eh... you guys worry too much. hundreds and hundreds of full throttle shifts later, my original 2009 trans synchros are working just as well as when i bought the car. Almost 9 years later, the 350z trans working just as well also (that trans has a scratch into 5th gear that has been there for eternity though, probably unrelated as its not often to hit 5th when racing). Both cars over 500rwhp and constantly power-shifted their entire life. If I bothered to floor it when accelerating, then I probably didnt let off the gas when I shifted.

If you have a lightweight racing clutch, like most twin disks, the lighter and smaller diameter disks reduce the work on the synchros by drastically reducing the rotating weight on the input shaft. This may be a big factor into why i dont have a problem with it... both cars had a twin disk put in very early in their life. With a stock flywheel, my 370z would make a huge THUD on a powershift, as im assuming the dual mass flywheel was "bottoming out".

people have ALWAYS told me that my trans is going to fail from doing it, but i just keep on doing it, every day, and it just keeps working fine. Hell I havent even changed the trans fluid and im almost at 50,000 miles now.

IF you can drive it right, based on my own experience and evidence, i see no reason it should fail any sooner than mine (which has yet to happen). Besides, a new trans for these cars is pocket change compared to all the other costs associated to FI, so even if you cant do it well, its not that expensive to refresh that trans every few years.
