My belts came in today, I bought 40", 40.5" and 41" gatorback belts to see what would fit best. 41" fits on great and has tension. I'll be using some extra nuts to raise the supercharger up about 1/4" to put the final bit of tension on. Unfortunately I ordered 5 rib belts by mistake, I need to order a 6 rib instead. At least I've got the tension right though.
I'm also ordering a 5 rib 35.5" belt for the water pump, alternator, and TeakIt idler/airpump delete belt. I'm glad I finally installed that.
Here is the first round of pics from last weekend (please keep in mind these are prior to grinding down/touching up welds. I'll spend the time making them pretty once I know it actually works):
First up, inlet for supercharger. I actually purchased the stock mercedes cast piece and planned to weld my own pipe to it, but due to clearance issues under the UIM, we just made the entire piece from stock.
Flange, will have pipe welded to this side
mates against supercharger, need to grind these down to get a perfectly flat flange.
With pipe attached: This pipe will run under the UIM, and curve up next to the secondary fuel rail where many have their aftermarket fuel pressure regulator located, and then into the outlet of the supercharger.
need to plane this flat:
