1. There was an electrical problem in the ignition that caused all my interior electrical equipment to go and and it shorted out my power brakes.
2. I had to rewire the entire stereo system because one speaker shorted out.
3. To change the SC oil I had to remove the SC, which took 4 hours, and all the gaskets and the oil were special orders.
4. Drivers side window is off the track.
5. AC compressor will not turn on. Even after I charged it.
6. Auto headlights don't work.
7. Blower motor is weak.
8. Drivers door hinges need to be replaced.
9. Key will not turn all the way back so I cannot put the car all the way in park.
The SC has more power than the 5.0 but is a very high maintenance car and is vary hard to work on. A normally simple thing like changing the plugs and wires requires you to remove all the air intake tubes. And took me a total of about 4 hours to do.
I love the power. I topped it out around 140 in less than half a mile. it does a 10 second 1/8 mile. 110mph in a 1/4.
Very comfortable car. 10-way dual power seats.
There is a much simpler method to change the supercharger oil than removing the entire supercharger, as you claim to have done.
There is an inspection screw at the front bottom edge of the supercharger, next to the pulley 'snout'. Remove the screw and evacuate the oil with a suction gun, and refill with 6 oz of synthetic supercharger oil.
Ford recommends replacing the oil every 100,000 miles, but I do mine once a year... just to be safe. It only costs about $12 for a 4-oz bottle, so $24 once a year doesn't seem like too much.
