Small Block LS Engine Dyno Testing Part II - Big Power, Small Budget
|
Rather than using a stock oil pump, TSP uti-lizes an LS6 oil pump (PN 25-12586665M; retail $139.99), which gets ported and its spring shimmed to increase the volume and pressure (10 psi) at all rpm levels. The porting provides extra flow to the main bearings, which is critical in motorsports. Note the pump's oil pickup is lubricated with Red Line assembly lube. To install it, the crankshaft bolt will be removed, the oil pump turned to the correct position and mounted, and the four oil pump bolts torqued to 18 ft-lb. View Related Article
