ferrari 308 water pump

Would you trust a water pump for your prized Ferrari that is a 1940's design?

Well here is the deal on 308 water pumps. For years we modified OEM water pumps. we up rated the bearings, we even had a scroll impeller machined out of brass that fit on the skinny little water pump shaft that has a habit of not running true, and we even used to port the pumps for improved flow. The reality was, these were all band-aids for an antiquated water pump design.

With the development of the 3.5 liter & 3.93 liter 308 engines we knew that the Ferrari cooling system would not be up to the task & engine failures would happen unless we came up with a solution.

With my years of experience in water pump modifications & knowing the design's problems & weaknesses, I teamed up with some brilliant people & we came up with a solution.

The first issue was the paddle style impeller; it had to be replaced with a much more efficient scroll type impeller.

I had been running an OEM modified water pump with a scroll brass impeller for a few years & the flow/ cooling was much improved over OEM. With that study concluded, we opted for an ultra lightweight anodized machined impeller for the Forza pump design. Note the difference in picture to your left. OEM impeller is on the left Forza version on the right.

Internal comparison, OEM internals upper left, FORZA version, lower left.

Note how large the shaft diameter is, also note that the components such as the impeller & pump pulley are less that half the rotating weight in our new Forza pump design.

FORZA WATER PUMP COMES COMPLETE WITH LIGHT WEIGHT PULLEY, PULLEY BOLTS, GASKET & O RING SEAL. THIS PUMP WAS DESIGNED TO LAST & DOES NOT NEED TO BE RELPACED DURING EVERY MAJOR SERVICE, DESIGNED TO LAST 100,000 MILES
