Small Block LS Engine Dyno Testing Part II - Big Power, Small Budget
|
A Meziere LS-Series electric water pump (PN MEZWP; retail $629.99) optioned in black is chosen for the dyno. In addition to its 35-gallons-per-minute free-flow rate, the pump will free up some parasitic drag. According to Joseph Potak of TSP, "It's usually good for a minimum of 10 hp on the dyno or street." The electric pump comes with new gaskets and mounting bolts, and a free-floating idler pulley, so the OE belts will work properly. The bolts are torqued in a first pass to 11 ft-lb, followed by a final pass to 22 ft-lb. Next, a thermostat housing is installed. View Related Article
