We replace all the plungers and barrels on all our rebuilt pumps to prevent gasoline from seeping into the engine oil. Our pumps include upgrades to correct several original pump design defects. After re-assembly each pump is installed on our test bench and run for more than 8 hours that simulates actual engine operating conditions. Fuel calibration is set to less than 1% differential between cylinders at selected speeds and load points. This results in more Power, fuel mileage and reduced emissions.
Our Brass Hex Nut and Alloy Wrench replace the difficult to adjust factory fuel solenoid. Due to tough emission laws, the injection systems were designed to be tamper proof. Anytime the injection pump is serviced or replaced it is necessary to re-set the air/fuel mixture. The original fuel solenoid lock nut was designed to require a large, deep-socket spanner tool. We produced a limited supply of special aftermarket spanner sockets until costs became prohibitive.
We designed a new Hex Nut to allow use of a short wide-mouth wrench that allows using a 19 mm end wrench on the end to firmly seat the large brass hex nut. You can now make air/fuel adjustments without removing the air box/air cleaner.
The nut and wrench are precision CNC Billet machined tools designed to last the life of the vehicle. The new brass nut and hardened alloy wrench are now included on all our rebuilt pumps that have the threaded fuel solenoid.
You can now upgrade your existing Spica pump by purchasing our Do-It-Yourself tune up kit: Our Spica Book, Nut and Wrench is listed on our price list.
For factory stock engines with original cams the best pump is the pump model type originally installed on the vehicle. The original “69” 4C single solenoid pumps are every bit as good as the later 2L pumps. The backfiring defect on the 69 pumps is corrected during rebuilding.
Our HP (high performance) Spica Pumps feature a 4th dimension fuel curve in the pump “Logic” section that improves the air/fuel ratio at high rpm.
Confused about cam timing? Please contact us before you decide.
There are no new magic cam profiles, but the mysteries of performance cams remains legendary in the minds of many car owners.
Send all the details of your engine upgrades. We will assist you with the selection of cams that are correct for your engine and your driving style.
Whether carbureted or Spica Injected, the factory designed “individual throttle per cylinder” intake system is a feature usually found on rare and exotic vehicles. As compared to a single throttle plate in take system, throttle per cylinder intakes are much more forgiving, allowing engine upgrades and more robust cam timing. Idle quality can be very good especially on highly modified HP Spica systems.
You can plan on a 25% to 35% power increase with your street Alfa running 92 octane pump gas.
