Dorian gives our 4.6 a fresh dose of Mobil 1 5W-30 synthetic oil prior to installing the blower and beginning the tests.
When it comes to California's pump gas, this is as good as it gets. Unocal 76's High Performance 91-octane is the fuel we normally use for all the performance evaluations that are done in Cali, and it really is a far cry from the true, high-performance pump gas that's available in other states (oxygenated fuel sucks). We filled up after installing the blower, then began to find out a few things about superchargers-on the road and on the dyno.
The P-1SC requires 6 ounces of a proprietary blower lubricant. This is a fully synthetic, nearly zero-weight oil that should be changed every 6,000 miles.
With the supercharger installed, Dorian makes the final connections for our temperature sensors.
Custom tuning starts here, with the code that's tagged on the factory EEC V. This ID info is sometimes affixed to the passenger-side doorjamb, but, as you see in this photo, it's also attached to the processor. This processor code must be provided when ordering a supercharger system or a DiabloSport tune, as it's a starting point for modifying the factory settings and creating custom parameters for fuel, timing, and such for your Mustang.
Since we had our baseline dyno information recorded-both non-supercharged and supercharged with stock throttle body/plenum-we decided to further optimize the induction system by adding Accufab's 75mm throttle body and plenum for the 4.6 (PN F7546K; $469.99). Note the difference in size and shape compared to the factory parts. The plenum bends smoothly into the intake manifold instead of directing air downward via an extremely inefficient 90-degree angle.
