20w50 oil was the de facto oil.
Hell, I know guys who clear up to the 1990's who were using a single grade 50!!! And that goo, especially when cold has a devil of a time getting up the pick up.
Of course, I don't care about any 50 grade oil even at temp, as they are still too dam think today.
So, if you are using a 50 grade oil and have it to temp, trying to feed that pump at say 7000 or higher and the pump starts to cavitate.
Today, if you are running a decent 30 grade oil, it's not nearly as hard to feed the pump. But it can still be an issue at engine speeds above 5000.
