Not Ranked
Okay, I'm drawing on years and years of memory here, but:
When I was in high school I briefly drove a '53 baby window Volkswagen Beetle (Hey, now! That was pretty cool back then!) Anyhow, with the high performance engine I had a remote oil cooler, and I HAD to run a high volume oil pump with the extra lines or risk blowing up the engine.
Okay, let's say Mike P.'s engine has a standard volume oil pump to begin with, and then he adds a remote filter. Should he also upgrade the oil pump to a high volume pump?
I've received many answers to this question, the most authoritative was to not use a high volume pump, but use a "precision" oil pump with standard volume. Melling makes a precision oil pump.
What say ye?
First, when adding a remote oil filter or cooler, is a high volume or precision oil pump upgrade necessary?
Second, which is best: High Volume oil pump; or, standard volume precision oil pump.
Incidentally, for my current 331 build I've purchased a precision oil pump. I do have a vague sense of uncertainty in that Keith Craft, my shortblock and heads source, uses a high volume pump...
