I've got the 9lb pulley, opted for it when buying the kit, will triple check measurement though.

So get these studs also? https://www.z1motorsports.com/engine...hr-p-4755.html

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) - https://www.facebook.com/photo.php?f...20000..&type=3
