Maintaining a tight belt and proper belt alignment is critical for any supercharger application. Dorian developed these simple enhancements for the P-1SC's mounting bracket: The washer (left) serves as a shim between the bracket and timing-chain cover and helps keep the belt aligned and tight. The stopper-bolt/jam-nut combination serves as a support for the blower's mounting bracket. Brackets tend to flex slightly under load. This simple stopper is adjustable and prevents the mounting plate from flexing. It also helps maintain belt trueness and tension.
We installed the Ford SVT Focus fuel pump on our Mustang. After removing the OEM pump from the tank, Dorian swaps the sending-unit hardware onto the new pump's canister. The SVT Focus fuel pump is a direct replacement for the stock Mustang unit, and it can supply enough fuel for 8-10 pounds of boost with the Stage II P-1SC and stock fuel lines and rails.
We used spark plugs that are one heat range colder than stock with our P-1SC. Here, Dorian gaps the new NGK TR6 plugs (PN 4177; $1.89/each) to 0.035 inch.
This is an up-close look at the inner workings of a ProCharger P-1SC. The unit is self-contained, which means it's lubricated internally by oil that's manually added during the blower's installation, unlike oil-fed superchargers that are lubricated by engine oil that is usually diverted from the oil-filter housing. Note the temperature probe that sticks just inside the case. Our mission is to determine how hot the oil inside the blower gets and to compare it to the engine-oil's temperature as it enters the supercharger. This calibrated probe will be connected to a dual-channel pyrometer, and a similar sensor will monitor the heat levels of the engine oil.
This is the engine-oil feed line that ProCharger developed for our test. The oil we've tapped from the filter housing runs through the line and into the T-fitting that holds the second temperature sensor. Residual oil continues on through the line and is deposited into the valve cover via ProCharger's mister-nozzle that has been plumbed into a standard oil cap for this test. The mister-nozzle serves the same purpose as a drain-back line that's normally tapped into the pan in an oil-fed, supercharger application.
