Boost/Pulley size for E-85

[65x2]

I'm looking to figure out what size pulley I need to run with my setup on E85.

11.26:1 on a 4.6 stroker (rated to 850RWHP) w/ an intercooled T-trim.

Running a 10% IW O/D pulley as well; at the moment I'm on a 6 rib setup.



Any help would be greatly appreciated.

Thanks,
Luke
