LS1 Clockwise rotation Billet Water Pump

LS1 Clockwise rotation Billet Water Pump 

Fully serviceable- cartridge can be replaced.

This LS1 Clockwise rotation billet water pump was developed after years of doing LS conversions in our workshop for clients and in our own personal vehicles. The factory LS engine was designed to fit into engine bays such as late Commodores, Corvettes and Camaros and run a whole range of functions not always applicable when retro fitting into an old vehicle. Our LS water pumps are at the core of a range of products designed to maintain the performance and reliability of an LS engine swap without the messy appearance of using a modern motor.

Why is our pump different?

Our pump is designed around running clockwise, same as the old school V8 you always knew and loved. LS1 to current LS engines have a water pump that rotates in an anti-clockwise direction with extra idler pulleys to allow the direction change. Our clockwise rotation pump means the pump pulley rotates in the same direction as the crankshaft. This eliminates the need for idler pulleys and frees up space in the engine bay with the added benefit of having different water outlet options.

When used as part of our front drive kit it helps achieve a more compact low mount accessory drive system that is ideal for small cars and those with narrow chassis rails.

Everything is of the best quality, because we believe parts should fit perfectly and be built to last!

Plumbing 

The top thermostat housing can be interchanged for any of the below

• #1 Angled outlet with 1-1/4” 20 Thread
• #2 -20 AN fitting outlet
• #3 Hose outlet: suit 38.1mm / 1.5”
• #4 Hose outlet: suit 44.4mm / 1.7”5

Connecting the water pump up is easy as the inlet (#1) has been machined in 1-1/4” 20 Thread to suit both aftermarket and our own short-style screw in billet fittings which being compact sized help make plumbing a breeze. (You may also use Speedflow / Aeroflow style water fittings). Using these fittings gives the choice of using rubber hoses or braided hose with AN fittings.

Each pump is supplied with a Tridon thermostat – opening temp 91°C / 195°F

The pump features allowances for two -8 ORB port fittings for heater inlet and outlet. Optional blank off fittings are included with pump.

We also manufacture billet screw in fittings to suit a rubber/silicone hose, we’ve made them shorter than the other after market ones which helps when working in tight spaces. You can choose to add these on when purchasing this pump.
