i have never run a FI car, but to keep up rpm's and boost some people do it, and i did occasionaly do it on my Spitfire during races but it had low power.
i think in the Z you would wear it out alot faster, BUT, if you are racing at the track and are willing to sacrifice for speed it will net you a couple 10th's of a second

More seriously, the worst that can happen would be a loud noise from your trany as it grenades itself trying to be into 2 gears at once. The car would just stop rolling, rear wheels locked.
Less worst would be a busted synchro, killing one gear (at the others once metal shavings start going everywhere.)
It really is not as fast as some might want to believe. And it’s just hard on the whole drive train.
It’s your car, do what you want with it.

I have powershifted when racing since I was 17-done it on every car ive driven/raced. 53K on the stock clutch when I pulled it out, never slipped 1X, even with 6000rpm launches on slicks. To me, powershfiting in the Z is not about dropping tenths off your 1/4, its about personal preference. I got to the point with my shifting, that even with a VERY quick lift off the throttle when switching gears, it felt like it slowed me down. So I eventually started powershifting. Now it just comes natural. When done correctly, you dont even jump more than 200rpm's and in some cars(like stock turbo cars Evo's, GTI's, etc) you get good gains from it, from boost not falling during shifts. I dropped .8 tenths off a buddy's time down the 1/4 in his bone stock 1.8T with only a .1 better 60ft (14.6 @ 95mph with a crappy 2.2 60ft-which I think is a record still on the VW bboards lol). I did have problems with my tranny at first, but my car is an 03' we all know the issues, I wouldnt blame myself for the synchro failure-chalk that up to Nissan. My latest tranny, which has over 20K miles has never given me issues, nor has my stock or JWT clutch now. When done correctly, I dont think it will *** up your car. Any racing/fast shifting will prematurely wear your tranny/clutch down, but to me its not enough to not do it. Thats my

I might not be as hard core as Alberto, but I powershift my car very often. I wouldn't say i powershift everytime i shift, but definately every time I am driving my Z, i powershift a few gears. my Z is a 2005 with 13K miles, not a single problem YET eheheheheh. and i definately jumped more than 200rpm when i powershift but way less than 500rpm.

When powershifting your suppose to shift right at the rev-limiter. If you do it before then and of course your going to bounce once, if not twice off of the rev-limiter on your shift. You just need more practice and to really eye ball your TACH! Good Luck!

Powershifting requires using the clutch! Put the gas pedal to the floor and keep it there. You should be pressing the clutch in simultaneously as your pushing or pulling the stick into the next gear. Your to do all this at the same time when you hit the rev-limiter. Your shift will be faster than normal as I would say like a knife cutting butter and it will be in the next gear faster than you know it. You will be shifting faster than speed shifting the normal way. Good Luck!

power shifting as i have always known it is not using the clutch. can be done on older manuals or straight cut gears, but a huge no no on newer helical cut gears. you will grind smooth your syncro in one or 2 tries like this.
now just not letting off the gas when you shift is just proper shifting when you need to "git 'r dun". i do about a half clutch as quick as my foot will move and that is enough to get the syncros to line up and not grind.

Powershifting (No lift/ redline shifting) when drag racing used to be a necessity if you expected to win. Now many/most serious racers run autos. Roadracers don't powershift. Powershifting is one the best way I know to distroy a street car. Miss a shift and you will probably badly screw something in the drive train. Also, unless you are at the strip, what's the point? Needlless abuse of the equipment.
