HP pumps are a very popular option that exists for owners of modified Alfa motors. The HP pump matches the fuel metering characteristics to the breathing mods done to the engine. You wouldn’t throw larger cams in the motor without increasing jet size, would you? Without modifying the pump’s fuel distribution curve you won’t maximize the potential of your improvements.

The heart of the HP pump is the re-profiled 3-D cam. We’ve developed several styles of the 3-D cam to deliver correct fuel mixtures at all engine speeds. It is necessary to specify the engine mods and power expectations on custom orders. Note that the 40mm throttle bodies are available for all SPICA cars and particularly those with modified engines.
