Power Shifting

So I've been curious about this. I know it can be done, but can it be done safely and is it that much quicker? I've still got my stock clutch and it's got plenty of life left in it.

Obviously this is for track racing (drag) purposes and not for daily use.

Keeping your foot on the gas as you push in the clutch and upshift. I'm not interested in clutchless shifting if that's what you thought I meant.

You can always have fun w/the short-shifting and then replace everything when it goes ka-blooey.

Well, I do have a TWM STS, and I've been working on my speed shifting for awhile. Just trying to find ways I can improve and be quicker.

Umm, there really isn't anything wrong with that if you can shift fast enough, the key is that you don't want to go up more than like 300rpms or so. LNF's came from the factory with the NLTS (No Lift to Shift) option, which is just that, and you had .3 seconds to get to the next gear (if that tells you how fast you have to shift). By doing that you really don't increase the RPMS's to the point where it is hard on any of the driveline. So yes, you can do it, and yes it can help. NLTS'ing on the SS/TC's will shave about .5 - .75 seconds or so off your time in the 1/4 mile (depending on boost and setup and whatnot), however, it's not as impressive in the NA's or SC's. They only shave about .1-.3 off. Nothing too impressive or nothing you can really feel a difference in.

I see, well any bit helps as long as it doesn't threaten my safety and the drivetrain. I'm very confident I can shift into even number gears (1→2, 3→4) within the time limit, but the odd gears might need work as the throws are more complex and longer.

No, I'm not quite sure what you mean. The shifts are short and accurate, almost notchy I'd say, and you defiantly have to go around 'the wall' when shifting into odd numbered gears because it'll block you if you don't throw far enough. I used to have big trouble engaging 1st at stops, especially when cold, but that was remedied somewhat by new tranny fluid (Dexron VI). Car never popped out of gear either.

I drove my buddy's 2001 S4 and it's like the linkage is made out of rubber bands.
