P1SC with Custom Bracket
The bracket looks great, nice job!
You're going to peg the maf but most tuners know how to work around this, without having to go speed density. We have kept the maf on a lot of horsepower builds up through 700 rwhp without any problems. Bob

Thank you for the compliment Bob!
Hopefully the tune will get all squared away before too long. Just have to be able to find the time both the tuner and I are free to get together.

Are you asking how it is put onto the car compared to the SDCE or how does it perform compared to the SDCE?
There were some design aspects of the SDCE that I personally thought could have been done better.
- Spacing the pulley so far off the tensioner arm places undue stress on the system. Twisting loads tensioners were not designed to take. Mine keeps the pulley right next to the arm as the manufacturer spec sheets recommend.
- I did not have an ATI bracket to have modified so that would have been added expense.
- Special tools needed to operate the tensioner. I can use a standard 15mm open wrench to operate my tensioner.
- ATI & SDCE both not using the second 3/8" mounting hole on the super charger. My bracket is wider and using the 6th bolt hole completely ties in the top half of the bracket with the J section.
just something to watch out for is the bearing speed on that little idler you have on the stand off. with the bearing being that small its gonna see a lot of RPM and that means heat/failure if the bearings not up to the task. Not picking your design apart, just pointing something out 
You are correct. The smaller pulley will see upwards of 28000 RPM at 6500 engine RPM, and 30500 rpm at 7000 engine RPM. I spent a lot of time with my bearing supply finding a sealed bearing that is rated high enough to handle the speeds.
