Test it and see where you're at. I think you'll need 23,500+ blower RPM to make 1,100RWHP. This is assuming you have an aftermarket cam, decent heads, and a decent flowing exhaust.

Really now? With a 90mm/9.06 combo I'm making low/mid 900s @ ~15psi.
I figured 75/9.45 would easily yield enough boost. Perhaps I'll go with the biggest common lower I see without relocating anything, the 9.84.
Then I'll play with upper pullies starting with a 2.85 until I see the magic 11xx. Biggest concern going smaller on the upper is belt slip since I'll be using an 8 rib setup.
