well, I can honestly say that my stock clutches do NOT like 12psi, and for that matter, neither do the local mustangs. Despite the transmission, the engine LOVES the 12psi.....I guess it's like an asthma victim getting an inhaler....hahahah

Further pushing me along is that ZZP's TT Gran Prix just hit 9.3 @ 150mph in the 1/4 not too long ago...two things are all I can think of to say at this point 1) "Wow", and 2) I better get it in gear (literally)
Here's the link to where I stored/uploaded the videos on that TTGP
