How many of you know what the oil pressure in an ls1 is ?
6psi at 1000 rpm 18 psi at 2000 and 24 at 4000 hot.Your engine requires a certain rate of flow that the engineers at the big 3 have figured out.Most Winston cup cars at 800 HP only have 45 to 50 psi of oil pressure.If you control the internal oil leaks in an engine you do not need that high volume or pressure pump.A small block Chevy with .0025 in the mains an .002 at the rods will need nothing more than a stock pump blue printed.
