G6ET drags

Hey guys, i have a g6e turbo with 320rwkw. i took it to the drags and got a best time of 12.2 launching @ 1,500RPM.
I was afraid to go any higher incase i twist my tailshaft. im going to get mine upgraded, but i was wondering if theres anything that would be likely
to give up if i launch under boost?
