It works out to be 40% overdriven with my pulley combo.

If you are using lsa injectors, you absolutely will need to. Since you are still on the stock upper I would run a 10 or 10.5 personally.
I figured doing the lower et.al would make more sense for me. Also doing 85#injectors. I'm beefing up the drive line first, then the Ron Davis heat exchanger before doing any more boost - it gets too hot in Texas to not address that). Like the idea of splitting out the belts... May do the exchanger and belt at the same time...

Thanks for the insight!
