A great supercharger. I had mine professionally installed on my 2000 GT when the car had 60,000 miles. The one problem was that the previous owner had installed under drive pulleys. The supercharger will not physically fit with the over-large water pump pulley so I bought an electric water pump to replace it.
I didn't like the original tune. They did a work around in the tune for the stock fuel pump. I bought a Meizere Electric Water Pump, BBK long-tube headers and catted x-pipe and had the car re-tuned.
The car is a daily driver. It currently has 210,000 miles. It was a mess changing oil in the head unit until I bought an extension drain line. Changing belts I once lost a spacer and got the pulleys out of alignment. It shredded the new belt. The shredded belt damaged the ProCharger seal behind the pulley and cracked the timing chain cover. I had the timing chain cover replaced and replaced the seal myself. I was very careful about pulley alignment after that.
Other than operator error I've had no problems in 150,000 miles of spirited driving. I change supercharger oil every 5,000 miles at the same time I change motor oil. ProCharger has a special oil. I use 6 quarts of Mobil's European Blend 0-40 synthetic oil in the motor because it has the levels of ZDDP that was in oil when the motor was manufactured. Other oils have reduced levels.
The 2000 manual says to run 5 quarts. 6 quarts were recommended for the 2001s. The pan easily holds 8 quarts. There were reports of motors running dry with 5 quarts during high rpm operation. Instead of always showing one quart over when checking oil I bought a new 6 quart dipstick.
The car had around 160,000 miles on it when I got the pulleys out of alignment. When they changed the timing chain cover I was going to replace the guides . The mechanic said that everything looked great and nothing needed to be replaced.
I would recommend the ProCharger P-1SC for any moderate horsepower build. I bolted it on an internally stock 4.6. At 8.9 psi it made STD 396 rwhp (approx 440-450 at the block) and it ran a 12.7 quarter mile. It is perfect for a daily driver.
ProCharger P-1SC, 9 psi, STD 396/383; Uncorrected 388/375; SAE 383/370.
