We will find out on Saturday 
I have always been top end limited...essentially coasting through the last few hundred yards of the 1/2 mile because of the 997.2 stock fuel system limitations. There was some custom adjusting of the tune to prevent fuel limitation issues above 150mph but power needed to be cut back at 150 to prevent the system from drying up.
The new fuel system has been on my car and been through dyno testing only. I need to get it on an airstrip to do more thorough testing, which happens this Saturday.
Will run it at the same 600-ish wheel HP but no top end limitation now so should finally get a good 1/2 mile reading finally.

Good luck!
167?!?!? I'll be upset if I don't hit 170+
600 is on a very low read dyno. A 616 wheel (same dyno) 997.1 on Champion 68's already ran 174.
I have factory stock turbos so I don't think there is anyway I can do a 174. A P 918 does 172-173.

This weekend is shaping up to be a great turnout for the 997 tt guys at Shiftsector i'll be running Saturday looking forward to seeing everyone there.I usually tap out around 163 mph up there ,but hoping to get some more out of it this time with some new goodies.But as usual have some last minute tuning going on so who knows .
