I don't recall seeing a 0-60 time for a 997.1 without a brake-torque to get into boost. That would be a more realistic figure for just jumping on it leaving a light. I know they say the Tip is faster, but how does it compare w/o a high boost launch?

 

It's much slower without brake boosting

 

My old 997tt tip in stock form did 0-60 in 4.1~4.2 and 3.7 or 3.8 don't remember with brake boost.
