The Lingenfelter Performance Engineering (LPE) high volume GM Gen III & IV V8 oil pump is recommended for use in applications that will require increased pump flow to achieve the desired oil pressure. Engines with piston oil cooling jets, radiused crank bearings, aftermarket lifters or increased build clearances may require a higher volume pump to achieve the same oil pressure, especially at low engine speeds and higher oil temperatures when the pressure relief valve (PRV) is not in control of oil pressure.
