POLL: Powershifting So which do you do and why?
When I say powershifting, I mean pushing the clutch in but leaving the pedal to the metal. Basicly not letting up on the gas.

im sure its hard on the clutch. after 3-4 times doing it to learn how, i only do at the track, not very often that i go, or if its raceworthy on the street, looks like i wont be doing much of anything since i "need a new clutch".
Never. Its not just hard on clutch. There are other parts that can be stressed more than need to be. With the right technique and practice you can be just as fast with a speed shift, and not risk breaking the same ****...

I tried powershifting vs speed shifting at the track and I didn't gain anything, mph stayed the exact same. If you speed shift as fast as you powershift, you won't gain **** in the 1/4 by powershifting, it's not worth the toll it takes on the tranny. JFYI, ever since the last trip to the track powershifting, the tranny doesn't shift as smooth. 
Maybe Well, I've done it a couple of times but just because of the sheer fact that the plates are engaging and such a high rpm when the gas is to the floor, I don't think it's too great on the clutch. Pretty much you're forcing the clutch to engage and a higer RPM than what it's meant to catch at, which will cause more strain. Just my opinion.

Only when racing and generally 1-2 and 3-4....cause I suck and have missed 2-3 too many times that killed my times (can you say rev limiter)(lol)
First time I went 1-2 the rear almost broke away from me....and probably would have if I had a few more ponies/torque

I used to do it ALL the time. I loved doing it and had it perfected. After my clutch wouldn't release fast enough it would grind a bit cause it was taking longer for the clutch to fully disengage, and I was ready for it to be in the next gear before it was. This took a toll on my tranny and I wound up having to rebuild it after it got stuck in 4th.
So a rebuild and new TEXtralia clutch later and I don't do it anymore. I am confident that IF the clutch was disengaging RIGHT when the pedal went to the floor and you didn't screw the shift up I think it would be ok. But the timing must be so precise that it's nearly impossible to keep from increasing the wear on the syncros.
I have gotten real good at speed shifting and have seen good results on the street and at the track, so I will stick with this method.
With that said it's the tranny, not the clutch that you should be worried about if you powershift.

I used to do it all the time down the track until I learned how much of a toll it takes on the trans. After a rebuild I don't do it anymore except maybe the 3-4 sometimes. Proper speed shifting is just as fast and is a helluva lot easier on the trans. To the guys powershifting all the time I hope you can rebuild your own trannys or it's gonna get expensive.
i used to powershift allot cause i knew my tranny needed a rebuild anyways so i didnt care, course at rebuild time i needed more stuff and the cost went up a few hundred but the more new stuff the better right. but now i wouldnt think of powershifting, even with my new beefed up tranny and new clutch
not only do i keep the petal to the floor but i hardly even blip the clutch at the track, that the benefits of straightcut gears 
definalty worth et since you dont lose any momentum, i could hear and see a difference in my shifts vs a normal tranny on video
