This thread is talking about launching faster, as in 60ft times. Not the entire 1/4mile. 60ft is where the auto wins. High stall converter does nothing for you once you've taken off.

What? A stick car can short time just as well as an auto can under mostly any circumstance, it's all about who's driving it. Ever seen a gear jammer car? Yanking the wheels past the 60' mark with a 4 speed manual.....A converter allows the motor to be looser and keep the rpms up in the power band. Have you ever driven a high stalled car? My last car had a 3600 in it with the stock tranny and a 3800 with a tranbrake with my RMVB TH400. I don't know a lot about them, but I know enough.

+1 to manuals typically putting down more power and being just as capable in a drag race.
But again, it gets back to consistency and dial in in a bracket racing situation. An auto will be more consistent than a manual, even the best driver with a manual will mess up from time to time.

yea im not talkig about the whole 1/4 cause i know the auto is more consistant i was just talking about launching..i figured they would both launch the same...like a 600rwhp 5 speed car on a 2 step vs a 600rwhp auto with the same rpm stall as the 5 speed...who would get to the 60ft first?

Two equally powered cars, one manual and one big stall/tbrake auto, launching at the same time should net nearly identical short times. I'm in the manual car and I hold WOT at 4200 rpms on the limiter, you're in the auto and you're holding WOT at 4200rpms on the tbrake. All I do is let off the clutch and all you do is let off the tbrake button. We both have identical reaction times and perfect traction. Should be almost dead even.

I've seen lots of two steps on autos. They are used for turbos alot of the time (like me, love my 2 step) and alot of the bracket racers. The two step makes sure the car doesn't over power or overheat the convertor also.
A typical set up for alot of the bracket racers is a 2 step, big stall, line lock set up to work on front only or both front and back. This lets the driver launch off the push of a bottun without a transbrake. My neighbor uses this method. His particualr tranny does not like trans brakes so he uses the above method.

one other advantage of the auto in bracket racing is that it is often more consistent with the shifts...even with a manual valve body.
