The 9lb pulley goes on the jackshft on the serpentine side. The stock serpentine jackshaft pulley is 8lb. The 2.85 is installed on the supercharger.
I'm running flex. Same thing, e85 90% of the time. The only time I'll be on 91 octane is if I take a trip and e85 isn't available. Seb pulled a bunch of timing on my 91 tune (for safety) and and primarily set me up to make all my power on e85.
