I'm planning on running about 12psi-1bar with a 2mm thicker headgasket, arp headstuds and a blockguard. There's a guy on hondatech pushing 16 psi on pump gas putting down 302 whp on the SC50. He finally killed the motor @ 20 psi from a warped head and hydrolocked it (not even from overboosting)

Oh yeah he did it on the AFC hack also not even standalone, i'm not gonna run that much boost maybe 10 daily 12-14 on race gas. Should still make some healthy mid to high 200 whp numbers.
