This Custom OVERDRIVE Supercharged Pulley was designed for 3800SC Engine by my friend Terry Kelley.
It increases the supercharger boost from 9-12 psi to 15 psi and also lowers the RPM needed for the Supercharged to reach it's PEAK output, thus broading the engine's torque band.
[Needless to say, it's even harder to keep from burning the tires to shreads now]

This is the new Supercharger Pulley installed and ready to go. The Supercharger belt did not require changing.
The spring loaded tensioner takes up the slack.

This is the Cold Air Intake System that I designed myself. It is made from 3 1/2" inner diameter
Aluminum Exhaust pipe. The welding was done by my local exhaust expert. There is a REASON for the
"L" shaped bends instead of "S" shaped mandrel bends. The engine compartment space limits the amount of
room left for "pretty" bends, plus, with 3 1/2" inner diameter pipe, flow is NOT an issue.

Cold Air Intake is 2 pieces to make for easier installation

The intake was polished with a drill-mounted wire wheel and "Mother's" Brand Aluminum Polish.

Cold Air Intake (Viewed from Driver's Side Fender)

The Cold Air Intake Protrude inside the Driver's Side Fender and captures cool
air from underneath the car AND from behind the bumper.

Finally found the PERFECT spot to mount the "NOS" Fuel Pump.
Some version of the 3800 Supercharged Engine have MAP sensors. My particular version does NOT.
I used the brackets for mounting the MAP sensor to secure my "NOS" Fuel Pump in a safe location.

In case you STILL haven't found the pump, look right above the "3800" imprinted in the Engine Cover.
My fuel system uses a BOSCH intank fuel pump, which freely flows and feeds the "NOS" Fuel Pump.
The "NOS" pump is rated at 45psi with a flow rate of OVER 250 liters per hour (67 gallons per hour)
That is MORE than enough to feed this FORCED INDUCTION ENGINE.
