Thanks guys, another mention, I drive my car once a month if lucky
so very little miles get done on it overall, are those pulleys right though? (previous threads I've seen them mentioned to get another 2-3psi) I'm only hitting 10 psi right now on current kit, straight through exhaust at 7k rpm~
I've got the 9lb pulley, opted for it when buying the kit, will triple check measurement though.
So get these studs also?

redondoaveb - I see you have 680whp/530ft.lbs, what over and above have you done to get there?
I've done all the basics E85 fuel only - a2a upgrade/upgrade impeller/s1.se return fuel/larger pump/injectors/9lb stillen pulley, how'd you get 19.5 psi? what pulley changes are needed?
dyno graph is here pretty sure my FB is all public (keep in mind I am in Australia, our dyno's seem to read about 10-15% lower for some reason, so not chasing just a figure only but at least boost should be similar) -
