I also redid the supercharger intake pipe. For last year's deals gap I was running out of time and kept having to hack this pipe up to clear the oil fill pedelstal. I ended up still not getting it to clear and having to bash the piece with a hamer to make it clear.

Now that I've relocated the oil fil, and have the extra clearance from removing the oil fil pedestal completely, and blocking the hole off with a freeze plug, I remade the piece the way it was originally supposed to be. The dipstick was another obstacle, but I made it around it. Even ported it all on the inside for nice smooth flow:

This piece was extremely complex. The clearance at the back of the supercharger was tough, and then the pipe has to curve up between the alternator and UIM to go to the turbo. Space is supper tight there, as the engine block gets in the way (the raised part on the front iron with the two bolt holes on it), as well as the secondary fuel rail being an issue. But I finally got it to work.

I also finished the primary fuel rail/vacuum block. The rail is from CJ Motorsports, and I modified it's spacers to hold my vacuum block. This vacuum block has one -6 AN bung that connects to the UIM, from here, all -4AN lines spider out to everything else (boost controller, FPR, blow off valvle, etc...), and one -6 AN line to the brake booster.

This started off as a 1 foot long 1.5" square piece of aluminum stock. All machining done by my trusty drill and sawzall and when that died i toughed it out with my hack saw haha.
