10,500 is crazy, but with a turbo that big, its neccesary. Hell terry was revving his to 10,500 2 yers ago on his 700whp b16 lol.
Dont worry bee and danny, the Rome boys are too scared to cross the 9000rpm threshold, i have to yell at them to rev it above that.
if my STOCK GSR rods could handle 9700rpms, then i would expect a forged rod to be able to handle 10,000
