FINALLY A HIGH PERFORMANCE COOLANT PUMP FOR LSI/LS6 ENGINES
EVANS COOLING SYSTEMS, INC. continues to expand their product line with the release of a high flow coolant pump and pulley combination for the hot-running GM LS1/LS6 engines. The new LS1 Coolant pump and pulley combination, part number EP3913, is designed to fill the current void in the LS1 Aftermarket. Flowing over 20 percent more than the OEM style replacement pumps, the EP3913 maintains equal flow to both cylinder banks at any engine RPM. OEM style pumps do not.
Evans has improved the design of the OEM casting to include a Billet pulley hub, heavy-duty 3/4" roller bearing, and ceramic shaft seal. The EP3913 also includes the Evans 3.8" OD 8 vane scrolled impeller to reduce parasitic horsepower loss at high RPM. A new shorter serpentine belt must be purchased separately for the specific application. Belts are available through Evans Cooling Systems for $49.95 each. (Please specify Corvette - EB3913-C or Camaro / Firebird-EB3913-CF.)
The EP3913 is available for $469.95. Corrosion free ceramic-coated housing is available to finish the look of the pump in a show car. Ceramic coating is done on both the inside and outside of the housing. Ceramic-coated pump is available for $594.95. Evans can also build a pump from your existing LS1/LS6 housing for $399.
To take full advantage of the increased flow capability of the EP3913, Evans has developed modified 160° (E3022) and 180° (E3023) thermostats specifically for use with the EP3913. The modified Evans thermostats flow up to 55 percent more coolant than other aftermarket thermostats. Both the 160° (E3022) and 180° (E3023) thermostats are available for $69.95 each.
