Hard-to-find parts and part numbers

Ford synthetic supercharger fluid.  4 ounce bottle.  Two bottles required to completely fill supercharger.  A label on the bottle warns "contains chemicals known to cause cancer".  Handlewith care.  Ford part number E9SZ-19577-A. Price varies from $15-30 CAN depending on the dealer. 

GM supercharger fluid for Pontiac GTP.  This fluid can be used in the SC.  Use at your own risk.  I suspect, but cannot confirm, that this is a non-synthetic fluid.  The Ford fluid is rated for the "lifetime of the supercharger" and according to Ford, never needs to be changed, only topped up if low.  The GM fluid needs to be changed every 30,000 miles (48,000 kms).  Sold in 4 ounce bottles.  Two bottles require to completely fill supercharger. GM part number 12345982.  Price approximately $5 CAN. 

Intercooler Sealant Tape.  This includes enough tape for several applications. 
Ford part number E9PZ-6F091-A.  Price is approximately $40 CAN.

Steel tensioner idler pulleys.  This is a 3 inch steel idler pulley instead of the original 2 7/8 plastic pulley.
Use the old bolt without the old washer.  You can replace all 3 tensioner idler pulleys using this part. 
Ford part number YS-233. List price: Approximately $20 CAN.

Shorter supercharger belt to help eliminate slippage with 10% overdrive supercharger pulley.
Part number 080390.  Available from Gates or Dayco.  Gates manufacturers the original belts for Ford.  Dayco offers a Poly-Cog type belt which will not show cracks like the Gates belt does.  Installing a 3" idler tensioner pulley on the supercharger drive belt should eliminate all slippage.  You can buy a new pulley from Ford, part number YS-233, or swap the smaller supercharger tensioner pulley for the larger one used on the accessory drive belt.
