Isn't another function of the two step to hold the rpm when you push the clutch in on a powershift? So that if you do end up missing a gear that you don't over rev the motor?

You don't need a 2 step for that, that's what the rev limiter does. A multi stage rev limiter allows you to have a max rev limit, and a lower launch rev limit.

that's what it is... .how else would you have a multi stage limiter?

I know. I thought he was talking about a rev limiter to prevent over revving at max rpm. A 2 stage isn't needed for that, just a standard single stage rpm limiter. The 2 stage allows max rev limit and a lower rpm limit for launching.

alright so i can understand how an auto may be eventually faster in the 1/4 cause its not like it can miss a shift or anything but why do u say a stalled auto will launch harder than a stick on a 2 step?...isnt it the same thing essentially? just keepin the rpms at a level then take off..

No slipping clutch with an auto. Just instant torque.

I'm guessing you've never sidestepped the clutch in a 400+rwhp car.

A stall converter works to accomplish the same thing as a clutch, the only difference is you don't have to work a pedal to operate the stall converter. There's less coordination involved, that and the stall works off rpm, whereas a clutch pedal modulates clamping force of the disc and pressure plate, generating a whole mess of extra variables when it comes to power transfer. With a stall you can basically launch and let the converter flash up to it's stall speed, and it will stay there until the engine rpm climbs higher, all you have to do is control the power so you don't blow the tires off. The converter stays the same, a clutch doesn't...unless you have a bionic leg.

Sure haven't, good luck with trying to match an auto. Just because you let the clutch pedal fly up on its own DOES NOT MEAN the clutch will fully grab like an auto will. The more power you have, the less likely that is bub.

A manual car will be faster given equal conditions. This is only due to less drivetrain loss. This is pretty basic stuff.

Auto is only "faster" because you can run 100 consecutive 10.4 passes in it. The manual might run 100 passes and have a best of 10.2 and a worst of 33.3 due to a missed shift. The faster the car is, the much more need for an auto. I could pretty much drink a drink and drive my old car down the track before I put the reverse manual valve body in it....but that's for another discussion.

I hope you understand what most of us are saying here.
